Generis was home to the Outer Rim Communications Center, of distinct strategic importance. As such, Thrawn himself planned the assault and sent a force composed of his new clone forces. The combination of superior forces and planning ensured victory for the Imperials, over the New Republic forces which included an elite Republic squadron commanded by Pash Cracken. The Imperials won the Communications Center largely intact, as well as gaining control of most of the sector fleet supply depots.
In their retreat, the Republic forces were able to sneak out Travia Chan and her command staff, and deny the Imperials any working ships, but nevertheless suffered an important defeat.
