A delaying action is a battle fought by a clearly outnumbered and out-gunned force to try and hold up a superior force. The aim is to buy enough time for other friendly forces to a) escape or b) [[TheCavalry arrive]].

This may involve a HeroicSacrifice, but ideally, you aim to perform a TacticalWithdrawal before being slaughtered. The military equivalent of either YouShallNotPass or holding a position until the BigDamnHeroes show up.

[[folder:Anime]]
* In ''Anime/GargantiaOnTheVerdurousPlanet'', Commander Kugel attempts to do this to prevent the Hideauze from following their retreating forces into the wormhole after the Galactic Alliance is forced to retreat from the battle in the first episode.
* Levi does this twice in ''Manga/TrinitySeven''. The first is against Liselotte to buy time for Mira to scan their opponent's abilities and spells, and the second is when fighting Lugh to give Arata and the others more time to get back before it's destroyed.

[[folder:Film]]
* ''Film/ThreeHundred'', recounting the Spartans at Thermopylae (see Real Life below).
* The Battle of Hoth in ''Film/TheEmpireStrikesBack''. The Rebels knew there was no way they could actually win: the Empire had better equipment (including heavy armor for which the Rebels had no viable counter) and too much of a numerical advantage. The ground forces and Rogue Squadron simply hoped to delay the Imps long enough to evacuate the base. The battle was considered an Imperial victory overall, though the Rebels technically achieved their objective. [[FridgeLogic Though did the walker speed ever really slow down at all?]]
* ''Film/WingCommander'' has a single carrier being asked to hold off an entire [[CatFolk Kilrathi]] fleet for 2 hours, while the main Confederate fleet gets into position.
* In ''Film/KungFuPanda'', Master Shifu decides to stay and fight [[BigBad Tai Lung]], despite knowing that his former student has become too strong for him, knowing that, as long as Tai Lung is fighting him, he will not attack the Valley of Peace, which is being evacuated by Po and the Furious Five.

[[folder:Literature]]
* In ''Literature/TheThirdWorldWar'', {{NATO}} successfully delays Soviet forces long enough for reinforcements to arrive, then launches a decisive strike and turns the Soviets back around Krefeld.
* In ''Red Phoenix'', North Korea invades South Korea. US and South Korean forces essentially have to fight one big delaying action until reinforcements can arrive from the US.
* [[ComicBook/XWingSeries Rogue Squadron]] did this in ''[[Literature/TheThrawnTrilogy Dark Force Rising]]'', trying to buy time for Luke and Han to get into their ships and let [[DividedWeFall Fey'lya]] escape with his force. Fortunately for them, Fey'lya was steered into an EngineeredPublicConfession and his people [[ChangedMyMindKid went back to help the Rogues]]. This wasn't enough. Karrde's smugglers showed up. This wasn't enough. Then [[BigDamnHeroes Bel Iblis showed up]]. [[HopeSpot This was enough]] until a second Star Destroyer appeared, and it took two counts of RammingAlwaysWorks before the day was saved.
** [[TheCaptain Wedge]] [[FourStarBadass Antilles]] ''loves'' these, since his particular style of warfare makes them ''work''. Case in point: the [[NewJediOrder Siege of Borleais]]. All told, the siege involved an entire fake secret engineering project, an entire ''real'' secret engineering project, a planetary bombardment ''by the garrison defenders'', a Super Star Destroyer dropping into the middle of the enemy fleet... oh, and [[CrowningMomentOfAwesome the wholesale evacuation of the garrison]] before the final battle. Borleais cost two entire Vong fleets and a planetary garrison, and was a ''huge'' embarrassment to their command staff.
** Wraith Squadron's first real action was covering the evacuation of their training base when a Star Destroyer allied to Warlord Zsinj showed up. Things go from bad to worse when one of the transports is delayed in launching, but then we get a taste of what the squadron is capable of when a pilot wonders, "what if we gave them a juicier target to go after?" Cue an improv radio program where two Wraith X-Wings and two A-Wings pretend to be the ''Millennium Falcon'' suffering some engine problems.
* In ''Literature/TheSilmarillion'', the Men of the House of Hador delay the forces of Angband long enough for Turgon's Gondolindrim to escape unfollowed. All but one of them die, and it only gets worse for the [[AndIMustScream survivor...]]
* ''Literature/HonorHarrington'':
** In the novel ''In Enemy Hands'', the heavy cruiser that Honor is on (as flag officer) jumps into a system to discover that the Havenites have already taken it and destroyed the local forces. Honor orders her ship to distract the attention of the enemy away from the point the convoy she was escorting would have jumped out of hyperspace, to give it the chance to jump back out. This done and the ship badly damaged, she orders the ship's captain to surrender the ship to the Peeps.
** In the earlier novel ''The Short Victorious War'', a large Manticoran fleet has been decoyed away from their home base at Hancock Station. A small task force left behind to protect the base has to delay the attacking Havenite fleet long enough to prevent them from either taking the station or retreating back over the hyper limit before the Manticoran fleet can return. Honor ends up [[YouAreInCommandNow in command of the task force]] during the course of the battle, although [[spoiler:her flag officer, Admiral Mark Sarnow, was only incapacitated, not killed, and shows up again in later books]].
* When a mission goes wrong in ''Literature/InvasionOfKzarch'', and the rebel forces have to beat a fast retreat with the enemy right behind them, they're forced to use a sacrificial force, made up mostly of wounded, to buy time for the main force to break away. The sacrifical force is slaughtered to a man, but they get the job done (Salutes).
* In ''Literature/ArkRoyal'', when an unexpected alien threat surfaces, and the modern [[SpaceNavy Space Navies]] prove utterly incapable of dealing with them, the British Royal Navy sends in the obsolescent titular [[TheBattlestar armored carrier]] to try to hold off the alien advance in the slim hope that her armor and [[MagneticWeapon railguns]] will allow her to survive and deal a blow to the enemy. The initial engagement is successful, and the ''Ark Royal'' ends up destroying several alien carriers, forcing a retreat. As a result, the ship is once again sent to confront the aliens, hoping to keep them away from Earth until the major space powers can design and build ''Ark Royal''-type ships.

