====First Battle of Struthis and Battle for Hauser====
The Pacificus Campaign began with the securing of two vital worlds: the forgeworld Hauser and the armoury world Struthis. In charge of seizing Struthis was the 99th Army commanded still by Grand Marshal Judas Ranc, while the conquest of Hauser was left to the Mechanicum of the Al-Sherar Sector and the Ciban Chasseurs. Initial reports claimed the warehouses of Struthis were lightly defended, but upon arrival Ranc quickly realized their intelligence was trickery. The planet was not only heavily defended, but its reinforcements were renegade Markians of the 56th Army, thought lost in battle at the Heresy's start. The shock of meeting their former comrades in battle struck the 99th's morale a blow as devastating as the defensive artillery the traitors sent their way, and the invasion quickly reached a standstill. Rather than remaining in this deadlock, Ranc instead withdrew the army from Struthis to join the Cibanese on Hauser, where the campaign was similarly bogged down by surprises.

On Hauser, the advance had slowed to a crawl with the intervention of Legio Digitus, the "Finger of God". These ancient titans wrought havoc on the Imperial forces, even with two legions facing them. Such was their strength that before the end of the battle Legio Cataegis had suffered catastrophic damage and was unavailable for the rest of the Heresy. The 99th's entry into the battle did little to change the course; in the end Legio Digitus was defeated by Legio Antsar in a grand exchange of superheavy fire in Vinagio Canyon. Following the destruction of the traitor titans the 99th worked with the remaining Chasseurs and skitarii to clean out the forges of the world and reclaim the world for the Imperium, thus acquiring the first world needed for the Pacificus Campaign.
