German submarine U-859

U-859 was built in Bremen during 1942 and 1943, and was heavily adapted following her completion in July 1943, with the addition of a snorkel to enable her to stay underwater for longer during the hazardous passage to Penang in Malaya. Thus she was not ready for war service until the spring of 1944, when following her working up period and modifications she departed Kiel for the East.

German Type IXD2 submarines were considerably larger than the original Type IXs. U-859 had a displacement of {{convert|1610|t|LT}} when at the surface and {{convert|1799|t|LT}} while submerged.{{sfn|Gröner|1991|pp=74–75}} The U-boat had a total length of {{convert|87.58|m|ftin|abbr=on}}, a pressure hull length of {{convert|68.50|m|ftin|abbr=on}}, a beam of {{convert|7.50|m|ftin|abbr=on}}, a height of {{convert|10.20|m|ftin|abbr=on}}, and a draught of {{convert|5.35|m|ftin|abbr=on}}. The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines plus two MWM RS34.5S six-cylinder four-stroke diesel engines for cruising, producing a total of {{convert|9000|PS|kW shp|-1}} for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of {{convert|1000|shp|PS kW|-1}} for use while submerged. She had two shafts and two {{convert|1.85|m|ft|abbr=on|0}} propellers. The boat was capable of operating at depths of up to {{convert|200|m}}.{{sfn|Gröner|1991|pp=74–75}}

The submarine had a maximum surface speed of {{convert|20.8|kn}} and a maximum submerged speed of {{convert|6.9|kn}}.{{sfn|Gröner|1991|pp=74–75}} When submerged, the boat could operate for {{convert|121|nmi}} at {{convert|2|kn}}; when surfaced, she could travel {{convert|12750|nmi}} at {{convert|10|kn}}. U-859 was fitted with six {{convert|53.3|cm|in|0|abbr=on}} torpedo tubes (four fitted at the bow and two at the stern), 24 torpedoes, one 10.5 cm SK C/32 naval gun, 150 rounds, and a 3.7 cm Flak 18/36/37/43 with 2575 rounds as well as two 2 cm FlaK 30 anti-aircraft guns with 8100 rounds. The boat had a complement of fifty-five.{{sfn|Gröner|1991|pp=74–75}}

Although U-859 only had a single war patrol from which she never returned, her six month career was highly eventful and carried her halfway across the world and into an entirely different theatre of conflict.

Commanded by Kapitänleutnant Johann Jebsen, U-859 sailed from Kiel for Penang on 4 April 1944, carrying 31 tons of mercury in metal flasks intended for use by the Japanese munitions industry. She avoided shipping lanes and during her time in the North Atlantic, remained submerged for 23 hours every day, running on her schnorkel. She would surface for just one hour each day at 23:00, later reduced to 15 minutes each day.

Three weeks into the voyage, Colin, a formerly-Italian freighter that had been taken over by American authorities and registered in Panama, was slowly steaming unescorted in the North Atlantic following engine failure. U-859 sank her with three torpedoes before proceeding southwards.{{cite web

The boat's voyage continued smoothly for the next two months, rounding the Cape of Good Hope and entering the Indian Ocean without trouble. On 5 July she was spotted by a Lockheed Ventura aircraft, which swooped down on the boat before being downed by her anti-aircraft guns, leaving no survivors. One rating of U-859 was killed and one officer seriously injured. Some sources say the aircraft was actually a Catalina anti-submarine plane.Stalin's Silver, p. 96.

Her second victim became one of the most famous treasure shipwrecks of the twentieth century. The unescorted Liberty ship {{SS|John Barry||2}} was transporting a cargo of 3 million silver one-riyal coins from Aden to Ras Tanura in the Persian Gulf as part of an American government agreement with the Saudi royal family. The coins had been minted in America for King Abdul Aziz Al-Saud and were stacked in huge boxes in the hold, going down with the ship when she was torpedoed at {{coord|15|10|N|55|18|E|type:landmark_region:ZA|name=John Barry/U-859}}, about {{convert|100|nmi}} south of the entrance to the Arabian Sea. A massive salvage operation in 1994 retrieved many of the lost coins.{{Cite web

On 23 September 1944 U-859 was running on the surface, within {{convert|23|nmi|abbr=on}} of Penang and the end of her voyage, when she was intercepted in the Malacca Straits by the British submarine {{HMS|Trenchant|P331|6}}, which had been forewarned of her arrival date and route by decrypted German signals.{{Cite book | last= Hinsley | first= Francis Harry | author-link= Harry Hinsley |author2=E.

The U-boat sank immediately in {{convert|50|m|abbr=on}} of water with several compartments flooded. 47 men drowned, including her commander.

Twenty of the crew escaped by opening the hatch in the relatively shallow sea, struggling to the calm surface. Eleven survivors were picked up by HMS Trenchant immediately following the sinking, and the remaining nine were picked up by the Japanese after 24 hours adrift. They were then taken ashore to await repatriation.{{cite web | title= Interview with U-859 survivor Arthur Baudzus | publisher= Riverdale Electronic Books | url= http://riverdaleebooks.com/baudzus_interview.html | archive-url= https://web.archive.org/web/20050214013707/http://riverdaleebooks.com/baudzus_interview.html | archive-date= 14 February 2005 }} (via Internet Archive)

In 1972 a total of 12 tons of mercury were recovered from U-859 and brought to Singapore. The West German Embassy claimed ownership of the mercury. The Receiver of Wreck took possession of the mercury, and the High Court of Singapore ruled that "the German state has never ceased to exist despite Germany's unconditional surrender in 1945 and whatever was the property of the German State, unless it was captured and taken away by one of the Allied Powers, still remains the property of the German State..."{{cite book | last= Greenwood | first= C.J. | title= International Law Reports: v.56 | publisher= Cambridge University Press | year= 1980 | pages= 40–47 | isbn= 0-521-46401-3}}
