I’ve posted about this spot before
In the early hours of the 28th of April 1944 eight Landing Ship Tanks (LST’s), full of American servicemen were in Lyme Bay, off the coast of Devon, England. Their purpose to take part in Exercise Tiger, the realistic rehearsals for the D-Day landings in Normandy. The night turned into tragedy as a group of patrolling German e-boats discovered and attacked them. At the end of Exercise Tiger 946 American serviceman had lost their lives.
