The most notable aspects of the Hellenic Royal Navy's participation in World War II include the operations of the destroyer which, until sunk in Leros on September 23, 1943, was the most successful Allied destroyer in the Mediterranean Sea; the participation of two destroyers in Operation Overlord; and the story of the destroyer "Adrias", which while operating close to the coast of Kalymnos in October 1943 hit a mine, resulting in the loss of the vessel's prow, while blowing the two-gun forward turret over the bridge. After some minor repairs at Gümüşlük Bay in Turkey "Adrias" managed to return to Alexandria in a 400-mile trip, even though all the forepart of the ship, up to the bridge, was missing. Six Greek warships participated in the Sicilian landings and in the subsequent Italian campaign.
