Despite being forced into exile after the end of the Federated Suns civil war in 2537, Cassandra Varney and her son Roger still possessed some loyal supporters. In 2565, Roger Varney, aided by a small Capellan squadron, crossed the border and attempted to rally supporters on Carmacks. Though he raised a fairly large militia force, they were no match for Davion regulars, particularly since the Capellan WarShips were annihilated in the Battle of Kigamboni in late 2565.
This halted Roger's advance on new Syrtis, where he had hoped to gain massive support from long-time Varney supporters. The Davion 'Mechs of the Eighth Syrtis Fusiliers caught him in a retreat to the frontier, destroying Varney's force almost to a man. Though Roger escaped to keep his cause alive in exile amongst the Capellans, his military support was gone.
