Horus ordered his army to push on and had the attack on the outer walls of the [[Imperial Palace]] be spearheaded by the [[Legio Mortis|Death's Head]] Titan Legion. Losing five Titans within minutes to entrenched loyalist defenses, the traitor forces would not relent and kept hammering away at the palace walls. A counterattack against the Chaos horde's flanks by loyalist titans failed, though the [[White Scars]] took advantage of the confusion it caused to sweep down at the traitor forces rear columns and wreak havoc.{{Fn|2}} The Siege of the Imperial Palace soon ground on for many days, with the two primary attacks during this time being made by Angron and his World Eaters supported by [[Daemon Engines]] in one sector and the [[Legio Mortis]] in the other.{{Fn|1c}} Under a the vicious combined attack by the World Eaters and Legio Mortis, major breaches were made at the Mercury and Exultant Wall zones. The way to the [[Sanctum Imperialis]] was now clear and the loyalist defenders seemed doomed, with many seeing the battle now as a suicidal final stand rather than one in which they could emerge victorious.{{Fn|20a}}
