History

[edit]

Bunnemann was built as yard number 108 by Schiffsbau & Maschinenfabrik Hansa, Tönning for the Kaiserliche Marine. She was launched in July 1918 and was commissioned on 6 September 1918. She was allocated to II Geleit-Flotille. On 3 July 1920, she was declared a prize of war and allocated to the French Navy.[1]

In 1921, Bunnemann was sold. She was renamed Kergroise and converted to a fishing trawler. She was owned by the Société des Pêcheries de St. Pierre et Miquelon. The Code Letters OKSX were allocated.[2] In 1931, she was sold to the Compagnie Laurentaise de Chalutage, Lorient, Morbihan, France.[4] The fishing boat registration L 2109 was allocated,[1] In 1934, her Code Letters were changed to FNVH.[5]

On 23 September 1939, Kergroise was requisitioned by the French Navy for use as a minesweeper. The pennant number AD 134 was allocated.[1] She was scuttled at Loirent on 18 June 1940.[6] Kergroise was refloated on 4 April 1941 and subsequently repaired. She was commissioned by the Kriegsmarine on 13 October 1942 as the vorpostenboot V 422 Kergroise. She was bombed and sunk off Lorient by Allied aircraft on 30 June 1944.[1]
