I hope the local politbureau

won't object to taking up BravoZulus' previous thread. It's just an amazing story imho, so I wanted to share more details of the story, I stole on FB.
Submarine L55 in the dock at the Kronstadt Marine Plant in 1928
HMS L55 was a British L class submarine built by Fairfield Shipbuilding and Engineering Company, Govan, Clyde. She was laid down on 21 September 1917 and was commissioned on 19 December 1918.
In 1919, the L55 operating in the intervention against Soviet Russia and on June 4 was sunk in battle with the destroyers Azard and Gavriil. In 1926, the submarine was discovered, in 1928 it was raised and by 1931 it was repaired and put into operation of the Soviet Navy under the same name (Л-55 in Russian spelling). In 1939 she was transferred to a training submarine. During the war it was used as a charging station for other submarines.
After raised the submarine, the bodies of 38 crew members were discovered, who were sent to England. Prior to this, the British press denied the victims of the sinking of the submarine.
P.S. The rise of the L55 was carried out by the salvage ship Kommuna, operating in the Russian fleet from 1915 to the present.
