Reiher was built in 1909 as Yard Number 531 by Bremer Vulkan, Bremen for Argo Line, Bremen. Her port of registry was Bremen and the Code Letters QJSC were allocated. In 1923, Argo Line merged with the Roland Line to form Dampfschifffahrtsgesellschaft Argo mbH. In December 1924, her captain was fined £10 with 10gns costs at the Thames Police Court, London for an offence under the Merchant Shipping Act 1906, having had an excessive deck cargo of mahogany logs which were improperly stored. Around 1925/26, Dampfschifffahrtsgesellschaft Argo mbH was absorbed by Norddeutscher Lloyd. Reiher was transferred to Argo Reederei AG in 1933. On 14 April 1928, Soviet gold valued at  £1,043,000 was transferred from the Norddeutscher Lloyd ocean liner  to Reiher at a position  off Falmouth, Cornwall, United Kingdom. The transfer was to prevent the gold being seized by the French when Dresden docked at Cherbourg, Manche. Reiher sailed to Bremerhaven with the gold, arriving the next day. In 1934, her Code Letters were changed to DOAU. She was transferred to Argo Reederei Richard Adler in 1937 and was renamed Flamingo in 1938. On 1 November 1940, Flamingo was requisitioned by the Kriegsmarine for use as a vorpostenboot, serving with 1 Vorpostenbootflottille as V 109 Flamingo. On 26 June 1940, she was transferred to 3 Sperrbrecherflottille serving as Sperrbrecher 39, and from 1941 as Sperrbrecher 139. On 17 February 1945, she struck a mine off Lindesnes, Norway. She sank the next day  south west of the Lindesnes Lighthouse (. References
