The Indrigo Incident

The Indrigo Incident was the first encounter between Behemoth Splinter (Innsmouth) and Battlefleet Innsmouth in the Indrigo system of Innsmouth Sub-Sector.

Background to Events
in the aftermath of the destruction of Hive Fleet Behemoth at the Battle for Macragge in 745.M41, the Tyranid fleet was shattered into splinters that scattered in all directions. One splinter found its way across Ultramar space and entered Innsmouth Sector in 747.M41, arriving in the Indrigo System in the Innsmouth Sub-Sector.

The arrival of the Tyranids was first detected by orbital tracking stations around Indrigo IX, the outermost planet in the Indrigo system. This was met with surprise and alarm by the commanders of the local Imperial garrisons, particularly given the Indrigo system's proximity to the Innsmouth system and the de facto sectoral capital, Hive World Innsmouth. Nearby elements of Battlefleet Innsmouth were ordered to muster and eliminate the Tyranid threat before it had the chance to make landfall on Indrigo VI, the nearest populated planet in the splinter fleet's path.
