Two independent, coordinate commands, one in the Southwest Pacific under General of the Army Douglas MacArthur and the other in the Central, South, and North Pacific (Pacific Ocean Areas) under Fleet Admiral Chester W. Nimitz, were created early in the war. Except in the South and Southwest Pacific, each conducted its own operations with its own ground, air, and naval forces in widely separated areas. These operations required at first only a relatively small number of troops whose efforts often yielded strategic gains which cannot be measured by the size of the forces involved. Indeed, the nature of the objectivesùsmall islands, coral atolls, and jungle-bound harbors and airstrips, made the employment of large ground forces impossible and highlighted the importance of air and naval operations. Thus, until 1945, the war in the Pacific progressed by a double series of amphibious operations each of which fitted into a strategic pattern developed in Washington.... More

The United States offensive, under the overall command of Chester Nimitz, followed the Gilbert and Marshall Islands campaign and was intended to neutralize Japanese bases in the central Pacific, support the Allied drive to retake the Philippines, and provide bases for a strategic bombing campaign against Japan.
Beginning the offensive, United States Marine Corps and United States Army forces, with support from the United States Navy, executed landings on Saipan in June, 1944. In response, the Imperial Japanese Navy's combined fleet sortied to attack the U.S. Navy fleet supporting the landings. In the resulting aircraft carrier Battle of the Philippine Sea (the so-called “Great Marianas Turkey Shoot”) on 19–20 June, the Japanese naval forces were decisively defeated with heavy and irreplaceable losses to their carrier-borne and land-based aircraft.
Thereafter, U.S. forces executed landings on Guam and Tinian in July, 1944. After heavy fighting, Saipan was secured in July and Guam and Tinian in August, 1944. The U.S. then constructed airfields on Saipan and Tinian where B-29s were based to conduct strategic bombing missions against the Japanese mainland until the end of World War II, including the nuclear attacks on Hiroshima and Nagasaki.
In the meantime, in order to secure the flank for U.S. forces preparing to attack Japanese forces in the Philippines, in September, 1944, U.S. Marine and Army forces landed on the islands of Peleliu and Angaur in Palau. After heavy and intense combat on Peleliu, the island was finally secured by U.S. forces in November, 1944.
Following their landings in the Mariana and Palau Islands, Allied forces continued their ultimately successful campaign against Japan by landing in the Philippines in October, 1944 and the Volcano and Ryukyu Islands beginning in January, 1945.... More
Description The Battle of Leyte Gulf, also called the Battles for Leyte Gulf, and formerly known as the Second Battle of the Philippine Sea, is generally considered to be the largest naval battle of World War II The Battle of Leyte Gulf, also called the Battles for Leyte Gulf, and formerly known as the Second Battle of the Philippine Sea, is generally considered to be the largest naval battle of World War II and, by some criteria, possibly the largest naval battle in history.
It was fought in waters near the Philippine islands of Leyte, Samar and Luzon from 23–26 October 1944, between combined US and Australian forces and the Imperial Japanese Navy. On 20 October, United States troops invaded the island of Leyte as part of a strategy aimed at isolating Japan from the countries it had occupied in Southeast Asia, and in particular depriving its forces and industry of vital oil supplies. The Imperial Japanese Navy (IJN) mobilized nearly all of its remaining major naval vessels in an attempt to defeat the Allied invasion, but was repulsed by the US Navy's 3rd and 7th Fleets. The IJN failed to achieve its objective, suffered very heavy losses, and never afterwards sailed to battle in comparable force. The majority of its surviving heavy ships, deprived of fuel, remained in their bases for the rest of the Pacific War.
The Battle of Leyte Gulf consisted of four separate engagements between the opposing forces: the Battle of the Sibuyan Sea, the Battle of Surigao Strait, the Battle of Cape Engaño and the Battle off Samar, as well as other actions.
It was the first battle in which Japanese aircraft carried out organized kamikaze attacks. By the time of the battle, Japan had fewer aircraft than the Allied forces had sea vessels, demonstrating the difference in power of the two sides at this point of the war. ... More

