->"''Wipe this pathetic planet from the face of the galaxy!''"
-->-- '''[[BigBad Darth Malak]]''', ''Franchise/StarWars: VideoGame/KnightsOfTheOldRepublic''

StockPhrase of a villain that signifies a KickTheDog, especially if the victims are (comparatively) helpless. If the villain isn't the one directly causing mass murder or ordering his {{mooks}} to do it, then he's shown giving this instruction to a PsychoForHire or HitmanWithAHeart. The naval expression for this is "No Quarter". In RealLife, it's a [[UsefulNotes/TheLawsAndCustomsOfWar war crime]].

Of course, if a DoomedHometown suffers this fate, then it's more likely than not that the hero [[GenocideBackfire escapes such a culling]] and goes on a RoaringRampageOfRevenge.

SinkTheLifeBoats is the subtrope dealing with killing enemies who were alive after being left [[KickThemWhileTheyAreDown defeated]] and [[WouldNotShootACivilian helpless]].

Compare, contrast with KillEmAll, ShootEverythingThatMoves, and RocksFallEveryoneDies. Going one step further from "kill everyone" to organized torture, looting, ''and'' massacre of the population is RapePillageAndBurn. If you have to kill everyone because they saw too much, that's LeaveNoWitnesses. When this fails, it often falls into the category of GenocideBackfire. See also TraumaticCSection.

* Anime/NeonGenesisEvangelion: In ''End Of Evangelion'', the [[KaijuDefenseForce JSDF]] raid adopts this policy as they attempt a violent takeover of NERV.
* The first episode of ''Anime/CodeGeass R2'' demonstrates the cruelly brutal efficiency of Britannian special forces by having them burn the bodies of the people they slaughtered (both Japanese and fellow Britannians)... even as some of the "bodies" are screaming, as they are not quite dead.
* [[spoiler:Colbert]] receives orders to do this to Agnes's DoomedHometown in ''LightNovel/ZeroNoTsukaima'' qualifies as this. She initially thought her town was destroyed for heresy; whereas Colbert was instructed to burn the town to the ground because of plague. RoaringRampageOfRevenge ensues for Agnes, [[spoiler:MyGreatestFailure for Colbert]].
* In {{Claymore}}, we have one the BigBad ordering TheDragon to "annihilate Pieta. Basically, a place where no lifeforms exist whatsoever. That is what I want Pieta to become."

* Ildomir the EvilSorcerer from ''{{Nodwick}}'' makes a note to himself to have this phrase tattooed on the back on his hand after being foiled by our heroes shortly after leaving them alive in a bad situation.
* In the flashback section of ''Recap/TintinTheSecretOfTheUnicorn'', after being hit by a broadside, the pirate ship hoists the red flag, signaling that they would not take prisoners. They do capture captain Sir Francis Haddock when a golden opportunity presents itself, but plan to execute him slowly the next morning.

[[folder:FanFiction]]
* In [[http://www.fimfiction.net/story/90939/shell-shock Shell Shock]], the captain orders his troops to do this to a large group of freshly captured POW's. It's as much for revenge as it is a sign for just how fucked up things are.
[[/folder]]

[[folder:Films -- Animated]]
* ''WesternAnimation/ThePrinceOfEgypt'': In the climax, Rameses and his army pursue the Hebrew refugees, during which he orders his men to kill all the unarmed Hebrews. Utterly ironic as well; all his life Rameses [[WellDoneSonGuy tried to be a greater Pharaoh than his imposing father Seti I ever was]]. Without realizing it, he tried to outshine his father's legacy even in something as extreme as mass murder.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Film/IronMan'': Stane, just after paralyzing Raza and his goons with some experimental technology outlawed by the government, orders his personal bodyguards to clean up the mess.
* ''Film/LawrenceOfArabia'': has the titular protagonist quite pissed off at enemies who just slaughtered a village: '''NO PRISONERS! ... NO PRISONERS!!'''
** In real life, he usually had his men take prisoners, but on one occasion, when ''really'' pissed off, told them, "The best of you brings me the most Turkish dead!"
