The Royal Navy planned to build midget submarines capable of planting a nuclear weapon inside Russian harbours, documents newly released at the Public record Office have revealed. Designs were drawn up for the so-called X-craft, which was a development on similar devices that had been used in the 1939-1945 War on missions, including the crippling of the German battleship, Tirpitz.
In exile, the Polish Navy operated not only their own ships, but also Royal Navy warships, including a cruiser, destroyers, submarines and motor torpedo boats which fought alongside the Allies in the Battle of the Atlantic, the Arctic Convoys, and at the Normandy landings.
This detailed account not only describes the Polish Navy's contribution to the Allied war effort but also the episode of the Polish destroyer Piorun which took on the Bismarck in a lone gun duel leading to the sinking of the great German battleship.
