"This was a war where there could be no honourable peace. It was destroy or be destroyed. For a moment all was silence, then Angron strode forth. In his brazen voice he demanded that the loyalists surrender. He told them that their cause was hopeless, as they faced a foe which could not be defeated. They were cut off, outnumbered, and defending a ruler too weak to be worthy of their loyalty. In that moment the men on the walls felt their resolve weaken. Looking at the transformed face of the Primarch who had once been one of the Emperor's finest warriors, they saw an invincible, relentless foe backed by a numberless horde and all the daemonic might of Chaos.

There was a clamour on the walls as Sanguinius and the Blood Angels arrived. Standing on the wall, the angel-winged Primarch glared on Angron with angry contempt. For long moments their gazes locked, each Primarch seemed to be measuring the other, searching for chinks in the armour, for any sign of weakness and lack of resolve. Who knows what they saw there? Perhaps they communicated telepathically, brother Primarch to brother Primarch. The truth will never be known. Eventually Angron turned and walked back to his lines. He told his troops that there would be no surrender; they should kill everyone they found within the palace. No stone should be left upon stone. "
