Commander Corsa was an Imperial officer who served aboard the Imperial cruiser Valiant during the Galactic Civil War. In about 0 BBY, the Valiant, accompanied by a Star Destroyer and another Imperial cruiser, ambushed the YT-1300 light freighter Millennium Falcon in the Circarpous system. Corsa hailed the freighter and ordered the vessel to stand down and prepare to be boarded. However, the Falcon successfully evaded capture by the Imperials.
