japanese invasion of dutch new guinea

[1][2], Hollandia was situated on the east side of a headland separating Humboldt Bay to the east and Tanahmerah Bay, 25 miles (40km) to the west. Red 1 was found to be better, allowing LVTs and LCMs to come ashore with their infantry charges, but the approaches had to be cleared by engineers to allow the passage of the larger LCMs and even after this had been completed. The plan called for the establishment of a two-battalion front, with troops landed in seven waves at two beaches: Red 1 around the Depapre Inlet and Red 2 on the eastern side of the bay. This procedure called for all documents to be briefly examined, and those of operational value segregated from those having probable or general value and those having no apparent military value, and provisions were made for the translation on a priority bases of those sections of documents containing information of operational value. Joseph J. Rochefort (of the Battle of Midway code-breaking fame). First, they had woefully underestimated the strength of the Allied air forces. The ATIS Information Section supplied information derived from interrogations; translations; and, situation reports, intelligence summaries, maps, photos, and other outside publications. All of these factors had to be taken into account in determining the lines of advance in 1944. The Z Plan [issued as Admiral Kogas Combined Fleet Secret Operations Order No. The Japanese had already captured Rabaul, the capital of the Australian-controlled territory of New Guinea, on 23 January 1942, and early in February Australian and Dutch forces surrendered the island of Ambon in the Netherlands East Indies (modern Indonesia). West Papua is the western half of the island of New Guinea, formerly known as Dutch New Guinea. The sinking of over 25,000 tones of Japanese ships earned the unit the nickname . In New Guinea, U.S. and Australian infantry were moving along the northern coast, pushing the Japanese before them. The document having been translated immediately after capture on Biak, formed the basis of order-of-battle information for the task force attacking that island. One company landed on White 2 and secured Cape Tjeweri, after which a group of 18 LVTs crossed the sandspit to land two more companies near Pim inside Jautefa Bay. After July 1944, however, documents, including published translations, were prepared under the imprint of CINCPAC-CINCPOA, and the title JICPOA was used only for administrative purposes. Air and naval support consisted largely of U.S. assets, although Australia also provided air support during preliminary operations and a naval bombardment force. There was also a small airstrip.To the west, the Cyclops Mountains rise to over 7000 feet (2100 m). [9], The Japanese 8th Area Army (equivalent to an Anglo-American army), under General Hitoshi Imamura at Rabaul, was responsible for both the New Guinea and Solomon Islands campaigns. [34], Wau is a village in the interior of the Papuan peninsula, approximately 50 kilometres (30mi) southwest of Salamaua. At the Kempei Tai (Japanese Military Police) headquarters they found numerous lists of names and evidence of collaboration and disloyalty to the Philippines and the United States. Hollandia was a port on the north coast of New Guinea, part of the Dutch East Indies, and was the only anchorage between Wewak to the east, and Geelvink Bay to the west. [61] U.S. forces undertook mopping up operations in the area until 6 June. [1] All of the various organizations widely disseminated the information contained in the captured records. Engineers operating amphtracks pushed forward from Jautefa Bay to the lake to carry the infantry around the Japanese positions at the lake, completing their flanking maneuver on 25 April. The Aussies were fighting mad, for they had found some of their captured fellows tied to trees and bayoneted to death, surmounted by the placard, 'It took them a long time to die'. The campaign resulted in a crushing defeat and heavy losses for the Empire of Japan. [39] This operation had no effect on the Japanese, as the air units were being held in reserve for a planned major attack on American naval forces in the Central Pacific. [7], MacArthur met with the commander of the Pacific Fleet, Admiral Chester W. Nimitz, at Brisbane between 25 and 27 March to discuss the role of the Navy in the operation. Documents were first captured from a Japanese plane downed in the Pearl Harbor attack. The Allies proceeded to turn the island into an air