[17] It proved difficult to accurately estimate the size and composition of the Japanese defenses, as attempts to infiltrate reconnaissance parties in the area failed. This resulted in considerable fatigue for the air crews. Earlier, during the Leyte campaign, important documents and diaries were captured by CIC detachments indicating the collaboration of a prominent police officer. Exact tracings and translations were supplied to XXIV Corps prior to attack on these positions. 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. 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.

This diary along with other documents relating to atrocities was used in the trials of Japanese war criminals. [58], Japanese casualties amounted to 3,300 killed and 600 wounded in combat;[59] a further 1,146 were killed or died in the area up to 27 September 1944. [7] The attack was designated Operation Reckless in recognition of the risks involved in carrying it out. Furthermore, the Milne Bay affair demonstrated once again that an amphibious assault without air protection, and with an assault force inferior to that of the defenders, could not succeed. The Kokoda Trail [was] suitable for splay-toed Papuan aborigines but a torture to modern soldiers carrying heavy equipment", Samuel Eliot Morison, Breaking the Bismarcks Barrier, p. 34, Buna was easily taken as the Allies had no military presence there (MacArthur wisely chose not to attempt an occupation by paratroopers since any such force would have been easily wiped out by the Japanese). Rabaul became the forward base for the Japanese campaigns in mainland New Guinea, including the pivotal Kokoda Track campaign of July 1942 - January 1943, and the Battle of Buna-Gona. [citation needed], Three factors conspired to create disaster for the Japanese. Gen. Robert L. Eichelberger, previously commander of the U.S. Adachi's decision may have been motivated by a belief that Hansa Bay would be the target of the next Allied amphibious landing and that he could reinforce Hollandia at a later date. He was succeeded in September 1942, by Capt. [56] Historian Edward J. Drea attributed the success of the operation largely to MacArthur's bold decision to exploit intelligence gained through code breaking, and judged it was "MacArthur's finest hour in World War II and ULTRA's single greatest contribution to the general's Pacific strategy". The majority of the Allied force was provided by the United States, with the bulk of two United States Army infantry divisions being committed on the ground.

Japanese plans to occupy Port Moresby were negated by losses during the Battle of the Coral Sea and Battle of Milne Bay. [36] The air and naval attacks succeeded in isolating the remaining Japanese forces in New Guinea. [34][35] During the same period, American air and naval forces sank many of the Japanese ships which were attempting to transport reinforcements to the Hollandia and Wewak areas; these attacks were guided by intelligence gained from breaking the Japanese codes. ATIS received and translated in April 1944 the diary of prisoner of war Hiroshi Horikoshi, a civilian employee (interpreter) with the Japanese 14th Army, who was captured at the same time. 117, Infringement of the Laws of War and Ethics by the Japanese Medical Corps, contains information on violations of the Geneva Convention on the rules of warfare and points out how, time and again, medical personnel put to death their own patients.

The Japanese invasion of the Dutch East Indies began on 10 January 1942, and the Imperial Japanese Army overran the entire colony in less than three months.

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. 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. RAAF radar could not provide sufficient warning of Japanese attacks, so reliance was placed on coastwatchers and spotters in the hills until an American radar unit arrived in September with better equipment. To help ensure soldiers turned in any souvenirs of intelligence interest, the CIC established a souvenir grab bag. This contained items of no intelligence value, such as Japanese postcards, stationery, pictures, and clothing, and any soldier who handed over a souvenir needed for intelligence analysis was allowed to take an item from the grab bag in exchange. Over 170 were published, including many extracts from diaries and notebooks. The campaign resulted in a crushing defeat and heavy losses for the Empire of Japan.

[27] As the Japanese ground forces pressed toward Port Moresby, the Allied Air Forces struck supply points along the Kokoda Track. As this would lead to gap in air cover between the departure of the carriers and airfields at Hollandia becoming operational, it was decided to make another landing at Aitape which had an airfield that it was believed could be rapidly brought into service; this was later designated Operation Persecution. [9] Few combat units were stationed at Hollandia in early 1944. Most important of all, the bombers of MacArthur's air forces, under the command of Lieutenant General George C. Kenney, had been modified to enable new offensive tactics. This information resulted in the Americans speeding up their invasion convoy by a day.

Cushing, realizing the possible significance of the documents, notified his superiors who in turn notified the Allied Intelligence Bureau in Brisbane. These provided the first clues to breaking the Japanese Navys operational codes. The story of the capture and return of the Z documents is detailed in Appendix II. This document provided a complete list of approximately 40,000 Japanese Army officers together with their assignments. Copies of the documents were made in Brisbane and the original documents were returned to the aircraft crash site by another submarine. This contest produced a number of valuable documents and propaganda leaflets.

[16] Only about 500 of the 11,000 personnel were ground combat troops, being drawn from several antiaircraft batteries. It is important to note that all ATIS units maintained close relations with the CIC units and Australian Army Field Security Service, since these units were largely responsible for the collection and dispatch of captured documents in forward areas to the language personnel stationed with tactical units.
