On the night of the 28th July 1944 Lancaster III PB172 took off from RAF Grimsby along with 16 other Lancasters from 100 Sqn to bomb targets at Stuttgart, Germany. It was reported by returning crews that there was fighter activity over the target, but none reported any attacks. German documents record that the aircraft crashed on the 29th July 1944 at about 01:55 hrs near to Durmersheim and Oberweier, some 70 km west of Stuttgart. It was likely that the aircraft was hit by flak and disintegrated in mid-air. The aircraft wreckage fell to the ground within a radius of at least 8 km. Parts of the aircraft were found at the last inhabited house in Oberweier in the direction of Winkel, which is about 1½ km to the SSE.

RAF Grimsby - The existing airfield on this site was taken under Air Ministry control in July 1939 and then by the Royal Air Force (RAF) in May 1940. The airfield officially opened, after it was upgraded, during November 1941 and was initially used as a satellite airfield to nearby RAF Binbrook. Although the airfield was officially designated as RAF Grimsby it was known as RAF Waltham by both the local residents and service personnel on the base. This misnomer caused some confusion as there was an active airfield at RAF White Waltham near Maidenhead in Berkshire.

(1) Flt Sgt. Macdonald was the first to bail out of the aircraft and had no knowledge of the fate of the remainder of the crew. The circumstances leading to his capture have not been established but he was eventually incarcerated at Stalag Luft 7 located in Bankau, Silesia, Germany (now Bąków, Opole Voivodeship, Poland). It was opened on 6th June 1944, and by July held 230 RAF aircrew prisoners. They were joined by members of the Glider Pilot Regiment captured at the Battle of Arnhem in September 1944. By the 1st January 1945, the camp held 1,578 British, American, Russian, Polish and Canadian personnel.

On the 19th January 1945, 1,500 prisoners were marched out of camp in the bitter cold. On the 21st January they crossed the river Oder and reached Goldberg on the 5th February where they were loaded onto a train. On the 8th February they reached Stalag 3A which was located about 32 miles south of Berlin near Luckenwalde. The camp already held 20,000 prisoners, consisting mainly of personnel from Britain, Canada, the US and Russia. The camp was liberated by elements of the Russian Army on the 22nd April 1945.

(2) The fate of Flt Sgt. Martens was unknown until a Canadian Military Court was convened at Aurich in Germany between the 15th and 25th March 1946.

A Canadian forces investigation team was made aware of the murder of an Allied airman which lead the team to discover the remains of an airman in the Oberweier cemetery. The remains were disinterred, and an autopsy carried out on the 30th July 1945. The results positively established that the remains were those of Flt Sgt. Martens and that he had suffered a fatal gunshot wound to the head.

The court charged two German nationals of committing a war crime in that they at the village of Oberweier, Kreis (District) Rastatt, Germany, on or about the 20th July 1944, in violation of the laws and usages of war, were concerned in the killing of Conrad William Martens, a member of the Royal Canadian Air Force, a PoW.

Those charged were Wilhelm Jung who was the former Burgomeister (Mayor) of Oberweier and also the Ortsgruppenleiter (Local group leader of the Nazi party), and Johann Georg Schumacher, who was a former Wehrmacht Gefreiter (equates to senior private) and a member of Landesschützen Batallion No. 404 (local defence forces) based at Rastatt. He was detailed to guard a group of French PoWs who worked on the local farms. He was also a Landwachtmann (Auxiliary policeman).

The court heard that Flt Sgt. Martens had successfully bailed out of the aircraft and landed close to Oberweier, which is to the south of Rastatt. He was captured by a Landwachtmann, named Johann Reiter, who handed him over to a Reinhard Strohm who was the local leader of the Landwacht (Auxiliary police). Shortly later a Landwachtmann, named Peter Scherer, appeared on the scene and Strohm handed over the custody of the airman to him. Scherer was to take the airman to the Rathaus (Town hall) and hand him over to Jung. Strohm then returned to the crash site to guard the wreckage until he was relieved by Wehrmacht personnel. En route to the Rathaus Scherer and Flt Sgt. Martens were joined by August Mack.

Testimonies from several witnesses describe differing versions of what transpired after the group arrived at the Rathaus. However, what is certain is that Flt Sgt. Martens was held in a cell and Jung was informed of the presence of the captured airman. Jung then telephoned the Kreisleiter (County leader, Nazi party) of Rastatt, a man named Heinrich Dieffenbacher, for instructions. It was reported that the Kreisleiter made it clear to Jung that the airman was to be shot. Schumacher suggested that the airman should be held overnight and then delivered to Rastatt the following morning. Jung however ordered Schumacher to shoot Flt Sgt. Martens although Schumacher was reluctant to carry out the order without the presence of someone else. An Oscar Anselm was ordered to accompany Schumacher.

Anselm and Schumacher marched Flt Sgt. Martens on the road from Oberweier to Muggensturm. En route Schumacher shot the airman once in the back and a second time in the head. Schumacher reported the shooting to his Company Commander who made a few notes after which Schumacher returned to his duties.

The airman was left at the side of the road until later that morning when Jung ordered that the body be brought back to Oberweier and buried in the local cemetery A witness placed the location of the shooting at about 150 metres from a crucifix which is standing outside of the village of Oberweier.

A local expert, Helmut Böttcher, who was a teacher and also a former Ortsvorsteher (village representative or spokesperson) believed, of the several crucifixes in the village area the only one that fitted the description of the witness was located on the spot where, on the road leaving Oberweier for Muggensturm, a small road called "Hintere Dollert" joins the "Karlsruher Straße" (This is also very close to the village border between Oberweier and Muggensturm). The crime scene would then have been a further 100 to 150 metres (110 to 165 yards) from this spot which would have been in Muggensturm territory.

In their testimonies to the court Schumacher admitted to the shooting, but Jung denied ordering Schumacher to shoot Flt Sgt. Martens. The court found both men guilty of the charge and sentenced them both to death. The sentences were carried out by firing squad on the morning of the 15th April 1946.

Anecdotal information received indicates that proceedings were started against Kreisleiter Heinrich Dieffenbacher by the Baden-Baden prosecutor in connection with Martens' death. However, it appears that Dieffenbacher was dead or declared dead in 1971, so the proceedings were halted.

Oscar Anselm could not be found and therefore any testimony by him could not be tested before the court.
