The atomic bombings of Hiroshima and Nagasaki were nuclear wars during World War II against the Empire of Japan by the United States of America under US President Harry S. Truman. After six months of intense Strategic bombing during World War II#United States strategic bombing of Japan, on August 6, 1945, the nuclear weapon "Little Boy" was dropped on the city of Hiroshima, followed on August 9, 1945 by the detonation of the "Fat Man" nuclear bomb over Nagasaki. These are the only uses of nuclear weapons in warfare.

As many as 140,000 people in Hiroshima and 80,000 in Nagasaki may have died from the bombings by the end of 1945{{cite web|url = http://www.rerf.or.jp/general/qa_e/qa1.html |title = Frequently Asked Questions #1 |publisher= [Radiation Effects Research Foundation | accessdate = 2007-09-18 -->, roughly half on the days of the bombings.Since then, thousands more have died from injuries or illness Radiation poisoning.{{cite web| url = http://www.cfo.doe.gov/me70/manhattan/hiroshima.htm | title = THE ATOMIC BOMBING OF HIROSHIMA | first= David |last= Rezelman |coauthors= F.G.

On August 15, 1945 Japan Surrender of Japan, signing the Japanese Instrument of Surrender on September 2 which officially ended World War II. Furthermore, the experience of bombing led post-war Japan to adopt Three Non-Nuclear Principles, which forbid Japan from nuclear armament.

The Manhattan Project The United States, with assistance from the Tube Alloys and Chalk River Laboratories, designed and built the first atomic bombs under what was called the Manhattan Project. "The gadget," which was a trial of the implosion trigged plutonium device, which would be used on Nagasaki, was detonated during a test called Trinity test near Alamogordo, New Mexico on July 16, 1945. Together the following bombs were the second and third to be detonated and as of 2007 the only ones ever in a military action. (See Weapons of Mass Destruction.)

Choice of targets The Target Committee at Los Alamos National Laboratory on May 10–11, 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 because of 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 because of its large size, its being "an important army depot" and the potential that the bomb would cause greater destruction because the city was 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 General 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, Niigata, or Nagasaki as soon after August 3 as weather permitted and the remaining cities as additional weapons became available.

The Potsdam ultimatum On July 26, Truman and other allied leaders issued The Potsdam Declaration outlining terms of surrender for Japan. The atomic bomb was not mentioned in the declaration. On July 28, Japanese papers reported that the declaration had been rejected by the Japanese government. That afternoon, Prime Minister Kantaro Suzuki declared at a press conference that the Potsdam Declaration was no more than a rehash (yakinaoshi) of the Cairo Declaration and that the government intended to ignore it (mokusatsu).{{cite book], who was waiting for a Soviet reply to noncommittal Japanese peace feelers, made no move to change the government position.{{cite book| first = Herbert | last = Bix | authorlink = Herbert Bix| chapter=Japan's Delayed Surrender: A Reinterpretation| title=Hiroshima in History and Memory| editor=Michael J.

In early July, on his way to Potsdam, Truman had re-examined the decision to use the bomb. In the end, Truman made the decision to drop the atomic bombs on Japan. His stated intention in ordering the bombings was to bring about a quick resolution of the war by inflicting destruction, and instilling fear of further destruction, that was sufficient to cause Japan to surrender.

Hiroshima Hiroshima during World War II At the time of its bombing, Hiroshima was a city of some industrial and military significance. A number of military camps were located nearby, including the headquarters of the Fifth Division and Field Marshal Hata Shunroku'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 prisoner of war (POW) camps, Washington decided to assign it highest priority.

The center of the city contained several 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.

The bombing For the composition of the USAAF mission see 509th Operations Group#Mission compositions. Hiroshima was the primary target of the first nuclear bombing mission on August 6, with Kokura and Nagasaki being alternative targets. August 6 was chosen because there had previously been cloud over the target. The B-29 Superfortress Enola Gay, piloted and commanded by 509th Operations Group commander Colonel Paul Tibbets, was launched from North Field airbase on Tinian in the West Pacific, about six hours flight time from Japan. The Enola Gay (named after Colonel Tibbets' mother) was accompanied by two other B29s, The Great Artiste which carried instrumentation, commanded by Charles W. Sweeney, and a then-nameless aircraft later called Necessary Evil (B-29) (the photography aircraft) commanded by Captain George Marquardt.

After leaving Tinian the aircraft made their way separately to Iwo Jima where they rendezvoused at 2440 m (8000 ft) and set course for Japan. The aircraft arrived over the target in clear visibility at 9855 m (32,000 ft). On the journey, Navy Captain William Sterling Parsons had armed the bomb, which had been left unarmed to minimize the risks during takeoff. His assistant, 2nd Lt. Morris Jeppson, removed the safety devices 30 minutes before reaching the target area.

The release at 08:15 (Hiroshima time) was uneventful, and the gravity bomb known as "Little Boy", a gun-type fission weapon with 60 kg (130 pounds) of uranium-235, took 57 seconds to fall from the aircraft to the predetermined detonation height about 600 meters (2,000 ft) above the city. It created a blast equivalent to about 13 ton of TNT equivalent. (The U-235 weapon was Nuclear weapon design#Efficiency, with only 1.38% of its material fissioning.) The radius of total destruction was about 1.6 km (1 mile), with resulting fires across 11.4 km² (4.4 square miles). Infrastructure damage was estimated at 90 percent of Hiroshima's buildings being either damaged or completely destroyed.

