| This Submarine sailed for a North Sea patrol on 4th July 1940 and was expected to return to base on 14th July 1940. The Submarine is thought to have been sunk with all hands after hitting a mine on 9th July 1940. | |
On the outbreak of war in 1939 Admiral Donitzs U-boat flotillas consisted of some thirty U-boats fully operational, with only six to eight at sea at any one time. Their activities were restricted mainly to the North Sea and British coastal waters.
When France fell in the summer of 1940, the ports in the Bay of Biscay gave direct access to the Atlantic, and the ability to extend their reach even to. The Royal Navy was unable to escort convoys much beyond the Western Approaches. In a short time, the Allies were losing 500,000 tons of shipping a month, every month.
Donitz now looked over the far horizons, Americas Eastern Seaboard, the coasts of Africa, and the Mediterranean, where Allied merchantmen habitually sailed alone and unprotected. There was a rich harvest to be gathered in by the long range U-boats, the silent hunter-killers, mostly operating alone.
This book tells their story.
