The Battle of Leyte Gulf marked the last time the Imperial Japanese Navy would conduct large-scale operations during the war. Humiliated by that setback, the Japanese navy continued to bomb Wake Island and eventually sent a much larger task force of approximately 2,000 SNLF troops to take the atoll. Army troops were also involved in this campaign, though not at first.The 2nd Battalion of Marine Raiders made a raid on Makin Atoll in the Gilbert Islands later that month, but this was not intended to be a permanent occupation. American commanders decided to make the first Mariana landing on Saipan, the largest of the Mariana Islands. The Japanese garrison commander, Capt.

The survivors became prisoners of war, and most were evacuated to China and Japan, although 98 civilian workers were kept on the island to be used as forced labour. The land-based air forces operations in China not only gave it valuable experience but also prompted a rapid increase of its strength: the Zero fighter made its debut there, as did Japans twin-engined bomber. For the Southern Operation, two drivesone from Formosa through the Philippines, the other from French Indochina and Hainan Island through Malayawere to converge on the Dutch East Indies.

On the night of the 24th, part of the Southern Force led by Vice Admiral Shoji Nishimura entered the Surigao Straight where they were attacked by 28 Allied destroyers and 39 PT boats. Subsequently, Marines headed straight into exploding bombs and streaming gunfire. Beginning at dawn, it lasted over fifteen hours and overran two American battalions before it was contained and defeated. The key elements of Cartwheel involved Allied forces under General Douglas MacArthur pushing across northeastern New Guinea, while naval forces secured the Solomon Islands to the east. U.S. forces had refined their amphibious strategy over a year of hard fighting, and by this time had it down to a science: Massive naval bombardment of land-based targets preceded troop landings, which were supported by strafing and bombing runs by carrier-based aircraft. After overcoming these difficulties, the Marines were able to push inland, though the advance was slow. No one thought of canceling the Peleliu landings though.Iwo Jima, like Tarawa, was an all-Marine operation, lasting for six weeks beginning in mid February 1945. Nature was the greatest enemy here - more Marines were killed by falling trees in the rain-soaked jungle than by the enemy.

With Okinawa secured and American bombers regularly bombing and firebombing Japanese cities, planning moved forward for the invasion of Japan. The target date was set at 150 days after the start of the war. By the end of the day, all four of Ozawa's carriers had been sunk. That small engagement, the first tactical defeat experienced by the Japanese navy in World War II, electrified the American people, dispelling much of the gloom caused by Pearl Harbor. As the island-hopping campaign began, MacArthur continued his push in New Guinea while other Allied troops were engaged in clearing the Japanese from the Aleutians. These would then be used as bases for attacking the Japanese home islands. Geography.

Kinkaid was not aware of this as he believed Halsey had left one carrier group to cover the San Bernardino Straight. As the Americans advanced, the island's civilians, who had been convinced that the Allies were barbarians, began a mass suicide, jumping from the island's cliffs. Though the controversial attack on Peleliu resulted in a higher death toll than any other amphibious assault in U.S. military history, Allied commanders and troops learned important lessons that would benefit them during the invasion of the Philippines and the Japanese home islands. The Japanese used Peleliu's unique terrain to their advantage, stationing troops in caves just above invading U.S. forces so as to inflict the maximum amount of damage on the troops below. In the battle, the escort carrierUSSPrinceton(CVL-23) was sunk by land-based bombers. On September 15, 1944, U.S. Marines fighting in World War II (1939-45) landed on Peleliu, one of the Palau Islands of the western Pacific. It was for this strategic reason that the Japanese Navy had made strenuous efforts to build up its auxiliary strength while its battleships were limited to 60 percent of the U.S. strength by the Washington Naval Treaty of 1922 and that Japan in 1934 gave notice of withdrawal from that treaty as from 1936. Rather than engage sizable Japanese garrisons, these operations were designed to cut them off and let them "wither on the vine." The prospect was scarcely bright.

Spruance's Task Force 58 launched the first of many pre-invasion air sorties on June 11 on Japanese positions, airplanes, and ships. The next objective for Admiral Chester Nimitzs Pacific Fleet was the Palau Islands in the western Carolines, 500 miles east of the Philippines. The atolls defenders had received word of the Pearl Harbor attack several hours earlier (Wake and Hawaii are separated by the International Date Line), but heavy cloud cover and the absence of radar facilities allowed the attackers to achieve surprise. While the Japanese naval threat was removed, an aerial one remained: kamikazes. With two other ships damaged in collisions while trying to avoid American torpedoes, the scattered Japanese chose to retreat. With the Gilberts and Marshalls secure, U.S. commanders began planning for the invasion of the Marianas. Official U.S. Navy Photograph, now in the collections of the National Archives. While Ozawa did launch a strike of around 75 aircraft against Halsey, this force was largely destroyed and inflicted no damage. Although the Battle of Wake Island ended in a U.S. defeat, the Japanese navy suffered significant losses at the hands of a much smaller American force. The Mariana Islands were the last bastion of Japan's Central Pacific perimeter. They lost four ships, one submarine, and some 1,000 lives; just over 100 Americans and Guamanians died during their defense of Wake Island. MacArthur and Admiral Chester Nimitz followed Halseys advice about Leyte, but chose to go ahead with the attack on Peleliu. Battleships, destroyers and planes had pounded key targets in pre-assault bombardments, but they had missed many gun emplacements along the beach cliffs. Admiral Chester Nimitzadvocated bypassing the Philippines in favor of capturing Formosa and Okinawa. Against determined resistance from the enemy, the 2d Marine Division on the left flank and the 4th Marine Division on the right flank seized their objectives; however, the Army's attack in the center faltered. In the spring of 1944, U.S. forces involved in the Pacific Campaign invaded Japanese-held islands in the central Pacific Ocean along a path toward Japan. Located about 2,000 miles (3,200 km) west of Hawaii and 600 miles (approximately 1,000 km) north of the Japanese-held Marshall Islands, Wake Island impressed American naval planners as an ideal site for an advance defensive outpost. Soon to be designated Death Valley, the area was bordered by a ridge where well-protected, heavily armed Japanese soldiers fired directly down on the approaching Americans.

On June 15, 1944, during the Pacific Campaign of World War II (1939-45), U.S. Marines stormed the beaches of the strategically significant Japanese island of Saipan, with a goal of gaining a crucial air base from which the U.S. could launch its new long-range B-29 bombers directly at Japans home islands. These methods had worked in earlier landings and were expected to work again on Peleliu. Sakaibara Shigematsu, interpreted one such attack, in October 1943, as an invasion attempt, prompting him to order the execution of the remaining civilians on the island. When the Marines turned north to begin their advance, they were targeted along the way by heavy artillery fire and a fusillade of small arms from Japanese forces installed in caves dug into the rocky surface of Umurbrogol Mountain, which the Marines dubbed Bloody Nose Ridge. Over the next eight days, U.S. troops sustained about 50 percent casualties in some of the most vicious and costly fighting of the Pacific campaign. This was accomplished after heavy fighting around Yae-Take. U.S. commanders reasoned that taking the main Mariana IslandsSaipan, Tinian and Guamwould cut off Japan from its resource-rich southern empire and clear the way for further advances to Tokyo. Over the next several weeks, ferocious Japanese resistance inflicted heavy casualties on U.S. troops before the Americans were finally able to secure the island.
