history
The boat was intended to be used as a commercial submarine as U Oldenburg . Even before the USA, which had been neutral during the First World War , entered the war, it was converted into a U-cruiser from February 15, 1917, following a war order "P".
First in command was Corvette Captain Waldemar Kophamel . Under his command, U 151 sank 12 ships with a tonnage of around 29,000 GRT in the period from July 21 to December 26, 1917.
The U-cruiser started her second mission under Korvettenkapitän Heinrich von Nostitz and Jänckendorff (1881-1953) on April 18, 1918 from Kiel. U 151 was the first German submarine to be used off the North American coast. It arrived off the American coast on May 22nd. It laid sea mines off the Chesapeake and Delaware Bay and then began cruiser warfare in the New York City - Virginia maritime area . It returned to Germany in July. During the 94-day mission, 23 ships were sunk and the submarine cables between New York and Nova Scotia and New York and Colón / Panama were cut.
Due to maintenance work, the U 151 was not operational again until October 1918. It expired again on October 17, but was recalled three days later and was no longer used in the last weeks of the war until the armistice on November 11.
On November 24, 1918, the U 151 was delivered to France as spoils of war and sunk there as a target ship off Cherbourg on June 7, 1921 .
