Реферат: The U.S. Army Campaigns of World War II

First, a pocket of German resistance at Colmar had to be eliminated. Eisenhower assigned five additional U.S. divisions and 10,000 service troops to the effort. The Franco-American attack against the pocket began on 20 January and was over by early February. Meantime, the Canadian First Army cleared the area between the Maas and Rhine Rivers. At the same time, the First Army advanced and finally seized the Roer River dams but found that the Germans had destroyed the controls. The resultant flooding delayed the Ninth Army's advance by two weeks. That attack finally began in late February and linked up with the Canadians, cutting off German forces facing the British. Meanwhile, the First Army's drive to the Rhine culminated in the capture of Cologne and on 7 March the seizure of an intact bridge at the town of Remagen.

As American divisions poured into the bridgehead, the Third and Seventh Armies launched coordinated attacks to the south. On the 22d and the 25th, Third Army troops made assault crossings of the Rhine. On 23 March the British Second Army and the U.S. Ninth Army staged massive crossings in the Rees-Wesel-Dinslaken area, supported by the largest airborne landings of the war, while the Seventh Army crossed on the 26th near Worms. Now Allied columns fanned out across Germany, overrunning isolated pockets of resistance. While Montgomery's forces drove northward toward the great German ports of Bremen, Hamburg, and Luebeck, the Ninth Army advanced along the axis Muenster-Magdeburg. Ninth and First Army troops met on 1 April, encircling the industrial region of the Ruhr and capturing 325,000 prisoners. The First Army continued eastward toward Kassel and Leipzig while the Third Army rolled through Frankfurt, Eisenach, and Erfurt toward Dresden, then southward toward Czechoslovakia and Austria. The Sixth Army Group advanced into Bavaria toward Munich and Salzburg, denying the Germans a last-ditch defense in the Bavarian or Austrian Alps. Germany was shattered.

Nevertheless, Eisenhower resisted British pressure to drive on to Berlin. He saw no point in taking casualties to capture ground that, in line with earlier agreements between Allied leaders, would have to be relinquished to the Soviets once hostilities ceased. His objective remained to capture or destroy the remnants of the German armed forces. The Soviets massed 1.2 million men and 22,000 pieces of artillery and on 16 April began their assault upon the city. As that battle raged, British, American, and Soviet forces neared previously negotiated stop lines along the Elbe and Mulde Rivers. The First Army made contact with Soviet troops on 25 April around Torgau. Meanwhile, as the Third Army entered Czechoslovakia and British troops reached the Baltic, the Russians moved through the streets of Berlin. On 30 April 1945, Hitler committed suicide in a bunker beneath the ruins of his capitol.

German forces in Italy surrendered effective 2 May and those in the Netherlands, northwestern Germany, and Denmark on 4 May. Patrols of the U.S. Seventh Army driving eastward through Austria and the Fifth Army driving north from Italy met near the Brenner Pass. On 7 May the German High Command surrendered all its forces unconditionally, and 8 May was officially proclaimed V-E Day. Though peace had come to Europe, one of the most culturally and economically advanced areas of the globe lay in ruins. Germany, the industrial engine of the Continent, lay prostrate, occupied by British, French, American, and Soviet troops. Britain, exhausted by its contribution to the victory, tottered near economic collapse, while France was totally dependent on the United States. The Soviet Union had suffered in excess of 20 million casualties and untold devastation, but its armed forces remained powerful and its intentions obscure. To the victory in western Europe and Italy, the United States had contributed 68 divisions, 15,000 combat aircraft, well over 1 million tanks and motor vehicles, and 135,000 dead. The country now turned its focus to a war a half a world away and to the defeat of Japan in the Pacific.

The Pacific War

Even before Pearl Harbor, President Franklin D. Roosevelt and the American military chiefs had agreed on a common strategy with Great Britain: Germany, the most powerful and dangerous of the Axis powers, must be defeated first. Only enough military resources would be devoted to the Pacific to hold the Japanese west of an Alaska-Hawaii-Panama defensive line.

Competition for limited resources between the Allied commanders of the European and Pacific theaters was actually less intense than might have been expected. The Pacific was a naval war, and little U.S. offensive naval power was required in the Atlantic besides landing craft. Aside from the U-boats, the Germans posed no threat in Atlantic waters. U-boat defense primarily required many small, fast escort vessels. Then too, almost the entire British Navy was deployed in the Atlantic. Thus, American offensive naval power--especially the fast carrier task forces--could be committed to the Pacific war.

