St Nazaire
On 28 March 1942, Sub-Lieutenant Wynn was to play a decisive part in the raid on St. Nazaire, the only port on the Atlantic seaboard in which the newly completed German battleship Tirpitz could be docked. The plan, code-named Operation Chariot, entailed a former US Navy destroyer, HMS Campbeltown, carrying 24 time-fused Amatol explosive charges, ramming the gates of St. Nazaire harbour. The ship was to also carry commandos who were tasked with destroying shore-based installations. The charges in Campbeltown would later explode and hopefully destroy the dock caisson. If this was not successful, MTB 74 commanded by Sub-Lieutenant Micky Wynn, was to be armed with two delayed-action torpedoes to be fired at the dock caisson. Also deployed to the raid were two destroyers, a motor gun boat and 16 motor launches.
The Chariot force sailed from Falmouth with MTB 74 towed by Campbeltown. The MTB was equipped with three Packard engines capable of almost 40 knots (74 km/h) and two Ford V8s which were designed for maneuvering at 6 knots (11 km/h). Too fast with one combination of engines and too slow with the other, the MTB was put onto tow until the convoy reached St. Nazaire. The ships crossed 400 miles (640 km) of open sea and were three miles (5 km) up the Loire estuary before the Germans opened fire. Campbeltown, which was flying the German ensign, immediately replied in German by Morse and Aldis lamp, and the enemy batteries held their fire, allowing Campbeltown to move closer to the docks. At 1.27am and closing on the gate, Campbeltown replaced the German flag and hauled up the British ensign. Under intense fire Campbeltown cut through the torpedo net and rammed the dock gates at 1.34. Wynn, who had been cast off from Campbeltown, was ordered to fire his two torpedoes at his secondary target, the gate at the old entrance. Wynn reported to Commander Ryder and was congratulated on his success with a swift drink from a flask.
Having picked up survivors from Campbeltown and an MTB, Wynn was ordered to return to England. He turned his craft and ran his full speed of 40 knots (74 km/h). Wynn spotted two men on a Carley float directly ahead of him. He had to make a snap decision, either to stop—which could be done quickly—or to drive on, which would have meant that the men would be washed off their float and probably drowned. He later recorded, "it was an awful decision . . . I decided to stop the vessel and we pulled up right alongside them. My crew had got hold of them, but unfortunately at that very moment the German shore batteries found their mark and two shells went straight through us." Wynn was blown from the bridge down to the bilges. He was saved by the chief motor mechanic, Chief Petty Officer Lovegrove, who decided to search that area before jumping overboard. He held the severely injured Wynn and joined other survivors on a Carley float. When the Germans found them 12 hours later only three men were left out of 36.
That morning, whilst the Campbeltown was being inspected by Germans, five tonnes of explosive blew up rendering the dock completely useless until after the war. Two days later Wynn's two torpedoes exploded and destroyed the gates of the old entrance. Wynn, now a Prisoner of War and blinded in one eye, heard the explosion. Five Victoria Crosses were awarded for the raid with Wynn awarded the Distinguished Service Cross.
