World War II was an exciting time for special operations and commandos. The advent of airborne operations gave them a whole new angle of approach, and the sheer scale of the war guaranteed that they'd have plenty of chances to use their skills.
But even accounting for those things, operators on both sides of the war distinguished themselves with daring missions.
Here are eight of the craziest:
1. A costly canoe raid against German ships
The "Cockleshell Heroes" were a group of British Royal Marines assigned the task of launching from a submarine and canoeing miles up the River Gironde to place limpet mines against the hull of German ships. The mission hit problems almost immediately as canoes were lost to tide and river obstacles.
Only two of the original five made it to the Bordeaux-Bassens docks. The four men who crewed the canoes placed mines on a few ships, which damaged some commercial vessels. While the material damage was limited, it boosted British morale and forced the Germans to devote more resources to defense in a way similar to the U.S. Army Air Force's Doolittle Raid.
2. The failed attempt to kill Erwin Rommel
Operation Flipper had the lofty goal of crippling an Italian headquarters and intelligence office as well as killing Field Marshall Erwin Rommel. The mission was beset by bad weather and the assault force that hit the German officer's headquarters was smaller than planned.
Still, the British commandos broke into the headquarters building only to learn that Rommel had been delayed in Rome by his own weather problems. Only two raiders survived, but even Rommel admitted that it was a "brilliant operation." He had the senior officer, British Lt. Col. Geoffrey Keyes, killed and buried with full honors and photos sent to the family.
3. Norwegian resistance destroys Germany's nuclear stockpile, twice
A first attempt on the Norsk Hydro Plant, where radioactive heavy water was processed and stored, failed but the survivors and their reinforcements hit the plant on Feb. 28, 1943, despite suffering from starvation and exhaustion. They were able to blow the storage facilities, setting German nuclear research back by at least months.
Months later, a new stockpile of German heavy water was being transported on a ferry when the Norwegian Resistance attacked once again, sinking the ferry and ending Germany's last best chance at a nuclear reactor or bomb. One man, Knut Haukelid, participated in both raids.
4. German paratroopers take the world's strongest fort
In 1940, the Belgian Fort Eben-Emael was arguably the world's strongest fort. Constructed from 1932-1935, it was heavily armed and guarded by upwards of 800 soldiers. But Germany had to destroy or negate it to get the blitzkrieg into Belgium.
They did it in a single morning with 85 paratroopers. The men landed on the fort in gliders and quickly took hold of large sections of it, destroying or capturing the guns aimed at the countryside. When the rest of the German army arrived, the remaining defenders surrendered.
5. Benito Mussolini is rescued from a mountaintop retreat by German paratroopers
In July 1943, Italian defeats turned the country against Benito Mussolini and he was exiled to a series of locations. A German commander was able to track the dictator to Gran Sasso, a mountaintop ski resort accessible only by cable car or glider. At 6,300 feet, it was too high even for an airborne assault.
German Capt. Otto Skorzeny led the glider assault. The paratroopers brought along an Italian general in the hopes that he would prevent a shootout. It worked. The Italian guards decided not to fight when the gliders crashed into the mountains and the paratroopers stormed out. Skorzeny and Mussolini departed on a small, high-altitude plane.
6. British commandos steal a German radar station
The insane plan for Operation Biting called for five groups of British paras to land in German-occupied France, capture a German radar station, and then make off with key pieces of the technology. The men landed under cover of darkness and quickly captured the building. They even managed to grab two technicians with intimate knowledge of the advanced German radar.
Paratroopers who missed their drop zone arrived late to destroy a German pillbox, a situation that almost ended with the withdrawing commandos being killed. Luckily, the men arrived in time to destroy the pillbox as it swept fire on the other commandos. The British escaped with their prize.
7. The British turn an entire ship into a bomb
Dubbed the "Greatest Raid of Them All," the St. Nazaire Raid targeted the only German-held dry dock for heavy ships on the Atlantic that was accessible without passing German defenses. But the dry dock was heavily armed and far upriver.
The British sent a small flotilla of vessels led by the converted HMS Campbeltown. Sixteen were small motorboats, twelve of which were destroyed without reaching shore. But the Campbeltown managed to ram the gates of the dry dock. The Germans captured 215 of the 600 attackers and killed 169 more, but explosives hidden in the Campbeltown exploded the next morning, crippling the facilities.