More than distance separated the two wars; they differed fundamentally in strategy and command and in the character of the fighting. In Europe the war was planned and conducted in combination with powerful Allies. Strategic decisions had to be argued and agreed to by the American and British chiefs of staff, and, on occasion, even by President Roosevelt and Prime Minister Winston Churchill. Operational planning was conducted, at least at the higher levels, by combined Anglo-American staffs. In the Pacific the United States also had Allies--Australia and New Zealand. Yet the ratio of U.S. to Allied forces was much higher there than in Europe, and in consequence strategy and planning were almost wholly in American hands.

Eisenhower, the Supreme Commander in Europe, had no counterpart in the Pacific. From the beginning of the war, rivalry between the Army and the Navy marked the conflict. The two services competed for command, territory, and resources. In the vast Pacific, an ocean dotted with thousands of coral islands, there should have been ample room for both. But interservice rivalries and great distances prevented a single unified commander from being named, until General Douglas MacArthur became Supreme Commander,

Allied Powers (SCAP), in the last days of the war. Instead, the Pacific was divided into area commands. The two most important were MacArthur's Southwest Pacific Area (SWPA) and Admiral Chester Nimitz's Pacific Ocean Areas (POA). POA, in turn, was subdivided into North Pacific, Central Pacific, and South Pacific commands. Nimitz personally retained command of the Central Pacific.

Fighting in the Pacific was unlike fighting in Europe. The campaigns in Europe were characterized by huge ground forces driving overland into the heart of the enemy's country. Both in MacArthur's SWPA and Nimitz's POA, the Pacific war was a seemingly endless series of amphibious landings and island-hopping campaigns where naval power, air power, and shipping, rather than large and heavy ground forces, were of paramount importance.

Yet for the soldiers and marines who assaulted the countless beaches, the Pacific war was even more brutal and deadly than the war in Europe. Japanese defenders always dug in, reinforced their bunkers with coconut logs, and fought until they were killed. They almost never surrendered. On Betio in the Tarawa Atoll in November 1943 the marines suffered 3,301 casualties, including 900 killed in action, for a bit of coral 3 miles long and 800 yards wide. At Iwo Jima in February and March 1945 the marines lost almost 6,000 dead and over 17,000 wounded and fought for five weeks to take an island less than five miles long. At Iwo no battalion suffered fewer than 50 percent casualties, and many sustained even higher losses. In the southwest Pacific, MacArthur's casualties were proportionately fewer. Fighting on the larger land masses of New Guinea and the Philippines, he had more room to maneuver, and he could almost always "hit 'em where they ain't."

The history of the war in the Pacific falls neatly into three periods. The first six months of the war, from December 1941 to May 1942, were a time of unbroken Japanese military victory. At the-height of Japanese expansion in mid-1942, the tide turned. The period from mid-1942 to mid-1943 saw Japanese strategic thrusts into the south and central Pacific blunted by the carrier battles of the Coral Sea (May 1942) and Midway (June 1942). Limited U.S. offensives in the Solomons and in the Papuan area of eastern New Guinea were launched in the last months of 1942. Both offensives were begun on a shoestring, and both came close to failure. Yet they represented the end of defeat in the Pacific and the first tentative steps toward victory. Those steps became great leaps in 1944 and 1945. Two amphibious offensives developed, as MacArthur advanced across the northern coast of New Guinea into the Philippines and Nimitz island-hopped 2,000 miles across the central Pacific from the Gilbert Islands to Okinawa.

Japan on the Offensive

Japan, largely devoid of natural resources to-feed its industries, looked overseas for supplies of strategic materials such as ores and petroleum. Before 1939 the United States was Japan's major supplier. But President Roosevelt and Secretary of State Cordell Hull shut off American supplies in an effort to force the Japanese to end hostilities against China. The Japanese had long coveted the resource-rich British and Dutch colonies of Southeast Asia, and as the U.S. trade embargo tightened, the Japanese increasingly looked southward for raw materials and strategic resources.

Only the United States stood in Japan's path. The U.S. Pacific Fleet at Pearl Harbor was the only force capable of challenging Japan's navy, and American bases in the Philippines could threaten lines of communications between the Japanese home islands and the East Indies. Every oil tanker heading for Japan would have to pass by American-held Luzon. From these needs and constraints, Japan's war plans emerged. First, its navy would neutralize the American fleet with a surprise attack on Pearl Harbor. Japan would also seize America's central Pacific bases at Guam and Wake islands and invade the Philippines. With American naval power crippled, Japan's military would be free to seize Burma, Malaya, Singapore, and the Dutch East Indies in a series of rapid amphibious operations. Japan would then establish a defensive ring around its newly conquered empire by fortifying islands in the south and the central Pacific. Japan's leaders were convinced that Americans, once involved in the European war, would be willing to negotiate peace in the Pacific.

