A highly interesting account of a little-known force


A group of determined human torpedoes, motorboat operators and assault swimmers fought bravely for Italy in the Second World War and inspired fear and respect from the British Navy. The actions of these men severely reduced British naval power in the Mediterranean. Even with small numbers and using relatively limited resources, the commandos were a very effective force in the war against the British. By the end of the war, these men would sink or disable over 73,000 tons of Allied warships and over 128,000 tons of merchant shipping.


The story of the Italian commandos is one of determination and bravery. Their tactics aroused confusion and nervousness with Allied commanders and their crews. Italy’s Decima Flottiglia Mas predates both the US Navy Underwater Demolition Teams that were formed in 1943 and forerunners of the better-known US Navy SEALs and the British Royal Marines Special Boat Service formed as an offshoot of the Special Air Service in 1941. Perhaps the determination and actions of the Decima Flottiglia Mas qualify them as the best commandos of the Second World War.