base. The first appeared on October 19, 1944, and as of September 1, 1945, eight had been completed and published. [14] MacArthur would have liked to deny this area to the Japanese, but he had neither sufficient air nor naval forces to undertake a counterlanding. It made the term amphibious a household word throughout the English-speaking world. At the same time, two sketches were captured at Tacloban, Leyte, which showed the disposition of the Japanese 16th Division. Task Force 74, under British Rear Admiral Victor Crutchley, consisted of the cruisers HMAS Australia and Shropshire plus several destroyers, while Task Force 75 was made up of three U.S. cruisers, Phoenix, Nashville and Boise under Rear Admiral Russell Berkey. It was captured and was found to be carrying a Japanese message. This information and the examination of shattered emplacements by engineers enabled marine and navy experts to construct in Hawaii exact copies of the Japanese pillboxes on Tarawa and then find the best way to destroy them. According to Morison, "the Japanese retreat down the Kokoda Trail had turned into a rout. [23] The Australian and American anti-aircraft gunners of the Composite Anti-Aircraft Defences played a crucial part. Pre-War New Guinea The Japanese Invasion The Turning Point The Long Allied Advance 1943 1944 The New Guinea campaign (January 1942-September 1945) was one of the longest campaigns of the Second World War. A Japanese carrier pigeon landed on a US transport on the way to Kwajalen Atoll in the Marianas. The work contains a complete study on the collection, translation, and processing of captured documents. Adachi ignored this order, and instead decided to concentrate his troops at Hansa Bay and Wewak. The campaign was long and arduous, but by the end of 1944 the Japanese threat was contained in New Guinea. In mid-July 1944, near Moemi, soldiers recovered three cases of buried records, including seven important documents that a Japanese deserter had led them to. The brief spurt of books in 1943 and 1944, when Japanese were able to visit the occupied Dutch East Indies, dealt mainly with Dutch New Guinea, and then only in a very rudimentary way. In the final days of March, the Fast Carrier Force (Task Force 58) attacked Japanese airbases on Palau and islands in the Carolines. [9] The documents were quickly brought back to Hawaii. Free shipping for many products! When Japanese Americans on the West Coast were moved into internment camps in the late spring of 1942, the school moved to temporary quarters at Camp Savage, Minnesota. 10, Restoration of Captured Documents (June 28, 1945). To alleviate this difficulty, in July 1944, an officer was assigned for duty with ATIS for the purpose of organizing a sub-section to clean and restore documents making them more readily legible. [17], After this failure, the Japanese decided on a longer term, two-pronged assault for their next attempt on Port Moresby. This attack, which was designated Operation Cockpit, aimed to prevent the Japanese from transferring air units stationed near Singapore to New Guinea. A complete list of the names of all officers and noncommissioned officers of the Japanese 222nd Infantry Regiment was captured on May 28, 1944. SEATIC and SINTIC operating in Southeast Asia and China received and translated relatively large quantities of captured documents during the war. ", Samuel Eliot Morison, Breaking the Bismarcks Barrier, p. 38. The other landing would be made at Humboldt Bay by two RCTs (the 162nd and 186th) of the 41st Division. The timely publication of 18 of these reports afforded a wealth of information preparatory to the invasion. [41] After rehearsals and loading, on 16 to 18 April the amphibious forces sailed from their bases at Finschafen and Goodenough Island; they joined up with other ships carrying troops bound for Aitape from Seeadler Harbour and then rendezvoused with the escort aircraft carriers providing air cover off Manus Island early on 20 April. They were carrying Admiral Mineichi Koga, commander in chief of the Imperial Japanese Navy, and his staff, including Vice Admiral Shegeru Fukudome, who was carrying the Z plan documents and the associated cipher system. [43][44] Meanwhile, carrier-borne aircraft attacked targets around Wakde, Sarmi and Hollandia from 21 April, destroying at least 33 Japanese planes in the air and more on the ground. [2] SEATIC was part of the South East Asia Command, established at New Delhi, India in November 1943 and moved to Kandy, Ceylon, on April 15, 