Harry S. Truman, Diary, July 25, 1945
President Truman told his diary on July 25, 1945, that he had ordered the bomb used. Emphasis has been added to highlight Truman's apparent belief that he had ordered the bomb dropped on a "purely military" target, so that "military objectives and soldiers and sailors are the target and not women and children."
We have discovered the most terrible bomb in the history of the world. It may be the fire destruction prophesied in the Euphrates Valley Era, after Noah and his fabulous Ark.
Anyway we "think" we have found the way to cause a disintegration of the atom. An experiment in the New Mexico desert was startling - to put it mildly. Thirteen pounds of the explosive caused the complete disintegration of a steel tower 60 feet high, created a crater 6 feet deep and 1,200 feet in diameter, knocked over a steel tower 1/2 mile away and knocked men down 10,000 yards away. The explosion was visible for more than 200 miles and audible for 40 miles and more.
This weapon is to be used against Japan between now and August 10th. I have told the Sec. of War, Mr. Stimson, to use it so that military objectives and soldiers and sailors are the target and not women and children. Even if the Japs are savages, ruthless, merciless and fanatic, we as the leader of the world for the common welfare cannot drop that terrible bomb on the old capital or the new.
He and I are in accord. The target will be a purely military one and we will issue a warning statement asking the Japs to surrender and save lives. I'm sure they will not do that, but we will have given them the chance. It is certainly a good thing for the world that Hitler's crowd or Stalin's did not discover this atomic bomb. It seems to be the most terrible thing ever discovered, but it can be made the most useful...
Truman quoted in Robert H. Ferrell, Off the Record: The Private Papers of Harry S. Truman (New York: Harper and Row, 1980) pp. 55-56. Truman's writings are in the public domain.
This source supports our thesis because it says that the President did not want any civillians to be killed. The bomb was to be used strictly on military bases. Most people involved with the bomb thought that its use would lead to a quicker end to the war. Because the bomb was so powerful it was thought that Japan would be in awe of America and want to surrender.
Truman Speech, August 9, 1945 (excerpt)
In a radio speech to the nation on August 9, 1945, President Truman called Hiroshima "a military base." It seems likely, considering his July 25 diary entry, that he was not aware that Hiroshima was a city. Otherwise, he was being untruthful about the nature of the target.
Truman delivered his speech from the White House at 10 P.M. Washington time on August 9, 1945. By this time, a second atomic bomb already had destroyed the city of Nagasaki. Because of the great length of the speech, most of which dealt with Germany, only the relevant paragraph is quoted here.
The world will note that the first atomic bomb was dropped on Hiroshima, a military base. That was because we wished in this first attack to avoid, insofar as possible, the killing of civilians. But that attack is only a warning of things to come. If Japan does not surrender, bombs will have to be dropped on her war industries and, unfortunately, thousands of civilian lives will be lost. I urge Japanese civilians to leave industrial cities immediately, and save themselves from destruction.

This document shows that President Truman had no intentions of killing civillians. He thought that it would force Japan to surrender. Truman even warned civillians to leave industrialized cities so that they would not be harmed. The use of the first bomb was to scare the Japenese people, and if it didn't do its job then more bombs would be used.
