-> ''Quintili Vare, legiones redde!'' ("Quinctillus Varus, where are my legions?")
-->-- '''UsefulNotes/{{Augustus}}''', the first Emperor of Rome's restrained reaction to the loss of the Battle of Teutoberg Forest.

In fiction (and in RealLife) during a great war there's a certain strategic loss that is very significant to the point of being demoralizing, shocking, and iconic in universe.

As an example: TheFederation is fighting an intergalactic war against ScaryDogmaticAliens, but there's [[TemptingFate one place in the galaxy that has no chance in hell]] of ever falling at the hands of the enemy: A [[PlanetSpaceship planet-sized starship]] that's armed with [[WaveMotionGun weapons of]] [[EarthShatteringKaboom mass destruction]], fortified by thousands of [[KillSat automated]] [[AttackDrone defenses]], an armada of [[TheBattlestar the most powerful]] [[LightningBruiser warships ever built]], guarded by countless [[SpaceFighter space fighters]], [[HumongousMecha mechanized infantry]], and [[SuperSoldier genetically bred]] [[SpaceMarine elite warriors]].

[[ThisCannotBe Said planet falls anyway]], [[OhCrap sending a chilling wave down the spines of the Federation]]. Sometimes it could be a [[DecisiveBattle turning point in the war]], but not always: any faction could suffer a defeat like this and not necessarily be defeated. Perhaps this defeat was due to a [[FailedASpotCheck surprise attack]]. Could have been a PyrrhicVictory for the attackers. Sometimes it's described as a NoodleIncident in some stories. What ever the reason, it's still an incredible loss, and [[NeverLiveItDown no one will ever forget it]]. The defeat likewise can have terrible dramatic consequences because it sets a mentality for [[https://en.wikipedia.org/wiki/Revanchism revanchism]] and trigger a factional fight among groups about who is responsible for the defeat and who do we scapegoat to make sure it doesn't happen again.

This is essentially TheWorfEffect applied to an entire battle or war (or even a sport) instead of individuals, typically used to show how high the stakes are.

This trope usually overlaps with HopelessWar, RememberTheAlamo, and LastStand. Often can be a DecisiveBattle, if the balance of power is dramatically shifted as well. See also the sub-trope CapitalOffensive.

For the victors it could overlap with PyrrhicVictory, and WasItReallyWorthIt.

* End of ''Anime/CodeGeass'' season one when the [[{{LaResistance}} Black Rebellion]] fails spectacularly in the throes of what almost looked like their Finest Hour. HistoryRepeats in season two when the Black Knights are AGAIN defeated, this time by Lelouch, amplified by the fact that it means he now [[{{TakeOverTheWorld}} rules the world]] with an iron fist. [[spoiler: Which is then followed up by him being publicly assassinated by Zero - actually Suzaku in Zero's costume - at his apparent moment of triumph, in order to cement the final step of his [[ThanatosGambit Zero Requiem]]: [[UtopiaJustifiesTheMeans making himself into an effigy of all the evils of the world and then dying, taking all the world's hatred with him.]]]]
* The [[AllThereInTheManual Backstory]] of the ''Franchise/LyricalNanoha'' multiverse describes the loss of the [[TheEmpire Belkan Empire's]] homeworld as this.
* In the later novels of ''[[LightNovel/CrestOfTheStars Banner of the Stars]]'', the fall of Lakfakalle, the Abh capital. Up until that point, the war had been pretty much going exclusively in the Abh's favor, and then their enemies turned the whole war around in a single, utterly disastrous surprise attack.


[[folder: Film ]]
* ''Film/TheSorrowAndThePity'': A documentary about the German conquest of France in 1940, the difficulties of the next four years under German occupation, and how French people are still having problems dealing with it 25 years after liberation. Director Max Ophuls also takes time to interview some of the German generals behind that attack and the latter, despite Denazification cannot help but gloat about their victory.
* The Rebel Alliance from ''{{Star Wars}}'' blowing up not only the first Death Star, but the second one as well.
** Arguably the beginning of the end for the empire was when Tarkin blew up Alderaan. Which caused a huge backlash that led to high rebel recruitment.
** And again with the Battle of Jakku, which put the perverbial nail in the coffin of The Empire.
* The destruction of [[spoiler: Vulcan]] in the 2009 ''Film/StarTrek''. Not only was a massive loss for the Federation, but a signal to the fans that this was not going back to the status quo.


[[folder: Literature ]]

* The Battle of Yonkers in ''Literature/WorldWarZ''. They threw everything but the kitchen sink at the enemy and still lost. Though that was actually a detriment in the end, as all their gear and defenses and tactics were based on fighting an enemy that obeyed no human nor life norms (no pain, no fear, no stopping...)
* The Fall of Coruscant to the Yuzzhan Vong in the ''Literature/NewJediOrder'' series. Under the incredulous eyes of many of the surviving characters, the lights of The City That Never Sleeps go out for the first time in several thousand years.
--> '''Han Solo:''' ''[[TheEndOfTheWorldAsWeKnowIt The end of the world.]] Whodve thought wed live to see it?''
* The Dropsite Massacre of Isstvan V from the ''Literature/HorusHeresy''. Four noble space marine legions had suddenly turned traitor and fortified themselves on said planet (after burning Isstvan III and purging their own ranks of loyalists), an overwhelming seven legions were sent to crush the rebellion before it could spread. Instead, four of those legions turned traitor too, and all of them caught the remaining three loyalist legions in a crossfire that saw hundreds of thousands dead. It went FromBadToWorse from there...
* ''Literature/TheSilmarillion'': The Battle Of Unnumbered Tears. It begins as a noble effort of the Elves, Men, and Dwarves to finish [[{{Satan}} Morgoth]] once and for all. It's the first coalition of all the races together to fight Morgoth, and the greatest army seen so far in the world outside of the gods. It gets crushed so badly and so many people die that Morgoth literally makes a hill out of the corpses. The worst part is that they never had a chance. And things get so much worse from there.
* In ''Literature/HonorHarrington'' these were the [[spoiler: Battle of Manticore]] for Haven and [[spoiler: Grendelsbane disaster during the opening stages of the Second Havenite War and later the Operation ''Oyster Bay'' (though Manticorans didn't knew its official name)]] for Manticore, though both nations recovered from these pretty damn quickly, and with a vengeance.
* Creator/AndreyLivadny's ''Literature/TheHistoryOfTheGalaxy'' series has the nuclear bombardment of the Dabog colony by the Earth Alliance strike fleet as the opening round of the First Galactic War. In fact, this trope was [[PresidentEvil President Hammer]]'s original plan. The fleet would show up without warning, nuke two major cities on the planet, and land troops to quickly rout any defenders. Unfortunately for them, they didn't expect the colonists to have very effective [[RealRobotGenre Real Robots]] that routed the invaders. The pissed-off admiral of the fleet has the planet nuked so thoroughly that 1000 years later it's still uninhabitable. In fact, even after a millenium, the mere mention of Dabog is enough to stop a fight. However, the destruction of the colony only serves to band the colonies together and, after decades of vicious fighting, take the fight to Earth itself.
* In ''Literature/CodexAlera'', the rampant destruction of the Vord War, epitomised by the [[spoiler: obliteration of Alera Imperia, the capital city, and the death of Gaius Sextus, the First Lord]], is certain to be seen as this in the future (though the end of the series means readers won't see it). However, while the Vord War was the worst disaster in Aleran history in terms of casualties and destruction, various characters think that the Aleran culture is likely to improve a great deal in the aftermath, as it shattered many of the prejudices and mindsets that kept Alera stable but stagnant for those that had power and miserably unjust for those that didn't, and the series ends on a decidedly hopeful note.
* In ''Literature/TheDresdenFiles'' the fall of Archangel early on in the Vampire War. A White Council stronghold and [[spoiler:home to one of the strongest Wizards in the world and foremost expert on vampires, who died fighting against the onslaught]] fell in the first few weeks of the war. Later on, it would become the Wizard's equivalent of the Alamo.
* The Battle of the Azure Nebula in the Franchise/StarTrekNovelVerse, the most one-sided battle in the franchise's history.
** To elaborate: Borg cubes had been probing the Federation's outer defenses for weeks, inflicting huge numbers of causalities. An investigation found that the ships were coming from a wormhole in the Azure Nebula. The Federation sent ships there to guard the line if any more ships came out, and were quickly reinforced by the Klingons. Some politics behind the scenes also managed to get aid from many other major powers, even those unfriendly to the Federation. In total, there were over 300 allied ships at the Nebula, and were said to have enough firepower to take on ''ten'' Borg cubes. [[spoiler:Then the wormhole opened and ''over 7500'' Borg ships came through. The allied force barely qualified as a nuisance, [[PlotArmor and only ''Voyager'' survived]].]]
* The Battle of the Blackwater in ''Literature/ASongOfIceAndFire'': Stannis Baratheon, one of the greatest threats to the Iron Throne among all five of the kings fighting for it, besieges King's Landing itself with a huge army, and is only beaten off due to preparations made by Tyrion that hold him off long enough for an allied Lannister-Tyrell army to come in from behind and smash his army so badly that he only has around fifteen hundred men and is now sending out people to hire sellswords to bolster his numbers.


