Xamuel Lennox served in the Navy of the Galactic Empire. During the Battle of Hoth, Lennox was aboard the Imperial II-class Star Destroyer Tyrant, and a member of Darth Vader's personal Death Squadron. Whilst participating in the Battle of Hoth against the Rebel Alliance, Lennox attempted to intercept the first Rebel GR-75 medium transport to flee from Hoth. However, the Star Destroyer was disabled by several shots from the Rebel's v-150 ion cannon, commanded by Toryn Farr, leaving the ship to float helplessly in space.
