During the Crusade, the 413th Fleet was called on to conquer the [[human]] worlds of the [[Gardinaal System]], which were resisting [[compliance]] with the [[Imperium]]. Although the Fleet's initial actions were successful, blockading and isolating the outer worlds of the [[system]] before neutralising their threat, the invasion of [[Gardinaal Prime]] met with disastrous failure. The Fleet's ground forces suffered heavy losses - the [[Imperial Army ]] contingent alone took 500,000 casualties. Although the Imperials maintained void superiority, they were unable to prosecute another landing and were forced to call for aid; this ended up taking the form of a combined force from the [[Iron Hands]] and [[Emperor's Children]] [[Space Marine Legion|Legions]] led in person by [[Ferrus Manus]].{{Fn|1}}
