The British submarine, M1 which uniquely carried the firepower of a battleship was discovered 35 miles south-east of Plymouth at a depth of 81 metres by diver and submarine expert, Innes McCartney and boat skipper Grahame Knott.
The hour-by-hour account of the bravery, bungling, helplessness and heroism of men trapped by the sea.
On June 1, 1939, the Submarine Thetis sailed out of Liverpool Bay with 103 men on board for diving trials, but on the very first dive it failed to surface, the escape hatch jammed, and help was too slow in coming.
