German submarine U-35 was a Type VIIA U-boat of Nazi Germany's Kriegsmarine. She was built three years before the start of World War II. The submarine was laid down on 2 March 1936 by Friedrich Krupp Germaniawerft at Kiel, launched on 24 September 1936, and commissioned on 3 November that year under the command of Kapitänleutnant (Kptlt.) Klaus Ewerth. The U-boat was featured on the cover of Life magazine on 16 October 1939, as in the days preceding, it "courteously" rescued all the sailors of a Greek ship that it was about to sink.

U-35 was scuttled just three months into World War II in November 1939. During her service, she conducted two war patrols and sank four vessels for a total loss of 7,850 tons while damaging one vessel of around 6,014 tons.

U-35 was ordered by the Kriegsmarine on 25 March 1935 (technically in violation of the Treaty of Versailles, but consistent with the soon to be signed Anglo-German Naval Agreement). Her keel was laid down on 2 March 1936 by Friedrich Krupp Germaniawerft in Kiel as yard number 558. She was launched on 24 September 1936 and commissioned on 3 November of that year under the command of Kptlt. Klaus Ewerth.

Like all Type VIIA submarines, U-35 displaced 626 tonnes (616 long tons) while surfaced and 745 t (733 long tons) when submerged. She was 64.50 m (211 ft 7 in) in overall length and had a 45.50 m (149 ft 3 in) pressure hull. U-35's propulsion consisted of two MAN 6-cylinder 4-stroke M6V 40/46 diesel engines that totaled 2,100–2,310 PS (1,540–1,700 kW; 2,070–2,280 bhp). Her maximum rpm was between 470 and 485. The submarine was also equipped with two Brown, Boveri & Cie GG UB 720/8 electric motors that totaled 750 PS (550 kW; 740 shp). Their maximum rpm was 322. These power plants gave U-35 a total speed of 17 knots (31 km/h; 20 mph) while surfaced and 8 knots (15 km/h; 9.2 mph) when submerged. This resulted in a range of 6,200 nmi (11,500 km; 7,100 mi) while traveling at 10 knots (19 km/h; 12 mph) on the surface and 73–94 nmi (135–174 km; 84–108 mi) at 4 knots (7.4 km/h; 4.6 mph) when submerged. The U-boat's test depth was 220 m (720 ft) but she could go as deep as 230–250 m (750–820 ft) without having her hull crushed. U-35's armament consisted of five 53.3 cm (21 in) torpedo tubes, (four located in the bow and one in the stern). She could carry up to 11 torpedoes or 22 TMA mines or 33 TMB mines. U-35 was also equipped with a 8.8 cm SK C/35 naval gun and had 220 rounds stowed on board. Her anti-aircraft defenses consisted of one 2 cm (0.79 in) anti-aircraft gun.

Pre-war

U-35 was known as the "bad luck boat" of the 2nd U-Boat Flotilla ("Saltzwedel") due to several accidents. She was rammed by a freighter in 1937, overrun and badly damaged by the pocket battleship Admiral Graf Spee in 1938, and was struck by an aircraft in 1939. She also had some success; U-35 (together with U-28), was the first U-boat to patrol the Atlantic, sailing under the command of Hans-Rudolf Rösing to Ponta Delgada in the Azores. She then undertook several patrols to Spain, Ceuta, Gibraltar and Morocco under the command of Hermann Michahelles and Werner Lott. After the death of Michahelles in a car accident, Otto Kretschmer was briefly given U-35 as his first U-boat command. Before taking over as the temporary skipper, Kretschmer, while serving as the watch officer, was accidentally left on the deck while U-35 dived during maneuvers and nearly drowned. During another peacetime drill in 1938, her sister boat, U-30, was involved in a near-fatal collision with U-35.

Last pre-war patrol

U-35's last pre-war patrol began on 27 August 1939, and took her from Memel (in the Baltic) to Kiel, where she arrived on 1 September, the first day of the invasion of Poland.

First war patrol

The U-boat departed Wilhelmshaven on 9 September 1939. That day, the submarine HMS Ursula fired the first British submarine torpedoes of the war when attacking U-35 about 23 nmi (43 km; 26 mi) north of the Dutch island of Schiermonnikoog. The U-boat escaped without damage and sailed northabout the British Isles to attack shipping.

On 18 September she stopped a group of three fishing trawlers west-north-west of St.Kilda. She sank two with gunfire, the 326-ton Arlita and the 295-ton Lord Minto after confiscating their radios and fishing gear but allowing their crews to evacuate. A third trawler, Nancy Hague, was allowed to proceed after taking on the crews of the other vessels.

After 14:10 on 21 September, U-35 fired three torpedoes at Convoy OA-7 south-west of the Isles of Scilly. She missed a destroyer and a tanker, but damaged the 6,014-ton British tanker Teakwood. The damaged ship was taken to Falmouth in Cornwall, escorted by HMS Ardent. The one sailor killed onboard Teakwood during this attack was the only person to have been killed during World War II in association with U-35.

At 18:45 on 1 October 1939, 42 miles off Ushant, U-35 stopped the unarmed neutral 2,239-ton Belgian merchant ship Suzon, which was carrying 2,400 tons of pit props from Bordeaux to Cardiff. After the crew abandoned ship after an inspection, she was torpedoed and sunk.

