The engagement known as the Ambush at Vale took place in the year 13 BBY. At Vale, Rebel forces launched a surprise attack against the squadron led by Imperial Ace Shea Hublin. Hublin's squadron was a component of Grand Moff Tarkin's fleet operating within Oversector Outer. During the conflict, Hublin suffered severe injuries, resulting in the loss of his leg and half of his right arm. Subsequently, he was reassigned to a command role aboard the Star Destroyer Kabalian Cross.
