The remains of F/Sgt Gallipeau RCAF, were washed ashore at Varberg on the Swedish west coast and buried in Varberg.
(Well, actually the body of Gallipeau was found by Birger Karlsson, the skipper of a Swedish trawler, see Hallands Nyheter 28 FEB + 03 MAR 1945.) 
The remaining 10 crew members are commemorated on the Runnymede Memorial.

* Liberator XB-P of the same squadron reported a loud explosion at 0304 hours, which may have been KG964 blowing up.
The crew of XB-P also reported the presence of a so-called 'Sperr Brecher' (a ship equipped with anti-aircraft guns and other artillery) in the area,
and reported light flak passing over their aircraft. This may have been what caused the the loss of KG964 (AIR27/1389)
