Three of the five crew were killed, two survived to be captured, and taken as PoWs. One was killed in 1944 after escaping from a PoW camp.

Took off from Feltwell, Norfolk, 22:00 on 14 July 1940 with the invasion barges in the dockyards of the German port of Hamburg as the target. Failed to return. Three of the crew of five were killed, two taken as PoW. According to the following extract from the the biography of George Grimson, one of the crew (see link #7 for his full biography):

"George Grimson was the wireless operator aboard a No. 37 Squadron RAF Vickers Wellington (serial number "L7792") squadron codes "LF-L" which was shot down on 15 July 1940 during a raid on barges in the dockyards of the German port of Hamburg by the anti-aircraft defences over Bremen. He was one of only two survivors who baled out before the bomber exploded.

Allocated prisoner of war number 134, George Grimson passed through Luftwaffe interrogation centre Dulag Luft, before being sent to Stalag Luft I at Barth, Stalag VIIIb, Lamsdorf and back to Barth before finally being sent to Stalag Luft III"

A persistent escapee from PoW camps, he was promoted to a Warrant Officer while in captivity, and was constantly hunted by the Gestapo agents of SS-Obersturmbannführer Dr. Günther Venediger, while "on the run"; a price was placed on his head and wanted posters printed. He was last seen on 14 April 1944 in the Danzig area and was probably seized by the Gestapo, disappearing in captivity, probably having been captured and murdered by the SS. Body not found/not recovered, and he is commemorated on the Runnymede Memorial.

All three crew killed on 15 July 1940 were interred at New Aumund Cemetery. After the War they were re-interred at Becklingen War Cemetery, Germany.
