During the operation against Task Force Vengeance in the Airam sector, Oro Squadron was assigned to escort a convoy of Rebel ships bearing the needed supplies and personnel to construct a shipyard in the area. However, the Empire had learned of the convoy and readied a trap in the Rocrin system. Oro Squadron was torn from hyperspace along with the rest of the convoy by Interdictor cruiser Compellor. Oro, seeking to defend its charges, engaged incoming Imperial bombers. Despite reinforcements from the X-wings of Ulan Squadron, the whole squadron was wiped out by Imperial forces.
