As a result, a general purge was organized by Lord Inquisitor Ghesmei Kysnaros.

Moreover, the Ordo Malleus was fearful that the taint of Chaos and corruption lingered within the surviving population. In the aftermath of the defeat of Angron on Armageddon, the Inquisition felt that the surviving Imperial Guard and civilian population could not be allowed to tell the tales of what they had seen to the larger Imperium, fearing the secrets of Chaos and the betrayal of the Primarchs would become known. Rather, the name was coined by some within the Grey Knights, who saw the deaths of their Grand Master and Battle Brothers as a mark of shame and regret. The term itself is not an official one, and indeed few in the Imperium are aware of the incident’s existence. Beginning as a purge by the Ordo Malleus against survivors of the conflict for fear of the lingering taint of Chaos, it escalated into skirmishes and eventual full battle with the Space Wolves. The Months of Shame is a term to refer to the immediate aftermath of the First War for Armageddon. Today Loremasters we speak of “The Months of Shame” – A secret war where the Grey Knights bit off much more than they could chew.