[[folder: Live-Action TV ]]

* The Battle of Wolf 359 from ''Series/StarTrekTheNextGeneration''.
* ''Series/StarTrekDeepSpaceNine'' provides a few:
** The Dominion attacking and destroying New Bajor, and shortly after the Galaxy-class ''USS Odyssey''. The writers invoked this trope to emphasize the Dominion threat - A starship the same class as the ''Enterprise'' stood no chance against this foe.
** The loss of Betazed in the ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'' series to the Dominion.
** The Romulan entry in the war. What happened is not shown, but before that the Dominion was winning the war and on the verge of invading Vulcan, and a couple months later ''every single Federation and Klingon system conquered by the Dominion was back in Federation and Klingon hands'' (many of them overran by the Romulans and turned over to their legitimate owners as soon as they could spare some ships), and the combined Federation-Klingon-Romulan fleet was threatening the Cardassian home territory.
** The Breen attack on San Francisco. Not as damaging as some of the others on this list, but shocking in that they were able to stab at the heart of TheFederation.
** One was planned by the Dominion as the final act of the war. After defeating the Federation they planned to wipe out all life on Earth, believing the demoralizing effect would severely limit revolutionary activities.
*** In some Franchise/StarTrekExpandedUniverse books, this happened in the MirrorUniverse after the Klingon-Cardassian Alliance defeated the Terran Empire. As punishment, and an example, they turned Earth into a lifeless rock, possibly Vulcan as well.
* The Battle of Serenity Valley in ''Series/{{Firefly}}'', which was apparently the battle that lost the war for the Independents and sent Malcolm Reynolds over the DespairEventHorizon.
* In ''Series/DoctorWho'', much of the Last Great Time War between the Time Lords and the Daleks has only been explained through dialogue by the Doctor himself. However, we do have a definite shocking defeat that was said on the show: the Fall of the Cruciform, which was so shocking that it made the Master himself flee to the end of the universe.
** There was another one. The Doctor himself mentions that he was at the Fall of Arcadia, and that he might be able to come to terms with it someday. In "The Day of the Doctor" it's revealed that Arcadia was the second biggest city on Galifrey, and its fall to the Daleks meant that the Time Lords were on the verge of annihilation. This ends up motivating the Doctor to [[spoiler:destroy both races]].
** The Doctor inflicts the demoralizing side of this trope on Colonel Manton after temporarily gaining an edge at the Battle of Demon's Run, forcing him to bear the insulting nickname "Colonel Runaway" by giving his troops the order to run away as punishment for targeting people that he loves.
* In the finale of ''Series/PowerRangersTurbo'', the planet Eltar falls, stripping the Rangers of their powers, forcing them into space to try and rescue their old mentor Zordon.
* ''Series/GameOfThrones'': Despite winning every battle, the fall of Winterfell severely costs Robb Stark in both morale and momentum, eventually [[spoiler: culminating in the Boltons switching sides and betraying him. This fall of Winterfell and betrayal are now what his reign is remembered for. It's Robb's tragic fate that despite being a YoungConqueror and military genius, his reign resulted in the absolute DarkestHour for House Stark and the North in its entire history.]]


[[folder: MMORPG ]]

* In ''WorldOfWarcraft'' there are numerous examples of this, as well as a couple of subversions, but given the name of the game, that's hardly surprising. There is the WarOfTheAncients which led to the destruction of the Kaldorei kingdom and the world splitting apart. Then the Orcs almost complete annihilation of the Draenei on Draenor. After which, said orcs go on to invade the world of Azeroth and sack the human city of Stormwind. Later, they go on to enslave the Red Dragon Flight, with which, they almost reduce Quel'Thalas to burning ash. Later, Prince/Death Knight Arthas ends up killing every man, woman, and child in Stratholme. After that, he kills his father, several paladins, including another father figure, Uther, then sacks Quel'Thalas and Silvermoon City to use the Sunwell, which he then blows up. Oh yeah, at the end of that campaign, Archimonde comes around to completely demolish Dalaran. The Kaldorei lose their beloved demigod, Cenarius, in a battle with Grom Hellscream. Finally, the Kaldorei give up their immortality by blowing up the World Tree to kill Archimonde. Did I mention there were a lot of examples in this?
** HOWEVER the killing of Archimonde, the whatever happened to Sargeras and Azeroth's ability to merely RESIST the Burning Legion are all pretty big. And implied to be bigger than anyone knows. Given this entails two {{cosmic horror}} like beings killed in a setting every (sane) person knows to be a {{cosmic horror story}} its kinda big.
** ''Wrath of the Lich King'' introduced the battle of Wrathgate, where a united Horde and Alliance force was destroyed by treasonous members of the Forsaken. This set back the offensive aginast the Lich King by years and renewed the waning war between the two factions.
** ''Mists of Pandaria'' begins with Garrosh Hellscream destroying Theramore, home to the peace-seeking Jaina Proudmoore. The leader of the neutral Kirin Tor is killed and Jaina nearly destroys Orgrimmar in return. Following these events, Jaina assumes leadership of the Kirin Tor with a decidedly anti-Garrosh mindset.
*** By this point, almost ''everyone'' is pretty much against Garrosh, who has decided that the Horde should be an orc-only force, kicking out all of his allies. A combined force of the Horde (minus Garrosh's force) and Alliance prepares to storm Orgrimmar to take care of Garrosh once and for all. Not a legacy his father would've approved of.
** All throughout the game´s expansions, the Trolls are much of a subject of this: Confirmed to be one of the first races to even be in the World. They had vast Empires, one completely shattered into two tiny tribes by Night Elves, and another almost annihilated by the first Human/High Elf Alliance, yet another, later destroyed by The Scourge in Northrend. They try many, many, many desperately evil things to try and get by, but so far, they do not seem to be able to get a break unless they align themselves with The Horde. And even that does not work THAT well for them...!
* ''VideoGame/StarWarsTheOldRepublic'' contains two examples in one battle. First the Empire takes Corellia (a founding Republic world and major industrial center) out of nowhere; the shock is only enhanced when it's discovered that it wasn't totally a military conquest, and that Corellia's ruling body actually ''defected'' to the Empire. It flips around when the Republic rallies to take Corellia back, and in the process kills off half the Dark Council and a significant percentage of the Empire's military.This was largly due to a frankly ludicrous GambitPileup caused by all 8 class plotlines coming to a head at the same place and time.


