After the Bismarck had sunk HMS Hood on 24th May 1941 there remained the threat of the Tirpitz. Realising that Saint Nazire could be a haven for the Tirpitz; a bold plan was made to destroy the port facilities. On 26th March 1942, a force consisting of HMS Campbeltown and a flotilla of small launches many carrying commandos, set sail from Falmouth to St. Nazaire. The destroyer carried three tons of explosives and aimed to ram the caisson of the Dock; the explosives timed to detonate some hours later. The commandos would storm ashore and disable many of the port facilities. The Campbeltown was successful and exploded putting the main dock out of action for the remainder of the war. The success of the Raid was a huge boost to morale at home when most of the news was bad. Of the 625 personnel involved 169 were lost, mainly in the burning waters of the estuary, 101 of them having no known grave. Over 200 were made prisoners of war but 239 were able to return to England. Among the 140 decorations awarded were five Victoria Crosses. Living close to Saint Nazaire Matt has conducted extensive research into the Raid and is frequently adding snippets of new and wider information. He is a member of the Guild of Battlefield Guides. Every year he organises a charity walk in memory of the sacrifice to raise awareness and funds for a variety of charities. His talk follows the planning and the Raid in details and discusses some recent new information and finds.
