In April 1951 the disappearance of HM submarine Affray knocked news of the Korean War & Festival of Britain from the front pages of national newspapers. Affray had put to sea on a routine peacetime simulated war patrol in the English Channel. She radioed her last position at 21.15hrs on 16 April 30 miles south of the Isle of Wight
- & preparing to dive. This was the last signal ever received from the submarine. When divers eventually discovered Affray they found her resting upright on the sea bottom with no obvious signs of damage to her hull. Hatches were closed tight & emergency buoys were still in their casings. It was obvious that whatever had caused Affray to sink & end the lives of all on board had occurred quickly. Fifty-six years later in this compelling maritime investigation Alan Gallop uses previously top secret documents interviews with experts & contemporary news sources to explore how & why Affray became the last British submarine lost at sea
- & possibly the greatest maritime mystery since the Marie Celeste.
