Why was US President Truman "on the high seas" when the Hiroshima atomic bomb was dropped?
From the New York Times, August 7 1945. [First Atomic Bomb Dropped on Japan; Missile Is Equal to 20,000 Tons of TNT; Truman Warns Foe of a 'Rain of Ruin'](http://www.nytimes.com/learning/general/onthisday/big/0806.html) > The first news came from President Truman's office. Newsmen were > summoned and the historic statement from the Chief Executive, who still > is on the high seas, was given to them. Why was he on the high seas at this moment? Was he on an important trip or a mission?
