Changes

The Grey Knights dispatched one hundred and nine{{Fn|3a}} [[Grey Knight Terminator Squad|Terminator Assault Marines]] who attacked Angron directly, along with the [[Cruor Praetoria]], his bodyguard of a dozen [[Bloodthirster|Bloodthirsters]], by teleporting into the center of the daemon army. At the same time, the Space Wolves led a massive Imperial counter-attack. Initially Angron and his escorts decimated the Grey Knights, the Primarch wiping out five Grey Knights Terminators with a single stroke of his [[Black Blade]]. However thanks to the psychic might of the young recruit [[Hyperion]], the Black Blade was shattered and the Grey Knights were now at a significant advantage. Soon after, Brother-Captain [[Taremar Aurellian]] was killed while personally banishing Angron back to the warp for a hundred years and a day. The loss of their leader, coupled with the surprise assault from the remaining imperial forces, led to the near-complete annihilation of the chaos forces on Armageddon. Though the final battle was a major Imperial Victory, only thirteen Grey Knights survived{{Fn|3b}}

*{{Main|Months of Shame}}

Although they had won, the victorious soldiers of Armageddon were doomed. They had gained knowledge of the existence of Chaos, and been exposed to its corruption. The Inquisition had all of the people who fought on the planet, except for the Space Marines, sterilized and placed in work camps. Armageddon was re-colonized by people from other regions of space with no knowledge of the war. The Inquisition and Grey Knights went on to purge [[Imperial Navy]] and [[Adeptus Mechanicus]] ships orbiting the planet and [[Grey Knights Strike Cruiser]]s destroyed Imperial Guard troop transports that were departing.{{Fn|3c}} Three entire nearby worlds were put to the sword to silence the populous when they had heard of the exploits of [[Stormtroopers]] that were at the battle of Helsreach Hive. The purges claimed several billion souls.{{Fn|4}} Logan Grimnar battled long and hard to prevent this and even attempted to have his fleet escort ships of survivors away from the Inquisition, but after an attack by the Ordo Malleus and Grey Knights he failed and has never forgiven the Inquisition for doing what he saw as a betrayal of the people who had fought honorably for their homes and for the Imperium. Moreover the worlds that came into contact with the survivors escorted by the Space Wolves where also put to [[Exterminatus]], resulting the destruction of the [[Adeptus Astra Telepathica]] station [[Ralas Meridian]], the worlds of [[Jendara Quintus]] and [[Tybuilt]], and the [[Adeptus Mechanicus]] outpost of [[Priam Novus]].{{Fn|3d}}
