The identity of this later victory, achieved on 23 September 1940, is believed by one source to be the future German ace Hans-Joachim Marseille. Flying Bf 109 E-7, "Werknummer" (W.Nr) 5094, Marseille was pursued to the Cap Gris Nez area near Calais, France, and forced to take to his parachute. He was later rescued by a Heinkel He 59 float plane. Tuck was credited with the destruction of W.Nr. 5094, whose pilot, Marseille, was the only recorded German airmen rescued in the location on that date. Tuck's official claim was for a Bf 109 destroyed off Griz Nez at 09:45—the only pilot to submit a claim in that location. Another states that Pilot Officer George Bennions from No. 41 Squadron RAF dispatched Marseille. This same source credits Tuck with a victory over "Oberleutnant" Walter Radlick of III. "Gruppe" of "Jagdgeschwader" 53.
