was converted to a minelayer in September 1914. It operated only in the Baltic Sea, where it was used for several mine laying operations during the war. Taken over by Britain in 1919, it was bought back only one year later and uses as a Seebäderschiff again.
From September 1939 on, it was used as target ship for the submarine school in the Baltic Sea. On 07.08.1944 it was sunk after a torpedo hit fired by a German U-Boat.
