Slenn

Slenn (d. 0 BBY) was the name of an Imperial Vice Admiral that served under the command of Darth Vader. Vader had placed Slenn in charge of a military excursion against the Rebel Alliance at the planet, Datar. Slenn mobilized his fleet too quickly and the Rebels were alerted to the attack ahead of time. This was a costly mistake that Slenn paid for with his life.
