In 5 ABY, the Imperial Center Defense Fleet was attacked by the combined forces of the Rebel Alliance and the Fist of Justice. However, Imperial strength was greater than anticipated and the FoJ fleet suffered early on in the battle. Fearing that his irreplaceable fleet may be destroyed or rendered ineffective, Lord Nihalis pulled his forces out without informing the rebels and leaving them horribly outnumbered. The Imperial victory that followed was quick and decisive, resulting in the destruction of the Home One and the deaths of rebel leaders Gial Ackbar and Crix Madine. After that, the rebels retreated back to the remains of Alderaan and then to Sullust, but their fleet had suffered a terrible blow, and one that they would take a long time to recover from.
