Thassos Incident
The Thassos Incident occurred during the Horus Heresy in 13.M31, when a Dark Angels flotilla, taking part in the Legion's campaign of vengeance, was ambushed by a reaving Night Lords Warband.[1]
History
It began when the flotilla was sent to investigate rumors of an unidentified fleet lurking in the Segmentum Tempestus' isolated Thassos System. Upon arriving in the System, however, the Dark Angels were ambushed by the fleet, which was revealed to be a reaving Night Lords Warband. The Traitor Legion's attack, caused the Dark Angels flotilla to suffer severe losses, but the tide turned with the sudden arrival of an irregular Shattered Legions warfleet. Having emerged from the asteroid field around Thassos Secundus, their warships fell upon the Warband and prevented the Night Lords from landing a killing blow on the Dark Angels. The Warband then found themselves caught between the two Loyalist fleets and this caused the surviving Night Lords to hurriedly withdraw from the Thassos System. Once the battle was done, the Iron Hands, Raven Guard and Salamanders of the Shattered Legions warfleet, still sought a chance to avenge the terrible losses they suffered during the Dropsite Massacre. They were then given one by the Dark Angels' Primarch, Lion El'Jonson, and after the warfleet was resupplied, he tasked the Shattered Legions with scouring the nearby Systems of Warmaster Horus]' forces.[1]
