Caedem Crusade

The Caedem Crusade was a massive Imperial crusade undertaken by several Space Marine Chapters, spearheaded by the Hammer Guard Chapter, as well as several regiments of the Astra Militarum to bring illumination to the Caedem Sector which had fallen to both the Forces of Chaos and various Orks WAAAGHS!.

History
The first multi-chapter campaign involving the Hammer Guard was the Caedem Crusade, a multi-chapter and multi-regiment crusade to bring the Caedem Sector back to the Emperor's Light, and clear it of the numerous bands of Ork pirates and Chaos cults dotting the sector. Utilising his chapter's skill in siege warfare, the great Augustus Eudoxius deployed his chapter at the forefront of the crusade, cracking open the bastions of their heretical foes. Their contributions brought much honor to the chapter, and would allow them to take part in the glory of the final assault on Caedem Primus. This final assault would see them driving through a fortress held by a warband of elite Heretic Astartes and numerous cultists, all pledging their allegiance to Khorne. In the brutal close quarters combat that followed their penetration into the fortress, Dominum Custodem Euxodius led his Cataphractarii and Paladins into the main compound, where they witnessed the summoning of the bloodthirster Kale'malum. They dutifully battled this new threat, costing the lives of the Cataphractarii and of Euxodius himself, who sacrificed himself to banish the Daemon.
