Burning of Salile

The Burning of Salile was an Imperial campaign involving the Astral Serpents Space Marine Chapter upon the Imperial world of Salile, which they defending from a massive Ork WAAAGH! in the latter centuries of M36. Faced with an overwhelming tide of greenskin forces which seemed to be drawn to the brutal conflict on Salile, and with three whole companies nearly destroyed, the Chapter was forced to enact Exterminatus upon the doomed world to prevent it from falling into the hands of the vile Orks.

History
upon the world of Salile an Ork WAAAGH! landed on the planet using old derelict spaceships. They landed upon the world and began to kill its populace and destroy its cities, soon after the Astral Serpents rallied their allies and moved on Salile to retake it. The fighting was fierce and hard fought and in the hive city of Vestral the 2nd, 6th, and 7th companies were practicality destroyed when the orks made the city's power plant go critical and explode. With losses mounting, and three whole companies practically destroyed, the Chapter ordered that Exterminatus be used upon Salile.
