The scourging of Hogan's Fall

While the assault on Trian raged, there was fighting on two other worlds within the Vastrid subsector. On 0311.011M42 the Dark Eldar of the Shattered Silence fell upon the Imperial base on Hogan's fall. The base had only recently been wrestled back from the Orks, and the Imperial Guard at the base were entirely wiped out or captured before the Grey Knights, using the world as their base of operations within the subsector, could counter the alien raid.

The Grey Knights moved quickly to stop the Dark Eldar from entirely destroying the base, but the Shattered Silence brought murderous firepower to bear on the small Imperial force. Before long the Grey Knights were in retreat and were forced to ask for assistance.

The Dark Angels responded to the call but deployed straight into a Dark Eldar ambush. They lost many brave astartes warriors before aborting their mission, leaving the Grey Knights to fight off the aliens alone. Unlike their other raids, the Shattered Silence continued their pursuit against the Grey Knights until they were forced to completely abandon the world. The Dark Eldar Kabal had already taken a huge haul of slaves, so this action perplexed the Imperial forces and drew the attention of Inquisitor Huron, who in response moved his base of operations to the subsector.

By 1011.011M42 the Grey Knights had evacuated Hogan's Fall, leaving any remaining Imperial citizens, military or civilian, to an unpleasant fate at the hands of the Dark Eldar. Hogan's Fall had been destroyed as an Imperial base, at least for the time being.
