Even though the war had started one month earlier it took until October 1, 1939 before Germany lost it's first warship. The old minesweeper M-85, which had been built in 1918 was sunk by a mine laid by the Polish submarine Zbik in Danzig Bay. Ironically Zbik was already out of the war, she was interned in Sweden on Sept. 25, 1939 following her only mission in the Second World War, that mission was to lay mines in the Gulf of Gdansk. Twenty-four of the crew of M-85 went down with the ship.