* ''[[TheChroniclesOfNarnia The Lion, the Witch, and the Wardrobe]]''
-->The White Witch: I have no interest in prisoners. Kill them all.
* In the film version of ''Film/TheLordOfTheRings'', this happens twice. Saruman orders his Uruk-hai in the second film to '''"leave ''none'' alive!"''' in the battle of Helm's Deep, and the Witch-king orders his minions to slay everyone in Minas Tirith.
** "Release the prisoners"
** Also at Helm's Deep, Aragorn himself tells the defenders to show no mercy to their besiegers, "because the enemy will show none."
* Also done by Durza in ''Film/{{Eragon}}'' in a very similar scene.
* From the ''PiratesOfTheCaribbean'' films:
** In the first film, of course, the cursed crew of the ''Black Pearl'' is famous for leaving no survivors.
-->'''Jack:''' [[LampshadeHanging No survivors]], eh? [[UndeadAuthor Then where do the stories come from]], I wonder?
** ''Pirates of the Caribbean: Dead Man's Chest''
-->"What about the survivors?" "There ''are no survivors''."
** Also in ''At World's End'':
-->'''Beckett:''' Signal Jones to give no quarter. That should brighten his day.
* ''Film/ThePrincessBride'': The standing order of the Dread Pirate Roberts, though with a condition: Only those who attempt to fight back are killed.
** Not to mention the threat the heroes use to clear out the men guarding the castle gate on their way to rescue Buttercup.
* ''Film/{{Spartacus}}''. The phrase is not uttered, but all of the surrendered slaves are crucified (except for the Hero and his [[TheLancer second in command]], who are ordered to fight to the death to see which one of them ''doesn't'' face the grislier execution).
* ''Franchise/StarWars'':
** In ''Episode I: Film/ThePhantomMenace'', upon being told that the Gungans were massing for battle, Darth Sidious orders the Trade Federation to "Wipe them out. ''All'' of them."
** ''Episode III: Film/RevengeOfTheSith'' has the same guy ordering the newly christened Darth Vader to wipe out Viceroy Gunray and the other Separatist leaders. As well as, a few scenes earlier, the Jedi at the Temple.
---> '''Sidious:''' Every single Jedi, including your friend Obi-Wan, is now an enemy of the Republic. Do what must be done. Do not hesitate. Show no mercy.
* In ''Film/TomorrowNeverDies'', the number of survivors from the sinking of the British frigate reaching the villain's ship very neatly matches the number of dead he reports as washing up on the beach.
* In ''Film/StarTrekIITheWrathOfKhan'', after Saavik goes through the Kobayashi Maru test, Kirk tells her that the Klingons don't take prisoners. Since they ''do'' take prisoners in several ''Series/StarTrekTheOriginalSeries'' episodes as well as several TOS era movies, this is probably based on a faulty memory of the "Romulans don't take captives" quote from TOS.
** Although the earlier instances are contradicted by the later and more consistent representation of Klingons as ProudWarriorRace guys who consider being taken prisoner a fate worse than death. Death in combat is a notably DESIRABLE thing for a Klingon Warrior, such that any who do not fall IN BATTLE must have a victory won in their name in order to enter the Klingon Heaven ([[strike:Valhalla]] Sto-Vo-Kor). Given all that, it seems unlikely they would engage in such "dishonorable" conduct as TAKING prisoners.
*** And, given the conditions seen on Klingon ships (spartan and probably with only enough supplies to sustain the crew itself for its length of mission), it's doubtful they would have '''had''' the capability to take prisoners, sort of like the RealLife submarine example closing out SinkTheLifeboats.
** The "prisoners" line probably stems from the opening scene featuring Romulans instead of Klingons. The KM test is in Gamma Hydra near the Neutral Zone -- near the Romulan Empire in TOS. Also, the Klingon Bird of Prey in ''Film/StarTrekIIITheSearchForSpock'' was originally designed as an update to the TOS Romulan ship (Klingon didn't use Birds of Prey until that point). The decision to switch from Romulans to Klingons was apparently made by the writers at the suggestion of Leonard Nimoy, who felt they made better bad guys.
