Defence of Dalaham

The Defence of Dalaham was a xenocidal retribution campaign carried out by the zealous Castigators Space Marine Chapter against an Aeldari strike force from the war-mongering Biel-Tan Craftworld that assaulted the Imperial world of Dalaham.

History
The capital city of Syrrios, Dalaham, was assaulted by the vile Eldar for unknown reasons. The Aeldari had appeared from an unknown webway gate, with their own agenda in mind. With ruthless speed and efficiency, the assembled warhost of Craftworld Biel-Tan - the so-called Swordwind - descended upon the Castigators. Although the Aeldari loss of life was considerable, they managed to force the Castigators back. The 8th Assault Company, under the newly promoted Captain Tigris, assaulted the Aeldari in a two-pronged assault, crushing the vile xenos between their two forces. The planet was free from their foul taint within the month.
