Battle of Ilum

The Battle of Ilum took place early on during the Clone Wars when Luminara Unduli and Barriss Offee were at the sacred Jedi crystal caves on the snow planet of Ilum when they were attacked by chameleon droids, sent by Dooku to destroy the temple. Jedi Master Yoda learned of this attack while he was with Padmé Amidala. He suggested they take a slight detour to Ilum to investigate. Once they landed, Yoda proceeded on foot towards the temple alone.

The Grand Master did not return for some time as he engaged several chameleon droids in combat. Padmé worried for his safety and decided to go out to look for him with the help of C-3PO and R2-D2. They encountered the chameleon droids along the way, however, a short while after the scuffle, Yoda reappeared with Luminara and Barriss.

Yoda reported that the caves had been destroyed and wondered how the Separatists learned of its location. R2 was able to plug into one of the droid's memory banks and display a hologram that revealed Count Dooku. Dooku had planned for the temple of Ilum to be destroyed, and so sent these droids to undertake the mission.
