The Army service component command of United States Southern Command , its area of responsibility includes 31 countries and 15 areas of special sovereignty in Central and South America and the Caribbean. It is headquartered at Fort Sam Houston . The Sixth Army saw extensive service in the South Pacific during World War II, including in New Britain , New Guinea , and

164-475: A Scientific Panel composed of Robert Oppenheimer , Enrico Fermi , Ernest Lawrence , and Arthur Compton . In a 1 June report, the Committee concluded that the bomb should be used as soon as possible against a war plant surrounded by workers' homes and that no warning or demonstration should be given. The committee's mandate did not include the use of the bomb—its use upon completion was presumed. Following

246-600: A counterbalance to the million-strong Kwantung Army . The Allied submarine campaign and the mining of Japanese coastal waters had largely destroyed the Japanese merchant fleet. With few natural resources, Japan was dependent on raw materials, particularly oil, imported from Manchuria and other parts of the East Asian mainland, and from the conquered territory in the Dutch East Indies . The destruction of

328-552: A protest by scientists involved in the project, in the form of the Franck Report , the Committee re-examined the use of the bomb, posing the question to the Scientific Panel of whether a "demonstration" of the bomb should be used before actual battlefield deployment. In a 21 June meeting, the Scientific Panel affirmed that there was no alternative. Truman played very little role in these discussions. At Potsdam, he

410-430: A purposeful deception predicated upon a desire to play both ends against the middle. While this judgment does not accord with the much-lauded character of Admiral Suzuki, the fact remains that from the moment he became Premier until the day he resigned no one could ever be quite sure of what Suzuki would do or say next. Japanese leaders had always envisioned a negotiated settlement to the war. Their prewar planning expected

492-500: A rapid expansion and consolidation, an eventual conflict with the United States, and finally a settlement in which they would be able to retain at least some new territory they had conquered. By 1945, Japan's leaders were in agreement that the war was going badly, but they disagreed over the best means to negotiate its end. There were two camps: the so-called "peace" camp favored a diplomatic initiative to persuade Joseph Stalin ,

574-462: A theater army headquarters is the army service component command assigned to a geographic combatant command . It is organized, manned and equipped to perform 3 roles: A theater army is responsible for the administration and support of all United States Army forces assigned, attached, under the operational control of a geographic combatant command or transitioning to that area of responsibility (AOR). For example, United States Army Central (Formerly

656-1036: The Army General Staff, and Chief of the Navy General Staff. At the formation of the Suzuki government in April 1945, the council's membership consisted of: All of these positions were nominally appointed by the Emperor and their holders were answerable directly to him. Nevertheless, Japanese civil law from 1936 required that the Army and Navy ministers had to be active duty flag officers from those respective services while Japanese military law from long before that time prohibited serving officers from accepting political offices without first obtaining permission from their respective service headquarters which, if and when granted, could be rescinded at any time. Thus,

738-689: The Eighth Army . On 20 October 1944, X Corps and XXIV Corps , under Sixth Army, invaded Leyte in the Philippines . By December, Leyte was secured, and the Sixth Army was relieved again by Eighth Army to prepare for the invasion of Luzon . As a prelude to that invasion, the island of Mindoro was invaded by the Western Visayan Task Force comprising the 19th and 503rd Regimental Combat Teams. Sixth Army took part in

820-588: The Invasion of Lingayen Gulf on 9 January 1945 with the subordinate units of I and XIV Corps . Sixth Army units fought south until they met up those of Eighth Army advancing from around Manila . Sixth Army then continued to clear the north of Luzon and confronted the Shimbu Group in the Sierra Madres until the end of the war. Sixth Army was to have provided the ground forces for the first phase of

902-563: The Philippines . Postwar it served stateside training army forces until its inactivation during force reduction in 1995. The army was reactivated in 2007. The first iteration of the Sixth Army was authorized by the National Defense Act of 1920 and was originally to be composed of Organized Reserve units primarily from the Seventh, Eighth, and Ninth Corps Areas . The Headquarters and Headquarters Company were constituted in

