During the Galactic Civil War, a fleet was commanded by Admiral Harkov, an officer of the Imperial Navy. It took part in the Imperial intervention of the Sepan Civil War around 3 ABY. However, Harkov defected to the Alliance to Restore the Republic and later fought the Galactic Empire. Harkov was captured and taken prisoner by Darth Vader aboard his flagship, the Garret, and after an interrogation, was executed. His fleet continued fighting for the Alliance even after his death, but was mopped up by the Empire.
