This Week in American History: August 9 through August 15
The period between August 9 and August 15 in American history featured the development of the atomic bomb with the institution of the “Manhattan Project” in 1942, the second dropping of the atomic bomb in 1945 - this time in Nagasaki, Japan and the subsequent unconditional surrender of Imperial Japan to the Allied Forces.
August 9, 1945: Days after the bombing of Hiroshima, Imperial Japan refused to surrender. The U.S. dropped another atomic bomb via B-29 bomber on Nagasaki, killing tens of thousands. The very next day (August 10), Imperial Japan accepted the terms of surrender. The official surrender date was September 2, 1945.
