Editing War of Beasts (section)

===Retaking the Hoist===
To deal with their water problem, the Imperials set out to recapture the Omnissian Hoist from the Genestealers. The cults had already been weakened by a prior skirmish with the Magma Hounds warband, allowing a combined force of Iron Hands and Skitarii to push through the alien hordes.

The Grandsire Wurm itself was forced to lead the counter-attack, eventually sealing itself into the hoist's main control center in a final effort to deny it to the AdMech. But it hadn't counted on the Onager Dunecrawlers that had crawled up the structure, and it was forced to retreat after being wounded. After that, the Dunecrawlers were able to mop up the remaining Purestrains without difficulty.