1944. Operations focused on attacking positions and seaborne traffic around Timor, Ambon, and the Kai and Aroe Islands. Two months after JICPOA was formed US forces invaded the Gilbert Islands. The operation consisted of two landings, one at Tanahmerah Bay and the other at Humboldt Bay, near Hollandia. The landing was supported by carrier-based aircraft of the U.S. 5th Fleet, which had also struck Japanese air installations at Wakde and Sarmi to the northwest. Two major moves were planned for the end of June: Eventually, the Joint Chiefs of Staff realized that a landing and siege of "Fortress Rabaul" would be far too costly, and that the Allies' ultimate strategic purposes could be achieved by simply neutralizing and bypassing it. On September 6, 1943, ICPOA was designated a joint Army-Navy-Marine organization by a CINCPAC directive and was given the name Joint Intelligence Center, Pacific Ocean Areas (JICPOA). They were numerical inventories under 17 principal categories of documents considered to be of probable or general value. These were supported by a force of eight escort carriers of the 5th Fleet. During the early days of the war the Japanese forces were advancing. Instances were noted of officers completely out of their depth, of men eating meals when they should have been on the firing line, even of cowardice. The Z Plan would fall into the hands of the Allies and be translated by ATIS during the early summer of 1944 and immediately be returned to the Japanese. The headland was formed by the Cyclops Mountains, a mountain ridge rising steeply to 7,000 feet (2,100m) and was backed by Lake Sentani, extending 15 miles (24km) east to west. The landings took place at dawn on 22 April after a supporting naval bombardment at each site. Through this, a complete picture of the organization, strength and disposition of this force was gleaned. The Admiralty Islands having been seized a month ahead of schedule, MacArthur accelerated his advance. Excerpts from the citation indicate that he, with great risk to his life made reconnaissance in a number of caves which had been occupied by Japanese, approaching dangerously close to enemy fire and recovered more than 11 cases of enemy documents vitally needed for the successful conclusion of the operation.. In addition, their bomb bays were filled with 500-pound bombs to be used in the newly devised practice of skip bombing. US troops and vehicles along the invasion beach at Korako. In response, on 8 March General Douglas MacArthur sought approval from the Joint Chiefs of Staff to bring forward the previously planned landings at Hollandia to 15 April. The Allied Air Forces acted promptly on this information and sank both Japanese submarines and supply barges. Found on the vessel were Japanese documents, including field orders and prisoner interrogation reports that indicated the Japanese knew when and where the American operation was to take place. [10] After the chief of staff of the Second Area Army travelled to Wewak to deliver Adachi orders in person, he directed that the 66th Infantry Regiment begin moving from Wewak to Hollandia on 18 April; it was expected that this unit would arrive there in mid-June. Land-based aircraft of the Allied air forces softened up the Hollandia area, destroying more than 300 enemy aircraft during the weeks preceding the attack. [20], Since Port Moresby was the only port supporting operations in Papua, its defence was critical to the campaign. During mid-May American forces intercepted a Japanese landing craft near Arare that carried material for reinforcing the Japanese-held islands offshore of New Guinea that were to be attacked as part of the Wakde-Sarmi Bay Operation. U.S. Army Air Forces, Pacific Ocean Area (except the B-29s) were placed under Lieut. In July and August 1945 CIC agents gathered more documents at Kweilin in southern China on the Gui River. For this, he ordered the air arm of Vice Admiral Jisaburo Ozawa's Third Fleet carriers to reinforce the Eleventh Air Fleet at Rabaul. [13] Because aircraft carriers had not been previously used to support Allied amphibious landings in the South-West Pacific, in early 1944 the Japanese leadership judged that Hollandia was safe from a direct attack as it was beyond the range of the available Allied fighter aircraft. Pre-landing reconnaissance efforts were hampered by the destruction of the Australian scouting party that was landed in the area by submarine in late March, and the reality of the terrain was only discovered through aerial intelligence that arrived too late. First, with completion of the reduction of Rabaul, the South Pacific Area was closed as an active theatre, and Halsey left to take command of the U.S. 3rd Fleet. By the end of the war, ATIS had processed over 350,000 documents (or 1,680 cubic feet of records).