Hit by the night fighter pilots Major Wilhelm Herget of the Stab I./NJG 4 (flying a Bf 110 G-4 from Florennes airfield) and Leutnant Wilhelm Henseler of the 4./NJG 1 (flying Bf 110 G-4 G9+CM from St Trond (Sint-Truiden) airfield).
After the war, an investigation officer from the Royal Air Force Missing Research and Enquiry Service (MRES) was tasked with locating the remains of the missing crew member(s).
Original German documents, burial records and eye witness accounts were utilised to establish the location of the crash site, the cause of the loss and the initial fate of the crew; information was recorded in a MRES Investigation Report
As part of the process, any remains that were located were exhumed, identified (wherever possible) and concentrated (reinterred) at one of the Commonwealth War Graves Commission’s (CWGC) Cemeteries in the country that they fell, in accordance with Government policy at the time.
Graves were marked with a simple wooden cross, which was replaced by the familiar CWGC headstone during the 1950’s.
Missing airmen who could not be found, or formally identified, had their names commemorated on the Air Forces Memorial at Runnymede, which was unveiled in 1953.
CWGC records show that DAA Swain’s remains were located at the Henri Chapelle US Cemetery. However, the MRES officer recorded that the remains had initially been buried in the Military Cemetery at Malmedy, before being exhumed and moved by US Army personnel.
