On August 29th 1943, the German forces occupying Denmark tried to take control of the Danish armed forces. Both the Army and the Navy were still operating despite the German attack and subsequent occupation of Denmark on April 9th 1940.
In February 1941 the Germans requested that the Danish government surrendered twelve Danish torpedo boats to the German Navy. The Danish government gave in to these demands, but in the end the Germans took only the six fairly new torpedo boats "Dragen, Hvalen, Laxen, Glenten, Høgen and Ørnen", which were handed over - unarmed - to the Germans in April 1941.
As payment for these boats, the Germans agreed to supply
the Royal Dockyard in Copenhagen with materials for the construction
of six new torpedo boats. Some of the promised materials arrived,
but since the Danish Navy suspected that the Germans would
take the new boats when they were completed, the construction
progressed very slowly, and was halted after 29/8 1943.
The officers in the Royal Danish Navy knew that there was a risk that the Germans would try to seize the navy, and had decided that if this happened the Danish vessels should try to break through to neutral Sweden. If this proved impossible the order was to scuttle the ships.
When at 0400 hrs. On the morning of the 29th the Germans attacked the Danish Naval Base at the Royal Dockyard (Holmen) in Copenhagen, it proved impossible for the Danish ships to leave the harbour. German guns placed around the harbour controlled the only way out, and the signal to scuttle the fleet was sent to the fleet. This signal also reached some of the few vessels stationed outside Copenhagen.
Due to luck on the Danish side and bad planning on the German side, the Danes were able to scuttle most of navy, and a few of the ships at sea made it to Sweden. Of the fifty-two vessels in the Danish Navy on the 29th of august, two were at Greenland, thirty-two were scuttled, four reached Sweden and fourteen were taken undamaged by the Germans. The Germans were later able to raise most of the scuttled ships, and fifteen of these were put into some kind of service by the German Navy.
