The Battle of Beta IX was the battle to liberate Beta IX from Clark-loyalist Earth Alliance forces. Following the arrest of Captain John Sheridan by Clark's forces, Commander Susan Ivanova continued to lead the push towards Earth. They cornered several Omega class destroyers, including the EAS Damocles and EAS Orion, at Beta IX. They engaged the Earthforce vessels in response to their bombing of civilian targets. Commander Ivanova allowed the Clark-loyalists to take the first shot, then lead the charge to disable all ships.
