Battle of Acherin (Clone Wars)

Fearing the Galactic Republic's rule was becoming more and more absolute, the planet Acherin had joined the Separatist cause early on, and the Battle of Acherin would come to last throughout much of the Clone Wars.

Towards the very end of the Wars, the Acherin Separatist commanders began ceasefire-negotiations with the Jedi Commander Garen Muln. Progress was going well, until Supreme Chancellor Palpatine issued Order 66, marking Muln a traitor to the Republic. When the clonetroopers came for him, commanders Raina Quill and Toma helped Garen Muln flee Acherin in secret.

Realizing the threat of the new Galactic Empire, the people of Acherin began a resistance movement, and would fight in yet another battle, that lasted almost a year.
