Dark Angels retake Abrax mines on the Eastern Front

While the main action on Mordecai Secundus was taking place further south, the Dark Angels decided of their own volition to sort out the Eastern Front. It had only been mere weeks since the forces of chaos had overrun part of the Abrax mines complex, and while the chaos forces on this front did not pose a significant risk to Fort Vengeance or imperial HQ (thanks largely to the deep imperial fortifications in the area), the loss of the mining complex was of strategic significance.

The Dark Angels drew up a focussed and limited plan to retake the mines, launching their assault simultaneously with operation Sarkar to minimise the threat of rapid redeployment by the enemy. Using their most elite troops, including their Deathwing and Ravenwing elements, the loyalist astartes were able to grab key objectives then weather the counter attack by the Thousand Sons. Although only a "side show" to operation Sarkar, the reclamation of the Abrax mines was nonetheless a welcome boost for the imperial campaign on the planet.
