In early 1942, things were finally starting to look up for the Allies in Europe. After the Miracle at Dunkirk, the British managed to regroup and deploy their forces elsewhere. The Blitz was over, and the English home islands were safe from invasion (for the time being). Most importantly, the Americans were in the war on the Allied side. The time was right to hit Nazi Germany where it hurt while making the North Atlantic just a little safer for the Royal Navy to operate.
The British set out to destroy the shipyards at St. Nazaire, France.

The French port as St. Nazaire held one of the largest drydocks in the world. The legendary battleship Bismarck was on its way to St. Nazaire when the Royal Navy caught up to her and sunk her. Few other docks could accommodate ships of that scale. So to avoid unnecessary civilian casualties, the British decided to destroy them with a daring commando raid. There was just one problem, the Special Operations Executive believed the mission would require more explosives than they could reasonably carry into the dock.
And all the Navy ships that could destroy the facility were too heavy to get into the Loire Estuary. So instead of using people or guns to destroy the complex, they decided to essentially make one giant floating bomb.
The British needed to destroy the facility's dock, the water pumping machinery, and any U-boats or other shipping in the area. To get the men and explosives close enough to the facility and have enough to actually do the job, the SOE decided to strip a Royal Navy destroyer, making it light enough to slip into the estuary and up the River Loire. After stripping it for weight, the ship would be packed with explosives. The plan was for the commandos to board smaller ships and disembark. Once in the facility, they would set explosives elsewhere in the complex, then blow them up.
All of them, including the giant ship bomb.
The convoy of two destroyers and 16 smaller craft left England and set sail for France on the afternoon of March 26, 1942. After capturing two French fishing boats, they all arrived off the coast of St. Nazaire around 9 p.m. and made their way into the port under a German naval ensign. That's when the RAF began making a bombing run that was supposed to distract the German defenders, but it only served to make the Germans more suspicious. By the time the flotilla of English ships was coming in range of the target, they were challenged by the German navy.
In an instant, all the defenders' searchlights and guns were pointed at the ships. The Germans began to rake the ship with incessant fire, even after the British surrendered. The German fire only increased, so now the British began to shoot back. The HMS Campbeltown, the ship that was laden with explosives, increased her speed.
At 1:30 a.m. the Campbeltown rammed the gates of the dockyard facility, driving the hull into the gate. The commandos finally disembarked as 5,000 German defenders scrambled to make sense of what was happening. Two assault teams, five demolition teams, and a mortar group all spread out into the complex. They moved quickly to take out the various workings of the drydock and the ships there, and they were largely successful, but the effort was not without casualties. The Germans managed to kill many of the raiders.
By this time, escaping back to the ships was not an option. The commando teams' new orders were to escape back to England however they could and to only surrender if they ran out of ammunition. Most of them did. They attempted to piecemeal an escape to a nearby old town and into the outlying woods. They were quickly surrounded and captured by the Germans. Only five managed to make it back to Spain and thus, England.
The Campbeltown wreck was still in the dry dock months later.
The Campbeltown didn't explode right away. It remained lodged in the drydock gates for more than 24 hours as the Germans tried to make sense of the Allied raid. At noon on March 28, 1942, the charges exploded, completely destroying the drydock, along with two tankers moored there. It killed 360 Germans and knocked the drydock out for the remainder of World War II.
Some 169 British troops died in the effort, along with 215 taken prisoner. The Nazis lost two tugs, two tankers, and the drydock in this daring raid but the more strategic importance of the raid was less than welcome. Hitler began to double his efforts to fortify the Western coast of France. By the time D-Day came around in 1944, the new fortifications would cost the Allies dearly.