[[folder: Video Games ]]

* ''Franchise/{{Halo}}'':
** The UNSC has the Fall Of Reach, which was the equivalent of America's CENTCOM, Norfolk Naval Shipyard, Fort Bragg, and Norad being taken out all at once. And that's not counting the civilian casualties.
** While much of the Covenant fleet sent to Reach was also destroyed, it was their subsequent failure to prevent the Master Chief from destroying Alpha Halo that sent shockwaves across the Covenant, particularly since their commander, Thel 'Vadamee, was one of the Covenant's very best, having remained completely undefeated up until that point. The Prophets ended up laying the blame on him ([[TheScapegoat despite the fact that his orders had been continually subverted by his overseeing Prophet]]) and [[UriahGambit declaring him Arbiter]], starting a chain of events which eventually led to the dissolution of the Covenant itself.
** When Flood overrun the Covenant capital of ''High Charity'', it signals a massive loss for the Covenant, and the turning of the tide in favor of not only the Elites and their subordinates, but humanity's own continued survival.
** After the end of the Human-Covenant War, humanity is one of the major powers in the Orion Arm. And then an entire city on Earth is wiped out in ''VideoGame/{{Halo 4}}'' when the Didact uses a weapon that turns any sentient being into a mindless EnergyBeing soldier. It's only thanks to the Master Chief that he is stopped from doing that to all of humanity. The truth of the attack is completely covered up from almost all of humanity, but UNSC high command is rightfully spooked.
* ''VideoGame/DeusEx'': the (French!) terrorist group Silhouette blows up the Statue of Liberty! [[spoiler: Actually committed by [[TheConspiracy MJ12]] itself, conveniently framing Silhouette in the process.]]
* ''Franchise/MassEffect'' has Shanxi, a human colony that was blockaded and besieged by the turians during the First Contact War until it was forced to surrender. The ''Bring Down the Sky DLC'' has Shepard narrowly avert one, preventing a devastating ColonyDrop by batarian extremists on Terra Nova.
** The Reapers plan for countless [[HistoryRepeats Cycles]] involved coming through the hidden relay inside the Citadel to wipe out galactic leadership and shut down the Relay network, allowing them to easily wipe out all galactic life system by system. Only the final act of defiance from surviving prothean scientists on Ilos prevented this from happening in the current Cycle, having altered the control signal that told the Keepers to open the Citadel relay.
** In addition to the Reaper invasions across the galaxy, the fall of [[spoiler: Thessia]] in ''VideoGame/MassEffect3''.
* ''VideoGame/EveOnline'' has the [[http://wiki.eveonline.com/en/wiki/The_Battle_of_Vak-Atioth_(Chronicle) battle of Vak-Atioth]], a CurbStompBattle between the Jove and Amarr Empires, which sent the latter reeling into VestigialEmpire status. Later on, the Amarr reversed their fortune in the Battle of Mekhios, where they wiped out an entire Minmatar fleet and send the remnants of their forces packing.
* ''VideoGame/DragonAgeOrigins'' has the Battle of Ostagar, in which the PlayerCharacter participates. [[spoiler: Much of the Fereldan army, and all of the Grey Wardens but the PlayerCharacter and TheLancer Alistair, are killed after Teyrn Loghain's forces, TheCavalry, abandon the battlefield.]]
** In ''VideoGame/DragonAgeII'', after the fall of [[DoomedHometown Lothering]] to the Darkspawn horde, Hawke's family became one of thousands of refugees that fled Ferelden to escape the Blight, eventually settling in Kirkwall in the Free Marches. Part of the backstory of a Warrior/Rogue Hawke, their brother Carver and Aveline Vallen is that they were all survivors of the King's Army at Ostagar and only narrowly escaped with their lives after [[spoiler: Loghain's betrayal]].
* In ''Franchise/TheElderScrolls'' backstory, for all of their many victories, it was a [[ProudWarriorRace Nord]] defeat that had perhaps the most profound impact on Tamriellic history. After centuries of domination and expansion out of Skyrim, [[BadassArmy their army]], led by the Tongues ([[MakeMeWannaShout masters of the Thu'um]]), was annihilated at Red Mountain in Morrowind by a coalition of [[OurDwarvesAreDifferent Dwemer]] and Chimer forces. This marked the farthest expanse of the Nordic empire and led to a drop-off in the use of the Thu'um as a weapon after [[HeelFaithTurn Jurgen Windcaller]], one of the defeated Tongues, created the Way of the Voice to use the Thu'um only to honor the gods. The after effects of the loss at Red Mountain could still be felt in the storylines to both ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'' and ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]''.

[[folder: Western Animation ]]
* ''WesternAnimation/TheLegendOfKorra'' Book 4 sees Korra lose to [[spoiler:[[YoungConqueror Kuv]][[TheParagonAlwaysRebels ira]]]] in an arranged duel over the fate of the city of [[spoiler:Zaofu]] (whom Kuvira already amassed an army to take). Since she had previously had a 3-year long Convalescence after being physically and psychologically [[BrokenBird broken]] by the third book's finale, she loses. After she gets better and back into top form, she resolves to not let Republic City fall to Kuvira's conquest too.
* The loss of the Homeworlds for the Terrans in ''WesternAnimation/ExoSquad'', although the [[spoiler:utter destruction of Mars]] late in the second season was an even more devastating blow to the Neosapiens. Phaeton built most of his anti-Terran propaganda upon it afterwards.


[[folder: Real Life ]]


[[folder: Classical Antiquity ]]