** Or Kirk was just being dramatic.
* ''Film/RedDawn1984''. The protagonists are seen shooting Soviet prisoners and wounded, because they're fighting a guerrilla campaign and can't take prisoners even if they were so inclined.
* The same occurs with German soldiers in ''Film/{{Defiance}}''.
* In ''AnimalHouse'', while wrecking the parade, Bluto shouts "Take no prisoners!"
* This was Blackout's intention in the opening scene of ''Film/{{Transformers}}''. He attempted to hack into the military defense network in order to obtain any information about the whereabouts of Megatron and the All Spark, but was cut off by the base commander. When Epps manages to take a digital snapshot of him, he dispatches Scorponok to eliminate the escaping soldiers, whilst he deals with everyone else on base. The investigation conducted in the aftermath reveals that he killed every single person on site. Scorponok however, whilst succeeding in killing/wounding two soldiers, failed to eliminate the rest of the group before they could call for help.
* ''ItHappenedHere'' ends with LaResistance massacring captured members of the British SS, as part of its [[TheRevolutionWillNotBeCivilized deconstruction of heroic resistance tropes]].
* In ''Film/JudgeDredd'', Judge Griffin says this in so many words to his people who are investigating the shuttle crash.
--> '''Griffin''': You are in error, Capture Team. No one survived the shuttle wreck.
* ''WeWereSoldiers'': The Viet Minh commander gives this order after defeating a French column during the film's prologue.
--> '''Nguyen Huu An''': ''Kill all they send... and they will stop coming. ''
* In ''RedTails'', "Pretty Boy", the German fighter ace, typically opens the fight with some order or another. By the final battle, he has lost all pretense of gentlemanly chivalry and simply orders his men to show no mercy.
* ''Alexander the Great'' (1956). After being abandoned by the Persians, the commander of the Greek mercenaries who fought against Alexander asks for quarter. Alexander refuses, saying they're traitors (even though they haven't sworn an oath to him) as he's ruler of all the Greeks. The mercenary commander asks again, not for himself but for his men. Alexander refuses this offer also. The commander says in that case they'll fight to the death. None of them escape alive.
* ''Film/StarTrekIntoDarkness'':
** [[spoiler:Admiral Marcus]] has no intention of letting any of the ''Enterprise'' crew live even after Kirk pleads that [[TakeMeInstead he alone should be punished]] for his command decisions.
** Every Klingon who witnesses Harrison ends up dead.
* ''Film/TotalRecall1990'': When Richter and his men pursue Quaid and Melina into the mutant district, they escape and Richter shoots the first person who refuses to answer him. When they retaliate, he orders the soldiers to kill everyone and barely escapes from the ensuing slaughter himself.
[[/folder]]

[[folder:Literature]]
* In ''Literature/TheHuntForRedOctober'', the US wonders what to do with the crew of ''Red October'', who don't want to defect--rejecting the option of killing them all as morally wrong. The reason the sub's destruction is faked is in order to allow the crew to go back to the USSR and claim the sub sunk.
* In the final ''Literature/ProtectorOfTheSmall'' book, Keladry has to give this order twice while sneaking a band of people into enemy territory, and neither time does she like it. But they don't have the luxury of keeping prisoners and they can't let them go to warn the enemy where they are. A rare heroic example.
* In [[Literature/TheDresdenFiles Changes]], the Red Court strike teams like to operate this way to send a message to their enemies.
* Narrowly averted in ''[[Literature/HonorHarrington Echoes of Honor]]''. When the combined Grayson-Manticore fleet with the new [[MacrossMissileMassacre podnaughts]] rides to [[spoiler: the defence of Basilisk]], Earl White Haven nearly has a heart attack when he thinks Admiral Yanakov ordered no quarter. Fortunately, the latter only called for no mercy. While any ship in range conceivably capable of fighting is blasted to pieces, the escape pods are left alone.
** But invoked in the Echoes' Children filksong ''No Quarter,'' based on the book.
* In the ''Literature/ConfederationOfValor'' series, the Others are well known to not take prisoners. Which confuses the characters intensely in ''Valor's Trial'': They're in a POW camp. TheReveal? [[spoiler:It isn't run by the Others, a.k.a. the Primacy.]]
