Battle of Borosk
this was the name given to the defense of the planet Borosk by the Imperial Remnant, against the Yuuzhan Vong forces that decimated the Empire at the Battle of Bastion. Using information and tactics that had been supplied by the Galactic Alliance, Grand Admiral Gilad Pellaeon managed to rally the remaining Imperial fleet to defend Borosk, repelling the advance of B'shith Vorrik's forces and driving them out of Imperial space.
