When war broke out in Europe in September 1939, the Japanese, despite a series of victorious battles, had still not brought their war in China to an end: on the one hand, the Japanese strategists had made no plans to cope with the guerrilla warfare pursued by the Chinese; on the other, the Japanese commanders in the field often disregarded the orders of the supreme command at the Imperial headquarters and occupied more Chinese territory than they had been ordered to take. Half of the Japanese Army was thus still tied down in China when the commitment of Great Britain and France to war against Germany opened up the prospect of wider conquests for Japan in Southeast Asia and in the Pacific. Japan’s military ventures in China proper were consequently restricted rather more severely henceforth.
The German victories over the Netherlands and France in the summer of 1940 further encouraged the Japanese premier, Prince Konoe, to look southward at those defeated powers’ colonies and also, of course, at the British and U.S. positions in the Far East. The island archipelago of the Dutch East Indies (now Indonesia) along with French Indochina and British-held Malaya contained raw materials (tin, rubber, petroleum) that were essential to Japan’s industrial economy, and if Japan could seize these regions and incorporate them into the empire, it could make itself virtually self-sufficient economically and thus become the dominant power in the Pacific Ocean. Since Great Britain, single-handedly, was confronting the might of the Axis in Europe, the Japanese strategists had to reckon, primarily, with the opposition of the United States to their plans for territorial aggrandizement. When Japanese troops entered northern Indochina in September 1940 (in pursuance of an agreement extorted in August from the Vichy government of France), the United States uttered a protest. Germany and Italy, by contrast, recognized Japan as the leading power in the Far East by concluding with it the Tripartite, or Axis, Pact of September 27, 1940: negotiated by Japanese foreign minister Matsuoka Yosuke, the pact pledged its signatories to come to one another’s help in the event of an attack “by a power not already engaged in war.” Japan also concluded a neutrality pact with the U.S.S.R. on April 13, 1941.
On July 2, 1941, the Imperial Conference decided to press the Japanese advance southward even at the risk of war with Great Britain and the United States; and this policy was pursued even when Matsuoka was relieved of office a fortnight later. On July 26, in pursuance of a new agreement with Vichy France, Japanese forces began to occupy bases in southern Indochina.
This time the United States reacted vigorously, not only freezing Japanese assets under U.S. control but also imposing an embargo on supplies of oil to Japan. Dismay at the embargo drove the Japanese naval command, which had hitherto been more moderate than the army, into collusion with the army’s extremism. When negotiations with the Dutch of Indonesia for an alternative supply of oil produced no satisfaction, the Imperial Conference on September 6, at the high command’s insistence, decided that war must be undertaken against the United States and Great Britain unless an understanding with the United States could be reached in a few weeks’ time.
General Tōjō Hideki, who succeeded Konoe as premier in mid-October 1941, continued the already desperate talks. The United States, however, persisted in making demands that Japan could not concede: renunciation of the Tripartite Pact (which would have left Japan diplomatically isolated); the withdrawal of Japanese troops from China and from Southeast Asia (a humiliating retreat from an overt commitment of four years’ standing); and an open-door regime for trade in China. When Cordell Hull, the U.S. secretary of state, on November 26, 1941, sent an abrupt note to the Japanese bluntly requiring them to evacuate China and Indochina and to recognize no Chinese regime other than that of Chiang Kai-shek, the Japanese could see no point in continuing the talks. (See Sidebar: Pearl Harbor and the “Back Door to War” Theory.)
Since peace with the United States seemed impossible, Japan set in motion its plans for war, which would now necessarily be waged not only against the United States but also against Great Britain (the existing war effort of which depended on U.S. support and the Far Eastern colonies of which lay within the orbit of the projected Japanese expansion) and against the Dutch East Indies (the oil of which was essential to Japanese enterprises, even apart from geopolitical considerations).
The evolving Japanese military strategy was based on the peculiar geography of the Pacific Ocean and on the relative weakness and unpreparedness of the Allied military presence in that ocean. The western half of the Pacific is dotted with many islands, large and small, while the eastern half of the ocean is, with the exception of the Hawaiian Islands, almost devoid of landmasses (and hence of usable bases). The British, French, American, and Dutch military forces in the entire Pacific region west of Hawaii amounted to only about 350,000 troops, most of them lacking combat experience and being of disparate nationalities. Allied air power in the Pacific was weak and consisted mostly of obsolete planes. If the Japanese, with their large, well-equipped armies that had been battle-hardened in China, could quickly launch coordinated attacks from their existing bases on certain Japanese-mandated Pacific islands, on Formosa (Taiwan), and from Japan itself, they could overwhelm the Allied forces, overrun the entire western Pacific Ocean as well as Southeast Asia, and then develop those areas’ resources to their own military-industrial advantage. If successful in their campaigns, the Japanese planned to establish a strongly fortified defensive perimeter extending from Burma in the west to the southern rim of the Dutch East Indies and northern New Guinea in the south and sweeping around to the Gilbert and Marshall islands in the southeast and east. The Japanese believed that any American and British counteroffensives against this perimeter could be repelled, after which those nations would eventually seek a negotiated peace that would allow Japan to keep her newly won empire.
Until the end of 1940 the Japanese strategists had assumed that any new war to be waged would be against a single enemy. When it became clear, in 1941, that the British and the Dutch as well as the Americans must be attacked, a new and daring war plan was successfully sponsored by the commander in chief of the Combined Fleet, Admiral Yamamoto Isoroku.
