Lt William H. Allen and 5 Heinkel He 111

[George 118]

Hello,
On September 5, 1944, Lieutenant William H. Allen (343rd Fighter Squadron, 55th Fighter Group) became an Ace in one day when he shot down five Heinkel He 111 as they took off from an airfield north of Göppingen, Germany.
I would like to request information about the Heinkel He 111, including the units they served in and the names of their pilots.