984-753: The Soviet Union , the United Kingdom , and the United States , represented by Stalin, Winston Churchill (later Clement Attlee ), and Truman respectively. Although the Potsdam Conference was mainly concerned with European affairs, the war against Japan was also discussed in detail. Truman learned of the successful Trinity test early in the conference and shared this information with the British delegation. The successful test caused

1066-661: The Supreme Headquarters Allied Expeditionary Force (SHEAF), coordinating the strategy and operation of multiple service branches . As of 2024, the United States Department of Defense has established 11 of these CCMDs, composed of units from two or more service branches of the United States Armed Forces , and conducts broad and continuing missions. For any such CCMDs that include units of

Sixth Army returned to the United States in 1946, and was headquartered at the Presidio of San Francisco . After the war, Sixth Army took responsibility for training of Army forces from part of the continental United States. It was eventually inactivated in June 1995 due to force reductions. In 2007 it

1230-595: The 1970s. The role of the atomic bombings in Japan's unconditional surrender, and the ethics of the two attacks, is debated . The state of war formally ended when the Treaty of San Francisco came into force on 28 April 1952. Four more years passed before Japan and the Soviet Union signed the Soviet–Japanese Joint Declaration of 1956 , which formally brought an end to their state of war. By 1945,

1312-614: The Allies, the Soviets responded with delaying tactics to encourage the Japanese without promising anything. Satō finally met with Soviet Foreign Minister Vyacheslav Molotov on 11 July, but without result. On 12 July, Tōgō directed Satō to tell the Soviets that: His Majesty the Emperor, mindful of the fact that the present war daily brings greater evil and sacrifice upon the peoples of all the belligerent powers, desires from his heart that it may be quickly terminated. But so long as England and

1394-420: The Allies. His own comments at the conference of senior statesmen gave no hint that he favored any early cessation of the war ... Suzuki's selections for the most critical cabinet posts were, with one exception, not advocates of peace either. After the war, Suzuki and others from his government and their apologists claimed they were secretly working towards peace, and could not publicly advocate it. They cite

1476-548: The American delegation to reconsider the necessity and wisdom of Soviet participation, for which the U.S. had lobbied hard at the Tehran and Yalta Conferences . The United States prioritized shortening the war and reducing American casualties—Soviet intervention seemed likely to do both, but at the cost of possibly allowing the Soviets to capture territory beyond that which had been promised to them at Tehran and Yalta, and causing

1558-713: The Conduct of the War," which stated that the Japanese people would fight to extinction rather than surrender. This policy was adopted by the Big Six on 6 June. (Tōgō opposed it, while the other five supported it.) Documents submitted by Suzuki at the same meeting suggested that, in the diplomatic overtures to the USSR, Japan adopt the following approach: It should be clearly made known to Russia that she owes her victory over Germany to Japan, since we remained neutral, and that it would be to

1640-596: The Emperor, were not acceptable to the Japanese leadership. On 5 April, the Soviet Union gave the required 12 months' notice that it would not renew the five-year Soviet–Japanese Neutrality Pact (which had been signed in 1941 following the Nomonhan Incident ). Unknown to the Japanese, at the Tehran Conference in November–December 1943, it had been agreed that the Soviet Union would enter

1722-667: The Fourth Army, the General Headquarters Reserve, or demobilized. The Sixth United States Army was activated in January 1943, commanded by Lieutenant General Walter Krueger . Under the code name Alamo Force , it assumed control of the majority of US Army units involved in Operation Cartwheel , the campaign to isolate and neutralize the Japanese base at Rabaul in New Britain . Following

1804-511: The Japanese Army and Navy effectively held a legal right to nominate (or refuse to nominate) their respective ministers, in addition to the effective right to order their respective ministers to resign their posts. Strict constitutional convention dictated (as it technically still does today) that a prospective Prime Minister could not assume the premiership, nor could an incumbent Prime Minister remain in office, if he could not fill all of