* In ''Literature/OutOfTheDark'', Shongairi soldiers attempt to surrender, but when Buchevsky again sees the children they have killed, he is reminded of his own killed daughters and has them all killed.
* VladimirVasilyev's ''No One but Us'' involves a SpaceBattle where TheAlliance fleet (mostly made up of human ships) conducts a surprise attack of a [[TheEmpire Shat Tsur]]-held planet and has successfully made four passes through the enemy forces, dealing enormous damage to the defensive ships and orbital installations. When the defenders start flashing the universal surrender code with their running lights, the fleet commander orders the fleet to continue making passes, realizing that this is a ploy by the defenders to bog down TheAlliance fleet with tons of prisoners. Only after two more passes does the fleet commander order the taking of prisoners. This is the only time this happens, though, as they quickly find out that the oppressed planetary populations are more than happy to watch the prisoners for the Alliance, freeing the fleet. The Shat Tsurs, though, don't like to take prisoners, especially where their former masters the [[WingedHumanoid Aczanny]] are concerned. By the time of the novel's events, 70% of the Aczanny race has been wiped out, most of them during the first few months of surprise attacks.
* The mildly insane royals do this in TalesOfTheBranionRealm, especially in ''The Stone Prince'' where the coldbloodedness and strength of mind necessary to be merciless is part of the protagonist's training by his mother. She is known for having hanged a hundred rebels at once, calmly discussing tactics with her aides while the sentence was carried out.
* ''Franchise/StarWarsExpandedUniverse'':
** One of Boba Fett's targets in [[Literature/TalesOfTheBountyHunters "The Last One Standing: The Tale of Boba Fett"]] is Kardue'sai'malloc, who earned his moniker "{{the Butcher}} of Montellian Serat" for slaughtering hundreds of Rebel [=POWs=] on Devaron. He claims he was forced into it by his superiors: He had been ordered to join up with another force after taking the city of Montellian Serat and not to leave anyone behind to guard the prisoners, and he didn't have the resources to bring them with him either, so...
** In ''[[ComicBook/XWingSeries X-Wing: The Bacta War]]'', [[BigBad Ysanne Isard]] orders her minions to pick a random rebel target and wipe it out.
---> '''Isard:''' Find it and destroy it. No warning, no mercy. No question who the true power is.
* The pirates in ''Literature/AllHands!'' all get killed when the Starcougar [[RammingAlwaysWorks rams]] their ship.
* During the third book of TheHungerGames, [[AntiHero Gale Hawthorne]] suggests a plan to destroy a Peacekeeper Fort by causing an avalanche. Not content to [[WouldBeRudeToSayGenocide just kill the majority of those inside]], he also suggested [[KickTheDog bombing the escape to ensure they all die]]. His reason for this is that [[HeWhoFightsMonsters Peacekeepers destroyed District 12, so he is out for revenge]].

[[folder:Live-Action TV]]
* ''Series/BabylonFive'':
-->'''President John Sheridan:''' Hit-and-run attacks, very efficient. No survivors, no warning.
** Minbari policy during the Earth-Minbari War was to destroy any and all combatants, regardless of their ability to fight back or if they surrender. Granted, they did leave many core colonies untouched as they made a beeline for Earth. However, it's likely they would've gone back to mop up every surviving human after Earth was no more.
** Sheridan {{exploited}} this tendency in the ''Black Star'' incident that earned him the moniker "Starkiller". With his ships damaged in a prior attack, he sent a fake distress signal, knowing the Minbari would come back to finish the job. Then he laid a minefield between him and the direction in which the Minbari ships had left, and waited for them to take the SchmuckBait.
* ''Series/BattlestarGalacticaClassic'': In the original series:
-->'''Imperious Leader:''' There can be no survivors. [[KillAllHumans So long as one human remains alive]], the Alliance is threatened.
* ''Series/RedDwarf'': Comedic version: In one episode, a shuttle crashes and most of the gear on board is wrecked. While trying to find something worth salvaging:
-->'''Kryten:''' At least [[DreadfulMusician Mr. Lister's]] guitar survived intact.
-->(Cat smashes the guitar to smithereens against the wall)
-->'''Kryten:''' Not even Mr. Lister's guitar survived intact!
