SM U-56

For other ships of the same name, see German submarine U-56.

SM U-56 was one of the 329 submarines serving in the Imperial German Navy in World War I. U-56 was engaged in the naval warfare and took part in the First Battle of the Atlantic.

On November 2, 1916, U-56 was attacked by gunfire from the Russian destroyer Grozovoi off Khorne Island, Norway (near Vardö). U-56 was survived this attack. U-56 put the crew of the Norwegian merchant ship Ivanhoe ashore at 07:45 on November 3 at Lodsvik. The Norwegian sailors were abroad during the action the previous day and their description matches the Russian account.[1]
