The Lance, a Nebulon-B2 frigate of the Alliance to Restore the Republic, was slated to initiate an assault alongside the Lion and the Ornik against the Imperial-class Star Destroyer known as the Conqueror. These frigates were supported by fighter squadrons consisting of T-65 X-wing starfighters, RZ-1 A-wing interceptors, B-wing starfighters, and BTL Y-wing starfighters provided additional support.
Given that the Conqueror is present and ultimately destroyed in a separate engagement, the player's choice to destroy it here cannot be considered canon.
