During the Horus Heresy, Krade was the site of one of many defensive battles waged by the Iron Warriors in their attempts to the Ultramarines from advancing to Terra and reaching Horus' rear. After months of fighting led by Perturabo himself, neither side was gaining ground but the loyalists, bolstered by experienced Imperial Army veterans as well as newly arriving Ultramarines, were beginning to gain the initiative. It was at this point that Horus' emissary Argonis arrived, demanding that Perturabo abandon the war on Krade in order to find Angron and bring him to the muster at Ullanor. Despite the losses the Iron Warriors had incurred defending Krade, Perturabo withdrew the majority of his forces and abandoned the effort. Soltarn Vull Bronn was left in command of the remaining Iron Warriors garrison.
