“Hiroshi Ōshima”的意思、由来-开放百科全书

Baron {{Nihongo|Hiroshi Ōshima|大島浩| Ōshima Hiroshi|extra= April 19, 1886 – June 6, 1975}} was a general in the Imperial Japanese Army, Japanese ambassador to Germany before and during World War II — and unwittingly a major source of communications intelligence for the Allies. His role was perhaps best summed up by General George C. Marshall, who identified Ōshima as "our main basis of information regarding Hitler's intentions in Europe". After World War II, he was convicted{{citation needed|date=September 2018}} of war crimes and sentenced to life imprisonment.

Biography

Early life

Ōshima was the son of a prominent Japanese samurai family from Gifu Prefecture, his father {{Nihongo|Oshima Ken'ichi|大島健一 |Ōshima Ken'ichi}} having served as Minister of War from 1916 to 1918. Ōshima graduated from the 18th class of the Imperial Japanese Army Academy in June 1905 and was promoted to second lieutenant in June 1906 and to lieutenant in June 1908. He graduated from the 27th class of the Army War College in May 1915, and was promoted to captain the following year. From 1918 to 1919, he served in Siberia with the expeditionary forces, and was appointed assistant military attaché in the Japanese embassy to the Weimar Republic. Promoted to major in January 1922, he served as a military attaché to Budapest and Vienna from 1923 to 1924. After his return to Japan, he was promoted to lieutenant colonel in August 1926; following a promotion to colonel in August 1930, he served as commander of the 10th Field Artillery Regiment from 1930 to 1931.^[1]

Military and diplomatic career

In 1934, Colonel Ōshima became Japanese military attaché in Berlin. He spoke almost perfect German, and was soon befriended by Joachim von Ribbentrop, who was Adolf Hitler's favorite foreign policy advisor at that time. Although Hitler ostensibly used the Foreign Ministry (Auswärtiges Amt) for his foreign relations, he was in fact more dependent on the Dienststelle Ribbentrop, a competing foreign office operated by the ex-champagne salesman. Ōshima's importance for Hitler during that period can be seen in the fact that following the conclusion of the Anti-Comintern Pact, the US Ambassador in Japan, Joseph Grew estimated that the agreement was mainly the result of Ōshima's work, without the participation of the Japanese Ministry of Foreign Affairs.^[2]

Ōshima was promoted to major general in March 1935. Under Ribbentrop's guidance, Ōshima met privately with Hitler that fall. With the support of the Nazi leadership and the Imperial Japanese Army General Staff, Ōshima progressed rapidly while in Berlin. He attained the rank of lieutenant general and was appointed ambassador to Germany in October 1938; he then transferred to the army reserve. During his early months as ambassador, according to evidence presented later at the Nürnberg Trial of Major War Criminals, he plotted the assassination of Joseph Stalin through Russian agents who were sympathetic to his cause.^[3] In a conversation Ōshima had with Heinrich Himmler on 31 January 1939, he expressed the hope that German-Japanese cooperation in the field of intelligence would lead eventually to the disintegration of the Soviet Union.^[4] Ōshima was instrumental in the forging and signing of the Anti-Comintern Pact on 25 November 1936 and the Tripartite Pact on 27 September 1940.

Relations between Germany and Japan became strained after the Molotov–Ribbentrop Pact in August 1939. In September 1939, Ōshima was recalled to Japan (with Saburō Kurusu succeeding him); he returned via the United States. At the insistence of the Nazi government, he returned to Berlin as ambassador in February 1941, and remained in that position until the German surrender in May 1945. He dedicated his efforts to closer relations between the two countries. This including military cooperation in the Indian Ocean area (in the form of anti-merchant submarine warfare. Such was his fanatical belief in Nazi ideology that American journalist William L. Shirer, in The Rise and Fall of the Third Reich, wrote that Ōshima "is more Nazi than the Nazis."

Ōshima's close relationship with Hitler and Ribbentrop gave him unparalleled access for a foreigner to German war plans and national policy, comparable to that of Winston Churchill with the American war leadership. In turn, Hitler admired the militaristic Japanese and made Ōshima a personal confidante.

Ōshima made visits to the Eastern Front and the Atlantic Wall, and he met periodically with Hitler and other Nazi leaders. Being a meticulous military officer in training, he wrote detailed reports of the information provided to him by the Nazis. These reports were sent by radio to Tokyo in the Purple diplomatic cipher. Unknown to the Japanese, the PURPLE cipher was broken by American codebreakers in 1940. Thus Oshima's reports were read almost simultaneously by his superiors in Japan and by Allied leaders and analysts as "Magic" intelligence. Sometimes the Allies read the reports them before the Japanese did, as transmission problems between Germany and Japan often held up the reports for hours.

