By 19 BBY, specifically during the Battle of Anaxes, which occurred in the time of the Clone Wars fought between the Galactic Republic and the Separatist Alliance, the Republic Navy possessed a reserve fleet. During the conflict on Anaxes, Jedi General Mace Windu told Jedi General Anakin Skywalker that he feared the Separatists would soon take the planet, and he thought that this loss would put the entire [reserve fleet](/article/reserve_fleet] at risk.
The animated series Star Wars: The Clone Wars first referenced this reserve fleet, though without explicitly naming it, in "The Bad Batch," which served as the premiere episode for the seventh and final season. While the episode was broadcast on February 21, 2020, an earlier version was initially shown at Celebration Anaheim on April 17, 2015, and subsequently on StarWars.com on April 29, as an unfinished story reel within The Clone Wars Legacy multimedia initiative.
