->''"In 1936 it was clear to everyone that if Britain would only help the Spanish Government, even to the extent of a few million pounds' worth of arms, Franco would collapse and German strategy would be severely dislocated... Yet in the most mean, cowardly, hypocritical way the British ruling class did everything they could to hand Spain over to Franco and the Nazis."''
-->-- '''Creator/GeorgeOrwell''', ''Looking Back on the [[UsefulNotes/SpanishCivilWar Spanish War]]''

Our heroes are in trouble. They're being completely slaughtered by the BigBad's [[{{Mooks}} forces]], who are obviously too strong for them... but wait! There is a large regiment of [[TheCavalry cavalry]] in the area. Let's just [[GondorCallsForAid call in]] these guys and the Big Bad will be easily defeated.

Or so you'd think. In fact, the cavalry don't feel like rushing in to save the day at all, and stubbornly refuse your desperate call for help. Perhaps they have some kind of ObstructiveCodeOfConduct forbidding them to intervene. Perhaps the BigBad has powerful friends whom they don't want to get into trouble with. Or the Cavalry are organised more or less democratically and [[DividedWeFall some of them are opposed to helping the heroes]] (or they all agree about ''that'', but argue endlessly about the details). Whatever the reason, the Cavalry refuses.

This trope is in play when the heroes need help, and there is an entity which could and/or should provide it but says 'Screw you'. Can lead to the heroes (and, if the unwilling Cavalry's excuse is particularly poor, the audience) exclaiming 'Why don't you do something?' or [[WhatTheHellHero 'What The Hell, Hero?']] If the heroes looked up to their supposed protectors, this will result in a BrokenPedestal.

Comes in two varieties:
* '''Formal Authority''' is when the unwilling Cavalry is a (supposedly) neutral authority figure with power over both the heroes and the villains. They don't rush in to protect the heroes, even if the villain is clearly violating the rules which they are supposed to enforce - for example, in a schoolyard setting, a teacher not doing anything to protect the bullied protagonist. Related to AdultsAreUseless and PoliceAreUseless.
* '''No Formal Authority''' is when the Cavalry have no formal power over the villains, but are big and strong enough to significantly aid the heroes. They are supposed to be on the heroes' side (thus making them potential Cavalry), but refuse to help.

Compare CavalryBetrayal (when the Cavalry does show up, but turns out not to be on the heroes' side after all). Contrast OneManArmy (when the hero refuses any help from the Cavalry and does all the jobs on his own).


!!Formal Authority


[[folder:Anime & Manga]]
* In ''Anime/LastExile'', the Guild (an organisation supposed to enforce [[UsefulNotes/TheLawsAndCustomsOfWar The Laws And Customs Of War]]) does nothing to help an army which is being attacked with "forbidden" tactics, because they favour the offending army.
* ''Manga/{{Berserk}}'': Casca's first meeting with Griffith starts with her escaping from a rapist. Instead of helping her, he throws a sword between the two. After a struggle, Casca wins, and Griffith allows her to join him.

[[folder:Real Life]]
* It's hard to keep count of the times the UsefulNotes/UnitedNations have refused the Cavalry call (largely by [[WouldBeRudeToSayGenocide calling "Genocide" a "Civil War"]]), due to the decision-making process which allows several powerful nations, whose interests are often diametrically opposed, a veto.
** The General Assembly attempted to LoopholeAbuse their way around this deadlock of the Security Council through enacting Resolution 377(A), i.e. "Uniting for Peace". It's only worked once in a while.
* The UsefulNotes/UnitedNations' predecessor, the League of Nations, wasn't exactly eager Cavalry, either - they stood and watched while the Japanese invaded (Chinese) Manchuria, the Italians brutally conquered Abyssinia and a handful of Spanish generals staged a coup against their government which led to the UsefulNotes/SpanishCivilWar.

!!No Formal Authority

[[folder:Films -- Live-Action]]
* In ''Film/{{Zulu}}'', a force of actual cavalry arrives upon the scene where the heroes are making a LastStand... and promptly flees. This happened in RealLife, too, but in reality, the cavalry were much more [[JustifiedTrope justified]] in their flight than depicted in the film.
* Thranduil in ''Film/TheHobbit'' is shown in flashbacks to have refused to help the dwarves, both against Smaug in Erebor and against the orcs in Moria, choosing not to lead his people into a hopeless battle against an enemy that they have no chance of defeating. The White Council (minus Gandalf) were going to be a third one but [[spoiler:the dwarves (with good reason) left before they could refuse to help them.]]
* In ''Film/MulanRiseOfAWarrior'', Mulan's DefensiveFeintTrap fails due to this.
* In ''Film/TheDarkKnightRises'', when Bane has all of Gotham held hostage, despite [[BlatantLies the government saying that they won't give up on the city]], Gordon knows that they're on their own.
* In ''Film/TheLastJedi'', the plan for the Resistance is to get to an old Rebel base and wait for the First Order to pass, while sending out a distress signal to their allies across the Outer Rim to get help. [[spoiler:However, since the First Order is so powerful, and with the New Republic apparently helpless after the destruction of the Senate and most of their fleet in ''TheForceAwakens'', no one comes.]]

