• "On 24th May 1943, admiral Donitz ordered his U-boats to withdraw from the north Atlantic. The Royal Navy had won the most important victory in all the centuries of its existence...It was overwhelmingly a British, and specifically a Royal navy, triumph. The war for Europe still had two hard years to run before the final and total victory; but by May 1943 the Navy had already made the most important strategic contribution to the defeat of an expansionist Germany - for the second time in twenty-five years. It was the finest hour of British seapower in a uniquely turbulent century"
