This Corellian fleet participated in combat as an element of the Galactic Republic's retaliatory maneuvers throughout the Great Sith War circa 3996 BBY. It successfully impeded a combined Krath and Sith incursion targeting the Corellian Run, which had already resulted in the seizure of planets such as Ando, Rodia, and Bothawui. The Corellians achieved a number of significant triumphs at locations including Gyndine, Denon, and Gamorr, thereby assisting in shifting momentum towards the Republic and the Jedi's advantage.