* The [[https://en.wikipedia.org/wiki/Battle_of_Leuctra Battle of Leuctra]] for Greece. Sparta was considered effectively invincible after centuries of reputation and their recent defeat of Athens. However, once Epaminondas applied this little thing called "proper tactics"... the conservative Spartans lost a thousand men in that single battle, their reputation and hegemony over Greece both shattered forever.
* From UsefulNotes/TheRomanRepublic and UsefulNotes/TheRomanEmpire:
** [[http://en.wikipedia.org/wiki/Battle_of_the_Allia The Battle of the Allia]] for AncientRome. The Gaulish chieftain Brennus defeated the Roman army and sacked Rome itself. The Romans were determined never to allow this to happen again, and strengthened the city's defences, reorganised the army and, [[SinsOfOurFathers for generations afterwards]], marked the anniversary of the defeat by [[DisproportionateRetribution sacrificing the city's guard dogs as punishment]] [[YouHaveFailedMe for their failure to alert the Romans to a night attack on the Capitoline Hill]]. The sacred geese that ''did'' alert the Romans were carried through the city on gilded cushions in the same ceremony. As it happens, Rome would not be sacked again until 800 years later, the first time in 410 CE by Alaric I, then a second time in 455 CE, but at that time Rome had not been the capital of even the Western Empire for more than a 100 years (it was Ravenna, and before that it was Mediolanum).
** The UsefulNotes/PunicWars nearly came close. In the first, the Romans lost two entire fleets in heavy storms, losing 280 ships and 100,000 men in 255 B.C. and a slightly smaller number in 253, yet they kept building new fleets and wrested naval supremacy from Carthage. In the Second Punic War, Hannibal and his army inflicted three terrible defeats on the Romans, but Rome continued to wage war until ultimate victory. Still the reaction to the loss of Cannae was desperate enough that Livy mentions that the Romans indulged in HumanSacrifice to the Gods: Two Gauls and two Greeks in male-female couples were buried alive in a stone chamber (normally used to bury alive as punishment Vestal Virgins who broke their vows of celibacy). So it was psychologically a huge blow, and it took a while for the Romans to come BackFromTheBrink.
** In the early imperial era, the most famous was the Battle of Teutoburg Forest on September 9, 9 AD. Three Roman legions were returning to camp when they were attacked by Arminius, a Germanic chieftain who had grown up in Rome. All three legions were wiped out, and eventually the Roman Empire withdrew from Germania. Emperor Augustus, when told of the disaster, as per Suetonius, banged his head against the wall, shouting "Varus! Give me back my legions!" went days without shaving in a HeroicBSOD and years after was known to mutter as a non-sequitir the same line, despite the fact that Varus had died in battle (mercifully since he didn't [[YouHaveFailedMe have to face Augustus]] in person). This defeat is often cited, especially in Romantic German nationalism as the real reason why the Romans never went further into Germania. Of course, the Germans did make excursions and expand there under Marcus Aurelius (a fact which ThePhilosopherKing comemorates in a column showing him personally slaughter Germans) and there are some archaeological findings that suggest the Romans did try again but that defeat did endure in Rome's psyche.[[note]]More recent research, e. g. the finding of the remains of a post 9 A. D. battlefield in the middle of Germania where the Romans conclusively defeated their Germanic foes, indicates that Rome continued to make successful incursions into Germania much longer than was hitherto believed and that the eventual withdrawal from there was, perhaps not directly preconditioned on the battle of the Teutoburg Forest.[[/note]]
* The real humiliating defeats for Rome came against the Persian Empires. Rome and the Parthians and later the Sassanians had a ForeverWar that lasted 683 years, the longest protracted conflict between two powers, and that [[GiantSpaceFleaFromNowhere ended when the Arabs came out of nowhere]] and took out the Sassanians.
** The first and most humiliating one was the Battle of Carrhae, where triumvir Marcus Licinus Crassus (the guy who crushed Spartacus) invaded the Parthian Empire. He had a solidly equipped army and greatly outnumbered the Parthians, yet the latter's cavalry and horse-archers (what the Byzantine Romans would call kataphracts) were too much and Crassus while a good general with some moments was not a genius, and he really needed to be one. The Parthians brutally crushed the Romans despite being outnumbered, Crassus was murdered and depending on which account you believe, molten gold was poured into his mouth or he was beheaded and his head was used as a prop for a Persian production of Creator/{{Euripides}}'s ''Theatre/{{Bacchae}}'' (Crassus was apparently the head of King Pentheus in what we can assume was a rather intensely realistic production).
** The Romans [[SkewedPriorities were especially upset that the Persians captured their Eagle standards]] and UsefulNotes/JuliusCaesar planned to invade there to get it back, but he got assassinated. Mark Antony decided to launch the invasion later and he also got defeated, worse than Crassus (albeit not in the same numbers), and UsefulNotes/{{Augustus}} used Antony's defeat to forge a peace treaty with the Parthians and managed to get the Eagles back to Rome, which boosted his popularity. It was such a huge deal for him that he built statues to commemorate it. He also minted coins showing a Persian soldier kneeling submissively which needless to say didn't happen but obviously was important for the Romans to believe.
** Then there was the famous incident where Emperor Valerian lost to them in the Battle of Edessa and ended up becoming [[EpicFail the first Emperor to be captured alive and imprisoned by an enemy power]]. Valerian spent the remainder of his life in captivity and according to Roman legend was either made to serve as a footstool to King Shapur of Persia and/or given the Crassus-esque molten gold treatment. The Persians denied that they killed him however. Another one was the Emperor Julian the Apostate who led another invasion into Persian land, supposedly to imitate UsefulNotes/AlexanderTheGreat. Julian had some successes early on and laid siege on the capital of Ctesiphon before being killed by a Persian spear (of if you believe ConspiracyTheory, fragged by one of his own Christian soldiers because they didn't like his pagan-revival policies). In either case, the death of the Emperor and Head of State with his arm in enemy territory was a major embarrassment, and his successor Jovian more or less negotiated a sweetheart deal for the Persians to get himself and the army safe-passage, which made him so widely hated in Rome that his own uncle was lynched the day it was announced.
* The Battle of Red Cliffs, as it's widely believed that if the aggressors hadn't been defeated, the Three Kingdoms period might have ended then and there, which would have had a drastic impact on China's history.
* The Battle of Fei River. Had Jin lost, the Han Chinese could have lost control of China, however, Xie An (who was famous as a great administrator and had little military experience) decided he wasn't going to let Former Qin [[TookALevelInBadass run wild]] and [[CrowningMomentOfAwesome beat back a far more experienced army well over twice the size of his own]]. It was the single largest catalyst in the fall of Former Qin and just ten years later practically ceased to exist.


[[folder: Middle Ages ]]

* For the English at least in later eras (when they started prattling about the "Norman Yoke" an utterly made-up concept) the Battle of Hastings came to be seen as this. Hastings is a perfectly [[JustifiedTrope justified]] example, in that the King of England got an arrow to the head and his troops [[TooDumbToLive kept falling for fake retreats]]. Since few people really cared who was king at the time, William the [[strike:Bastard]] Conqueror pretty much won by default.
* The Battle of Bouvines was another major defeat. The French King Philip II Augustus defeated a coalition of England, HRE and Flanders and UsefulNotes/KingJohnOfEngland's defeat was used by the Barons as a motivation for forcing him to sign the Magna Carta.
* The Battle of Hattin 1187 to the Kingdom of Jerusalem, which wiped out almost the whole army of the kingdom. It led to the downfall of Jerusalem itself. Never again were the Franks on offensive at Outremer anymore after the defeat at Hattin.
* The Mongols have done this a lot to others: they conquered China, decimated Persia, ravaged Russia, and nearly conquered Europe. For Russians especially, the Mongol attack on UsefulNotes/KievanRus is cited as one of the major reasons for why Russians are backward compared to Europe. Other historians see this as classic Russian self-pity significantly exaggerating the impact and destruction (which was quite huge) out of all proportion to better justify xenophobia.
* The UsefulNotes/ByzantineEmpire periodically came BackFromTheBrink after major defeats and setbacks, until of course they stopped doing that in the 1450s. One especially famous one was the Battle of Manzikert in 1071, when the Seljuk Turks routed the much larger Roman army and captured Emperor Romanos IV Diogenes. While modern scholars don't consider it a "turning point" anymore, the disaster at Manzikert led to the loss of most of Anatolia (some parts of which irrevocably) and plunging the Empire into a series of civil wars. Until the end of the Empire in 1453 Manzikert was widely known as "that day" and considered one of the most shameful days of the Eastern Roman Empire. The other is the Fourth Crusade but that isn't considered a defeat so much as appalling and disgusting treachery and sneak attacks on the part of the Latins and Venetian Crusaders (albeit inspired by their own anti-Latin and anti-Venetian policies).


[[folder: Renaissance Era ]]

* The Loire Campaign in UsefulNotes/TheHundredYearsWar. Before it, everyone knew that English conquest of France was just a question of time, and the imminent conquest of Orléans would speed up things. Then the French, their courage restored by JoanOfArc, lifted the siege, launched the campaign and inflicted the English a series of defeats, the final of which, the Battle of Patay, being a CurbStompBattle that ''crippled the English army for the rest of the war''. Indeed, a major bone for contention in the UsefulNotes/WarsOfTheRoses and well in the early years of UsefulNotes/TheHouseOfTudor was "Who lost France?" and when are they going to get their Angevin territories back. It wasn't until UsefulNotes/TheFrenchRevolution, where the English decided they hated democracy more than the French King that they realized they should stop asserting their claim on the latter's crown, that they got out of TheRemnant of that revanchism.
* The Battle of Lepanto and the Siege of Vienna of 1682 for the Ottoman Empire: the near complete destruction of their fleet and the loss of all their experienced crews at Lepanto signaled the end of the Ottoman supremacy over the Mediterranean (the fleet was quickly rebuilt in terms of ships, but the crews weren't even half as competent as their predecessors, and the Ottoman fleet never recovered), and the defeat at Vienna marked the end of the Ottoman expansion in Europe.
* The Battle of Ksar El Kebir in 1578 was this for the Portuguese Empire. With the empire already becoming stagnant, a massive fortune was then spent in amassing one of the largest and most well equiped land armies in Europe at the time, in an attempt by the young Portuguese king to expand their holdings in North Africa. However, they were met by the Moors and their Ottoman allies, who vastly outnumbered them. The Portuguese army fought valiantly, but was utterly crushed, the king missing or dead, and thousands of noblemen made prisoner. Another vast fortune was spent ransoming them back, and, since the king had disappeared without producing an heir, shortly after the country was taken over by the Spanish in a Personal Union, which lasted for sixty years, during which Portugal could only watch as they further lost a great amount of power, colonies, and influence. By the time they got their independence back, the other nations of Europe, with their superior economies and manpower, were well underway in their own discovery and colonisation efforts, and for Portugal there was no going back to their former glory.
* The Deluge is this for the UsefulNotes/PolishLithuanianCommonwealth. The Swedish Kingdoms unleashed a level of destruction there comparable to the UsefulNotes/ThirtyYearsWar, and completely destroyed 188 cities and towns, 81 castles, and 136 churches in Poland, and leading to the loss of 1/3rds of its population, the utter destruction of Warsaw and the permanent loss of several Polish cultural artworks. Moreoever, it was the end of Poland's status as the superpower of Eastern Europe, giving way to Sweden briefly. And a hundred years later, the Kingdom would be erased from the map.

