Changes

With the fall of Acheron to the Orks by the treachery of [[Herman von Strab]], Imperial forces were pushed on to the defensive and forced to maintain a perimiter. Weeks later Space Marine detachments were finally brought in and landed by [[Thunderhawks]]. They succeeded in recapturing several areas around the main Hive, including Acheron Bridge and Von Strab's Memorial Arch however the Hemlock Cordon was overrun by the Orks of the [[Blackskulls Tribe]] from the Hemlock River Tunnel. This forced the Imperial armies to attack the Hive itself as their escape route had been cut off and Ork reinforcements were rapidly approaching in the form of [[Kroksnik's Deth Traks]].

In the Ash Wastes around the Hive, [[Cadian Shock Troops|Cadian]] and [[Savlar Chem Dogs|Savlar]] forces were trying to blockade any Ork reinforcements. They were at last reinforced by [[Warlord Titans|Warlord]] and [[Reaver Titans]]. This effectively cleared the wastes of the Orks back to their own drop sites where two of three [[Roks]] had already been destroyed by the [[Salamanders]], supported by [[Legio Metalica]]. The third fortress remains whole and intact and a dangerous threat to the area.
