Mine- layer Brummer in Norway

Aft of the Brummer mine- layer

During the German invasion of Norway ( Operation Weser Exercise ) in World War II, the ship, together with the minesweeper Rauma , sank the German minesweeper R 17 in Horten am Oslofjord in the early morning of April 9, 1940 , but then fell the following day during the surrender of Hoarding in German hands. Two days later it was taken over into the Navy under the name Albatros , but then renamed Brummer on May 16, 1940 , in honor of the artillery training ship Brummer, which sank on April 9, 1940 .

The ship was now equipped with four 12.7 cm guns, two 3.7 cm guns and four 2 cm anti-aircraft guns, from the summer of 1943 with three 10.5 cm anti-aircraft guns, two 3.7 -cm-Flak and ten 2-cm-Flak. It was initially used to lay mine barriers off the Belgian and Dutch coasts, and from 1941 in the Baltic Sea.

Together with the former maritime port ships Roland and Cobra on 7./8. The offensive mine barrier "SW 1", which was laid in the southwestern North Sea on August 31, 1940 was the undoing of the British 20th (mine-laying) destroyer flotilla on August 31, when the Express , Esk and Ivanhoe ran into mines in the previously undetected barrier. The Esk sank immediately, the Ivanhoe was badly damaged and sunk by its own fuse as not towable, and the Express lost its forecastle, but could be towed in and was out of action for over twelve months.

During the entire war it also took over escort duties again and again. From 1942 to 1944 it was in service in the North Sea and off Norway. In 1944 it returned to mine-laying operations in the Baltic Sea, where it was used in the spring of 1945 to evacuate German refugees from the eastern provinces ( Hannibal Company ).

The End

During an air raid on Kiel on April 3, 1945, the Brummer , lying in the construction port of Deutsche Werke , was badly damaged. The wreck was scrapped after the war between 1945 and 1948.
