Fortress of Axion
the Army of the Republic tried to secure this location during the Clone Wars, shortly after the Battle of Muunilinst, but the forces trying to reach the Fortress were decimated by the armies of the Confederacy of Independent Systems which surrounded it. All but Commander Brolis were shot and killed, and Brolis was left to call for reinforcements while holed up inside. The only being sent to extract him was Jedi Master Yoda, who defeated a particularly cunning Hailfire Droid in order to protect their escape.