* The defeat and death of UsefulNotes/CarolusRex in UsefulNotes/TheGreatNorthernWar was this for Sweden and others who keep lamenting ForWantOfANail had he not died. This was also the end of Sweden as a great power in Central-Eastern Europe, while it marked the rise of UsefulNotes/{{Russia}} under UsefulNotes/PeterTheGreat as the hegemon of Eastern Europe (a position it enjoys to this day).
* The Battle of Quiberon Bay during the UsefulNotes/SevenYearsWar effectively bankrupted the French government by causing a credit crunch (because financiers realized that the British could strike French trade at will). They ''still'' hadn't paid the debts off by the time of the Revolution, nearly fifty years later.
* For the Scottish and the Jacobites, the Battle of Culloden was this. It was the biggest and largest Jacobite Rebellion with the largest ghost of a chance and the defeat led to a brutal campaign by the English in the Highlands.
* The Mughal Empire never recovered from Nader Shah's invasion of India in the 1730s-1740s. It culminated in the sack of Delhi which led to the Persians stealing the Peacock Throne of the Emperor and the famous Koh-I-Noor diamond (which would pass to the Afghanis than the Sikh Empire of Raja Ranjitsingh and then the English who keep it even today to much gritting of teeth). Other defeats, like the Maratha Confederacy's loss at the Third Battle of Panipat, the 1757 Battle of Plassey which the East India Company won and defeated the Nawab of Bengal endure as marks of bitterness among Indians about the failure of local rulers to effectively mount a challenge against the English.

* During UsefulNotes/TheNapoleonicWars:
** The Battle of Jena-Auerstädt. The Prussian army had been considered the finest in Europe ever since the wars of UsefulNotes/FrederickTheGreat, its soldiers inculcated with 'corpse discipline'-should they be shot and killed, their corpse should continue to march, load, and fire regardless. While Napoleon pounced with his main force on a Prussian detachment at Jena, the Iron Marshal Davout threw back the Prussian main army with a single corps. The Prussian army had been shattered in a matter of hours, and the pursuit destroyed it and the Prussian state with it. In the wake of this defeat, Prussia was forced to accept the loss of half its population and restrictions on its military. The defeat was so extreme, the Prussians basically rebuilt their society to recover and defeat the French. In the military, the corporal punishment necessary for 'corpse discipline' was abolished, and the concept of a citizen army was embraced. The Prussians adopted the first modern general staff, allowing non-aristocrats to become professional staff officers. They even went so far as to abolish serfdom to make a society that could defeat Napoleon.
** The Battle of Trafalgar became this for the Combined Navies in the Napoleonic Wars - the French and Spanish lost almost seven times as men as the British, and the majority of their active ships-of-the-line. Not only would they never challenge the British at sea again, it gave the British the ability to strike at will at French and Spanish trade, contributing directly to the collapse of both empires by slowly throttling their treasuries. Indeed, when Napoleon was presented with an embroidery of an Eagle strangling a Lion, he said that it should be the other way round. During the battle itself, the explosion of the ''Achille'' was what signaled the end of the engagement and convinced the Franco-Spanish fleet to ru n.
** The Battle of Bailén - the Spanish destroyed three French divisions. Unfortunately, it was so shocking...that Napoleon turned up to sort the mess out in person, and promptly sent Spain into retreat. Even then, although Napoleon sent the Spanish into retreat, it was the first clear defeat of a major French army since he came to power, which (along with the defense of Saragossa) encouraged his enemies to continue their fight. Thus not only did the French army find itself stuck in a bloody war on the Iberian Peninsula for the next six years, but Austria started another war in the following year (1809), leading to the first defeat of an Army led by Napoleon in person at Aspern.
** Napoleon's invasion of Russia followed by the Battle of Leipzig led L'Empereur to AbdicateTheThrone, which thanks to Bourbon incompetence led to The Hundred Days, which ended with Waterloo. As with many battles, what gave Waterloo such a "knock-out blow" mystique was not the battle itself but the subsequent pursuit. Thus in 1815, unlike 1812/13 and 1813/14, Napoleon's army was not given time to regroup and replenish. Waterloo led to France being occupied by the Congress Powers for five years (the longest until World War II) and it would be the end of the Anglo-French Rivalry, decisively in favor of the English.
* The entire First Opium War was this to UsefulNotes/{{China}}. China's capitulation and the total lack of ''any'' CurbStompCushion in sight humbled the Chinese and marked the beginning of a era of being forced to negotiate from a position of weakness, and ending China's belief that it was the Middle Kingdom without a peer, with total hegemony over other nations. They even came up with the term [[https://en.wikipedia.org/wiki/Unequal_treaty Unequal Treaty]] to describe the treaties that resulted from these losses. Even in contemporary China, it's still invoked with anger as is the Six-Nation Army's sack and looting of China in the Boxer Rebellion and the defeat to Japan in the First Sino Japanese War.
* The Battle of the Alamo, which was a major defeat for the Republic of Texas. Subverted and completely reversed in that the Alamo actually [[{{DefensiveFeintTrap}} fulfilled its objectives.]] While a tactical defeat, it was a resounding strategic victory that not only severely bled out the Mexican Army and allowed the Texan Army to organize into a fighting force, but also provided substantial [[{{RememberTheAlamo}} morale boost.]] The men of the Alamo had actually been ordered by Sam Houston to leave--Bowie's men originally came to destroy the fort, but the defenders chose to stay. Perhaps a better example from that war is the Battle of San Jacinto, where the relatively ragtag and much smaller Texan army hid out in the swamplands near what is now Houston, and defeated Santa Anna's men in a completely unexpected attack.
* While the Battle of Gettysburg is popularly considered the turning point of the AmericanCivilWar , many however actually see the Battle of Antietam as the real turning point of the war, because this was the last real chance the Confederacy had of not just temporarily carrying the war north (there was also a Southern offensive in the west at the time, while even if Gettysburg had been won by Lee, Vicksburg still would have fallen to Grant), but also to gain recognition from the major European powers. Gettysburg had essentially no impact on the long term reputation of Lee and his army; the Northern public and the South alike considered him undefeated when Grant began his offensive in 1864.
** Even after Gettysburg, the South still had one last chance to win, or at the very least, get a negotiated peace that would leave the Confederacy intact. That would be by keeping Union forces stalemated in sieges until November 1864, when the Northern public, sick of a long, bloody war with no end in sight, would vote Lincoln out of office and elect George [=McClellan=] President, who was campaigning on a Peace platform. In the east, Grant's forces were held at bay at Petersburg while in the west, Sherman's forces were tied up in the siege of Atlanta. But Atlanta fell to Sherman's forces in early September, boosting Northern morale and resulting in Lincoln getting re-elected. When Atlanta fell, everyone knew the South had truly lost.
** The fall of Petersburg caused the Confederacy to realize that their capital of Richmond would soon fall as well, which eventually lead the engagement at the Appomattox Court House and General Lee's surrender to Grant.
* For Tsarist Russia, the UsefulNotes/CrimeanWar was this. It proved how backward Russia was from England and France and while that war was famed for incompetence on all sides and created many reforms in the armies of Western Europe, in Russia, it finally convinced the autocratic Empire to *gasp* abolish serfdom and tentatively go on the path to liberal reforms.
* The UsefulNotes/FrancoPrussianWar is what named the concept of revanchism. The Prussians victory, their capture of Head-of-State Napoleon III and them using the Palais de Versailles for the founding of UsefulNotes/ImperialGermany alongside the taking of territories of Alsace and Lorraine created kvetching like you can't believe. School-children were taught geography about missing territories and how when they [[MexicoCalledTheyWantTexasBack grow up they are going to get it back]]. It also led to the Paris Commune which was brutally suppressed and more or less ended monarchism in France with even conservatives agreeing to be a Republic. It was the permanent end of France in favor of Germany as Continental Europe's great power.


