What was Isoroku Yamamoto's role in "the most stunning and decisive blow in the history of naval warfare."?
Battle of Midway The Battle of Midway was a decisive naval battle in the Pacific Theater of World War II which occurred between 4 and 7 June 1942, only six months after Japan's attack on Pearl Harbor and one month after the Battle of the Coral Sea. The United States Navy under Admirals Chester Nimitz, Frank Jack Fletcher, and Raymond A. Spruance defeated an attacking fleet of the Imperial Japanese Navy under Admirals Isoroku Yamamoto, Chuichi Nagumo, and Nobutake Kondo near Midway Atoll, inflicting devastating damage on the Japanese fleet that proved irreparable. Military historian John Keegan called it "the most stunning and decisive blow in the history of naval warfare."
Type 93 torpedo The Type 93 (九三式魚雷 , designated for Imperial Japanese calendar year 2593) was a 61 cm -diameter torpedo of the Imperial Japanese Navy (IJN), launched from surface ships. It is commonly referred to as the Long Lance by most modern English-language naval historians, a nickname given it after the war by Samuel Eliot Morison, the chief historian of the U.S. Navy, who spent much of the war in the Pacific Theater. In Japanese references, the term "Sanso gyorai" (酸素魚雷 , lit. "oxygen torpedo") is also used, in reference to its propulsion system. It was the most advanced naval torpedo in the world at the time.
