The Imperial Fists keep up the pressure on the enemy at the Forge but their numbers dwindle.
The lower levels of the Basilica are taken and the forces of the enemy begin their evil ritual...
The Chaos Terminators keep up unrelenting fire on the Blood Angels veterans who are still left fighting.
The battlefield goes dark and foul magiks rack the air, emerging from the shadows Daemons stalk the land. A mighty Bloodthirster of Khorne closes on the Caldarius Regis but even as it does two more detachments of Fists land to take on the beast.
The artillery company collapses as men abandon their vehicles, driven mad by the sight of the creatures that close in around them.
The Guard at the Forge who had put up brave resistance, have no time to react to the Daemons that charge amongst them killing at will.
The last of the Devastators die under the blades of the World Eaters and Death Guard and the hab block belongs to Chaos.
The Bloodthirster's attack is unstoppable and despite its size the Caldarius Regis is destroyed as the Bloodthirster tears into its head, killing the crew. The Imperial Fists however, will not be denied and the Bloodthirster succumbs to their valiant assault.
For the Diem Aestus the fight is finally over, assaulted by both Plague Towers, its reactor goes critical. However it was not in vain as its opponents are both terribly damaged.
The Blood Angels realise there is no help coming and prepare to sell their lives dearly in the last fight at the Basilica.
The Basilica finally belongs to the forces of the Warmaster.