[[folder: Early 20th Century ]]

* The disasters that were the Battles of Mukden and Tsushima were largely responsible for the Tsarist government to fold the UsefulNotes/RussoJapaneseWar, despite the still enormous strategic advantage and intelligence reporting of the impending collapse of the Japanese economy. The sense of national shame still felt forty years later was one of the major reasons the Soviet Union agreed to join the war against Japan in the closing days of WWII, despite technically still being neutral[[note]]The details of the non-aggression pact between the Soviet Union and Empire of Japan said that it would lose power only a year after its denonsation or non-prolongation, which happened in the Spring of '45[[/note]].


[[folder: World War I ]]

* Gallipolli for Australia and New Zealand. It's viewed in much the vein as Dunkirk for the UK, only more so.
* During the [[RedOctober Russian Civil War]], Kolchak's defeat at Tobol was the turning point for the Whites to start losing. After that defeat, Kolchak's Eastern White army started a retreat that quickly escalated to panicked flight resulting in the fall of Omsk, the rebellion at Irkutsk and Admiral Kolchak's own demise. For Denikin's Southern White army, the failure of his Moscow offensive at the battle of Orel was such a defeat; after Tobol and Orel the Reds had a practically guaranteed win, and the rest of the war was basically cleanup of remnant Whites, Blacks and Greens.
* The sinking of the SMS ''Szent István'' during UsefulNotes/WorldWarI was this for the Austro-Hungarian Navy. Before that, the Austro-Hungarians had tried various times to break the Otranto Barrage. Then the ''Szent István'', the ''flagship'' of the fleet, was sunk by ''two Italian torpedo boats that just happened to be in the area'', and not only the attack the flagship was supposed to lead was canceled, but the Austro-Hungarian navy didn't dare to leave the ports anymore.
** Not that there was much time left for another attempt - the ''Szent István'' was sunk on 10 June 1918, less than five months before the land battle of Vittorio Veneto which forced Austria-Hungary to sue for peace.
* {{Subverted}} by the Battle of Caporetto of UsefulNotes/WorldWarOne. While 'Caporetto' is ''still'' synonymous with 'complete and utter defeat' in Italian and the Italian Army was forced to cede half of Veneto to the Austro-Hungarian invasion, the Italian soldiers, upon noticing the civilians were running from the invaders, [[HeroicSecondWind rallied up at the Piave river and stopped any attempt to pass it for a year]]. One year later, the Battle of Vittorio Veneto was one for the Austro-Hungarians: while the Austro-Hungarian Army quickly recovered from being ''dissolved'' (as pretty much all fighting units had been dispersed and routed, but managed to reassemble fairly fast), the Austro-Hungarian Empire did not, and collapsed three days before the end of the battle (and two after begging for an armistice). Furthermore, the terms of the armistice (that included free passage to Germany through Austria) forced the German Empire to ask for armistice, as the plan to fight through the winter to get favourable peace conditions had been shot to hell by the threat of a million battle-hardened soldiers from the South.


[[folder: World War II ]]