Diamantis

About 13:15 on 3 October, 40 miles west of the Scilly Islands, U-35 stopped the 4,990-ton Greek freighter Diamantis, which was taking 7,700 tons of manganese ore from Pepel, Sierra Leone, to Barrow-in-Furness. Like Suzon, she was a neutral, but carrying a strategic cargo to Britain and therefore a "legitimate target". The crew, misunderstanding the U-boat's instructions, abandoned ship prematurely. After two G7a torpedoes exploded prematurely, the ship was sunk by a G7e torpedo. Because the ship's lifeboats were not suited for use in bad weather, Lott decided to take all crew members aboard.

U-35's commander Werner Lott later commented:

In the rough weather I would not have been able to examine the ship's papers, so I gave a signal to follow me. I wanted to go to the Irish coast where I knew there would not be such rough weather. They did not follow me so I fired a shot from my gun at the bow of the boat. This had the result that the crew panicked and jumped into the small boats. One could foresee that with the rough seas that they would overturn.

The next day, 4 October, U-35 was seen by people in Ventry and Ballymore, Co. Kerry easing into the bay. The U-boat launched a dinghy and brought ashore the 28 Greek sailors from Diamantis.

The U-boat returned to Wilhelmshaven on 12 October after 34 days at sea where Lott was reprimanded for his actions, which were regarded as having endangered his crew.

Commemoration

On Saturday, 17 October 2009, more than 200 people attended various celebratory events in Ventry to mark the rescue and landing of the Greek seamen. The occasion was organised by the newly formed Ventry Historical Society.

The main ceremony was held on the green in front of Quinn's Pub, where an inscribed commemorative stone was erected. Guests included the German Ambassador Dr. Busso von Alvensleben and the Mayor of the Oinousses Islands in the Aegean, Evangelos Elias Angelakos, who unveiled the memorial stone. Other guests included descendants of Panagos Pateras, the captain and owner of the ill-fated Diamantis, officers of Southern Command, members of the Irish Coast Guard, the crew of the Valentia lifeboat, and a troop of Sea Scouts from Tralee.

The secretary of the historical society, Dr. Breandán Ó Ciobháin, delivered a welcoming address in Irish, English, Greek, and German, and invited the German ambassador to address the gathering:

I'm deeply moved about this generous gesture of erecting this memorial. In that terrible war, which we all remember very well, it was indeed an exceptional action that we are going to honour today. I'm more than happy that nowadays our three countries are united in the European Union and that we can be sure that anything like that will never occur again. The only thing that should survive is the sense of magnanimity and of courage that will serve as an example for all of us.

Mayor Angelakos said it was a great honor to attend the Ventry ceremony 70 years after the incident: "I would like to remind you of the magnanimous stance of Werner Lott, the commander of the U-35." The occurrence is one of only two such instances in World War II, where a German submarine crew risked its own safety to protect the crew of a vessel they torpedoed and sank.

Second war patrol

U-35 sailed from Wilhelmshaven on her second and final war patrol on 18 November 1939. On 29 November 1939 U-35 was scuttled by its crew in the North Sea, in position 60°53′N 02°47′ECoordinates: 60°53′N 02°47′E, after a depth charge attack from the British destroyers Kingston, Icarus, and Kashmir. Lord Louis Mountbatten, commanding the British squadron, took the extraordinary step of stopping his ships for an extended period of time and sending out boats to rescue the crew of the German submarine adrift in water. Consequently, unusual among U-boats lost during the war, all 43 hands on board survived and were taken prisoner. Indeed, every member of the U-35 crew during its short World War 2 service survived the war.

Submarine S-181 U-31

 Scale 1:350 Brand Hobbyboss (Kit Score 9/10)

U-31 (S181) is a Type 212A submarine of the German Navy, and the lead ship of her class.

U-31 was built by TKMS, with construction taking place at the shipyards of Thyssen Nordseewerke of Emden and Howaldtswerke at Kiel. Launched on 20 March 2002, U-31 was commissioned alongside her sister ship U-32 by German Minister of Defence Peter Struck in Eckernförde on 19 October 2005. U-31 is propelled by one diesel engine and an electric motor driven by nine fuel cells, making the submarine virtually undetectable.

Korvettenkapitän Bert Petzold is the submarine's commanding officer.

History

U-31 was built in two sections, the stern and propulsion by Nordseewerke, Emden and the bow at Howaldtswerke-Deutsche Werft, Kiel. The boats of the Type 212A class cost around 500 million euros to build. Equipped with fuel cell technology and stealth skin, they are almost undetectable, and are able to remain submerged for up to three weeks . The fuel cells are virtually emission free, with the exception of distilled water, resulting in less noise, heat and exhaust fumes.

U-31 and U-32 were commissioned in a joint ceremony at Eckernförde on 19 October 2005 by Defence Minister Peter Struck, in the presence of the Inspector of the Navy Vice- Admiral Wolfgang E. Nolting. They and their sister ships are stationed in Eckernförde and form part of the 1st Ubootgeschwader (1st Submarine Squadron) in Einsatzflottille 1.
