The Eighth Fleet was one of the nine main fleets of the Navy under the Galactic Federation of Free Alliances government during the Second Galactic Civil War in 40 ABY. It had been created after the Alliance victory in the Yuuzhan Vong War in 30 ABY, and perhaps even during the Corellian crisis itself.
During the Second Galactic Civil War, it was one of three fleets assigned to Crix Base in the Coruscant system, along with the Third and Ninth. In this role, the Eighth Fleet apparently served as the main defense of the Galactic capital: the Third Fleet was assigned first to maneuvers in the Outer Rim Territories and then to the blockade of Corellia, while the Ninth was an enigmatic new command.
The Seventh and Eighth Fleets finally defected from the Galactic Alliance when the Hapes Consortium joined the Jedi Coalition. Both fleets then fought at the Second Battle of Roche along with the Alliance-in-exile, the Maw Irregular Fleet and the Confederation fleets while the Hapan Home Fleet remained in the Hapes Cluster.