To block Japanese ambitions, the United States Army had scant resources. Two small forces constituted the heart of the American land defenses in the Pacific--the garrison in the Territory of Hawaii and General Douglas MacArthur's command in the Commonwealth of the Philippines. Both were peacetime organizations, whose days were given to rounds of ceremonies, inspections, and languid training. Officers and their wives occupied evenings and weekends with rounds of social activities and golf, while the soldiers enjoyed more earthy pleasures in the bars and brothels of Honolulu or Manila.

Yet these forces would face overwhelming odds in the event of war. The thousands of islands that comprised the Philippines lay 8,000 miles from the American west coast, but only 200 miles from Japanese-held Formosa. To defend them, General MacArthur had the equivalent of two divisions of regular troops--16,000 U.S. regulars and 12,000 Philippine Scouts. He could call on additional thousands of Philippine militia, but they were untrained and ill equipped. Lt. Gen. Walter C. Short's Hawaiian command held 43,000 Army troops, including two infantry divisions, coast artillery, air corps, and support troops. Thus, in ground forces, the United States had the equivalent of three divisions in the Pacific to stand in the path of the Imperial Japanese Army.

American strategists had developed two plans to counter possible Japanese aggression--one for the Navy and another for the Army. The Navy planned to fight across the central Pacific for a climactic and decisive battle with the Japanese fleet. The Army saw no way to save the Philippines and favored a strategic defense along an Alaska-Hawaii-Panama line. Writing off the Philippines, however, was politically impossible, and as war drew closer frantic efforts were made to strengthen the commonwealth's defenses. Both MacArthur and Army Chief of Staff General George C. Marshall overestimated the chances of their own forces and underestimated the strength and ability of the Japanese. In particular, they grossly exaggerated the power of a new weapon, the B-17 "Flying Fortress" bomber, a few of which were rushed to the Philippines in the last days of peace.

All of the efforts proved to be too little, too late. The Japanese war plan worked to perfection. On 7 December 1941, Japan paralyzed the Pacific Fleet in its attack on Pearl Harbor. In the Philippines, Japanese fliers destroyed most of MacArthur's air force on the ground. Freed of effective opposition, Japanese forces took Burma, Malaya, Singapore, and the Dutch East Indies in rapid succession. By March 1942 the Japanese had conquered an empire. Only MacArthur's beleaguered American-Filipino army still held out on the main Philippine island of Luzon.

A Japanese army had landed in northern Luzon on 22 December 1941 and began to push southward toward Manila. At first, MacArthur was inclined to meet the Japanese on the beaches. But he had no air force, and the U.S. Navy's tiny Asiatic fleet was in no position to challenge Japan at sea. The U.S. regulars and Philippine Scouts were excellent troops but were outnumbered and without air support. Giving up his initial strategy of defeating the enemy on the beaches, MacArthur decided to withdraw to the Bataan Peninsula. There he could pursue a strategy of defense and delay, shortening his lines and using the mountainous, jungle-covered terrain to his advantage. Perhaps he could even hold out long enough for a relief force to be mounted in the United States.

But too many people crowded into Bataan, with too little food and ammunition. By March it was clear that help from the United States was not coming. Nevertheless, the American-Filipino force, wracked by dysentery and malaria, continued to fight. In March President Roosevelt ordered MacArthur to escape to Australia. He left his command to Lt. Gen. Jonathan Wainwright and to Maj. Gen. Edward King, who on 9 April was forced to surrender the exhausted and starving Bataan force. Wainwright continued to resist on the small fortified island of Corregidor in Manila Bay until 6 May under constant Japanese artillery and air bombardment. After Japanese troops stormed ashore on the island, Wainwright agreed to surrender Corregidor and all other troops in the islands. By 9 May 1942, the battle for the Philippines had ended, though many Americans and Filipinos took to the hills and continued a guerrilla war against the Japanese.

The courageous defense of Bataan had a sad and ignominious end. Marching their prisoners toward camps in northern Luzon, the Japanese denied food and water to the sick and starving men. When the weakest prisoners began to straggle, guards shot or bayoneted them and threw the bodies to the side of the road. Japanese guards may have killed 600 Americans and 10,000 Filipino prisoners. News of the Japanese attack on Pearl Harbor had outraged the American people; news of the "Bataan Death March" filled them with bitter hatred.