* The [[http://en.wikipedia.org/wiki/Battle_of_Midway Battle of Midway]] became this for the Japanese, as their loss in the battle effectively halted their expansion and put them fully on the defensive for the first time. US Naval Supremacy was only a matter of time, however; the Empire couldn't stay lucky forever in the face of the Allies' overwhelming economic and industrial superiority.
** In a sense, the Doolittle Raid counts as well. After Pearl, the Japanese appeared invincible, seizing island after island and colony after colony. By April 1942, they had all but swept the Allies from the Pacific. Then, sixteen B-25s were transported by carrier a few hundred miles from Japan and dropped light bombs on Japanese cities. Almost no infrastructure damage was inflicted, but it scared the crap out of the Japanese. This drove Admiral Yamamoto to fight much more aggressively, causing him to attack Midway in order to secure it and thus the Japanese defense perimeter would be complete. Then, at Midway, all four of Yamamoto's carriers were sunk...
** The raid also had a vital strategic effect. Japan's home defense fleet was very weak, so they recalled a fleet that was heading for the Indian Ocean. This gave the Royal Navy a much-needed breather to regroup and regain its strength in the Pacific.
* The Battle of the Philippine Sea, in 1944, became another one for Japan. After two years, they had finally rebuilt their carrier forces, brought their newest and most advanced carrier--the armored carrier Taiho--into play, they had a huge advantage in position, geography, and circumstances (a strong wind that would considerably bolster Japanese carrier attack ranges while reducing the Americans', air bases closer to the enemy to field additional and heavier aircraft as well as land carrier aircraft returning from an extreme range attack on the enemey, etc), and the Americans were in the middle of invading islands that would give America airbases within strategic bombing range of the Japanese home islands. They sent out attack wave after attack wave, considerably more aircraft than they had had at their disposal at Midway, and the wind advantage meant that they were seemingly beyond the range of American reprisal. Only for the Japanese to find out that their pilots, planes, doctrine, technology, and ships were ''horribly'' outmatched when the American forces absolutely annihilated wave after wave of Japanese aircraft (this coming to be known as "the Great Marianas Turkey Shoot"), with only minor damage on a battleship to show for it. Then American submarines sank two of their best fleet carriers--including the brand-new and pride-of-the-fleet Taiho, and the American counterattack still managed to catch up to and sink one more fleet carrier. The battle completely dashed any hope of the Japanese Navy turning the war around.
* The Battle of Leyte Gulf, following the Battle of the Philippine Sea, was the Imperial Japanese Navy's final attempt to stop the US Navy. With its carrier forces utterly decimated and reduced to being nothing more than a decoy, the IJN sortied the vast majority of its remaining fleet. The Southern Force was summarily obliterated by a perfectly orchestrated night-time ambush, with a Japanese battleship being effectively executed by a firing line composed largely of the American battleships that had been sunk at Pearl Harbor (and then raised and repaired). The Northern Force, comprised of the decoy (as in, largely empty) carriers were all sunk by overwhelming carrier attack. The Center Force, where all of the true strength lay, received a golden opportunity after Halsey chased after the decoy force without so much as leaving a picket ship in the strait leading to his landing forces and escort carriers, stumbling upon Taffy 3: half a dozen slow, unarmored escort carriers and a few destroyers[[note]]A single ship in Center Force, the battleship Yamato, was ''larger and better-armed than all of Taffy 3 combined''.[[/note]] that were in the middle of supporting landing operations and were completely astonished by Center Force's arrival. Cue the most mis-matched naval battle in history, with Taffy 3 actually fighting off one of the most powerful surface action groups ever assembled with nothing more than a few tin-can destroyers, planes armed with just machine guns and light bombs, and audacious, desperate courage. By the end, the Northern Force was decimated, the Southern Force was annihilated, and the Center Force had taken severe losses, with only one escort carrier, two destroyers, and one destroyer escorts sunk to show for it. The Japanese Navy was destroyed as a significant fighting force, its remnants scattering to various locations and being hunted down in detail by the US Navy.
* Britain's 1940 retreat from Dunkirk marked a turning point in UsefulNotes/WorldWarII, but is remembered in Britain more for the heroic rescue of stranded troops than as a defeat.
** The "Fall of France" fits the trope name better. Dunkirk is more of snatching victory from the jaws of defeat (although Churchill was quick to point out that you don't win wars with retreats and that while it was great to save the troops, the Fall of France was still a major defeat for the Allies). France had been the major balancing power on the continent against a resurgent Germany; everyone, from the French to the British to the Russians to the German General Staff believed it would be a long and brutal slugging match. When, according to von Manstein's plan, Guderian's XIX Panzer Corps cracked through the thin French defenses at Sedan, there was nothing between the Germans and the Channel, and the grand strategic balance of the war had been destroyed at a stroke. The most powerful army in Europe had been neutralized and their country overrun in six weeks.
*** Also, they had to leave most of their heavy arms, fuel, ammunition, vehicles, and equipment behind (which was enough to supply eight to ten divisions), so it would take a while before they were in a condition to face the Wehrmacht in the field again. Granted, much of the equipment was old or obsolescent, but they still had to rebuild from the ground up.
* The failed Rzhev offensive and loss of Sevastopol of 1942 were probably this for the Soviet Union. They were later overshadowed by the great victories of Stalingrad and Kursk, but these failures, which stemmed largely from overconfidence after the successful Battle of Moscow and generally crappy Soviet logistics, costed enormously both in lives and materiel, and later weighed heavily over Soviet morals and military thinking even late in the war and after it.
* For the European colonial powers in general, and the UK in particular, the [[http://www.historylearningsite.co.uk/fall_of_singapore.htm Fall of Singapore]]. It had been boasted that Singapore was the best-defended city in the world, the armour-piercing shells of her heavy gun emplacements capable of punching through any ship the Japanese had to offer. However, Singapore was besieged from the landward side, and their anti-battleship defenses were wholly ineffective at targeting infantry. Percival had 100,000 troops on paper, but they were in no shape to continue fighting. Realising that their situation was hopeless, he surrendered. Only to find that the Japanese only numbered some 30,000 and their supply situation had been even worse. It was this event (among others in Southeast Asia) that inspired the acceleration of the decolonisation process - the European colonists were not, and never had been invincible.
** Churchill himself felt the fall of Singapore to the Japanese in 1942 was the greatest defeat in British history.
-->'''Winston Churchill''':''"I put the telephone down. I was thankful to be alone. In all the war I never received a more direct shock."''
** It's generally acknowledged that even had Percival pushed the issue, he felt that PyrrhicVictory would not have been worth it.
* The [[http://en.wikipedia.org/wiki/Battle_of_Stalingrad Battle of Stalingrad]], for the German forces in the Soviet Union. The Sixth Army was one of the largest German field armies, and the battle became an intense clash of ideologies: Nazism vs communism, Hitler vs Stalin. When the army was cut off, the Nazis immediately put a lid on all media reports regarding Stalingrad. Finally, the last remnants of the Sixth Army surrendered in February 1943. Nearly 100,000 Germans were captured, out of an initial force of 250,000. The scale of the catastrophe was so great that even Goebbels could not camouflage the defeat as he had the numerous other setbacks on the Eastern Front. It was the first time that the Nazis publicly acknowledged a failure in the war effort, causing German civilians to begin doubting their promise of final victory.
* The [[http://en.wikipedia.org/wiki/Second_Battle_of_El_Alamein Second Battle of El Alamein]], for the Axis forces in North Africa.
** Despite the loss and withdrawal from El Alamein, the campaign in North Africa continued for another six months. When Rommel ordered the retreat, Montgomery did not pursue and thus allowed the broken German formations to withdraw, fortifying themselves within Tunisia. The loss of Tunisia occurred only a few months after the loss at Stalingrad, with a quarter of a million troops taken prisoner. Soon after, the loss of Sicily was so great that the Italians overthrew Mussolini.
** Rommel probably thought he could regroup and attack again the following year after halting the British offensive. What made El Alamein ensure this would never happen was that not too long after, the Americans started landing in Morocco and Algeria.
** After failing to break through to Alexandria and beyond in the ''First'' battle of El Alamein, Rommel would have had to retreat after the American landing in Morocco and Algeria in any case. Some people therefore see the Second Battle of El Alamein as having been fought to a large extent to build up British morale and prestige in a last chance to win a major battle without the American army helping...
* The Night of Taranto during UsefulNotes/WorldWarII. Before it, the mere ''threat'' of the Italian battlefleet stationed at Taranto was making the Royal Navy cower. After a carrier attack ''neutralized half of the Italian battleships'' (including the newly completed ''Littorio'', [[SuperPrototype the most powerful battleship in Europe]], damaged and neutralized for five months), the balance of power was firmly into British hands, and the Italians never managed to win a decisive engagement.
** Incredibly and unbelievably {{Subverted}} in the Italian revenge for that, the Raid on Alexandria, in which six frogmen with three manned torpedoes penetrated Alexandria's harbour and sank two battleships and damaged a tanker (plus a destroyer by accident: it was too close to the tanker when the mine placed on it by the frogmen exploded). In theory the Mediterranean Fleet had been neutralized, and the Italians were free to dominate the Mediterranean Sea until the battleships could be repaired or replaced... Except the Italian high command ''failed to find out'': the frogmen had been all captured before they could report their success, and the British immediately raised the battleships (sank in shallow waters) and patched them up enough that air recon believed they had not been damaged. While the raid ''did'' mark the start of six months of Axis victories in the Mediterranean, had the Italians knew of it nobody knows what they would have done.
* For the U-Boat Service, May 1943 became known as "Black May" when 41 submarines, a full quarter of the operational U-boat fleet, were destroyed. While the "Happy Times" had long since passed, and the British no longer made the same mistakes, this marked the decisive shift in the Battle of the Atlantic. The industrial and intellectual powerhouse of the United States was brought into full force, with ships being built faster than they could be sunk and U-boats being sunk faster than they could be built. All remaining U-boats retreated to their bases in France, and the Kriegsmarine immediately began outfitting all boats with the latest technology to improve operations. However, the loss of so many experienced crews already deeply impacted the force's morale, with crews wondering why they bothered venturing out anymore. Even flotilla commanders started to tell departing boats "Never mind sinking ships. Just come back, please."
* The summer of 1944 effectively sealed Germany's defeat. First came the D-Day invasions, when American, British, and Canadian troops landed on the coast of Normandy. The short-sighted micromanagement of the German Army by Hitler caused vital Panzer divisions to not be moved to the battle, allowing the Allies to establish a firm beachhead that soon became impossible to dislodge. A few weeks later, the Soviets launched Operation Bagration, which smashed the Wehrmacht's Army Group Center in Poland and wiped out divisions that Germany could no longer replace. These simultaneous battles shattered German morale, leading them to realize that defeat was inevitable.


[[folder: Vietnam War ]]

* In the prelude to the US involvement in Southeast Asia, the French attempted to reclaim control of their colonies in the area after WorldWarTwo ended. Unfortunately their [[CurbStompBattle shockingly fast defeat]] against Germany early in the war shattered the illusion that the French military was invincible, and emboldened Ho Chi Minh's resolve to kick them out of Vietnam as well. Though the French managed to remain in control for a few years, their defeat at the [[http://en.wikipedia.org/wiki/Battle_of_Dien_Bien_Phu Battle of Dien Bien Phu]] marked the end of French control of the region. For the French military, it was such a major blow after UsefulNotes/WorldWarII, that they overcompensated in the Algerian crisis and resorted to extra-brutal measures to prove they, a major European great power, won't suffer defeat from weak nations again.
* [[TheVietnamWar Vietnam]] was the greatest military quagmire in United States history.
** Within the war itself, the Tet Offensive can be considered this. The Vietcong attacked many cities simultaneously, notably claiming the US Embassy in Saigon. This was a major hit to the vision of American strength and hit their morale deeply, especially as nightly TV news had shown repeated US victories over the Vietcong militarily speaking. In reality, the Vietcong suffered heavier losses than the American troops and the attack itself devastated the Vietcong's ability to operate to such an extent the North Vietnamese Army took over operations in South Vietnam, but in terms of perception this drastically swayed the war in their favour.
*** It was one of a few times when a major victory for a country (the US) was treated as a defeat. The fact that the US had beaten the Vietnamese very, very badly during the Tet Offensive was secondary to the fact that the unpopular war was still going on and that the offensive convinced Americans that the war would continue for years at that point. The media did the military no favors in its reporting on the war, and this reporting helped to shape US public opinion. The lesson was not lost on the military, and all US wars since then have had considerably tighter control over what reporters can show.


