All Hell Let Loose_ The World at War 1939-1945 - Max Hastings [123]
Japan’s 1941–42 military triumphs caused the Western Allies to over-rate its army, as they might not have done had they known of a significant earlier clash, which it had suited both parties to cloak in secrecy. In the summer of 1939, skirmishes between the Japanese and Russian armies on their common border dividing Manchuria from Mongolia erupted into full-scale war, commonly known as the Nomonhan Incident. Since the beginning of the century, powerful voices in Japan had urged imperialist expansion into Siberia. In the aftermath of the 1917 Bolshevik Revolution, for some time Japanese forces deployed there, hoping to stake claims which could later be formalised. Only the belated decision of the Western Powers to support a stabilised, unified Soviet Union caused them to withdraw. In 1939, Tokyo judged the Russians weak and vulnerable, and committed an army to test their resolve.
The outcome was a disaster for the Japanese. Gen. Georgy Zhukov launched a counter-offensive, supported by powerful armoured and air forces, which achieved a comprehensive victory. Published casualty figures are unreliable, but probably totalled at least 25,000 on each side. Peace was restored in October, on Moscow’s terms. The strategic consequences were important to the course of the Second World War: the Japanese army set its face against the ‘strike north’ policy, flinching from renewed conflict with the Soviet Union. In 1941 Tokyo signed a neutrality pact with Moscow. Most of Japan’s leaders favoured honouring this, believing that the Western empires in South-East Asia offered softer targets for national expansion. They expected Germany to win the war in Europe. Japanese military attachés in London and Stockholm who reported that the Germans were ill-equipped to launch an invasion of Britain were rebuked by their superiors in Tokyo, to whom such views were unacceptable. Germany’s war in Europe was overwhelmingly responsible for precipitating Japan’s war in Asia: Tokyo would never have dared to attack, but for its conviction that a Hitlerian triumph in the west was imminent.
On 27 September 1940, the Tripartite Pact signed in Berlin between Germany, Italy and Japan promised mutual assistance if any of the parties was attacked by a nation not engaged in the European war. This was a move designed to deter the United States from exerting further pressure on Japan, and it failed. The US, implacably hostile to Japanese imperialism in China, imposed further sanctions. In response, the Japanese committed themselves to execute the ‘strike south’ strategy. They prepared to seize the West’s ill-defended south-east possessions in a series of lightning operations, bludgeoning America into acquiescence by evicting its forces from the western Pacific.
In the middle of 1941, the Japanese military drafted their optimistically titled ‘Operational Plan for ending the war with the US, Britain, the Netherlands and Chiang Kai-shek’. Initially, they intended to ‘await a good opportunity in the European war situation, notably collapse of mainland England, ending of the German–Soviet war and success of our policies towards India’. Emperor Hirohito said, after studying the plan: ‘I understand you are going to do Hong Kong after Malaya starts. Well, what about the foreign concessions in China?’ His Majesty was assured that such European
