Ebook: 7th U-Boat Flotilla: Doenitz's Atlantic Wolves

The 7th U-Boat Flotilla - 'Wegener' - was formed in Kiel in June 1938 with six boats, only one of which survived operationally to the end of the war. Early war action from Kiel changed completely after the fall of France when the flotilla moved to St Nazaire, where it would remain until the Allied advances led its remaining boats to move to Norway.

Some 114 boats saw service with the flotilla and most of them served in the North Atlantic where their operations almost brought Britain to its knees. The story of the flotilla starts with the story of the convoy predators; through the grim realities of the convoy system whose escorts benefited from Ultra decrypting of the Kriegsmarine's codes; the massacre of the U-boats attempting to halt the invasion of Europe; to the final coda as 14 boats escaped from St. Nazaire to Norway.