1886-491: The Japanese Imperial High Command planned an all-out defense of Kyūshū codenamed Operation Ketsugō . This was to be a radical departure from the defense in depth plans used in the invasions of Peleliu , Iwo Jima , and Okinawa . Instead, everything was staked on the beachhead; more than 3,000 kamikazes would be sent to attack the amphibious transports before troops and cargo were disembarked on

1968-422: The Japanese concept of haragei —"the art of hidden and invisible technique"—to justify the dissonance between their public actions and alleged behind-the-scenes work. However, many historians reject this. Robert J. C. Butow wrote: Because of its very ambiguity, the plea of haragei invites the suspicion that in questions of politics and diplomacy a conscious reliance upon this 'art of bluff' may have constituted

2050-610: The Japanese had suffered a string of defeats for nearly two years in the South West Pacific , India , the Marianas campaign , and the Philippines campaign . In July 1944, following the loss of Saipan , General Hideki Tōjō was replaced as prime minister by General Kuniaki Koiso , who declared that the Philippines would be the site of the decisive battle. After the Japanese loss of the Philippines, Koiso in turn

2132-460: The Japanese home islands. General Marshall supported the entry of the Red Army , believing that doing so would cause Japan to capitulate. McCloy had told Stimson that there were no more Japanese cities to be bombed and wanted to explore other options of bringing about a surrender. He suggested a political solution and asked about warning the Japanese of the atomic bomb. James Byrnes, who would become

2214-554: The Japanese merchant fleet, combined with the strategic bombing of Japanese industry , had wrecked Japan's war economy. Production of coal, iron, steel, rubber, and other vital supplies was only a fraction of that before the war. As a result of the losses it had suffered, the Imperial Japanese Navy (IJN) had ceased to be an effective fighting force. Following a series of raids on the Japanese shipyard at Kure ,

2296-626: The Organized Reserve on 15 October 1921 and allotted to the Seventh Corps Area. Little Rock , Arkansas , was designated as the army headquarters upon organization, but the unit was never organized at that location. The Headquarters Company was initiated 13 October 1922 at Little Rock. Little Rock remained the Sixth Army’s headquarters location upon the event of its activation until 25 February 1924 when St. Louis , Missouri ,

2378-664: The South to repel the inevitable US attack, thus leaving its Northern islands vulnerable to Soviet invasion. Soviet Foreign Minister Vyacheslav Molotov , in Moscow, and Yakov Malik , Soviet ambassador in Tokyo, went to great lengths to assure the Japanese that "the period of the Pact's validity has not ended". At a series of high-level meetings in May, the Big Six first seriously discussed ending

2460-684: The Soviet Pacific coastline— Vladivostok in particular—could be blockaded by air and sea from Sakhalin island and the Kurile Islands . Acquiring these territories, thus guaranteeing free access to the Soya Strait , was their primary objective. Secondary objectives were leases for the Chinese Eastern Railway , Southern Manchuria Railway , Dairen , and Port Arthur . To this end, Stalin and Molotov strung out

2542-469: The Soviet Union could be persuaded to act as an agent for Japan in negotiations with the United States and Britain. After several years of preliminary research, President Franklin D. Roosevelt had authorized the initiation of a massive, top-secret project to build atomic bombs in 1942. The Manhattan Project , under the authority of Major General Leslie R. Groves Jr. employed hundreds of thousands of American workers at dozens of secret facilities across

2624-463: The Soviets into the war against Japan. Tōgō had been outspoken about ending the war quickly. As a result of these meetings, he was authorized to approach the Soviet Union, seeking to maintain its neutrality, or (despite the very remote probability) to form an alliance. In keeping with the custom of a new government declaring its purposes, following the May meetings the Army staff produced a document, "The Fundamental Policy to Be Followed Henceforth in

In addition, in the event that the overall combatant commander creates a subordinate unified command within their CCMD, the Department of the Army will form a matching Army component headquarters. In matching, the Secretary of the Army also has the authority to redirect service responsibilities outside of Army Service Command Component channels (to one of the other service branches attached to

