Battle of Onderon
this was the name used by historians to describe the struggle between the ancient Jedi Knights and the Sith warriors who controlled the planet Onderon, during the Great Sith War. The Sith Lords ordered the Mandalorians to descend on Onderon. Mandalore agreed to the mission, and attacked Iziz. However, his forces were overcome Onderon during a pass of the Dxun moon, and fled to the moon for refuge.
