Confederate First Fleet
From Wookieepedia, the Star Wars wiki.
The First Fleet was one of the three main fleets of the Confederate Navy during the Clone Wars. For a time, it was based at Yag'Dhul; it later participated in Operation Durge's Lance and the Battle of Duro.
Given its location in the Core, it presumably also participated in the Battle of Coruscant at the end of the war.
