Polish floating dock captured by German forces at Hela in September 1939

A list dated 17 November 1939 was dealing with ships and floating equipment captured by the Germans in the Polish coastal area. With the German ship breaking company Gemeinschaft Bremerhaven was negotiated about scrapping the ships and equipment not wanted by the military leader of the salvage group. Captured ships not owned by the Polish government were due to the war considered as war prizes and could be used for service. Ships not used for military purposed could be returned for economic reasons to their owners. An item reported 1-5.000 tons floating deck scuttled at Hela [Germans for Hel] next to the Polish mine layer Greif. The heavily damaged dock was to be salvaged before anything could said what to do with it.
