The Target Committee at Los Alamos on May 10ป, 1945, recommended Kyoto, Hiroshima, Yokohama and the arsenal at Kokura as possible targets. The committee rejected the use of the weapon against a strictly military objective due to the chance of missing a small target not surrounded by a larger urban area. The psychological effects on Japan were of great importance to the committee members. They also agreed that the initial use of the weapon should be sufficiently spectacular for its importance to be internationally recognized. The committee felt Kyoto, as an intellectual center of Japan, had a population "better able to appreciate the significance of the weapon." Hiroshima was chosen due to its large size, its being "an important army depot" and the potential that the bomb would cause greater destruction due to its being surrounded by hills which would have a "focusing effect". Secretary of War Henry L. Stimson struck Kyoto from the list because of its cultural significance, over the objections of Gen. Leslie Groves, head of the Manhattan Project. According to Professor Edwin O. Reischauer, Stimson "had known and admired Kyoto ever since his honeymoon there several decades earlier." On July 25 General Carl Spaatz was ordered to bomb one of the targets: Hiroshima, Kokura, Niigata or Nagasaki as soon after August 3 as weather permitted, and the remaining cities as additional weapons became available. At the time of its bombing, Hiroshima was a city of considerable industrial and military significance. Even some military camps were located nearby, such as the headquarters of the Fifth Division and Field Marshal Shunroku Hata's 2nd General Army Headquarters, which commanded the defense of all of southern Japan. Hiroshima was a minor supply and logistics base for the Japanese military. The city was a communications center, a storage point, and an assembly area for troops. It was one of several Japanese cities left deliberately untouched by American bombing, allowing an ideal environment to measure the damage caused by the atomic bomb. Another account stresses that after General Spaatz reported that Hiroshima was the only targeted city without POW-camps, Washington decided to assign it highest priority. The center of the city contained a number of reinforced concrete buildings and lighter structures. Outside the center, the area was congested by a dense collection of small wooden workshops set among Japanese houses. A few larger industrial plants lay near the outskirts of the city. The houses were of wooden construction with tile roofs, and many of the industrial buildings also were of wood frame construction. The city as a whole was highly susceptible to fire damage. The population of Hiroshima had reached a peak of over 381,000 earlier in the war, but prior to the atomic bombing the population had steadily decreased because of a systematic evacuation ordered by the Japanese government. At the time of the attack the population was approximately 255,000. This figure is based on the registered population used by the Japanese in computing ration quantities, and the estimates of additional workers and troops who were brought into the city may be inaccurate. Hiroshima was the primary target of the first U.S. nuclear attack mission, on August 6, 1945. The B-29 Enola Gay, piloted and commanded by Colonel Paul Tibbets, was launched from Tinian airbase in the West Pacific, approximately 6 hours' flight time away from Japan. The drop date of the 6th was chosen because there had previously been a cloud formation over the target. At the time of launch, the weather was good, and the crew and equipment functioned properly. Navy Captain William Parsons armed the bomb during the flight, since it had been left unarmed to minimize the risks during takeoff. In every detail, the attack was carried out exactly as planned, and the gravity bomb, a gun-type fission weapon, with 60 kg (130 pounds) of uranium-235, performed precisely as expected. About an hour before the bombing, the Japanese early warning radar net detected the approach of some American aircraft headed for the southern part of Japan. The alert had been given and radio broadcasting stopped in many cities, among them Hiroshima. The planes approached the coast at a very high altitude. At nearly 08:00, the radar operator in Hiroshima determined that the number of planes coming in was very small$probably not more than three$and the air raid alert was lifted. (To save gasoline, the Japanese had decided not to intercept small formations, which were assumed to be weather planes.) The three planes present were the Enola Gay (named after Colonel Tibbets' mother), The Great Artiste (a recording and surveying craft), and a then-nameless plane later called Necessary Evil (the photographing plane). The normal radio broadcast warning was given to the people that it might be advisable to go to air-raid shelters if B-29s were actually sighted, but no raid was expected beyond some sort of reconnaissance. At 08:15, the Enola Gay dropped the nuclear bomb called "Little Boy" over the center of Hiroshima. It exploded about 600 meters (2,000 feet) above the city with a blast equivalent to 13 kilotons of TNT, killing an estimated 70,000๠,000 people. At least 11 U.S. POWs also died. Infrastructure damage was estimated at 90% of Hiroshima's buildings being either damaged or completely destroyed.