[[folder:Live-Action TV]]
* ''Series/GameOfThrones'': Lysa Arryn refuses to lend her support when the Starks call for aid, declaring, "The knights of the Vale will ''stay'' in the Vale where they belong, to protect their lord."
* ''Series/{{Supernatural}}'''s first order of business after [[OurAngelsAreDifferent inventing a cavalry]] was [[JerkAss inventing reasons]] [[LawfulStupid for that cavalry not to help]]. The angels as a faction are stuck in a revolving door between this and CavalryBetrayal. Refusal to answer the call happens regularly, but here are some notable examples:
** Castiel turns down Dean's pleas in Season 4's [[MetaFiction The Monster at the End of this Book]], although he does [[CouldSayItBut offer]] [[LetsYouAndHimFight a creative solution]].
** [[TricksterArchetype The Trickster]] refuses to help the Winchesters when they come calling on the eve of Armageddon. [[ChangedMyMindKid It doesn't take]].
* Played oddly in one episode of ''Series/BurnNotice''. [[FanNickname Team Westen]] is trying to get rid of a [[TheMafia Mafia capo]] who's leaning on their client, which in the end comes down to hiring a bunch of scary looking guys to act as a replacement for his soldiers (the heroes have convinced the capo that his crew is no longer reliable). Then they get him to try and assassinate his boss, and then have the crew pull out at the critical moment.
* In ''Series/{{Firefly}}'', at the Battle of Serenity Valley, the independents pull this on Mal's squad, ordering them to lay down arms rather than providing the air support they had promised. Of course, whether or not said air support would have turned the tide of the battle is unknown; given it was the last battle and the sky almost immediately went black with the number of arriving Alliance ships, probably not.

[[folder:Pro Wrestling]]
* Happens whenever a face (usually John Cena) and a heel are forced to be tag team partners. The heel will let the face take a beating and refuse to tag in or help him.
* This pretty much happens whenever a face is getting a beatdown. The other faces in the back will rarely come to the rescue no matter how many heels are doing the beating. Whereas if a face is beating a heel, all the heel's friends will come to help. Yes, in ProfessionalWrestling, the bad guys are more loyal than the good guys.

[[folder:Video Games]]
* In the [[http://www.youtube.com/watch?v=EOEGudEoSW4 introduction video]] to ''VideoGame/StarCraft: Brood War'', a Terran colony finds itself the target of a literal ZergRush; a Terran warship from a different faction shows up overhead, but promptly leaves again without doing anything for the besieged Terrans on the ground.
* Zigzagged in the [[KarmaMeter Renegade]] option at the end of ''VideoGame/{{Mass Effect|1}}''. [[spoiler:Shepard calls in the Systems Alliance Fifth Fleet under Admiral Hackett to stop the geth led by the Reaper ''Sovereign'' from starting the Reaper invasion. In the Renegade route, the fleet bypasses the ''Destiny Ascension'' and heads straight for the Citadel. Citadel ''space'' is saved by TheCavalry, for a couple years at least, but its ''leaders'', trying to escape aboard the ''Destiny Ascension'', die a fiery death at geth hands.]]
* At the Battle of Ostagar in ''VideoGame/DragonAgeOrigins'', the Warden is sent to light a beacon to signal Teyrn Loghain's reinforcements. When Loghain sees the beacon, he orders his forces to withdraw, allowing the Darkspawn to slaughter King Cailan's forces. Loghain does this because he believes the Darkspawn aren't massing in a true Blight[[labelnote:*]]false[[/labelnote]] and that Cailan's in bed with Orlais, the nation he fought bitterly against for Fereldan's freedom.[[labelnote:*]]True: As established in the "Return to Ostagar" DLC, Cailan's trying to arrange for himself to divorce Loghain's daughter and marry the Empress of Orlais.[[/labelnote]] Both in and out of universe, there's debate on this point. The survivors of the main army insist it was a cowardly betrayal as above, but Loghain and everyone from his army insist the king was beyond saving by that point (in the actual scene the king died ''seconds'' later but it's presented in a way that means a time skip is possible), and all charging would accomplish is getting the relievers all killed by overwhelming Darkspawn numbers. The only neutral observer simply says he quit the field, and according to Solas in the third game the reproduction of the battle in the fade shows both versions.

[[folder:Web Comics]]
* ''WebComic/ParanormalMysterySquad'': A greater demon named K'aannl'ngua is set on attacking Las Vagas. The US military prepares to defend the city, but is then ordered to stand down by an AnimalWrongsGroup activist with a presidential order declaring K'aannl'ngua an endangered species. The military then pulls out and lets Las Vegas get wrecked while the heroes have to defeat it alone.

[[folder:Western Animation]]
* ''WesternAnimation/JonnyQuestTheRealAdventures'': That's what drove Ezekiel Rage into becoming a criminal. [[FaceHeelTurn He was a good guy]] until falling victim to the trope - he was a spy for the U.S. Government when his cover got blown, which got worse when it turned out he brought his family along as a cover. He called for assistance and they refused to bail him out. His car ran off the road, killing his wife and daughter and leaving him horribly scarred and a whole lot messed up.

