Beau served as a pilot operating an X-wing fighter for the Rebel Alliance throughout the duration of the Galactic Civil War. They were known by the designation Red Ten.
Following minor wounds sustained in a conflict to seize new experimental TIE fighter prototypes, Beau was assigned to the Mon Calamari Star Cruiser named Liberty in the year 3 ABY. While recovering in the medical bay, Ace Azzameen gifted them Veromulan candies. After healing, they resumed active duty against the Galactic Empire. One year later, Beau fought in the Battle of Endor where they perished in combat with opposing fighters.
