Traitor Imperial Guardsmen move towards the bombed out ruins of Kasr Gerh.
To the surprise of the Imperial Command, the Dark Angels defenders were lead by Belial and Sammael the masters of the Deathwing and Ravenwing.
Sammael and the Ravenwing move swiftly to outflank the Chaos forces.
The Dark Angels engaged the rebel forces in fierce city fighting. As the battle wore on, the traitor guardsmen found themselves unable to match the Deathwing Terminators in close combat. Overwhelmed, the rebels were forced to withdraw from the mission.
Having successfully repelled the traitor guardsmen, the Dark Angels were ordered by Imperial Command to support the Mechanicum Marines and Sisters of Battle. In a bizarre turn of events, Belial refused the request and teleported back to orbit in the Sword of Redemption. Despite their valiant efforts, the remaining Imperial forces were defeated by the Chaos Space marines. Kasr Gerh fell into the hands of the Chaos invaders.
