The Gunners faced Sheffield United in the final at Wembley, and narrowly won 1-0 thanks to a Ted Drake goal.
They had beaten Bristol Rovers, Liverpool, Newcastle (after a replay), Barnsley and Grimsby Town en route to Wembley.
Early in the season, Arsenal had lost the Charity Shield 1–0 to Sheffield Wednesday, but two months later claimed their biggest win of the season, 7–1 at Aston Villa, with Ted Drake setting the all-time record for the most goals in one English top division match, after scoring all seven goals.
He would finish as the club's top scorer that season with 24 league goals and 3 in the FA Cup.
Arsenal entered the FA Cup in the third round, in which they were drawn to face Bristol Rovers.