Pacific War

Already on 13 February 1941, Ōshima discussed with Ribbentrop the possibility of a joint German-Japanese initiative for war against the British Empire and the United States, and agreeing with him the time was ripe to strike at the British Empire in Asia.^[5] On 23 February 1941, Ribbentrop urged him to press the Japanese government to attack British possessions in East Asia.^[6] On 28 November 1941, in a conversation with Ribbentrop, the German Foreign Minister, he was given an assurance that the Third Reich would join the Japanese government in case of war against the United States.^[7]

Such was Hitler's high esteem that Ōshima was one of only fifteen recipients of the Grand Cross of the Order of the German Eagle in Gold. Hitler awarded the medal following the attack on Pearl Harbor in 1941. The award ceremony was attended by Reich Foreign Minister Ribbentrop and the secret notes of the conference were revealed at the Nuremberg trials in 1945. In addressing Ōshima, Hitler reportedly said:

Germany presses for Japanese attack on Soviets

Despite Ōshima's anti-Soviet positions, the Japanese government in April 1941 concluded a non-aggression pact with Moscow. The German armed forces invaded the Soviet Union in June and the German government was interested in a simultaneous Japanese attack on the USSR. However, prior to the invasion itself, the German government did not update Ōshima about plans of attack. In a conversation held on 17 May 1941, Ernst von Weizsäcker, State Secretary in the German Foreign Office, denied there was any tension with the Soviet government.^[9]

Following the invasion of the USSR on 22 June 1941, pressure was placed on the Japanese government to join the invasion. On 9 July 1942, Ribbentrop tried to convince Ōshima to urge his government to join the attack on the Soviet Union. Ribbentrop's main argument being that "never again would Japan have such an opportunity as existed at present to eliminate once and for all the Russian colossus in eastern Asia".^[10] On 6 March 1943, Ōshima delivered Ribbentrop the following official statement from the Japanese government:

Supporting war crimes

Ōshima's high esteem with Hitler made him privy to some of the planning relating to actions later to be defined war crimes and atrocities. One example was a meeting held between him and Hitler on 3 January 1942, where they both agreed on the action of sinking life-boats working for the rescue of Allied naval personnel fleeing ships sunk in military action. The official text reads:

Ambassador Ōshima heartily agreed with the Führer's comments, and said, "that the Japanese, too, are forced to follow these methods.^[12] }}

At a meeting Ōshima had with Hitler and Ribbentrop on 27 May 1944, Hitler advised that the Japanese government should publicly hang every captured US pilot who was involved in air raids, with the hope this would deter further such attacks.^[13]

Intercepted dispatches

Virtually all of Ōshima's dispatches were intercepted: approximately 75 during the 11 months of 1941, some 100 in 1942, 400 in 1943, 600 in 1944, and about 300 during the just over four months of 1945 when Germany was at war.^[14] For example, in a dispatch decoded on 19 January 1942, Ribbentrop agreed to supply daily intelligence reports to Ōshima, which he could pass on to Tokyo. He warned that "any leakage of these reports due to our fault would be of grave consequence, so all the handling of these reports should be strictly secret". This despite the fact that the Germans often reproached him of the unreliability of the Japanese codes, although Ōshima assured them of its security. This laxity proved to be fatal to Japanese espionage efforts, as even much of the intelligence gathered by the Japanese spy network codenamed TO in Spain (with implicit support given by the Spanish authorities) was channelled through him. This evidence halted the loading of petroleum by the United States onto Spanish tankers in 1944.

While some of his predictions were wrong — Ōshima predicted that Britain would surrender to Germany before the end of 1941 — his reporting of the Nazi leadership's plans and policies and his factual data were invaluable to the Allies. For example, on 6 June 1941, he advised Tokyo that Germany would invade the Soviet Union on 22 June (see Operation Barbarossa).

Another example was in November 1943, when Ōshima was taken on a four-day tour of the Atlantic Wall fortifications on the coast of France. Upon his return to Berlin, he wrote a detailed 20-page report of his visit, giving an account of the location of every German division, as well as its manpower and weaponry. He described tank ditches in detail, armament of turrets located close to the shore, and available mobile forces. This provided valuable intelligence to the planners of the D-Day assault. Connected to this was that the Allies knew that Operation Fortitude was working because just one week before D-Day, Hitler confided to Ōshima that while the Allies might make diversionary feints in Norway, Brittany and Normandy, they will actually open up "an all-out second front in the area of the Straits of Dover". Thus Ōshima dutifully reported that the bulk of German forces would not be waiting in Normandy, but mistakenly, at the Pas-de-Calais area.

His dispatches also proved to be valuable to those who were involved in the bombing campaign in Europe, as Ōshima provided details on the effect of Allied bombing raids on specific German targets, giving valuable and relatively unbiased bomb damage assessments to the Allies.

During and after the war

As the war progressed and Germany began to retreat, Ōshima never wavered in his confidence that Germany would emerge victorious. However, in March 1945 he reported to Tokyo on the "danger of Berlin becoming a battlefield" and revealing a fear "that the abandonment of Berlin may take place another month". On 13 April 1945, he met with Ribbentrop — for the last time, it turned out — and vowed to stand with the leaders of the Third Reich in their hour of crisis. "I do not wish to be treated in the same manner as other diplomats merely by reason of great danger from the ravages of war", he announced. But he was informed that evening by the Foreign Ministry's chief of protocol: all diplomats were to leave Berlin at once by Hitler's direct order. Ōshima had sent his wife to Bad Gastein, a mountain resort in Austria, and the next day left to join her, together with most of the Japanese diplomatic staff.

Less than a month later Germany surrendered and Ōshima and his staff were taken into custody. They were brought to the United States by ship, arriving on 11 July 1945. After interrogation and internment in Bedford Springs Hotel, a resort hotel in the heart of the Allegheny Mountains, Pennsylvania, Ōshima was returned to Japan in November 1945.

Although he enjoyed freedom briefly in his devastated country, he was arrested on 16 December 1945 and charged with war crimes. When brought before the International Military Tribunal for the Far East, he was found guilty of conspiring to wage aggressive war on 12 November 1948 and sentenced to life imprisonment. Ōshima was paroled in late 1955 and granted clemency three years later. Ōshima died in 1975, not knowing that he provided the Allies with invaluable intelligence during the war.