2870-531: The US and the UK at the Tehran and Yalta Conferences . On 6 August 1945, at 8:15 am local time, the United States detonated an atomic bomb over the Japanese city of Hiroshima . Sixteen hours later, American President Harry S. Truman called again for Japan's surrender, warning them to "expect a rain of ruin from the air, the like of which has never been seen on this earth." Late on 8 August 1945, in accordance with

2952-732: The United States has sustained heavy losses" in Operation Ketsugō . In June, the Emperor lost confidence in the chances of achieving a military victory. The Battle of Okinawa was lost, and he learned of the weakness of the Japanese army in China, of the Kwantung Army in Manchuria, of the navy, and of the army defending the Home Islands. The Emperor received a report by Prince Higashikuni from which he concluded that "it

3034-610: The United States insist upon unconditional surrender, the Japanese Empire has no alternative but to fight on with all its strength for the honor and existence of the Motherland. The Emperor proposed sending Prince Konoe as a special envoy, although he would be unable to reach Moscow before the Potsdam Conference . Satō advised Tōgō that in reality, "unconditional surrender or terms closely equivalent thereto"

3116-537: The United States, and on 16 July 1945, the first prototype weapon was detonated during the Trinity nuclear test . As the project neared its conclusion, American planners began to consider the use of the bomb. In keeping with the Allies' overall strategy of securing final victory in Europe first, it had initially been assumed that the first atomic weapons would be allocated for use against Germany. However, by this time it

Hours later, the United States dropped a second atomic bomb , on the Japanese city of Nagasaki . Emperor Hirohito ordered the Supreme Council for the Direction of the War to accept

3280-519: The advantage of the Soviets to help Japan maintain her international position, since they have the United States as an enemy in the future. On 9 June, the Emperor's confidant Marquis Kōichi Kido wrote a "Draft Plan for Controlling the Crisis Situation," warning that by the end of the year Japan's ability to wage modern war would be extinguished and the government would be unable to contain civil unrest. "... We cannot be sure we will not share

If this did not drive the Allies away, they planned to send another 3,500 kamikazes along with 5,000 Shin'yō suicide motorboats and the remaining destroyers and submarines—"the last of the Navy's operating fleet"—to the beach. If the Allies had fought through this and successfully landed on Kyūshū, 3,000 planes would have been left to defend the remaining islands, although Kyūshū would be "defended to

Emperor Hirohito and Lord Keeper of the Privy Seal Kōichi Kido also were present at some meetings, following the Emperor's wishes. As Iris Chang reports, "... the Japanese deliberately destroyed, hid or falsified most of their secret wartime documents before General MacArthur arrived." For

The theater army commander remains responsible to the Department of the Army for Service-specific requirements. This falls under the ADCON chain of authority Responsibilities of a Service component are determined from Title 10 ; DODD 5101.1; DA Memo 1-10; and combatant commander’s daily operational requirements. These responsibilities may include: Additionally,

3690-409: The completion of Cartwheel, Sixth Army joined the Australian Army and other US forces on the north coast of New Guinea . Similar in conception to the island hopping operations of the central Pacific, the object of the attacks was to land, establish a garrison and airfield which could support the next strike, and then move on. In September 1944, Sixth Army was relieved from operations in New Guinea by

3772-422: The decisive naval Battle of Tsushima . In February 1945, Prince Fumimaro Konoe gave Emperor Hirohito a memorandum analyzing the situation, and told him that if the war continued, the imperial family might be in greater danger from an internal revolution than from defeat. According to the diary of Grand Chamberlain Hisanori Fujita , the Emperor, looking for a decisive battle ( tennōzan ), replied that it

Kido proposed that the Emperor take action, by offering to end the war on "very generous terms." Kido proposed that Japan withdraw from the formerly European colonies it had occupied provided they were granted independence and also proposed that Japan recognize

3936-441: The formerly German islands in the Pacific and even Manchukuo . With the Emperor's authorization, Kido approached several members of the Supreme Council , the "Big Six." Tōgō was very supportive. Suzuki and Admiral Mitsumasa Yonai , the Navy minister , were both cautiously supportive; each wondered what the other thought. General Korechika Anami , the Army minister , was ambivalent, insisting that diplomacy must wait until "after

