In March 1942, at perhaps the darkest moment of World War Two for the Allies, Britain launched a nearly suicidal raid on the Nazi-occupied French port of St. Nazaire, which the German Navy was using as a dry dock for ship repairs (the Tirpitz, the sister ship of the Bismarck, was scheduled for repairs there). Destroying it would hinder the U-boat campaign and force German ships to return hundreds of miles to home ports. The plan was for British commandos to attack the port and simultaneously to use an explosives-laden, American-built ship dating from World War One, the Campbelltown, as a gigantic torpedo, launching it into the docks. The first element of Operation Chariot went disastrously. The second proved spectacularly successful. The detonation of the Campbellown put the St. Nazaire dry dock out of commission for the war's duration.

To be published on the 80th anniversary, Giles Whittell's book will offer the definitive account of the raid, which was undertaken by Royal Navy and British commandos, most of whom were killed or captured. The Greatest Raid provides a gripping and authoritative narrative of one of the most daring military operations ever undertaken.
