Gereon Mission
The Gereon Mission is a Sabbat Worlds Crusade operation of the forty-first millennium, centred on the world of Gereon and linked to Gaunt’s Ghosts. It belongs to the Imperial effort to recover the Sabbat Worlds from the Archenemy, a war fought across a chain of contested systems under the strategic direction of Warmaster Macaroth. On the map, Gereon is the anchor for the operation; on the timeline, it sits within the crusade’s long campaigning period in the later forty-first millennium. Accounts of its precise date, and of its place relative to neighbouring campaigns, are recorded only in outline. The operation is associated with the Tanith First and Only under Colonel-Commissar Ibram Gaunt, a light infantry regiment that the crusade repeatedly used for reconnaissance, infiltration and special tasks behind enemy lines. Its causes are best understood from that pattern: the Crusade’s high command assigned missions of this kind where a conventional advance offered little prospect of success, or where the enemy’s dispositions had to be understood before a larger force was committed. Gaunt’s Ghosts are the principal Imperial participants attested; the opposing forces are the Chaos-aligned armies of the Sabbat Worlds theatre, and later tradition does not support a more detailed order of battle than that. The mission’s significance lies in what it adds to the record of the crusade rather than in a single decisive result. It links Gereon to the wider graph of Sabbat Worlds campaigns, to the regiment’s wartime service, and to the command structure that directed it, and it places the world among the theatres that shaped the Imperial advance. Readers should treat specific outcomes, casualty figures and later consequences as unconfirmed unless stated on the linked pages for Gereon, the Sabbat Worlds Crusade and the Tanith First and Only.
