When the CSCN Landed on Eberus, they were confronted on all sides from units from across the planets, and donated units from other planets and solar systems entirely. Militia and Military. The operation ended quickly and in catastrophe for the CSCN, leading to the absolute destruction of a huge percentage of the Federal military's armed ground forces. Having dug little fortifications and being kept on the move constantly, when the Pact forces in the initial defense rapidly changed direction and turned on the Confederates, they had no fortified strong positions to go to, and the overwhelming amount of militia national guard, and regulars coming out of hidden positions or disguised as civilians, left them little other option than surrender or death.
