The official death toll of Exercise Tiger was 749 men, which is more than perished at the hands of the real enemy during the Utah beach landings. It was the worst loss of life since the Japanese attack on Pearl Harbour.
Exercise Tiger is one of Britain’s most harrowing wartime secrets. It involved the slaughter of young American soldiers on the shores of a Devon beach.
At the time the incident was hastily covered up, and the bodies of the GIs who were killed were buried in complete secrecy.
If Allied high command wanted to use Exercise Tiger to give their soldiers a taste of what they would experience during the D-Day landings, they cut far too close to the core. The sea ran red with their blood as corpses bobbed in the surf.
Officially, the deaths were attributed to a surprise attack launched by German E-boats the day after the exercises. The authorities have never acknowledged what happened on Slapton Sands on April 27, 1944, although as time has passed information about the tragedy has become more widespread.
The whole point of the exercise was to make the dress rehearsal as realistic as possible. Dummy enemy positions were built alongside concrete pillboxes. There were 30 men in each assault team armed with flamethrowers, bazookas, machine guns, and mortars.