[[folder:Live Action TV]]
* In the final episode of ''Series/RobinHood'' [[spoiler: The outlaws, who have seized Nottingham, try a gradual retreat to delay the Sheriff's forces until forces loyal to King Richard can arrive. It turns out they're not coming and a change of plan is needed]].
* An episode of ''Series/LieToMe'' features [[spoiler:a CIA agent who'd went over to the Taliban redeeming himself by delaying them long enough for Lightman and the others to escape a bunker.]]
* The Battle of the Line, in the ''Series/BabylonFive'' prequel movie ''In The Beginning'':
--> '''President of Earth:''' We have continued to broadcast our surrender and a plea for mercy. And they have not responded. We therefore can only conclude... that we stand at the twilight of the Human race. In order to buy more time for our evacuation transports to leave Earth, we ask for the support of every ship capable of fighting to take part in a last defense of our homeworld. We will not lie to you. We do not believe that survival is a possibility. We believe that anyone who joins this battle... will never come home. But for every ten minutes we can delay the military advance several hundred civilians may have a chance to escape to neutral territory. Though Earth may fall, the Human race must have a chance to continue elsewhere. No greater sacrifice has ever been asked of a people than I ask you now... to step forward one last time... one last battle, to hold the line against the night. May God go with you all."
* More than once in ''Series/FallingSkies''.
* The Second Battle of [[Series/StarTrekDeepSpaceNine Deep Space Nine]]. Against a Dominion-Cardassian Fleet, the station manages to destroy 50 ships before the Starfleet crew is forced to abandon it. Before leaving, Sisko reveals that while they had focused much of the Dominion's ships, a Starfleet-Klingon task force destroyed a major Cardassian shipyard.

[[folder:TabletopGames]]
* One special scenario in ''TabletopGame/{{Warhammer}}'''s Storm of Chaos campaign was "Halting the Tide," based around an Empire-Kislev alliance battling against the overwhelming Chaos hordes of Archaon, Lord of the End Times. The attackers outnumber the defenders two to one, but the defenders are grimly determined to tie up the attackers for as long as possible, and are immune to Panic during the battle. Another twist is that victory depends upon how many units the Defender kills, so if the Attacker completely wipes out the Defenders but loses half of his own forces in the process, it's still a loss for him.
* Several mission types in ''TabletopGame/{{Warhammer 40000}}'' have an outnumbered defender trying to hold out against the attacker until their reserves come in.
** In-universe, this is usually the role of a world's [[HomeGuard Planetary Defense Corps]] in the event of enemy attack, to hold out until the Imperial Guard is mustered to come to its aid. If that's not enough, the Imperial Guard gets to hold the line until the Space Marines show up.
** Most engagements with the [[HordeOfAlienLocusts Tyranids]] seem to fall into this pattern, with a beleagured world trying to survive until a fleet of reinforcements arrives. Problem is, the Tyranids project a "Shadow in the Warp" that disrupts interstellar communication.

