Changes

The battle lasted another three weeks. The Imperial Fists' ammunition was expended and they fought individually in half flooded trenches with their combat knives,^1b refusing to submit while they dug into the mud and used their fallen battle-brothers for cover.^3b Dorn personally turned back a number of attacks. The Legion's captains pleaded with their primarch to organize a breakout and retreat, but Dorn refused. Ever loyal, the Imperial Fists resigned to die fighting alongside their lord if necessary.^3b

After three weeks and six days, [[Ultramarines]] intervened, driving off the [[Iron Warriors]]. Unable to defeat both Legions combined, [[Perturabo]] concentrated his forces on denying the [[Imperial Fists]] withdraw and disrupting their ability to collect their dead and wounded, ultimately leaving 400 battle-brothers on the surface of Sebastus IV.^3b
