history
After U 151 and U 156, the U 140 was the third German submarine to be used against North American shipping during the First World War . The commandant was Corvette Captain Waldemar Kophamel . On 6 August 1918, the cruiser destroyed the Diamond Shoal- lightship before Cape Hatteras . On August 10 he narrowly escaped a water bombing of the destroyer USS Stringham . U 140 had tracked the Brazilian steamer Uberaba , which was able to make an emergency call. According to Halpern, it was the only encounter between a destroyer and a submarine in North American waters. Kophamel was forced to stop the operation due to leaking oil. Kophamel had sunk around 30,000 t of ship space during the operation.
On the return journey, the cruiser was contacted by radio telegraph from U 117 , which threatened to run out of fuel. Apparently at the end of September both boats met off the Faroe Islands , where U 140 gave around 25,000 liters of fuel to U 117 , which was then able to return home.
U 140 was delivered to the USA on February 23, 1919 . The boat was sunk on July 22, 1921 by the destroyer USS Dickerson during an exercise off Cape Charles by artillery .
