In the Second Battle of Antioch, Aldaris and Artanis led their main strike force in an attack on Scion, a province now occupied by the zerg. While the executor was successful in freeing Scion, Antioch was again being overrun.
The second Battle of Antioch was an absolute slaughter. Fenix and a small detachment was left in the province to safeguard it from further assaults; however, with elements of the Fleet of the Executor caught up in war in the adjacent province of Scion, the Antioch defenders were overrun by a swift strike from the zerg. When Fenix called for help, Aldaris told him to hold out as long as he could and assured him that the gods watch over him.
