At the beginning of 1942, the Tirpitz, the heaviest battleship ever built by a European navy was on the cusp of breaking out into the north Atlantic. The prospect of a huge German battleship patrolling the Atlantic posed a grave threat to the convoys that served as the lifeline for an embattled Britain. After attempted bombing raids failed, a new and far more daring plan was created; to ram a battleship loaded with explosives into St. Nazaire, the only dry dock capable of supporting this unstoppable juggernaut.

This volume in the Casemate Illustrated series gives a clear overview of the planning and execution of the raid and its aftermath, accompanied by 125 photographs and images, including colour profiles and maps.