* ''Series/{{Revolution}}'': The title of the episode "[[Recap/RevolutionS1E3NoQuarter No Quarter]]" is the same as the alternative name of this trope. This episode features the Monroe Republic fully intending to kill off every single rebel they find. The only reason they left one group of rebels alone was because [[spoiler: they exchanged Miles Matheson in return for being spared]].
* ''Series/StargateAtlantis'': There's a heroic version. After repeatedly failing to kill Michael, and now dealing with his latest scheme which has taken control of the city, Sheppard orders the soldiers to give no quarter.
* ''Series/StarTrekDeepSpaceNine'':
** {{Exploited}} by Sisko and Klingon General Martok before full-scale war broke out. The ''Defiant'' and Martok's IKS ''Rotarran'' would take turns sitting in space sending out a fake distress signal and wait for the Jem'Hadar to come by looking for an easy kill, whereupon the other ship would decloak and blindside them.
** Upon having the Cardassians rebel, the female ShapeShifter gives the order to kill every last one of them. Her only response to being told "That's going to take some time." is "Then I suggest you begin at once." Fortunately, our heroes manage to prevent it being completed (in part because most of the guards at Dominion HQ were sent out to kill Cardassians), but over eight hundred million are still killed during the attempted genocide.
* ''Series/StarTrekTheOriginalSeries'':
** The Romulans are noted to not take captives in the 2nd season episode "The Deadly Years". However, they try to do exactly that in the 3rd season episode "The Enterprise Incident".
** Possibly they do take prisoners but they don't ransom them, they keep them and refuse to acknowledge that they do. Certainly Saaviks Vulcan parent was a prisoner as was Tasha Yar.
* In the ''Series/{{Supernatural}}'' episode [[Recap/SupernaturalS01E04PhantomTraveller "Phantom Traveler" (S01, Ep04)]], a demon causing airplanes to crash vows that there will be no survivors.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'' TabletopGame/ForgottenRealms setting.
** Drow nobles have such a nice tradition. ''Literature/TheDarkElfTrilogy'' put this to use by making it completely unspoken. {{Klingon Promotion}}s are a cornerstone of drow society: noble houses move up in rank by slaughtering the house above it. However, by their definition of "justice", if even one survivor is left to accuse them, ''their'' house will be exterminated as punishment. It's kind of hard to track them all, and hard to tell when they try to disguise, so there's no need for those in command to order their soldiers to kill anything that moves and then comb the compound afterward for any secret rooms where others may be hiding.
** Later sources elucidated the details. The obvious reason for this tradition is that whenever two parties among the drow are allowed to enter a CycleOfRevenge and others start taking sides, this eventually ends in an open civil war and complete destruction of the city. Naturally, with such prospects the rest of a community prefers to limit the damage to those already involved. Thus if two Houses begin an assassination war or other escalating hostilities, others will ''push'' them into an open attack as soon as possible -- one side ceases to exist, the conflict ends. This also is applied only to legitimate members of the House, i.e. anyone who officially switched allegiance to another House, mercenary band or merchant clan doesn't belong to the House which gets eradicated/accused; this doesn't happen every day, but one guy survived the destruction of his House with Spider Queen's personal involvement without as much as leaving his city.
* Not an uncommon position for player characters to take with regard to enemy {{NPC}}s, for reasons ranging from in-game practical considerations to the infamous "they aren't worth experience points alive" (though it's worth noting that the latter hasn't been true for "modern" tabletop [=RPGs=] for at least a couple of decades by now). While non-player characters are of course technically not "real", this can still cause friction with other actual people at the table (players and {{Game Master}}s both) who might not be as comfortable with the "ruthless killing machine" approach to "heroism".
* TSR's ''Chainmail'' miniatures rules. Swiss, Landsknecte and Turkish troops do not take prisoners as a matter of policy. In any situation where opposing troops would surrender, they are considered killed instead.
* In Warhammer40K, leaving no survivors (on the table) of the enemy's force is generally an alternative win condition to the particular game's objectives. This is known as "tabling" the opponent.

