First War for Armageddon - Origins of Conflict: The first indication that there were going to be problems with the Inquisition's post-war plans was revealed solar months before the end of the war, in the first meeting of Logan Grimnar with the newly arrived Inquisitorial task force. Although he knew that the Inquisition would have to suppress the truth of the war after it was over, Grimnar made clear that he did not wish it to carry out the usual suppression campaign. As there was already mistrust and suspicion of the Space Wolves within the Imperial hierarchy over past disputes and the Space Wolves' habit of disregarding Imperial authority, Grimnar's demand seemed either naive or an excuse for a fight, while his manner was condescending towards the Inquisitors.However, in truth Grimnar was genuinely sympathetic to the human element on Armageddon, and questioned the wisdom of saving a planet if its inhabitants and defenders would then have to be "processed" by the Inquisition for the sin of knowing about the existence of Chaos or the secret Imperial organisations arrayed against it. Grimnar had specifically structured the planet's defence and use of the Grey Knights in order to minimise the chances of the remaining civilian population accidentally finding out the truth behind the war and the nature of the daemonic. This strategy to protect the civilians guaranteed "catastrophic casualties" amongst the defenders, both Astartes and mortal humans alike.The Inquisition was not moved, nor did it deviate from its position that it was by law and the Emperor's decree the ultimate arbiter of what was right for the Imperium and Mankind. The truth of Chaos and the existence of the daemonic had to be contained and prevented from spreading into the wider galaxy where it would cause only more suffering. It was far better to sacrifice millions than have to exterminate billions, as had happened in the aftermath of the Horus Heresy.In practical terms, it made sense to the Inquisition to contain the situation on the planet itself, as this would affect a relatively small number of Imperial citizens compared to the damage control that would have to take place if any escaped the planet to spread Chaos corruption elsewhere. The Armageddon Containment was the result of a majority vote by a conclave of the Inquisitors on duty at the planet, and would entail several directives, including the sterilisation (to prevent Chaos mutations from being passed on) and quarantine of the entire surviving civilian population of Armageddon in Adeptus Arbites work-camps scattered across the galaxy.This was decided even though that population was generally considered untainted, and had no knowledge of the truths behind the war. A similar fate, or even outright liquidation, awaited the human defenders of the Armageddon Steel Legion and the Armageddon Planetary Defence Forces, who had valiantly faced the Chaos hordes that had invaded the Hive World. The use of Exterminatus against the world in order to keep the secret of Chaos' existence was not an option: the industrial capacity of the planet was too important to the Imperium and the defence of the Segmentum Solar to be destroyed.Inquisitor Lord Ghesmei Kysnaros, as the ranking Inquisitor present, had overall command of the Armageddon Containment mission from his flagship, the commandeered Imperial Navy Battlecruiser Corel's Hope. His attitude to the Armageddon purge was typical of the Inquisition's pragmatic and calculating position: better to sterilise or kill millions on suspicions of Chaos taint, than to have to eventually kill billions in order to prevent the possibility of taint from spreading.As the war was winding down, over the objections of Grimnar (which were broadcast to all Imperial forces), he ordered the start of the first phase of the containment: Inquisitorial Storm Troopers began to evacuate the remaining hive cities and to herd the population into camps for "vaccinations" -- in reality, sterilisation by injection. The civilians were told that the evacuation was a "temporary security measure." The planet's human defenders, including at least one million Imperial Guardsmen who arrived for mop-up operations after Angron had been banished, were ordered into barracks pending their own "processing."The Space Wolves on the surface engaged in only minor disruptions -- as they were clearly overmatched on the ground by the more than 100,000 Inquisitorial Storm Troopers and other Inquisition forces. However, they had the advantage in space, with 16 starships present to the Inquisition's 12. Additionally the Space Wolves' ships were generally bigger, better armoured, and better armed. Grimnar's plan was to help the human defenders and civilians of Armageddon escape the Inquisition by making sure their transports safely jumped into the Warp at the first opportunity. Twenty such transports were already waiting for their human cargoes above the planet.Soon, the first such transport, the Trident of Ilmatha, loaded mostly with defenders but also with civilians, was en route to the Armageddon System's Warp jump-point, escorted by the Space Wolves frigate Runefyre. The ship never made the Warp jump, as its Warp-Drive was disabled by the Grey Knights Frigate Karabela which then proceeded to scuttle the ship; there were no survivors among the Trident's 400,000 passengers. These were the first shots and the first casualties of the internecine war that followed. For their part, the Space Wolves did not retaliate against the firing vessel. Grimnar wanted to see whether the Inquisition would actually go ahead with its plans -- one of the many miscalculations that occured on both sides.Following this episode, Grimnar ordered all the remaining loaded transports to make orbit at the same time, each protected by Space Wolves vessels who put themselves in the Inquisition ships' line of fire with orders not to fire back under any circumstance. Using this strategy, at least some of the transports would safely make it to the system's Mandeville Points. Kysnaros, who had tried to reason with Grimnar in an exchange that descended into insults and terrible threats, countered by ordering his fleet to fire at the interfering Space Wolves Escorts, as well as targeting the troop transports.However, as Inquisitorial ships opened fire and before Kysnaros' order could be completed, Space Wolves reinforcements lead by the Battle Barge Gylfarheim translated into the system, presenting the Inquisition with overwhelming naval superiority. A triumphant Grimnar then bade Kysnaros to call off the attack and the chase, which the Inquisitor Lord had no option but to do. The majority of the troop transports carrying Armageddon's survivors had survived the brief engagement. Escorted by Space Wolves vessels, they then safely translated into the Warp.