[[folder: Other Wars ]]

* The Six-Day War was this for the Arab world. Not only had several invading armies been beaten by the Israelis, but Israel ended up in control of eastern Jerusalem (with the holy sites sacred to all the Abrahamic religions) and the Sinai Peninsula. The fact that a small, outnumbered, and surrounded country could do this was considered a disaster by the Arabs. However, in the 1973 war, the Arabs (especially Egypt) gave a better account of themselves; while the Israelis managed to maneuver themselves into superior positions during the late stages, it could no longer inflict another catasphohe as the Six-Day War on their enemies, lessening the legacy of that defeat.
* The 2003 Iraq War had a similar effect to Vietnam: America easily won militarily, but the task of rebuilding the country led to a long occupation with mounting casualties.

[[folder: Sports ]]

* The 2004 Dream Team during the 2004 OlympicGames, who were soundly beaten by... ''Puerto Rico'' and ''Lithuania'' (the latter of whom came close to beating the squad 4 years prior!). And then, worse yet, were trumpled in the semifinals to Argentina, breaking a streak of three straight gold medals with NBA players. The media refused to let American basketball players forget, until they got it together for the Redeem Team run in 2008.
* The New England Patriots are best remembered for their 18-1 season in 2007. They were undefeated heading into the Super Bowl, and they lost the game to the underdog New York Giants on a flukey catch.
** New Yorkers proudly dubbed this season as "18 wins and one ''GIANT'' loss!"
* The UsefulNotes/{{Miami}} Heat, led by [=LeBron=] James, Dwyane Wade and Chris Bosh, ran roughshod through the Eastern Conference in the 2011 playoffs, defeating even the Boston Celtics and the Chicago Bulls in five games apiece. Entering the Finals against Dallas, the Heat led the series 2-1... before losing the next three games to the Mavericks. It especially stings when you consider [=LeBron=] saying that he'd win multiple championships with Wade and Bosh. The media, the fans ''and'' the internet never let the Heat live it down after that, and the loss was haunting enough that it sent [=LeBron=] past the DespairEventHorizon. (he lead the Heat to the title the following year [[TheAce winning basically every award in the process]], but the legacy remains because he left UsefulNotes/{{Cleveland}} solely to finally get a title, only to fail again with a better team)
** It didn't help that the Heat seemed on the cusp of seizing victory for the series in both Game 2 (which would have severely crippled Dallas' morale) and Game 4, only for Lebron to get a little presumptuous by celebrating with Wade next to the Dallas bench in Game 2, leading to the miracle comeback that was led by Dallas superstar Dirk Nowitzki. From there, the Finals were a hard-fought battle to the finish.
* Speaking of UsefulNotes/{{Cleveland}}, their teams have plenty of this, helped by the fact that most of their notable defeats can be summed up with a single phrase (The Shot, The Fumble, The Drive, Red Right 88, The Slip). Two were even off-field: The Move, where the Browns were moved overnight to Baltimore (to add insult to injury, the renamed Baltimore Ravens would win their first Super Bowl just 5 years later, a victory that Browns fans still believe should rightfully have been thiers); and The Decision, where [=LeBron=] announced his departure.
* TheWorldCup has at least three finals, 1950 (Brazil loses to Uruguay at home; 5 titles later, it's still a sore point), 1954 (DarkHorseVictory of Germany over the heavily-favored Hungary) and 1974 (DarkHorseVictory of Germany over the heavily-favored Netherlands... though not as unexpected as the previous one).
** Previously, both the previous World Cup's champion and the host country of the upcoming World Cup were given automatic spots in the upcoming World Cup. Then France, winners of the 1998 World Cup, turned in an atrocious performance in 2002, earning only one draw in three group games and failing to score a single goal. Since 2006, only the host country gets a free pass.
** In 2014, Brazil is the host nation, their first home tournament since their 1950 defeat (itself already a ShockingDefeatLegacy). With their new superstar in Neymar, Brazil was the heavy favorites for the World Cup - although it was nip and tuck a lot of the way. They made it to the semifinals, but they had lost Neymar to injury, forcing him to miss the rest of the tournament. As a result, Brazil gets utterly humiliated by Germany with a score of '''7-1 in front of their own native fans''', which is both Germany's greatest margin of victory ''and'' Brazil's greatest margin of defeat, as well as one of the most lopsided games in World Cup history. While Germany would go on to win the final against Argentina, Brazil would have to settle for a third place match against the Dutch... only to lose yet again 0-3. This will ''not'' ever leave Brazil's consciousness for quite some time. To the point it reached MemeticMutation, with subsequent bad performances of the national team (or the country itself) having Brazilians react with "Germany goal!" and "7-1 wasn't enough!".
* The UsefulNotes/{{Boston}} Red Sox emassed [[http://en.wikipedia.org/wiki/Curse_of_the_Bambino#.22Cursed.22_results quite some]] in their 86 year drought. The Chicago Cubs's [[http://www.billygoattavern.com/legend/curse/ one also deserves mention]].
** Now that the Cubs have ''finally'' won their first series in 108 years, the title for longest drought in baseball now goes to the Cleveland Indians, who lost the title against the Cubs.
* For most of TheEighties and the first half of TheNineties the New York Yankees were in a DorkAge (relatively speaking for a franchise now with 27 World Series championships), having not made the postseason between 1982 and 1993[[note]]they most likely would have made it in 1994 with a 6 1/2 game lead in the AL East had the players' strike not cancelled the last few weeks of the season[[/note]]. In the '95 season they made it as the AL Wild Card and seized a 2-0 lead in the best-of-5 series against the Seattle Mariners before dropping Games 3, 4, and 5 at the Kingdome, the latter on a 2-run double in the bottom of the 11th inning. With a tempermental owner in George Steinbrenner, the Yankees brought about large changes to the starting roster both from within (promoting Derek Jeter and Mariano Rivera up to the starting lineup) and without (trading for, among others, Tino Martinez, who was a member of those '95 Mariners), as well as firing manager Buck Showalter and replacing him with Joe Torre. With a new core in place, the Yankees would win four of the next five World Series.
* [[Creator/TheSportsGuy Bill Simmons]] wrote a couple of articles about the [[http://proxy.espn.go.com/espn/page2/story?page=simmons/020528 Levels of]] [[http://sports.espn.go.com/espn/page2/story?page=simmons/071001 Losing]] (first article from 2002, second one from 2007 following the New York Mets' September collapse in the NL East), with Level 1 being reserved as the sole domain of "That Game" (Game 6 of the 1986 World Series). Then the [[http://sports.espn.go.com/espn/page2/story?page=simmons/100129&sportCat=nfl Brett Favre-led Minnesota Vikings choked away the 2010 NFC Championship Game to the New Orleans Saints]] (the batch of emails in the article conveys quite nicely the devastation on Vikings fans' psyche), and Simmons went back and made a list of tortured teams eligible for a loss of that magnitude.[[note]]Note that in the years since the article was published the Seattle Seahawks, San Francisco Giants, Cleveland Cavaliers, and Chicago Cubs have won championships and so would no longer be eligible by his criteria.[[/note]]
* During the early 90s, the Buffalo Bills were the best AFC football team in the NFL and went to four straight Super Bowls, only to lose them all. But it's the first SuperBowl loss that people remember the most. Buffalo had their full arsenal with Jim Kelly, one of the best quarterbacks of the 90s leading his team. Their opponents, the New York Giants, were a weaker team on paper and they were led by their backup quarterback, Jeff Hostetler, who was at the end of his long career. What should have been a sure win for the Buffalo Bills, turned out to be a close, competitive game that ended in one of the most unforgettable, heartbreaking, field goal kick misses in NFL history, known as "Wide Right".
