- Japanese submarine I-29
"I-29", code-named "Matsu" (松, Japanese for "pine tree"), was a
B1 type submarineof the Imperial Japanese Navyused during World War IIon two secret missions with Germany, during one of which she was sunk.
Type B Submarines
This was the most numerous class of Japanese submarines - almost 20 were built, of which only one ("I-36") survived. These boats were fast, had a long range, and carried a seaplane, launched via a forward catapult.
The keel of "I-52" was laid on
29 September 1940at the Yokosuka Naval Yard, and she was commissioned on 27 February 1942, into the 14th submarine squadron under the command of Lieutenant Commander (later Captain) Izu Juichi (伊豆壽市).
These were missions enabled under the
Axis Powers' Tripartite Pactto provide for an exchange of personnel, strategic materials and manufactured goods between Germany, Italy and Japan. Initially, cargo ships made the exchanges, but when that was no longer possible submarines are used.
Only four other submarines had attempted this trans-continental voyage during World War II: "I-30" (April 1942), "I-8" (June 1943), "I-34" (October 1943) and the German submarine "U-511" (August 1943). Of these, "I-30" was sunk by a mine and "I-34" by the British submarine "Taurus". Later, the famous Japanese submarine "I-52" would also share their fate.
"I-29" participated in missions supporting the attack on
Port Moresbyin New Guinea, and also in the futile search for Task Force 16, that launched the Doolittle Raidon Tokyoin April 1942.
"I-29's" reconnaissance of
Sydney harbouron the 23rd May 1942 resulted in the Japanese midget submarine attack on Sydney Harbour.
In April 1943, "I-29" was tasked with a "Yanagi" mission. She was commanded by Captain Masao Teraoka, submarine flotilla commander — indicating the importance of the trip. She left
Penangwith a cargo that included two tons of gold. She met Fregattenkapitän Werner Musenberg's Type IXD-1 U-boat, "U-180" on 26 April 1943off the coast of Mozambique.
During this meeting that lasted over 12 hours due to bad weather, the two Axis submarines swapped some very interesting passengers. "U-180" transferred Netaji
Subhash Chandra Bose, a leader of the Indian Independence Movementwho was going from Berlinto Tokyo, and his Adjutant, Abid Hasan. "I-29" in turn transferred two Japanese Navy personnel who were to study U-boat building techniques in Germany: Commander (later Rear Admiral, posthumously) Emi Tetsushiro, and Lieutenant Commander (later Captain, posthumously) Tomonaga Hideo (who is later connected with the German submarine, "U-234"). Both submarines returned safely to their bases. "I-29" dropped off her important passenger at Sabang harbour on an isolated We islandlocated to the north of Sumatraon 6 May 1943, instead of Penang, to avoid detection by British spies.
December 17, 1943, "I-29" was dispatched on a second "Yanagi" mission, this time to Lorient, Franceunder star Japanese submarine Commander Takakazu Kinashi. At Singaporeshe was loaded with 80 tons of raw rubber, 80 tons of tungsten, 50 tons of tin, 2 tons of zinc, and 3 tons of quinine, opium and coffee.
In spite of Allied
Ultradecrypts of her mission, "I-29" managed to reach Lorient 11 March 1944. On her way she was refueled twice by German vessels. Also, she had three close brushes with Allied aircraft tracking her signals. Of special note is the interaction with six RAFaircraft including two "Tse-tse" De Havilland Mosquitofighters equipped with 57 mm cannons from the No. 248 RAFSquadron off Cape Penas, Bay of Biscaycoord|43.66|N|5.85|W|, and the protection provided to her during the entry into Lorient by the Luftwaffe's only Long Range Maritime Fighter Unit, "V Gruppe/Kampfgeschwader 40" using Ju-88s.
She left Lorient
16 April 1944for the long voyage home with a cargo of 18 passengers, torpedo boat engines, Enigma coding machines, radar components, a Walter HWK 509A rocket engine, and Messerschmitt Me 163& Messerschmitt Me 262blueprints for the development of the rocket plane Mitsubishi J8M. After an uneventful trip she arrived at Singapore in 14 July 1944, disembarking her passengers, though not the cargo.
On her way back to Kure, Japan, she was attacked at
Balintang Channel, Luzon Straitnear the Philippinesby Commander W. D. Wilkins' "Wildcats" submarine taskforce consisting of "Tilefish", "Rock" and "Sawfish", using Ultrasignal intelligence. During the evening of 26 July 1944, she was spotted by "Sawfish" which fired four torpedoes at her. Three hit the "I-29", which sank immediately at coord|20.10|N|121.55|E|. Only one of her crew survived.
Among the dead was "I-29"
'sCommanding Officer, Commander Takakazu Kinashi, Japan's highest-scoring submarine "ace". Earlier in the war, as skipper of "I-29" 'ssister ship "I-19", Kinashi torpedoed and sank the U.S. aircraft carrier "U.S.S. Wasp" and damaged both the battleship "U.S.S. North Carolina" and the destroyer O'Brien during the same attack. O'Brien later sank as a result of the torpedo damage and North Carolina was under repair at Pearl Harbor until November 16, 1942, a spectacular achievement that is still considered to this day to be the most effective torpedo salvo ever fired in naval history. Kinashi was honored by a rare 2-rank posthumous promotion to Rear Admiral.