[[folder:VideoGames]]
* The climactic Battle of South Moundtop in ''VideoGame/{{SaGa Frontier 2}}'' is all about stalling for time. Unlike most of the other battlefield campaigns where there is either parity or conditions heavily in the players favor, this battle is against an army vastly your superior. Everything must go perfect for you to survive the necessary turns and your allies to arrive to finish the battle off screen.
* Several times in ''VideoGame/{{Warcraft}} III''. The final mission has your Night Elves and allied humans and orcs stalling Archimonde and the Burning Legion as they march on the World Tree, until Malfurion can gather enough Wisps to kill the demon lord when he tries to claim the tree's power.
** A BonusLevel of the ''Frozen Throne'' has you preventing the humans from destroying the portal the Blood Elves are escaping through in a TowerDefense scenario. Succeed and you'll earn an extra hero for the next level.
* The 3rd Terran mission in ''VideoGame/{{StarCraft|I}}'' involves this, where you must hold off the Zerg until rescue arrives.
** The ExpandedUniverse novel ''Speed of Darkness'' stars a group of Confederate Marines who fought a separate delaying action that apparently drew a sizable quantity of Zerg away from the PlayerCharacter. Though the fact that they had a [[spoiler:psychic beacon]] with them might have contributed.
** Played with in the final Protoss mission in ''VideoGame/StarcraftII: Wings of Liberty''. It takes place in the BadFuture, and defeat is unavoidable, you're simply trying to take as many Zerg with you. An optional objective plays it straight, in that other Protoss are trying to FlingALightIntoTheFuture, you need to hold out until they're done.
* Happens by event during some battles in ''VideoGame/HeartsOfIron II'' and ''III''. It slows the attacker down a bit and helps the defenders.
* The level "Revenge of the Empire" in ''VideoGame/RogueSquadron III: Rebel Strike''. Mirroring the Hoth example, Rogue Squadron is providing air cover to the evacuation of the base on Yavin IV.
* The entirety of ''VideoGame/MassEffect3'' is a delaying action meant to slow the Reaper assault long enough that the Crucible can be constructed.
* ''[[VideoGame/DawnOfWar Dawn of War: Winter Assault]]'' has a mission where the Imperial Guard agrees to ally with an Eldar force. Which of course triggers waves upon waves of orks to attack you culminating in a Squiggoth. Fortunately, the reinforcements you're waiting for include a [[TankGoodness Baneblade]].
* The opening of ''VideoGame/{{Steambirds}}'' includes the line "You cannot save the city, but you can stall the armada long enough for London's citizens to evacuate."

[[folder:Real Life]]
* Hundreds of real-life examples, including:
** Part of the Battle of Gettysburg - specifically Buford's cavalry holding Seminary Ridge.
** Part of Dunkirk.
** The battle of Thermopylae... which makes this one OlderThanFeudalism.
*** Twice at least. A second battle during WWII took place but it was a withdrawal instead of a sacrifice.
** Battle of Saragarhi. Twenty-one Sikh warriors fought to the last man to delay TEN THOUSAND Pashtun tribesman who were launching a raid into then British India, which would have undoubtedly meant the deaths of many civilians. Their Havildar (sergeant) put it to a vote, and they all voted to stay. They defended the mud-walled post with bolt-action rifles, and delayed the invaders long enough that they were met with British reinforcements and heavy artillery at their next obstacle. All 21 Sikhs were awarded the Indian Order of Merit, the the highest medal they could receive, the modern equivalents being the Param Vir Chakra or Victoria Cross (which existed then, but was restricted to British forces).
* This was a massive part of {{NATO}} plans for a WorldWarThree in Europe. The aim was to trade ground for time to allow US forces to arrive. One must feel sorry for the West Germans in all this...
** Though with WestGermany's insistence on "forward defense", that their country be defended right up to the border with EastGermany, it was really more like trading lives for NATO Army Groups to mobilize their corps and the mentioned REFORGER reinforcements to arrive.
* A day or two before [[RememberTheAlamo the battle of the Alamo]], the commanding officer received a dispatch stating that reinforcements were on their way to him. Some historians now guess that the desperate defense of the fort there was not intended as a last stand, so much as a delaying action in hope that those reinforcements would arrive.
* Also the basic concept behind "defence in depth", where an attacking force is delayed and bled by the delaying forces along with supporting artillery, air power, etc. until the attack the attack peters out and either retreats, or is vulnerable to a counter-attack.
