In the year 3 ABY, as part of a carefully planned final push to divert the Galactic Empire's forces, the Rebel Alliance's Twenty-First embarked on a mission to the planet Bestine IV, enabling the Alliance Fleet to successfully withdraw from the Mid Rim. Word regarding the Twenty-First's actions ultimately made its way to the Alliance's 61st Mobile Infantry. Maximian Ajax, a sergeant in one of the company's units, relayed the information to First Sergeant Hazram Namir while they discussed the diversionary operation.
Alexander Freed's 2015 novel, Battlefront: Twilight Company, included a reference to the Bestine IV mission.
