At the turn of the century the Japanese naval college had moved to the island of Etajima, off Hiroshima. Nagumo's unfamiliarity with naval aviation showed itself, however, when he opposed the launching of further raids, which could have destroyed millions of gallons of fuel stored at Pearl Harbor, Nagumo later summarized his reasons for the withdrawal by stating, "1. The first attack had inflicted all the damage we had hoped for. Once again Nagumo opposed Yamamoto's plan, but was placed in command of the operation nonetheless. With nearly all of Saipan in U.S. hands and no escape possible, Nagumo committed suicide on the night of July 6, 1944.Nagumo's fleet, comprising three battleships, six large aircraft carriers, and numerous smaller vessels, left Japanese waters to attack Hawaii in late November 1941. This incomplete victory did not allow the Japanese to adequately reinforce their troops on Guadalcanal, and they evacuated the island in February 1943.Nagumo remained on Saipan and assisted in the island's defense against the U.S. invasion, which commenced on June 15, 1944. In the ensuing battle, the Japanese lost their small aircraft carrier while heavily damaging one of the American fleet carriers. By the late 1920s, Britain and the United States were becoming concerned about the growth of Japanese naval strength and convened the first London Conference in 1930, in an effort to avoid a naval arms race in the Pacific. Enemy fire had been surprisingly prompt even though we took them by surprise. They were assisted by European navies eager to sell their equipment and expertise. Nagumo was born in the city of Yonezawa, Yamagata Prefecture in northern Japan in 1887. Yamamoto called off the Midway operation, with Nagumo's agreement, in the early morning hours of June 5.
On Japanese carriers in 1942, the process of moving fully armed strike bombers from hangar to flight deck and preparing them for take-off normally required a minimum of forty minutes. During that time, many of his first attack wave aircraft would run out of fuel and have to ditch in the sea. Vice Admiral Nagumo faces his first problem.
The flight decks had to be kept clear of strike bombers in order to allow the combat air patrol Zeros to be recovered, refuelled, rearmed, and relaunched to defend their carriers.Another alternative was to hold the Japanese bombers on their carriers in readiness to repel a possible American naval counter-attack, and await the return of the first attack wave. The Russian and Japanese fleets met in the Straits of Tsushima on May 27, 1904, and the new Japanese navy annihilated the Russians in one of the most decisive naval battles in history.Japan further distanced itself from Britain and the United States by signing the Tripartite Pact with fascist powers, Germany and Italy on September 27, 1940.
