5th U-boat Flotilla

The 5th U-boat Flotilla (German 5. Unterseebootsflottille), also known as Emsmann Flotilla, was a U-boat flotilla of the German Kriegsmarine during World War II.

The flotilla was formed in December 1938 in Kiel under the command of Korvettenkapitän Hans-Rudolf Rösing. It was named in honour of Oberleutnant Hans Joachim Emsmann, a U-boat commander during World War I, who died on 28 October 1918 after his U-boat SMU UB-116 was sunk by a mine. The flotilla was disbanded in January 1940 and the boats were all transferred to 1st Flotilla.

The flotilla was re-formed as "5th U-boat Flotilla" in June 1941 under the command of Kapitänleutnant Karl-Heinz Moehle as a training flotilla with her base in Kiel. In 1946 Moehle was sentenced to five years in prison, after being found guilty of passing the Laconia Order to new U-boat commanders before they went out on patrol. He was released in November 1949.
