Bill Cousins continued at full-back and Jock Woods came in for injured Jack Wallis as the club made only its second visit to nearby Stamford Bridge, to take on Dulwich Hamlet in the final of the London Charity Cup held over from the previous season.

Wimbledon played some exhilarating attacking football in the first half, with Harry Stannard pulling the strings. His passing to the wings and their prompt return towards goal caused much harassment in the Hamlet defence and only keeper Freeman kept them in the game after two early goals put the Dons in command. The first came in the fifth minute, Stannard taking the ball down on the left and finding Vic Bird, he found Jim Smith and from his centre Freddie Gauntlett drove the ball into the net. The second was from a cross by Woods that Bull beat Freeman to and headed home. Jim Haydock had to run out and kick clear from Green and, just before the break, Dulwich forced two corners that resulted in a keen tussle in the goal area.

Wimbledon continued to set the pace in the early part of the second half and Freeman fell on a shot from Stannard. Bull, following up, toppled over the keeper and into the net, but Freeman kept grasp of the ball and managed to clear. Hamlet got themselves back into the game, chiefly through the persistence of Connett. Haydock was forced into two saves but was unable to prevent Dulwich setting up an exciting last twenty minutes when Connett started a move that Gray finished with a splendid goal. Ken Lister, Cousins and Haydock were outstanding in preventing any further Hamlet success and, towards the end, the halves regained their mastery over the forwards and the Dons held firm to win one of the oldest trophies in amateur football for only the second time, the first being the 1935/36 final victory over Kingstonian. Hamlet were appearing in their fifteenth final, having won the trophy outright seven times and shared it on three other occasions.