4018-479: The government as well, are convinced that our war strength still can deliver considerable blows to the enemy, we are unable to feel absolutely secure peace of mind ... Please bear particularly in mind, however, that we are not seeking the Russians' mediation for anything like an unconditional surrender. In reply, Satō clarified: It goes without saying that in my earlier message calling for unconditional surrender or closely equivalent terms, I made an exception of

4100-627: The independence of the Philippines , which Japan had already mostly lost control of and to which it was well known that the U.S. had long been planning to grant independence. Finally, Kido proposed that Japan disarm provided this not occur under Allied supervision and that Japan for a time be "content with minimum defense." Kido's proposal did not contemplate Allied occupation of Japan, prosecution of war criminals or substantial change in Japan's system of government, nor did Kido suggest that Japan might be willing to consider relinquishing territories acquired prior to 1937 including Formosa , Karafuto , Korea ,

4182-447: The intended recipients. Fearing heavy casualties, the Allies wished for Soviet entry in the Pacific War at the earliest possible date. Roosevelt had secured Stalin's promise at Cairo , which was re-affirmed at Yalta . That outcome was greatly feared in Japan. Security concerns dominated Soviet decisions concerning the Far East. Chief among these was gaining unrestricted access to the Pacific Ocean . The year-round ice-free areas of

4264-412: The last" regardless. The strategy of making a last stand at Kyūshū was based on the assumption of continued Soviet neutrality. Japanese policy-making centered on the Supreme Council for the Direction of the War (created in 1944 by earlier Prime Minister Kuniaki Koiso ), the so-called "Big Six"—the Prime Minister , Minister of Foreign Affairs , Minister of the Army , Minister of the Navy , Chief of

4346-442: The leader of the Soviet Union, to mediate a settlement between the Allies and Japan; and the hardliners who favored fighting one last "decisive" battle that would inflict so many casualties on the Allies that they would be willing to offer more lenient terms. Both approaches were based on Japan's experience in the Russo–Japanese War , forty years earlier, which consisted of a series of costly but largely indecisive battles, followed by

4428-479: The most part, Suzuki's military-dominated cabinet favored continuing the war. For the Japanese, surrender was unthinkable—Japan had never been successfully invaded or lost a war in its history. Only Mitsumasa Yonai, the Navy minister, was known to desire an early end to the war. According to historian Richard B. Frank : Although Suzuki might indeed have seen peace as a distant goal, he had no design to achieve it within any immediate time span or on terms acceptable to

4510-421: The negotiations with the Japanese, giving them false hope of a Soviet-mediated peace. At the same time, in their dealings with the United States and Britain, the Soviets insisted on strict adherence to the Cairo Declaration, re-affirmed at the Yalta Conference, that the Allies would not accept separate or conditional peace with Japan. The Japanese would have to surrender unconditionally to all the Allies. To prolong

4592-448: The new Secretary of State on 3 July, wanted to use it as quickly as possible without warning and without letting the Soviets know beforehand. On 30 June, Tōgō told Naotake Satō , Japan's ambassador in Moscow, to try to establish "firm and lasting relations of friendship." Satō was to discuss the status of Manchuria and "any matter the Russians would like to bring up." Well aware of the overall situation and cognizant of their promises to

4674-400: The only major warships in somewhat fighting order were six aircraft carriers, four cruisers, and one battleship, of which many were heavily damaged and none could be fueled adequately. Although 19 destroyers and 38 submarines were still operational, their use was also limited by the lack of fuel. Faced with the prospect of an invasion of the Home Islands, starting with Kyūshū , and

4756-408: The prospect of a Soviet invasion of Manchuria—Japan's last source of natural resources—the War Journal of the Imperial Headquarters concluded in 1944: We can no longer direct the war with any hope of success. The only course left is for Japan's one hundred million people to sacrifice their lives by charging the enemy to make them lose the will to fight. As a final attempt to stop the Allied advances,