[[/folder]]

[[folder:Video Games]]
* Every game that requires the player to eliminate all enemies to advance to the next level/unlock a new area/complete a mission falls into this trope. (Aversions fall under InstantWinCondition.)
* ''VideoGame/CommandAndConquerRedAlert'':
** In the first Soviet, your superiors order you to annihilate a rebel village.
-->'''[[SmugSnake Gradenko]]:''' Let's see how [[NonEntityGeneral you]] handle this. Go at once to [[DoomedHometown Torun]], [[ObligatoryWarCrimeScene destroy everything and everyone.]] [[KillEmAll No prisoners,]] [[ExactlyWhatItSaysOnTheTin no survivors.]] [[MoralEventHorizon That is all.]]
** Similarly, General Eislin of the Allies tells the player during the campaign in Kiev to destroy EVERYTHING in the Soviet nuke base. "Scorched Earth!"
* ''VideoGame/CommandAndConquerTiberianSun'': During the first Nod briefing, commander Anton Slavik asks Cabal what the conditions for a favorible outcome against the renegade General Hassan's forces in the present engagement would be. Cabal's response: "THEY ALL DIE!".
* In ''VideoGame/FinalFantasyVI'', [[MonsterClown Kefka]] gives an order to this effect in one of Terra's flashbacks during a ''training exercise'' (for [[{{Tykebomb}} her]], not the helpless [[RedShirt troops]] being cut down, but it still comes off as unnecessarily callous).
* The player character in the ''{{Freespace}}'' expansion pack ''Silent Threat'' gets to do this in the first two missions, in order to protect a fragile alliance with an alien race after a friendly fire incident (the second mission: one ship was scripted to escape the first mission, so you went to its destination and killed everything there).
* ''VideoGame/SkiesOfArcadia'''s BigBad would have done this when he [[DoomedHometown doomed Vyse and Aika's hometown]] if the Air Pirates had resisted capture. Luckily, they didn't, so the non-combatants were spared and you got to rescue everyone else later.
* Drek'Thar gives this order with his buff in ''VideoGame/WorldOfWarcraft''.
** Also in World of Warcraft, this is one of Sylvanas' quotes if she's ever under attack by an Alliance raid
--> '''Sylvanas Windrunner:''' "Let none survive!"
* ''TabletopGame/{{Warhammer 40000}}'' in one of the DawnofWar Imperial Guard campaigns, you get to witness the fate of captured Chaos Cultists.
** Justified in the Warhammer40k verse since you can not take any chances with Chaos.
* As indicated by the opening quote, Darth Malak in ''KnightsOfTheOldRepublic'' orders to destroy the entire planet of [[spoiler:Taris]]. Yes, StarWars's Sith like this trope.
* Referenced by ''VideoGame/CallOfDuty 4: ModernWarfare'', ''World at War'' and ''ModernWarfare 2'' at the beginning of multiplayer matches as Russian forces - the first and third have their announcers say "Take no prisoners, comrade.", ''World at War'' has GaryOldman say "Show courage, show pride, ''but show no mercy!''" On the other hand, there is no gameplay mechanic to take prisoners anyway...
** And in World at War's single player, GaryOldman's character encourages you to kill a group of surrendering Germans. If you don't do it yourself, he'll just kill them anyway.
** Then there's No Russian from Modern Warfare 2, which is the inciting event of the game's entire story.
* Having won the ultimate victory in {{Starcraft}}:Brood Wars, Kerrigan denies the defeated Earth admiral a chance to surrender his troops and mockingly offers his fleet a head start before sending her HordeOfAlienLocusts after it. They devour every last one of them.
** In the Episode 0 {{Starcraft}} campaign Loomings (which got released as free shareware), a Confederate magistrate sends you, a lieutenant in Alpha Squadron, off to take care of a Sons of Korhal uprising by saying in your mission briefing: "There are to be no arrests, Lieutenant. I hope you understand what I mean. I want this problem solved once and for all."
* ''VideoGame/DawnOfWar 2'' has "NO MERCY!" amongst the random battle dialogue of the Space Marines. Naturally, there are no mechanics for taking prisoners in the game.
