Evacuation of Septem XI

The Evacuation of Septem XI was an Imperial evacuation operation carried out by the 501st Cordanian MIR upon the Imperial world of Septem XI that had become plagued by the Zombie Plague that threatened to overwhelm the entire planet of Septem XI. Though the Imperial forces were forced to enact Exterminatus upon the doomed word, in order to deny the planet to the Plague God, the 501st managed to successfully evacuate all uninfected survivors from the planet.

History
The planet of Septem XI comes under a plague unleashed by the Chaos God Nurgle, releasing the dreadful Zombie Plague upon the doomed world. This plague quickly claimed most of the hive cities on the planet. Septem XI was soon deemed lost to the Imperium. During the final days of the planet, the 501st sent out 5 full platoons of soldiers along with their support elements of heavy armour and mechanised vehicles. They managed to hold out against the hordes of zombies and managed to evacuate the last of the uninfected survivors off-world before the wall defences finally fell. The regiment also managed to get most of the last remaining armed forces out before the seal of Exterminatus was enacted.

The regiment suffered the loss of six full companies, with one company whittled down to only a squad of survivors. Following this campaign it took nearly two-and-a-half years to re-constitute their ranks, since they suffered the loss of some of their finest platoons of the 501st.
