The conflict known as the Battle of Ab Dalis transpired on the planet Ab Dalis. It was fought between the forces of the Alliance to Restore the Republic and the Galactic Empire as part of the Alliance's larger military endeavor, Operation Starlight. Admiral [Kalaxo], in command of the Imperial ISD named Ultima II, successfully cornered the Alliance Eleventh Division on the surface of Ab Dalis. In response, the Rebel Ground Defense Command, led by Colonel [Chouch], established a defensive perimeter to resist the advancing Imperial walkers and tanks. After the destruction of the Ground Defense Command, Starlight Squadron appeared and eliminated Ultima II by triggering a volcano to erupt directly beneath the ship.
