History
The 30th Flotilla was founded in October 1941 under the command of Kptlt. Helmut Rosenbaum. The boats reached Constanza after a transport over land and canals. The operational area was limited to the Black Sea. Its history ended in September 1944, when the three last Flotillas boats U-19, U-20 and U-23 were scuttled on 10 and 11 September, 1944 near the Turkish coast.
