Coen was a CR90 corvette belonging to the Rebel Alliance during the Galactic Civil War. Coen was assigned to the Rebel hospital as protection for the Rebels who were wounded during the evacuation of Hoth. However, while Tomaas Azzameen, piloting the Vasudra, was delivering bacta to the Rebels, The Star Destroyer Corrupter and a pair of Lancer-class frigates, the Cascade and the Blue Hawk, dropped out of hyperspace and began a bombardment of the hospital, executed by TIE/sa bombers.
