Fleet Admiral William Frederick Halsey, Jr., GBE, USN, (1882–1959) (called "Bill Halsey" and sometimes known as "Bull" Halsey), was a United States Navy officer and the commander of the United States Third Fleet against Japan during World War II.
Vice-Admiral William Halsey (1882-1941) was aboard his flagship USS Enterprise on December 7, 1941, when Japan began its invasion of the American territory of Hawaii by attacking Pearl Harbor. The Enterprise and the rest of the fleet rushed to engage the Japanese navy but were surprised by several squadrons of Japanese Zeros. The Enterprise was heavily damaged by the Japanese planes. Halsey died in the attack.
William Halsey was a commodore in the U.S. Navy during the Second Great War. He commanded Naval forces in the Chesapeake Bay.
In 1942, he agreed to transport Daniel MacArthur's army to the Virginia Peninsula -without informing the General Staff. The landing was called off when MacArthur's subordinate General Abner Dowling informed the General Staff of the plan against MacArthur's wishes and without his knowledge.
