Fleet Group One was the command of Bothan Admiral Traest Kre'fey during the Battle of Coruscant. Its flagship was the Bothan Assault Cruiser Ralroost. Kre'fey's tactics during the battle were rather conservative—thousands of his ships defected to Fleet Group Two, which was under the command of General Garm Bel Iblis. The majority of the surviving ships retreated along with the Ralroost to the New Republic bastion of Kashyyyk, and it conducted a series of raids on Yuuzhan Vong targets throughout the galaxy in the following months. The fleet group was once again led by the Ralroost in the massive ambush at Ebaq 9 in the Deep Core, which saw the New Republic decimate a Vong armada led by Warmaster Tsavong Lah. The fleet group's assets were divided and reassigned when the Republic was reorganized into the Galactic Alliance.