Yamamoto’s plan prescribed two operations, together involving the whole strength of his navy, which was composed of the following ships: 10 battleships, six regular aircraft carriers, four auxiliary carriers, 18 heavy cruisers, 20 light cruisers, 112 destroyers, 65 submarines, and 2,274 combat planes. The first operation, to which all six regular aircraft carriers, two battleships, three cruisers, and 11 destroyers were allocated, was to be a surprise attack, scheduled for December 7 (December 8 by Japanese time), on the main U.S. Pacific Fleet in its base at Pearl Harbor in the Hawaiian Islands. The rest of the Japanese Navy was to support the army in the “Southern Operation”: 11 infantry divisions and seven tank regiments, assisted by 795 combat planes, were to undertake two drives, one from Formosa through the Philippines, the other from French Indochina and Hainan Island through Malaya, so as to converge on the Dutch East Indies, with a view to the capture of Java as the culmination of a campaign of 150 days—during which, moreover, Wake Island, Guam, the Gilbert Islands, and Burma should also have been secured as outer bastions, besides Hong Kong.
Pearl Harbor and the Japanese expansion, to July 1942
In accordance with Yamamoto’s plan, the aircraft carrier strike force commanded by Admiral Nagumo Chuichi sailed eastward undetected by any U.S. reconnaissance until it had reached a point 275 miles north of Hawaii. From there, on Sunday, December 7, 1941, a total of about 360 aircraft, composed of dive-bombers, torpedo bombers, and a few fighters, was launched in two waves in the early morning at the giant U.S. naval base at Pearl Harbor. The base at that time was accommodating 70 U.S. fighting ships, 24 auxiliaries, and some 300 planes. The Americans were taken completely by surprise, and all eight battleships in the harbour were hit (though six were eventually repaired and returned to service); three cruisers, three destroyers, a minelayer, and other vessels were damaged; more than 180 aircraft were destroyed and others damaged (most while parked at airfields); and more than 2,330 troops were killed and over 1,140 wounded. Japanese losses were comparatively small. The Japanese attack failed in one crucial respect, however; the Pacific Fleet’s three aircraft carriers were at sea at the time of the attack and escaped harm, and these were to become the nucleus of the United States’ incipient naval defense in the Pacific. Pearl Harbor’s shore installations and oil-storage facilities also escaped damage. The Pearl Harbor attack, unannounced beforehand by the Japanese as it was, unified the American public and swept away any remaining support for American neutrality in the war. On December 8 the U.S. Congress declared war on Japan with only one dissenting vote.
On the day of the attack, December 8 by local time, Formosa-based Japanese bombers struck Clark and Iba airfields in the Philippines, destroying more than 50 percent of the U.S. Army’s Far East aircraft; and, two days later, further raids destroyed not only more U.S. fighters but also Cavite Naval Yard, likewise in the Philippines. Part of the U.S. Asiatic Fleet, however, had already gone south in November; and the surviving major ships and bomber aircraft, which were vulnerable for lack of fighter protection, were withdrawn in the next fortnight to safety in bases in Java and Australia.
Japanese forces began to land on the island of Luzon in the Philippines on December 10. The main assault, consisting of the bulk of one division, was made at Lingayen Gulf, 100 miles north-northwest of Manila, on December 22, and a second large landing took place south of Manila two days later. Manila itself fell unopposed to the Japanese on January 2, 1942, but by that time the U.S. and Filipino forces under General Douglas MacArthur were ready to hold Bataan Peninsula (across the bay from Manila) and Corregidor Island (in the bay). The Japanese attack on Bataan was halted initially, but it was reinforced in the following eight weeks. MacArthur was ordered to Australia on March 11, leaving Bataan’s defense to Lieutenant General Jonathan M. Wainwright. The latter and his men surrendered on April 9; Corregidor fell in the night of May 5–6; and the southern Philippines capitulated three days later.
Japanese bombers had already destroyed British air power at Hong Kong on December 8, 1941, and the British and Canadian defenders surrendered to the ground attack from the Kowloon Peninsula (the nearest mainland) on December 25. To secure their flank while pushing southward into Malaya, the Japanese also occupied Bangkok on December 9 and Victoria Point in southernmost Burma on December 16. The Japanese landings in Malaya, from December 8 onward, accompanied as they were by air strikes, overwhelmed the small Australian and Indian forces; and the British battleship Prince of Wales and the battle cruiser Repulse, sailing from Singapore to cut Japanese communications, were sunk by Japanese aircraft on December 10. By the end of January 1942, two Japanese divisions, with air and armoured support, had occupied all Malaya except Singapore Island. In Burma, meanwhile, other Japanese troops had taken Moulmein and were approaching Rangoon and Mandalay.
On the eastern perimeter of the war zone, the Japanese had bombed Wake Island on December 8, attempted to capture it on December 11, and achieved a landing on December 23, quickly subduing the garrison. Guam had already fallen on December 10. Having also occupied Makin and Tarawa in the Gilbert Islands in the first days of the war, the Japanese successfully attacked Rabaul, the strategic base on New Britain (now part of Papua New Guinea), on January 23, 1942.
A unified American–British–Dutch–Australian Command, ABDACOM, under Wavell, responsible for holding Malaya, Sumatra, Java, and the approaches to Australia, became operative on January 15, 1942; but the Japanese had already begun their advance on the oil-rich Dutch East Indies. They occupied Kuching (December 17), Brunei Bay (January 6), and Jesselton (January 11), on the northern coast of Borneo, as well as Tarakan Island (off northeastern Borneo) and points on Celebes. Balikpapan (on Borneo’s east coast) and Kendari (in southeastern Celebes) fell to the Japanese on January 24, 1942, Amboina on February 4, Makasar City (in southwestern Celebes) on February 8, and Bandjarmasin (in southern Borneo) on February 16. Bali was invaded on February 18, and by February 24 the Japanese were also in possession of Timor.
