The Assault on Moros occurred in 364.M39, when the lynchpin bastion of Fort Moros fell to a Chaos-inspired rebellion and the 23rd Elysian Drop Troops Regiment was tasked with recapturing it. The Elysians deployed directly into the sprawling fortification and discovered that the fort had become the domain of madmen and fiends who soon turned upon them, causing the beleaguered regiment to immediately send an astro-telepathic call for aid. In response, the 5th Company of the Death Strike Chapter diverted from its current mission to relive the Elysians and crush the heart of the uprising.[1]
The 23rd Elysian Drop Troops were later awarded a regimental unit citation for their part in the assault on Fort Moros.[2]