By May 1942 the Japanese had succeeded beyond their wildest expectations. A vast new empire had fallen into their hands so quickly, and at so little cost, that they were tempted to go further. If their forces could move into the Solomon Islands and the southern coast of New Guinea, they could threaten Australia and cut the American line of communications to MacArthur's base there. If they could occupy Midway Island, only 1,000 miles from Honolulu, they could force the American fleet to pull back to the west coast. In Japanese overconfidence lay the seeds of Japan's first major defeats.

The Tide Turns

Japanese fortunes turned sour in mid-1942. Their uninterrupted string of victories ended with history's first great carrier battles. In May 1942 the Battle of the Coral Sea halted a new Japanese offensive in the south Pacific. A month later the Japanese suffered a devastating defeat at the Battle of Midway in the central Pacific. Now American and Australian forces were able to begin two small counteroffensives--one in the Solomons and the other on New Guinea's Papuan peninsula. The first featured the Marine Corps and the Army; the second, the Army and the Australian Allies.

American resources were indeed slim. When MacArthur arrived in Australia in March 1942, he found, to his dismay, that he had little to command. Australian militia and a few thousand U.S. airmen and service troops were his only resources. The Australian 7th Division soon returned from North Africa, where it had been fighting the Germans, and two U.S. National Guard divisions, the 32d and the 41st, arrived in April and May. MacArthur had enough planes for two bomber squadrons and six fighter squadrons. With only these forces, he set out to take Papua, while Admiral Nimitz, with forces almost equally slim, attacked Guadalcanal in the Solomon Islands.

Of all the places where GIs fought in the Second World War, Guadalcanal and the Papuan peninsula may have been the worst. Though separated by 800 miles of ocean, the two were similarly unhealthful in terrain and climate. The weather on both is perpetually hot and wet; rainfall may exceed 200 inches a year, and during the rainy season deluges, sometimes 8 to 10 inches of rain, occur daily. Temperatures in December reach the high eighties, and humidity seldom falls below 80 percent. Terrain and vegetation are equally foreboding--dark, humid,

jungle-covered mountains inland, and evil-smelling swamps along the coasts. Insects abound. The soldiers and marines were never dry; most fought battles while wracked by chills and fever. For every two soldiers lost in battle, five were lost to disease--especially malaria, dengue, dysentery, or scrub typhus, a dangerous illness carried by jungle mites. Almost all suffered "jungle rot," ulcers caused by skin disease.

Guadalcanal lay at the southeast end of the Solomons, an island chain 600 miles long. Navy carriers and other warships supported the landings, but they could not provide clear air or naval superiority. The marines landed on 7 August 1942, without opposition, and quickly overran an important airfield. That was the last easy action on Guadalcanal. The carriers sailed away almost as soon as the marines went ashore. Then Japanese warships surprised the supporting U.S. naval vessels at the Battle of Savo Island and quickly sank four heavy cruisers and one destroyer. Ashore, the Japanese Army fought furiously to regain the airfield. Through months of fighting the marines barely held on; some American admirals even thought that the beachhead would be lost. But gradually land-based aircraft were ferried in to provide air cover, and the Navy was able to return. As the Japanese continued to pour men into the fight, Guadalcanal became a battle of attrition.

Slowly American resources grew, while the Japanese were increasingly unable to make up their losses. In October soldiers of the Americal Division joined the battle; in November the Navy won a smashing victory in the waters offshore; and in early 1943 the Army's 25th Infantry Division was committed as well. Soldiers now outnumbered marines, and the ground forces were reorganized as the XIV Corps, commanded by Army Mail Gen. Alexander M. Patch. As the Japanese lost the ability to supply their forces, enemy soldiers began to starve in the jungles. But not until February--six months after the initial landing--was Guadalcanal finally secured.

Meanwhile, 800 miles to the west on the eastern peninsula of New Guinea, another shoestring offensive began. Even after the Battle of the Coral Sea, the Japanese persisted in their efforts to take Port Moresby, a strategic town on New Guinea's southern coast. In late July 1942 they landed on the north coast of the huge, mountainous island and began to make their way south toward Port Moresby, across the towering Owen Stanley Mountains. Almost impassable in normal circumstances, the trail they followed was a quagmire under constant rain. Supply became impossible;
