When compared to the large U.S. fleet boats used in the Pacific in WWII, the Royal Navy’s 49 U-class submarines were downright tiny. At just 700-tons submerged and 191-feet oal, these boats were originally designed as coastal training subs. However, with the Italians and Germans giving the UK a run for their money in the Med, the Brits started churning these craft out in numbers.
Armed with a half dozen 21-inch tubes, they could carry 8 warshot torpedoes and a 3-inch pop gun on deck. They gave a good account of themselves, sinking a large number of Axis transports and freighters carrying much-needed supplies to Rommel and his Italian compatriots in North Africa– although they suffered severe losses of their own, with 19 U-class sisters going down during the war.
This brings us to HMS Urge. Commissioned 12 December 1940 at Vickers, she lasted 17 action-packed months during which she managed to torpedo the Italian battleship Vittorio Veneto, damaging her in the First Battle of Sirte. She had better luck on 1 April, 1942 when she torpedoed and sank the 6844-ton Italian Giussano-class light cruiser Giovanni delle Bande Nere.

The Regia Marina’s Giovanni delle Bande Nere, some 10-times HMS Urge’s size, was bushwacked by the hearty British submarine with two torpedos and sent to the bottom on April Fools Day, 1942, breaking in half and taking 381 Italian sailors with her.
However, Urge went missing at the end of that month and was never heard from again.
— That is until 76-year old Belgian diver Jean-Pierre Misson, poking around off Tobruk, Libya, came across something very submarine-like. It now appears that Italian dive bombers reaped retribution for their lost cruiser.
