During the Jedi Civil War, Admiral Hetton's flotilla was called up to front-line service, having become one of the few mobile reserve units left in the wake of the disaster at Foerost. Deployed to the Mid Rim after shipping out from Coruscant with the 3rd Marine Battalion onboard, Hetton hoped to harass the flanks of the Sith Empire's line of advance. The battalion's commander, Captain Laera Reyolé, however, had come up with an ambitious plan that aimed to seize the initiative once more. After the successful Iridonia-Lannik Campaign, Hetton continued to hold the line for the Republic throughout the war.
