Mordecai - Battle for Menoria Hive

Having gained a foothold on Mordecai Primaris in 06.023M42 the Imperium had taken their time to build up supplies before breaking out of their bridgehead. General Kutuzov was planning a regular ground offensive from the North Averbrike hive sprawl, using mechanised units to take swathes of territory before attempting to take another city, but in 09.023M42 the Angels of Vengeance, a successor chapter to the Dark Angels, offered Imperial command an alternative plan.

Using their elite strike forces the astartes promoted the idea of a direct assault on Menoria hive. If successful the capture of this second strategic location relatively close to the existing bridgehead offered the opportunity to attack any chaos forces in the plains from two directions, while doubling the supply logistics if the city could be taken intact. The operation was high risk, as a direct assault on Menoria would likely result in direct intervention from the Thousand Sons from Astralis, but general Kutuzov was convinced by the arguments made by the Angels' chapter master.

The assault on Menoria started with a drop directly into the chaos held hive sprawl, and it wasn't long before Magnus the Red himself intervened, a large force of Thousand Sons arriving to defend the city. There would be no retreat from this battle, either the Angel's of Vengeance would take the city or its space port, or die trying.

The battle for Menoria was ferocious, with the Angels of Vengeance deploying their most elite forces including their Chapter Master, facing off against the strongest forces the Thousands sons could field, including a daemonic apparition of Magnus himself. The deathwing knights held the line against a storm of sorcery and daemonic energies, and after several hours of brutal combat, the Angels of Vengeance had broken the back of the chaos resistance in the hive, destroying the Thousand Sons forces and sending Magnus and his chief sorcerer back to the warp. The Imperium now had a bridgehead at Menoria, and efforts now turned to consolidating the separate areas of imperial control and joining them up to move forward across the rest of Mordecai Primaris.
