Corinth Crusade

The Corinth Crusade was one of the most famous Space Marine actions of the mid-41st Millennium. Conceived and led by the legendary Chapter Master of the Ultramarines Marneus Calgar, the Crusade comprised the combined forces of Ultramarines, Angels of Absolution, Lamenters, Silver Skulls, Scythes of the Emperor and the Marines Errant as well as over 50 Imperial Guard regiments against the massive power of Waaagh! Skargor, which had its heart in the seething morass of the Corinth System deep within the Ork empire of Charadon. During the highly successful Crusade, the Marines Errant were singled out for particular honour, both because of a series of closely fought boarding actions against Skargor's fleet of Terror ships, and for the rescue at great risk to themselves of the embattled Ultramarines 3rd Company.

The Ultramarines had become trapped on the dust moon of Lhak after the destruction of their strike cruisers above the planetoid, and fighting off fearful odds the Marines Errant battered their way through the encircling horde of freebooters and ramships to extract their progenitor-kin from the surface. In recognition of this deed the Marines Errant one of the Ultramarines' own sacred relic blades as a sign of the mutually shed blood of the two Chapters in gratitude. The successes of the Corinth Crusade not only beheaded and scattered Waaagh! Skargor, but also delayed any further major Ork incursions from the Charadon region for more than 30 years.
