The 23rd Cadian was stationed in the Cobalt Valley where an extremely important stretch of road stretched for several hundred leagues in each direction. This was the sight of a major battle between the 23rd Cadian and the Alpha Legion. Though outmanned and outgunned, the "Emperor's Hounds" used their superior knowledge of the terrain and their limited armour elements to their advantage. After three weeks of valiant struggle, additional Imperial Guard regiments from Cadia, Gorin V and Linnerberg arrived in the Cobalt Valley and found a blasted wasteland. Nearly the entirety of the "Emperor's Hounds" had been killed, and over three quarters of those remaining were badly wounded. Their regimental commander, Colonel Lean, was awarded the Terran Laurel for his part in the battle and the 23rd Cadian's survivors were relieved from active service as a reward, allowed to accompany the Adeptus Mechanicus' Explorator fleets and colonise a new world.

The Ecclesiarchy world of Heletine had come under assault from several warbands aligned to the Black Legion, chief amongst them the Children of Torment which saught to destroy Imperiale relics and thus weaken the populations faith. As a result, desertion and corruption amongst the Heletine militia has reached unprecedented proportions, Colonel Redgage of the Cadian 81st resulting in the installment of several dozen firing squads on a daily basis, even though officially none of the 81st was swayed into worship of the Chaos Gods. True heroism and sacrifices, the 81st Cadian successfully stalled the enemy advance until reiforcements could be brought in.

With over half of the Khai-Zan PDF on leave, the Agri-World quickly found itself quickly beset on all sides by the forces of Chaos. The cultists utilised summoned daemons but, due to the world's distance from the Eye of Terror and the lack of devotion to the Chaos Gods from the Night Lords, the actual number of summonings proved very small. The Night Lords' Exalted Champion Gorsameth lead his troops in a clash against the men of the 122nd Cadian Shock Troopers, under the command of Captain Fane, who sought to defend the Imperial city of Vogen.

Soon after their arrival in the war zone, they were placed under the command of Grand Inquisitor Belerophus Hotha to aid him in his investigation of an unknown Tyranid Hive Fleet. During three months of continual fighting, the 411th suffered heavy casualties in pursuit of this goal. Colonel Frohlof noted in his personal log the suspicious behaviour of the war zone's supreme commander Lord Marshal Graf Harazahn, of the Vostroyan Firstborn, who had a tendency to supply the 411th only when the situation became strategically critical, and even then only at the last minute. The last orders received by the 411th Cadian were directed by Grand Inquisitor Hotha and their position in Combat Zone Hydra located deep in the ash wastes of Medusa V.