[17]. Consequently, Japanese efforts to develop the area were delayed throughout 1943 and 1944. In the spring of 1944, ATIS received a document which, after being translated, proved to be of exceptional value and probably considerably shortened the war. In December 1943, an operational order indicating the times and dates at which Japanese submarine were scheduled to appear in designated spots in the Arawe area, New Britain, was translated by ATIS and immediately forwarded to Naval Intelligence where prompt action was taken. By 22 August, about 8,500 Australians and 1,300 Americans were on site. Translation of the official record by the Japanese Demobilization Bureaux detailing the Imperial Japanese Army and Navy's participation in the Southwest Pacific area of the, This page was last edited on 29 January 2023, at 09:02. They were special works, compiled for general reference purposes. JICPOA personnel also served, beginning in January 1945, at the Advance Intelligence Center (AIC), established at the CINCPAC Advance Headquarters at Guam. . Opposing these forces were the Australian 2/5th, 2/6th and 2/7th Battalions along with Lieutenant Colonel Norman Fleay's Kanga Force. The Allied reduction of Rabaul was only made possible by relentless air strikes that took place day after day, but Yamamoto thought the damage inflicted by a few attacks of large formations would derail Allied plans long enough for Japan to prepare a defense in depth. (1944), https://en.wikipedia.org/w/index.php?title=New_Guinea_campaign&oldid=1136220909, 44,000 on Bougainville (politically a part of New Guinea), 30,500 on New Britain, New Ireland, and the Admiralty Islands. Over 170 were published, including many extracts from diaries and notebooks. Interrogation of a prisoner confirmed the fact that supplies were being unloaded at Lae from enemy submarines. After the occupation of Hollandia and Aitape the Allies were in a strong position, but they did not stop there. Current Translation No. [27], The ground forces would be supported by two naval bombardment forces. "[43], Marshal Admiral Isoroku Yamamoto promised the emperor that he would pay back the Allies for the disaster at the Bismarck Sea with a series of massive air strikes. Forward positions would first be established at Milne Bay, located in the forked eastern end of the Papuan peninsula, and at Buna, a village on the northeast coast of Papua about halfway between Huon Gulf and Milne Bay. [12] General Headquarters South West Pacific Area Operational Instruction No.7 of 25 May 1942, issued by Commander-Allied-Forces, General Douglas MacArthur, placed all Australian and US Army, Air Force and Navy Forces in the Port Moresby Area under the control of New Guinea Force. In January 1943 the Allied and the Japanese forces facing each other on New Guinea were like two battered heavyweights. This information was given to the 163rd Infantry Regiment of the 41st Infantry Division who used it in subsequent offensive operations. To demonstrate the seriousness of the effort to the Supreme War Council, multiple shifts of high-ranking personnel were also effected: Both Yamamoto and Ozawa moved their headquarters to Rabaul; and Eighth Fleet commander Vice Admiral Gunichi Mikawa as well as General Imamura's chief of staff were sent to Tokyo with advice and explanations for the respective General Staffs (Admiral Tomoshige Samejima replaced Mikawa as Eight Fleet commander). Miscellaneous identifications taken from documents captured in early November in the Pinamopoan Area, Leyte, gave the first indication of the Japanese 1st Divisions presence in this area. The attack failed, and the Japanese were driven back toward Wewak. hbspt.enqueueForm({ Base ATIS received a document in March 1945 giving a complete record of the Japanese monitoring of Allied radio communications in the Philippine Islands during the period from October 1942 to December 1943. This discovery resulted in a hurried revision of the assault plans regarding these islands. During the initial phase in early 1942, the Empire of Japan invaded the Australian-administered Mandated Territory of New Guinea (23 January) and the Australian Territory of Papua (21 July) and overran western New Guinea (beginning 29/30 March), which