It was part of the [[Retribution Fleet]] sent by the [[Primarch]] [[Rogal Dorn]] to confront [[Horus]], when the [[Horus Heresy|Heresy]] began. However, due to severe [[Warp Storms]], the Fleet was left stranded in the [[Phall System]] and the ''Devastation'' later fought the [[Iron Warriors]] Legion, during the [[Battle of Phall]]. However the Fleet's [[Space Marine Captain|Captain]], [[Alexis Polux]], later gave the order to retreat back to [[Terra]] before the Fleet became trapped due to the Warp Storms. The ''Devastation'' and its fellow [[Lunar Class Cruiser]]s ''[[Ramses]]'' and ''[[Pylades]]'', were unable to escape in time and were left behind by the Retribution Fleet. Now surrounded by nothing but the Iron Warriors' fleet and the wrecks of the two Legions' warships, the three Cruisers attempted to escape to the nearby [[Tarkovsky Epsilon System]]. The Iron Warrior's [[Primarch]] [[Perturabo]], who was still angered by his failure to destroy the Retribution Fleet, refused to let the Cruisers escape and pursued them aboard his flagship , the ''[[Iron Blood]]''. As the Cruisers raced to safety, their crews devised a plan which would see the ''Pylades'' and ''Ramses'' escape into the asteroid field surrounding the gas giant [[Tarkovsky II]]. It was hoped that the ''Iron Blood '' would pursue them into it and allow the ''Devastation'' to launch a surprise attack on the much larger warship. This plan would fail, though, as the ''Iron Blood '' reached the ''Pylades'' and ''Ramses'' shortly after they neared the gas giant. The ''Iron Blood '' then quickly destroyed the ''Pylades'' and ''Ramses''; leaving the ''Devastation's '' crew with the choice of trying to escape or launching a suicidal attack on the ''Iron Blood''. The order to attack the Iron WarriorWarriors's flagship was given, but Perturabo refused to have the ''Iron Blood '' fire upon the ''Devastation''. He had no respect for such weak -willed tactics and Perturabo decided to show his disdain by having the ''Iron Blood '' ram the ''Devastation '' instead. The Cruiser had no chance against the much larger warship and it was utterly obliterated by the impact.{{Fn|1}}
