An attack was carried out on the Mid Rim moon of Phelzepham by Imperial forces led by Governor Ahr and Darth Vader which happened during the early days of the Galactic Empire. The aim was to eliminate insurgents. Darth Vader and a stormtrooper detachment were deployed to the surface in order to do this and were successful. Just when they had control of the moon, Ahr withdrew the stormtroopers though he kept Vader on the moon surface. Vader finished off the rest of the insurgents to the surprise of Ahr.
