Battle of Ceres

The Battle of Ceres was fought between Koslovic and UNSC forces from September to October in 2164. Koslovic leadership correctly identified the shipyards and factories of Ceres as the principal supplier of Frieden weapons and ships in the belt, a fact which would remain unknown to the UNSC until after the Siege of Ceres ended in 2168. The Koslovic assault ultimately failed and the majority of pro-Koslovic organizations and sympathizers on Ceres were drastically reduced as a result. Ceres remained uncontested until July 2167, when Frieden forces successfully occupied the colony and held it for more than a year.
