Mordecai Tersius: Cybixx charges north

Having secured his flank in the early skirmishes on the plains north of the Vaylin mountains Cybixx began his main assault on Mt. Harender. The ruined city would need to be secured before he moved north to capture the Mechanicum Industria. For this operation the arch magos threw in his elite constructs as well as his regular Mechanicum troops. 

The initial resistance comprised of Librian infantry garrisoning the city. These units were rapidly swept away before the traitors’ advance with almost 100% casualties. Infantry alone were no match for the weapons of the Arch heretek. 

Colonel Dempsey rapidly threw in his armoured reserves as it became clear this was a major attack, but the Leman Rudd elements arrived peacemeal and the inexperienced tank crews struggled to hit their targets. The artillery were more effective, but were unable to stop the Ironstriders’ assault, nor meaningfully damage Cybixx’s robot constructs or heavy tank elements. 

The ironstriders were joined by more elite forces teleporting into the battle, and together they crashed into the imperial artillery. The subsequent melee resulted in many of the Mechanicum walkers piercing the imperial artillery with their lances, catastrophically detonating their stored ammunition. The resulting series of explosion wiped out the imperial guns but took a terrible toll on the assaulting forces, totally eliminating some of Cybixx’s best troops and weakening the attack. Dempsey’s hellhounds then arrived, obliterating the remaining walkers with their Prometheum flame cannons. The chaos light infantry also suffered at the hands of the flame tanks, but the dreadnought construct, code named “Telemon” by the imperial forces made short work of them. Cybixx eventually lost his heavy tanks to the remaining imperium Leman Russ, but this too succumbed to the Telemon. 

Cybixx’s forces had taken moderate casualties, but not quite enough to stop the advanced. Dempsey meanwhile had lost all his armoured units and was powerless to stop the chaos advance. Kutuzov ordered his armies north to prevent being encircled, and by 0607.019M42 the Magos Dominus had secured the Mechanicum complex and began harvesting its dark secrets.
