The Endeavor, a Rebel EF76 Nebulon-B escort frigate, engaged the Imperial frigate Malevolent in a balanced duel.
In Legends continuity, the space battle shown in this mission, along with the ships involved, is considered C-canon. However, the battle's result is not fixed, as it changes depending on the player's choices. Because of this, and without further canonical details, it's best to think of the battle as not having any major consequences, such as the destruction of either vessel.
