Four years after destruction of Alderaan, a battle occurred above the planet, when the Galactic Empire attacked a New Republic convoy trying to sneak through the debris field on its way to Project Starhawk's secret base. Titan Squadron were to follow the convoy and allow them to jump to hyperspace to calculate all possible destinations along their trajectory, however the mission was foiled when a local Imperial II-class Star Destroyer, the Tormentor, arrived and attacked the convoy. Titan Squadron were able to gain the sector coordinates, but all New Republic forces as well as the Tormentor were destroyed.
