The full story of one of the greatest Allied shipping losses of World War II For the first time, this book describes how U-482 managed to slip undetected into the busy shipping lanes of the North Channel and carry out the last great U-boat patrol of the war. In the autumn of 1944 World War II was coming to an end, and the U-boats in the Atlantic had been beaten back through a massive program of Allied shipbuilding combined with tactical, technological, and intelligence improvements. The threat to Allied shipping had diminished but not disappeared, and a lone U-boat on its first active patrol slipped into the North Channel--in just a few days five ships lay broken on the seabed including the Empire Heritage, one of the largest Allied ships lost in the entire war. Also lost was a rescue ship attacked while trying to rescue survivors from the Empire Heritage; the Jacksonville, an American tanker sailing out of New York; and a RN corvette sent to hunt the U-boat down. This is the story of the attack, the aftermath, and the men involved.