was a part of the Netherlands East Indies. The documents were then sent on to ATIS, SWPA, for final examination. This success was attributable to Milne Bay's Australian and US defenders together with the crews of the (mostly Dutch) merchantmen that had delivered vital supplies and reinforcements to the garrison. More than 6,000 graduates served throughout the Pacific Theater during the war and the subsequent occupation of Japan. [65][18] In mid-July, the Japanese launched their counterattack with around 20,000 troops, resulting in heavy fighting further inland during the Battle of Driniumor River. White 1 would be the main landing, as it provided the only spot where the larger LSTs could land, while White 2 would be secured with smaller LVTs and DUKWs, which would be used to cross the shallow entrance to Jautefa Bay. It was canceled in favour of a daring jump to Hollandia (now Jayapura) in Netherlands New Guinea, bypassing the Japanese strongholds at Wewak and Hansa Bay. The Japanese also seized the key oil production zones of Borneo, Central Java, Malang, Cepu, Sumatra, and Dutch New Guinea of the late Dutch East Indies, defeating the Dutch forces. Today known as Jayapura, in 1941 Hollandia (140.707E 2.543S) was the largest settlement in the Dutch half of New Guinea.It was located on the only really first-class natural harbor on the north coast of Dutch New Guinea, Humboldt Bay, though it had only primitive port facilities. Roscoe H. Hillenkoetter, who later became the director of the Central Intelligence Agency. At the Quebec Conference in August 1943, the leaders of the Allied nations agreed to this change in strategy focusing on neutralizing Rabaul rather than capturing it.[50]. While captured records were quickly evaluated in the field, almost all were eventually sent back to Hawaii, and some of those on to the Washington Document Center in Washington, D.C.[12] Although JICPOA was a major player in the captured documents intelligence business, it was ATIS, however, during the war years that handled the most documents. [8], The Japanese high command intended to hold Hollandia. The plane in which Koga was flying crashed at sea, with no survivors. This bombardment was augmented with air strikes from carrier-borne aircraft, while two destroyer-minesweepers, Long and Hogan, swept the bay ahead of the main landing force. Army units in the South Pacific were transferred to MacArthurs direct control in June, and the U.S. 13th Air Force was moved to the Southwest Pacific Area (SWPA) to form, with the U.S. 5th Air Force, the new Far Eastern Air Force, which was commanded by Gen. George C. Kenney in addition to his position as commander of Allied Air Forces SWPA. Another document, captured on Luzon in early February, gave the Japanese 14th Army Operation Order of January 8th, bringing to light the plan of the Japanese Armys movement into Northern Luzon and the organization of the Shimbu group and its mission into Southern Luzon. Having been organized along lines completely unorthodox, these were invaluable documents to the G-2 Section, especially as this Force was a major enemy unit on the left flank near La Union, Luzon, at that time. [36], The Australians decisively turned back the Japanese assault in the ensuing 2931 January 1943 Battle of Wau. Historians acknowledge that the deciphering of the Z Plan was one of the greatest single intelligence feats of the war in the South West Pacific Area. 7 was cancelled and no record is held that No. Also captured on January 19th was a radio chart that was used by I Corps Signal officers to gain highly satisfactory results in the monitoring of Japanese radio communications. [21][22] Of the total force, 22,500 combat troops were assigned to the landing at Aitape; while the rest (nearly 30,000) were allocated to the Hollandia landings. The report contained 28 pages of translations, each translation accompanied by a photostatic copy of the original document and authenticated under oath by the translation. Allied planners believed that the two beaches were connected by a road, and that another road suitable for vehicle traffic ran inland towards Lake Sentani. ", Samuel Eliot Morison, Breaking the Bismarcks Barrier, p. 120, The first strike, on 7 April, was against Allied shipping in the waters between Guadalcanal and Tulagi. [22] The cost to the Allied fighters was high. region: "", In addition, about 5,400 survivors of the Japanese defeat at Buna-Gona were moved into the Lae-Salamaua area. In early 1943, it became apparent, as the