Clone troopers surrendering to an overwhelming number of droids
During the Clone Wars, Republic forces were present on a planet. Sometime between the battle of Bal'demnic and the invasion of Orto, the Separatists attacked the planet with a fleet of Providence-class carrier/destroyers. The Separatists then invaded the planet with B2 super battle droids and OG-9 homing spider droids. The battle ended when countless droids surrounded just a handful of clone troopers, forcing them to surrender.[1]
