On the night of March 28, 1942, in one of the most audacious raids of World War II, 600 British commandos and seamen set out across the English Channel in a flotilla bound for occupied France. Using a destroyer as a floating bomb, they were to destroy the dry dock used to service Germany's much-feared battleship Tirpitz, while commandos went ashore to blow up other key targets. Success came at a terrible cost, and here Robert Lyman tells the story in gripping detail.
