The Saint-Nazaire Commando: When Britain Destroyed Hitler's Atlantic Fortress

The greatest raid of the war — and the morning after that sealed its legend

British commandos rammed an explosive-laden destroyer into France's largest dry dock, crippling Hitler's Atlantic naval strategy.

The Loire estuary smelled of oil and burning steel as dawn broke on June 26, 1942. In the German-controlled port of Saint-Nazaire, chaos still reigned from the British commando raid that had struck in the early hours of March 28. But on this June morning, three months later, the Nazi propaganda machine finally admitted what they had tried to conceal: the massive Normandie dry dock — the only Atlantic facility capable of servicing the battleship Tirpitz — was destroyed beyond repair.

The raid itself had been suicide dressed as strategy. HMS Campbeltown, a obsolete American destroyer packed with four tons of delayed-action explosives, had rammed the dock gates at 1:34 AM on March 28.
