Italy Called It 'Obsolete' — Then This Greek Submarine Terrorized Their Navy for 5 Years

November 1940. The Italian Navy owns the Mediterranean. 6 battleships. 19 cruisers. 59 destroyers. Over 115 submarines. Greece has 14aging submarines that Italian naval intelligence doesn't even bother tracking. When Italy invades, everyone expects the Greek fleet to disappear within weeks. But one Greek submarine refuses to accept these rules. Papanikolis is 13 years old. Built in 1927. Slow. Loud. Obsolete by every technical measure. Italian admirals laugh at the idea of Greek resistance at sea. Then Commander Miltiades Iatridis does something no submarine captain is supposed to do: he hunts in the hunter's waters. For five years, Papanikolis turns the central Mediterranean into a hunting ground. Eleven ships sunk. Forty thousand tons of enemy shipping sent to the bottom. Zero crew casualties. And one Italian Navy forced to completely revise its operational doctrine. This is the true story of the Greek submarine that should not have survived, should not have succeeded, and should not have terrified one of the world's most powerful navies. But it did all three. 🎯 If you want more forgotten stories from World War II, subscribe and hit the bell.
