The United States was caught unprepared for a surprise Japanese air attack on December 7, 1941 and suffered its worst naval defeat in history.  With successive invasions and defeats in Guam and the Philippines, including the surrender of its remaining army at Corregidor, the United States was losing the war in the Pacificto Japan in June, 1942.  Yet there remained a flicker of hope, because the American aircraft carriers had not been caught at Pearl Harbor and could still roam the seas, threatening the Japanese home islands and further conquests abroad.  Japanese supreme commander Yamamoto was determined to ambush the four American carriers and end the threat once and for all.  Newly appointed Pacific Fleet commander Chester Nimitz took over a demoralized fleet at Pearl Harbor knowing he could not allow the loss of his carriers or his island base in Hawaii.  When he learned of an impending attack on Midway Island, he risked everything in a desperate gamble to outfox the Japanese fleet and ambush their carriers.  This is the story of a miraculous and pivotal victory at sea that ranks with the greatest in history.