[[folder:Real Life]]
* Britain and France in the UsefulNotes/SpanishCivilWar (see the page quote). They took this trope UpToEleven by enforcing an ''arms embargo'' against the Republicans, on whose side they were supposed to be. In theory, there was an international embargo against both sides. In practice, UsefulNotes/NaziGermany and UsefulNotes/FascistItaly supplied the Nationalists with weapons, aircraft and auxiliary troops; the USSR similarly aided the Republicans, but on a much smaller scale. Only Britain and France actually upheld the embargo, in an attempt to appease Germany and prevent -- or rather, forestall -- UsefulNotes/WorldWarII.
* The USSR did this to Poland towards the end of UsefulNotes/WorldWarII. As the Red Army drew close to Warsaw, the Polish [[LaResistance Home Army]] rose up against the German occupation forces -- but the Red Army had other priorities and did not come to their aid. The British offered to send planes to help, but they were denied access to Russian airbases. Needless to say, this ended badly for the Poles. Then again, if the Poles really considered the Red Army to be TheCavalry at all, it was at most in an EnemyMine way, considering [[http://en.wikipedia.org/wiki/Katyn_massacre the kind of things]] the Russians had done to them only a few years before...
** In Russian historiography these actions are usually excused by the nearest Red Army units exhausted in a protracted offensive and thus largely combat-ineffective. However, said historiography quickly proceeds to shift blame to the Poles for not coordinating with Moscow, and accuse them of [[WeAREStrugglingTogether trying to take over Warsaw without Soviet help]] so that the Soviets would not be able to set up a Communist puppet government ([[ProperlyParanoid which is exactly what happened]]).
** Other theories suggest that the Soviet leadership ordered the halt of the offensive explicitly to [[LetsYouAndHimFight allow the Polish Home Army rise up, tie up the German garrison, and then be crushed by German reinforcements]], enabling them to come in and claim Warsaw without having to worry about a fully-functioning German defence ''or'' an active Polish resistance, making it as much of a CavalryBetrayal as a Refusal.
* During the [[UsefulNotes/VietnamWar Battle of Lang Vei]], Col. Lownds of the 26th Marines refused to send reinforcements to support the Green Berets and South Vietnamese militiamen being attacked by North Vietnamese tanks out of fear that his men might be ambushed en route, contributing to the disaster.
* During the Hungarian Revolution of 1956 against the Soviet Union, the US and other Western countries welcomed and encouraged the revolutionaries to not give up, but when the Soviets sent an army to crush it and things turned ugly, they didn't intervene, not even in a diplomatic way. The USA was, of course, accused of encouraging a suicidal revolution, just to show the world how brutal the Soviets are. Meanwhile a lot of revolutionaries died with the belief that the American help is just about to arrive.
* At the start of UsefulNotes/WorldWarI, the Triple Alliance's (German Empire, Austro-Hungarian Empire and Kingdom of Italy) plan for all-out war against the Triple Entente (United Kingdom, France and Russia) included, among other things, a two-pronged attack on France, with Germany invading from the north through Belgium and Italy invading from the south through the Alps and the coastal plains. The Italian government, between having a border contention with Austria-Hungary, the king having a personal and justified grudge with the German emperor and the country actually being in much better relations with France and Britain than with their own allies, cited Vienna declaring war first as a reason for staying neutral, [[LoopHoleAbuse as the treaty was supposed to work only for]] ''[[LoopHoleAbuse defensive]]'' [[LoopHoleAbuse wars]]. [[CavalryBetrayal Italy would later enter the war on the Entente's side]].
** Arguably it wasn't a case of LoopholeAbuse, but rather one of ExactWords. Besides, other than being defensive in nature, the alliance treaty said that in a crisis there would be consultations to decide what to do, while instead Germany and Austria-Hungary kept Italy in the dark, not to mention that in case of victory Austria-Hungary had no intention of giving Italy the compensation the same treaties stipulated, although understandingly so. Sure, Italy was definitely not happy in the alliance and was looking for a way out, but in the end its allies' behavior gave them plenty of excuses to opt out.
* The Republic of China would have stood a much better chance of resisting the Japanese invasion - or, at least, slowing them - [[http://en.wikipedia.org/wiki/Second_Sino-Japanese_War#Relationship_between_the_Nationalists_and_Communists had the Guomindang (KMT) and Communists (CCP) been able to work together]]. Instead, the Communists retreated to Yan'an and stayed out of it, for the most part.
** The Japanese advance only slowed as a result of the Allies entering the war in 1941 - which could be seen as an example of [[TheCavalry The Cavalry]] in this case.
** The CCP's Cavalry Refusal ultimately contributed to their victory over the KMT in the Chinese Civil War.
* The Cumberland Hussars at the battle of Waterloo. They not only refused to charge the French (a literal Cavalry Refusal), but then withdrew from the battlefield and were last seen forming a defensive line just outside the city of Brussels.