The battle was the first action in which aircraft carriers engaged each other, as well as the first in which neither side's ships sighted or fired directly upon the other.
In an attempt to strengthen their defensive positioning for their empire in the South Pacific, Japanese forces decided to invade and occupy Port Moresby in New Guinea and Tulagi in the southeastern Solomon Islands. The plan to accomplish this, called Operation MO, involved several major units of Japan's Combined Fleet, including two fleet carriers and a light carrier to provide air cover for the invasion fleets, under the overall command of Japanese Admiral Shigeyoshi Inoue. The US learned of the Japanese plan through signals intelligence and sent two United States Navy carrier task forces and a joint Australian-American cruiser force, under the overall command of American Admiral Frank J. Fletcher, to oppose the Japanese offensive.
On 3–4 May, Japanese forces successfully invaded and occupied Tulagi, although several of their supporting warships were surprised and sunk or damaged by aircraft from the US fleet carrier Yorktown. Now aware of the presence of US carriers in the area, the Japanese fleet carriers entered the Coral Sea with the intention of finding and destroying the Allied naval forces.
Beginning on 7 May, the carrier forces from the two sides exchanged airstrikes over two consecutive days. The first day, the US sank the Japanese light carrier Shoho, while the Japanese sank a US destroyer and heavily damaged a fleet oiler (which was later scuttled). The next day, the Japanese fleet carrier Shokaku was heavily damaged, the US fleet carrier Lexington was critically damaged (and was scuttled as a result), and the Yorktown was damaged. With both sides having suffered heavy losses in aircraft and carriers damaged or sunk, the two fleets disengaged and retired from the battle area. Because of the loss of carrier air cover, Inoue recalled the Port Moresby invasion fleet, intending to try again later.
Although a tactical victory for the Japanese in terms of ships sunk, the battle would prove to be a strategic victory for the Allies for several reasons. The battle marked the first time since the start of the war that a major Japanese advance had been checked by the Allies. More importantly, the Japanese fleet carriers Sokaku and Zuikaku – one damaged and the other with a depleted aircraft complement – were unable to participate in the Battle of Midway, which took place the following month, ensuring a rough parity in aircraft between the two adversaries and contributing significantly to the US victory in that battle. The severe losses in carriers at Midway prevented the Japanese from reattempting to invade Port Moresby from the ocean. Two months later, the Allies took advantage of Japan's resulting strategic vulnerability in the South Pacific and launched the Guadalcanal Campaign that, along with the New Guinea Campaign, eventually broke Japanese defenses in the South Pacific and was a significant contributing factor to Japan's ultimate defeat in World War II....

Description The Battle of Midway in the Pacific Theater of Operations was one of the most important naval battles of World War II. Between 4 and 7 June 1942, only six months after Japan's attack on Pearl Harbor, The Battle of Midway in the Pacific Theater of Operations was one of the most important naval battles of World War II. Between 4 and 7 June 1942, only six months after Japan's attack on Pearl Harbor, and one month after the Battle of the Coral Sea, the United States Navy (USN), under Admirals Chester W. Nimitz, Frank Jack Fletcher, and Raymond A. Spruance decisively defeated an attack by the Imperial Japanese Navy (IJN), under Admirals Isoroku Yamamoto, Chuichi Nagumo, and Nobutake Kondo on Midway Atoll, inflicting irreparable damage on the Japanese fleet. Military historian John Keegan called it "the most stunning and decisive blow in the history of naval warfare." It was Japan's first naval defeat since the Battle of Shimonoseki Straits in 1863.
The Japanese operation, like the earlier attack on Pearl Harbor, sought to eliminate the United States as a strategic power in the Pacific, thereby giving Japan a free hand in establishing its Greater East Asia Co-Prosperity Sphere. The Japanese hoped that another demoralizing defeat would force the U.S. to capitulate in the Pacific War and thus ensure Japanese dominance in the Pacific.
The Japanese plan was to lure the United States' aircraft carriers into a trap. The Japanese also intended to occupy Midway as part of an overall plan to extend their defensive perimeter in response to the Doolittle air raid on Tokyo. This operation was also considered preparatory for further attacks against Fiji, Samoa, and Hawaii itself.
The plan was handicapped by faulty Japanese assumptions of the American reaction and poor initial dispositions.Most significantly, American codebreakers were able to determine the date and location of the attack, enabling the forewarned U.S. Navy to set up an ambush of its own. Four Japanese aircraft carriers—Akagi, Kaga, Soryu and Hiryu, all part of the six-carrier force that had attacked Pearl Harbor six months earlier—and a heavy cruiser were sunk at a cost of one American aircraft carrier and a destroyer. After Midway and the exhausting attrition of the Solomon Islands campaign, Japan's shipbuilding and pilot training programs were unable to keep pace in replacing their losses, while the U.S. steadily increased its output in both areas....
