The '''Second War for Armageddon''' is the second best known of the [[Armageddon Wars|three wars of the system]]. It took place on the [[Hive World]] of [[Armageddon]] between the mighty [[Ork]] [[Warboss]] [[Ghazghkull Mag Uruk Thraka]] and the forces of the [[Imperium]] and included [[regiment]]s of the [[Imperial Guard]] and [[Space Marines]] of the [[Blood Angels]], [[Salamanders]] and [[Ultramarines]] [[Chapter]]s, along with a large [[Squat]] army. It would see the planet being swarmed with green-skinned Orks of five different tribes. The main war lasted for two years, but the actual combat continued for the next twenty years, a colossal effort for just one planet.
