Arthur Chin, flying a Gladiator fighter, escorted three SB-2 bombers (flown by Soviet volunteer crews) in a mission against Japanese positions near Kunlun Pass near Nanning, Guangxi Province, China.
He shot down a Japanese A5M fighter which was attacking Lieutenant Chen Yexin's I-15bis fighter, but he was in turn hit by another A5M fighter.
He successfully bailed out of his burning fighter, but not before he suffered serious burns to his face.