4838-435: The publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be willing to mediate, the Soviets were covertly preparing to attack Japanese forces in Manchuria and Korea (in addition to South Sakhalin and the Kuril Islands ) in fulfillment of promises they had secretly made to

4920-416: The question of preserving [the imperial family]. On 21 July, speaking in the name of the cabinet, Tōgō repeated: With regard to unconditional surrender we are unable to consent to it under any circumstances whatever. ... It is in order to avoid such a state of affairs that we are seeking a peace, ... through the good offices of Russia. ... it would also be disadvantageous and impossible, from

5002-403: The standpoint of foreign and domestic considerations, to make an immediate declaration of specific terms. American cryptographers had broken most of Japan's codes, including the Purple code used by the Japanese Foreign Office to encode high-level diplomatic correspondence. As a result, messages between Tokyo and Japan's embassies were provided to Allied policy-makers nearly as quickly as to

ASCCs also server administrative control for some of its functions, this is also typically true among Reserve Component forces. Shared administrative control also applies to direct reporting units of the Army that typically perform single or unique functions. Four types of command authority can be distinguished: According to U.S. Army Doctrine ,

After several more days of behind-the-scenes negotiations and a failed coup d'état , Emperor Hirohito gave a recorded radio address across the Empire on 15 August announcing the surrender of Japan to the Allies. On 28 August, the occupation of Japan led by the Supreme Commander for the Allied Powers began. The surrender ceremony

Surrender of Japan The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, ending the war . By the end of July 1945, the Imperial Japanese Navy (IJN) was incapable of conducting major operations and an Allied invasion of Japan

5494-448: The top of the list were Kyoto , Hiroshima , Yokohama , Kokura , and Niigata . Ultimately, Kyoto was removed from the list at the insistence of Secretary of War Henry L. Stimson , who had visited the city on his honeymoon and knew of its cultural and historical significance. Although the previous Vice President , Henry A. Wallace , had been involved in the Manhattan Project since the beginning, his successor, Harry S. Truman ,

5576-430: The war against Japan once Germany was defeated. At the Yalta Conference in February 1945, the United States had made substantial concessions to the Soviets to secure a promise that they would declare war on Japan within three months of the surrender of Germany. Although the five-year Neutrality Pact did not expire until 5 April 1946, the announcement caused the Japanese great concern, because Japan had amassed its forces in

5658-524: The war, but none of them on terms that would have been acceptable to the Allies. Because anyone openly supporting Japanese surrender risked assassination by zealous army officers, the meetings were closed to anyone except the Big Six, the Emperor, and the Privy Seal. No second or third-echelon officers could attend. At these meetings, despite the dispatches from Japanese ambassador Satō in Moscow, only Foreign Minister Tōgō realized that Roosevelt and Churchill might have already made concessions to Stalin to bring

This would give the Soviets time to complete the transfer of their troops from the Western Front to the Far East, and conquer Manchuria , Inner Mongolia , northern Korea , South Sakhalin , the Kuriles , and possibly Hokkaidō (starting with a landing at Rumoi ). The leaders of the major Allied powers met at the Potsdam Conference from 16 July to 2 August 1945. The participants were

Other neutral nations, such as Switzerland , Sweden , and the Vatican City , were known to be willing to play a role in making peace, but they were so small they were believed unable to do more than deliver the Allies' terms of surrender and Japan's acceptance or rejection. The Japanese hoped that

Moreover, in response to Molotov's requests for specific proposals, Satō suggested that Tōgō's messages were not "clear about the views of the Government and the Military with regard to the termination of the war," thus questioning whether Tōgō's initiative was supported by the key elements of Japan's power structure. On 17 July, Tōgō responded: Although the directing powers, and

Its subordinate units were reassigned to

Allied civilians and military personnel alike celebrated V-J Day , the end of the war; however, isolated soldiers and personnel from Japan's forces throughout Asia and the Pacific refused to surrender for months and years afterwards, some into
