The Sqn was detailed to provide 16 aircraft for a mission to attack the communications centre of Pforzheim near Stuttgart.

The aircraft took off from RAF Hemswell commencing 15:22 hrs on the afternoon of the 23rd February 1945. The weather was cloudy on take off but cleared shortly after reaching the French coast. The markers were clearly seen and well placed and bombing under the Master Bomber’s instructions at 7,000 ft was well concentrated and appeared very successful.

Enemy opposition experienced by the Sqn though slight was accurate, and light flak appeared effective. Fighter opposition was met and Fg Off. Ythier, on his 16th operation, failed to return. All remaining aircraft landed safely at base.

PB780 was attacked by a Ju88 night-fighter within minutes of leaving the target area. The port wing caught fire and the order to abandon the aircraft was issued.

There were 11 Lancasters claimed by 4 Luftwaffe night-fighter pilots in and around Pforzheim. Currently it has not been possible to attribute the loss of PB780 to a particular night-fighter.

The aircraft crashed at Neuhausen in southern Germany which is some 12½ km SE of Pforzheim.

The bodies of Fg Off. Ythier, Flt Sgt. Lewis and Sgt. Conning were recovered from the wreckage of the aircraft.

(1) In a brief by the legal staff of the War Crimes Group (NW) Flt Sgt. Clark, who witnessed the events leading to what he believed to be the murder of Fg Off. Albert William Delieu, provided the following statement:

"On 23rd February, 1945, we were briefed to bomb Pforzheim, and after we had dropped our bombs at approximately 20:05 hrs, we were attacked by a German night fighter from underneath our port wing. The effect of this attack set both port engines on fire and also Nos. 1 and 2 port fuel tanks.

The order to bale out was given by Fg Off. Ythier at approximately 20:10 hrs, and the bomb aimer (Fg Off. Delieu) and I left the aircraft almost simultaneously. Owing to a faulty parachute I alighted on the ground badly injured and observed Fg Off. Deliue alight some 50-100 yds away. (As far as I can remember the name of the village was Neuhausen, and we alighted roughly 500 yds. from the nearest houses). Fg Off. Delieuimmediately stood up and snapped off his harness. He then started to run to the nearest hedge when a crowd of people appeared and intercepted him.

The last I saw was he appeared to be fighting with them, and my attention was then diverted by the approach of two soldiers who searched me and carried me off to prison.

Next day I was taken out and put in an ox cart and Fg Off. Delieu's uniform dumped on top. During the drive to Pforzheim I inspected the uniform, and found it to be covered with blood and the uniform itself had large cuts in various places. I attempted to question my guards but owing to the difficulty of language I could elicit no information. They merely pointed out vaguely where the members of the crew were buried."

The War Crimes Group North West Europe (NWE) requested a preliminary investigation be conducted and an interim report sent their office. They appreciated that the evidence was vague and the case may be dropped unless definite information could be obtained as to the identity of the persons committing the crime.

Fg Off. Delieu’s death was investigated but on the 18th February 1948 the War Crimes Group (NWE) decided to close the file.
