I recently read an article about that very event and don't remember it being the last dogfight.
But I do remember that the US crew landed and captured the 2-man German crew, as one tried to run away. The other one couldn't since he was shot in the foot, and the US flier who shot him dressed the wound.
Quite unusual all the way around.
This article was in the August 2008 edition of Flight Journal, which is a fine magazine. The article is rather accurate since it is mostly interviews with the two GIs. It happened on April 11, 1945 and they wounded one of the Germans and put a hole in the fuel tank, forcing the Storch to land. No mention of it being the "last dogfight" but it was close to the end of the Euro-fighting.
For gun content in this thread, 1911 were used to bring down the aircraft and an M1 Carbine was used to capture the German fliers.
One line read; "I flew with my knees as I put a fresh magazine into the .45."
Sounds like the old cavalry days, holding the reins in your teeth while you reload.