* In ''VideoGame/{{Patapon}}'', one of the things your Patapons can say is "Take no prisoners!" (And indeed you're committing WaddlingHead genocide.)
* In ''VideoGame/{{Homeworld}}'' and even more so in ''Homeworld 2'', setting a vessel to aggressive tactics is usually met with the ship captain responding "Weapons set to full power. Show no mercy."
* While not specifically mentioned in the ''TotalWar'' series, starting with ''Empire: Total War'', it is no longer possible to take prisoners in battle. In ''Medieval'', ''Rome'', and ''Medieval 2'', any enemy struck from behind was knocked out instead of killed and taken prisoner if you win the battle. You could then free, execute, or attempt to ransom (execution as backup) them back.
** This is probably an aversion, however, since it was about this time that rules about taking prisoners started to be enforced. The likelihood is that the winner ''is'' taking prisoners, but since you have no legal choice about whether to kill them or not it's just being quietly taken care of behind the scenes.
*** Maybe, but they're still listed in the "Killed" column.
*** ''Shogun 2'' also doesn't allow the taking of prisoners.
* This is a favorite habit of ''SuikodenII'''s Prince Luca Blight when ransacking random towns throughout the game. If fact, he takes it a step further by personally and gleefully butchering all of the inhabitants individually while they beg for their lives.
* In ''{{Spore}}'', this is the only way to conquer an enemy tribe/civilization/planet if yours is warlike. (It can be subverted if you choose to win over the others with music/religion, or with money.)

[[folder:Real Life]]
* From ancient times there has been an unspoken rule that if the defenders of a city involved in a siege surrendered, averting the major battles and casualties that results from sieges and siege breaking, they would be treated relatively nicely. The alternative was that once the attackers broke the siege, generally incurring heavy casualties, they pretty had the right to completely destroy the city and slaughter the inhabitants in order to "encourage" the surrounding cities to surrender.
** Mongols practiced this to the letter, to the point of killing not only all the people but also all the animals and piling their skulls in huge pyramids. Such massacres were comparatively rare, however, since the frightful reputation of the Mongols caused so many of their enemies to surrender without a fight to avoid such fates.
* Littoral and archipelago warfare in general. Islands tend to be defended to the last man, and there are few facilities on tending the wounded and the prisoners.
* The Alamo, The Battle of Thermopylae, and several other {{Last Stand}}s where the defenders were so effective (and/or annoying) that the victorious attackers finished off whatever survivors, wounded, or captured noncombatants they got their hands on afterward.
* The Massacre of Glencoe was ordered by King William of Orange with the line:
-->''"You are hereby ordered to fall upon the rebels, the [=McDonalds=] (sic) of Glenco (sic), and put all to the sword under seventy".''
** The part about leaving those over 70 was not mercy; in those days it was rare to find anyone much over 50 and the understanding was that anyone 70 or over would probably die on their own without someone to provide care for them.
* This is frequently applied by a force that manages to defeat one much larger than them - they can't maintain so many prisoners, so the logical thing to do is to kill them all.
** Also the case with insurgencies; who when they do take captives, have neither the institutions to put them on trial nor the facilities to detain them, so are left with no choice but to execute or release them back into the regime's forces.
* Famously happened during the Albigensian Crusade against Catharism in southern France. Asked by a soldier how to tell the difference between Cathar heretics and good Catholics, the [[ChurchMilitant Papal legate]] [[KnightTemplar Arnaud Amalric]] replied:
-->''"Kill them all. The Lord will recognize his own."''
** This may be apochryphal, as exactly the same comment is ascribed to the man who captured Jerusalem in the First Crusade and was posed with the problem of sorting good Christians out from pernicious Jews and Moslems.
** Though it's debatable [[BeamMeUpScotty if he said]] any such a thing, as there doesn't seem to be any record of him saying those words until about 50 years afterwards.
* Arguably the result of any protracted siege in history. The soldiers, after watching their mates getting killed in various horrific fashions over a period of weeks or months, take out their frustrations on the defenders and civilians inside.
* The [[{{Pirates}} Jolly Roger]]. In real life, the Jolly Roger was a ''good'' thing (assuming you were being attacked by pirates), as it meant that the pirates would accept prisoners. However, a blood red flag meant "No Quarter".
