1942 Battle of Midway begins

On this day in 1942, the Battle of Midway–one of the most decisive U.S. victories against Japan during World War II–begins. During the four-day sea-and-air battle, the outnumbered U.S. Pacific Fleet succeeded in destroying four Japanese aircraft carriers while losing only one of its own, the Yorktown, to the previously invincible Japanese navy.
In six months of offensives prior to Midway, the Japanese had triumphed in lands throughout the Pacific, including Malaysia, Singapore, the Dutch East Indies, the Philippines and numerous island groups. The United States, however, was a growing threat, and Japanese Admiral Isoruku Yamamoto sought to destroy the U.S. Pacific Fleet before it was large enough to outmatch his own.
A thousand miles northwest of Honolulu, the strategic island of Midway became the focus of his scheme to smash U.S. resistance to Japan’s imperial designs. Yamamoto’s plan consisted of a feint toward Alaska followed by an invasion of Midway by a Japanese strike force. When the U.S. Pacific Fleet arrived at Midway to respond to the invasion, it would be destroyed by the superior Japanese fleet waiting unseen to the west. If successful, the plan would eliminate the U.S. Pacific Fleet and provide a forward outpost from which the Japanese could eliminate any future American threat in the Central Pacific. U.S. intelligence broke the Japanese naval code, however, and the Americans anticipated the surprise attack.
In the meantime, 200 miles to the northeast, two U.S. attack fleets caught the Japanese force entirely by surprise and destroyed three heavy Japanese carriers and one heavy cruiser. The only Japanese carrier that initially escaped destruction, the Hiryu, loosed all its aircraft against the American task force and managed to seriously damage the U.S. carrier Yorktown, forcing its abandonment. At about 5:00 p.m., dive-bombers from the U.S. carrier Enterprise returned the favor, mortally damaging the Hiryu. It was scuttled the next morning.
When the Battle of Midway ended, Japan had lost four carriers, a cruiser and 292 aircraft, and suffered an estimated 2,500 casualties. The U.S. lost the Yorktown, the destroyer USS Hammann, 145 aircraft and suffered approximately 300 casualties.
Japan’s losses hobbled its naval might–bringing Japanese and American sea power to approximate parity–and marked the turning point in the Pacific theater of World War II. In August 1942, the great U.S. counteroffensive began at Guadalcanal and did not cease until Japan’s surrender three years later.
