Today marks the seventieth anniversary of Exercise Tiger - a military training exercise that went catastrophically wrong on the South Devon coast.
A ceremony will take place today at Slapton Sands. The exercise was supposed to be a trial run for the D Day landings, but more than a thousand Americans were killed after being attacked by German ships
There'll also be a special guest of honour. Edward Sobczyk, who's now in his nineties helped save hundreds of lives during the exercise. He was awarded a medal for his bravery - and then stripped of it because President Eisenhower didn't want people to know about it.