** Both flags and their respective meaning are used in the flashback segment of the ''{{Tintin}}'' book ''The Secret Of The Unicorn''.
* In [[TheRomanEmpire Roman Conflicts]], once the battering ram was deployed, it was the signal that no prisoners would be taken, even as slaves. The ''Series/{{Rome}}'' episode "The Ram Has Touched The Wall" ("Murum aries attigit") explains this.
** To extend the explanation: when a (Roman) army approached a hostile city and the city surrendered before arrival, the city's inhabitants and possessions were sacrosanct, and there would be no (official) looting or pillaging. If the city held out, but surrendered before the siege engines were in place, the citizens who fought (those of fighting age) were taken as slaves and the city looted, but no (official) rape or other destruction would take place. If the siege continued to the full, and the city overrun, the invaders could do as they pleased, and the commanders either looked the other way or actively encouraged their troops. This even applied to Roman cities, such as those on Sicily, after they rebelled. There are accounts of Legionaries who expressed the hope that the city would not surrender, so they could get some good looting and rape in.
** The city of Carthage was completely destroyed by the Romans at the climax of the Third Carthaginian War. The Carthaginian citizens were either slaughtered or captured as slaves; none were spared.
** Roman deserters were always killed if captured by Rome. There were accounts of ex-Roman soldiers at Carthage building a great bonfire in the Basilica before it fell, and leaping into the flames to avoid mandatory crucifixion for their desertion.
*** Shown in ''SpartacusBloodAndSand'': The Thracians who deserted the Roman forces were killed or taken into slavery, along with those of their villages.
* Civil War Union General Tecumseh Sherman first coined the term "total war" (which was a variant of this) and used it as a strategy against the Confederate army. Military historian B. H. Liddell Hart referred to him as "the first modern general".
* The Battle of Little Bighorn.
* Most of WorldWarII in the Pacific Theater was this, especially after the tide turned and the Americans began their slow advance towards Japan. The Japanese refused to surrender in any significant numbers, preferring one LastStand after another, while at the same time refusing to take any prisoners when one of their counterattacks was successful. At the same time, Allied troops, either through lack of wherewithal to care for prisoners in some areas, or through paranoia (a well-worn tactic of the Japanese was to secret live grenades upon themselves if wounded or otherwise attack Allied troops coming to render aid) or through out-and-out hatred/reprisal, adopted an unofficial policy of not taking prisoners. This trope was so abused during the war that some units had to offer cash bounties for prisoners so that they could have prisoners from whom they could glean intelligence.
** The Rape of Nanking had an official order to kill all prisoners.
** In the European Theater, during particular battles, both Allied and German troops were sometimes ordered or "encouraged" not to take any prisoners. However, often times these orders had practical motivations. During Operation Neptune, Allied paratroopers obviously had no rear echelon or base of operations to send prisoners of war to since they were operating behind enemy lines. During the Battle of the Bulge, taking prisoners would slow down the German advance, which was on a time critical mission. Naturally, since the Allies won the war, (only) the Germans that were caught doing this were tried for war crimes.
** This was also very common in [[LaResistance partisan]] [[LesCollaborateurs warfare]]. Reasons are many:
*** Deliberate acts of terror or reprisal killings against civilians led to a CycleOfRevenge.
*** There was no area that was 100% secure, so taking prisoners meant there was a risk they would be set free (this goes double for partisans, who had to constantly move their base of operations, and prisoners would slow them down).
*** Long-standing ethnic or religious tensions between the local populace.
*** Ideological polarization (e.g. communists and fascists often neither gave nor expected quarter from each other).
*** Lack of food or medical supplies meant none could be spared for prisoners.
* The ''oriflamme'' of the French army between 1124 and 1415 was a blood-red standard and thus a signal that no mercy was to be shown. Unfortunately, they had a habit of losing it, once to the Flemish and three times to the English.
** At the Battle of Agincourt King Henry didn't have enough men to guard the French prisoners of the first wave and simultaneously repel the counterattack of the second wave. So he killed the (unransomable) commoners and spared the knights.
* This is the modus operandi of the Mexican drug cartels.