Allies assumed the offensive, that the volume of documents captured would far exceed the capacity of personnel available to translate each and every document in full. The Netherlands, Britain and the United States tried to defend the colony from the Japanese forces as they moved south in late 1941 in search of Dutch oil. I Corps Commanding General was informed in detail of a major enemy operation involving several divisions and embracing the entire Corps front from Rosario to Puncan. [25] But fighters did provide cover for the transports, and for bombers when their targets were within range. Horikoshi, upon arrival at ATIS, at first denied all knowledge of any atrocities but on being confronted with his diary, admitted that such things had occurred. Often, they consisted of combined translations of several documents relating to the same subject, such as (No. The umbrella term for the series of strategic actions taken by the Allies to reduce and capture the vast Japanese naval and air facilities at Rabaul was Operation Cartwheel. MacArthur's plan was bold, as it involved making a large amphibious landing deep behind the front lines in New Guinea. Then began the grueling Kokoda Track campaign, a brutal experience for both the Japanese and Australian troops involved. I and II were published on March 19, 1945 and June 23, 1945, respectively. The Dutch surrendered on 8 March. This bombing operation was also the moment in the New Guinea campaign when Japanese air power no longer threatened the Allies. The battle of Hollandia (22-27 April 1944) was part of Operation Reckless and saw the Americans leapfrog past a series of Japanese bases to capture a key position on the northern coast of New Guinea, catching the Japanese almost entirely by surprise and winning an unexpectedly easy victory.. Base ATIS was closed at Brisbane on June 4, 1945, and established several weeks later in Manila. This airfield was of great value to the Australians during the fighting for northeast Papua. In February 1943, the first contingent of twenty graduates from the Navys Japanese Language School at Boulder, Colorado arrived at ICPOA and began interrogating prisoners of war and translating captured documents. 102103, The Japanese drive to conquer all of New Guinea had been decisively stopped. In late 1943, the Information Section was given the task of writing Briefs consisting of a summary and highlights of Enemy Publications and Current Translations. Advancing on Australia The Japanese effort at the start of World War Two was focused on conquest. The submarine picked up the documents on May 11th and sailed to Darwin. During the second phase, lasting from late 1942 until the Japanese surrender, the Alliesconsisting primarily of Australian forcescleared the Japanese first from Papua, then the Mandate and finally from the Dutch colony. The whole northern coast of the island was now in Allied hands and airfields from which bombers could strike the southern Philippines were soon in operation. Interestingly enough, among these records was a complete listing of the Japanese Imperial Army Ordnance Inventory. Twelve of these were scheduled to be produced, beginning in March 1943.

Tweet. Although the quantity of documents captured in South East Asia and China were not as voluminous as those found elsewhere, nevertheless there were major collections captured. Approval was granted four days later. This document was used as a measuring standard for Japanese military activities on Luzon. In March 1943, a document was captured showing the submarine schedule between Lae, New Guinea, and New Britain. Red 2 beach was found to be highly unsuitable and the promised roads were non-existent. [15] The only Allied response was a bombing raid of Lae and Salamaua by aircraft flying over the Owen Stanley Range from the carriers USSLexington and USSYorktown, leading the Japanese to reinforce these sites. According to Morison, the Japanese "never again risked a transport larger than a small coaster or barge in waters shadowed by American planes. It was occupied by the Japanese during their invasion of the Dutch East Indies in 1942, who planned to use it as a base for their expansion towards the Australian mandated territories of Papua and New Guinea. Urgent information was extracted before rushing the documents on to the Advanced Echelon where they were sorted, stamped, examined, and translated as necessary. They totaled 104 in number. The gunners got a lot of practice; Port Moresby suffered its 78th raid on 17 August 1942.