About an hour before the bombing, Japanese early warning radar detected the approach of some American aircraft headed for the southern part of Japan. An alert was given and radio broadcasting stopped in many cities, among them Hiroshima. 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 conserve fuel and aircraft, the Japanese had decided not to intercept small formations. 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.

Japanese realization of the bombing

The Tokyo control operator of the Japanese Broadcasting Corporation noticed that the Hiroshima station had gone off the air. He tried to re-establish his program by using another telephone line, but it too had failed. About twenty minutes later the Tokyo railroad telegraph center realized that the main line telegraph had stopped working just north of Hiroshima. From some small railway stops within 16 kilometers (10 mi) of the city came unofficial and confused reports of a terrible explosion in Hiroshima. All these reports were transmitted to the headquarters of the Japanese General Staff.

Military bases repeatedly tried to call the Army Control Station in Hiroshima. The complete silence from that city puzzled the men at headquarters; they knew that no large enemy raid had occurred and that no sizable store of explosives was in Hiroshima at that time. A young officer of the Japanese General Staff was instructed to fly immediately to Hiroshima, to land, survey the damage, and return to Tokyo with reliable information for the staff. It was generally felt at headquarters that nothing serious had taken place and that it was all a rumor.

The staff officer went to the airport and took off for the southwest. After flying for about three hours, while still nearly 100 miles (160 km) from Hiroshima, he and his pilot saw a great cloud of smoke from the bomb. In the bright afternoon, the remains of Hiroshima were burning. Their plane soon reached the city, around which they circled in disbelief. A great scar on the land still burning and covered by a heavy cloud of smoke was all that was left. They landed south of the city, and the staff officer, after reporting to Tokyo, immediately began to organize relief measures.

Tokyo's first knowledge of what had really caused the disaster came from the White House public announcement in Washington, D.C., sixteen hours after the nuclear attack on Hiroshima. The press release, it should be noted, was written not by Truman but primarily by William L. Laurence, a New York Times reporter allowed access to the Manhattan Project.

By August 8, 1945, newspapers in the US were reporting that broadcasts from Radio Tokyo had described the destruction observed in Hiroshima. "Practically all living things, human and animal, were literally seared to death," Japanese radio announcers said in a broadcast captured by Allied sources.

Post-attack casualties According to most estimates, the bombing of Hiroshima killed approximately 70,000 people due to immediate effects of the blast. Estimates of total deaths by the end of 1945 range from 90,000 to 140,000, due to burns, radiation and related disease, aggravated by lack of medical resources.{{cite web| url = http://www.ibiblio.org/hyperwar/AAF/USSBS/AtomicEffects/AtomicEffects-2.html | title = Chapter II: The Effects of the Atomic Bombings | year= 1946 | work= United States Strategic Bombing Survey | pages= | publisher= Originally by [United States Government Printing Office; stored on [ibiblio | accessdate = 2007-09-18 -->Some estimates state up to 200,000 may have died by 1950, due to cancer and other long-term effects.Another review and analysis of the various death toll estimates is in:{{cite book| author=Richard B.

Survival of some structures Some of the reinforced concrete buildings in Hiroshima were very strongly constructed because of the earthquake danger in Japan, and their framework did not collapse even though they were fairly close to the center of damage in the city. Akiko Takakura was among the closest survivors to the hypocenter of the blast. She had been in the strongly built Bank of Hiroshima only 300m from ground-zero at the time of the attack. Since the bomb detonated in the air, the blast was more downward than sideways, which was largely responsible for the survival of the Prefectural Industrial Promotional Hall, now commonly known as the Genbaku, or A-bomb Dome designed and built by the Czech Republic architect Jan Letzel, which was only 150 meters (490 feet) from ground zero (the hypocenter). The ruin was named Hiroshima Peace Memorial and made a UNESCO World Heritage site in 1996 over the objections of the United States and China.

Events of August 7-9 After the Hiroshima bombing, President Truman announced, "If they do not not accept our terms, they may expect a rain of ruin from the air the likes of which has never been seen on this earth." On August 8 1945, leaflets were dropped and warnings were given to Japan by Radio Saipan. (The area of Nagasaki did not receive warning leaflets until August 10, though the leaflet campaign covering the whole country was over a month into its operations.)

The Japanese government still did not react to the Potsdam Declaration. Emperor Hirohito, the government and the War council were considering four conditions for surrender: the preservation of the kokutai (Imperial institution and national polity), assumption by the Imperial Headquarters of responsibility for disarmament and demobilization, no occupation and delegation to the Japanese government of the punishment of war criminals.

The Soviet Foreign Minister Vyacheslav Molotov informed Tokyo of the Soviet Union's unilateral abrogation of the Soviet-Japanese Neutrality Pact on April 5. At two minutes past midnight on August 9, Japan Standard Time, Soviet infantry, armor, and air forces Operation August Storm. Four hours later, word reached Tokyo that the Soviet Union had declared war on Japan. The senior leadership of the Imperial Japanese Army began preparations to impose martial law on the nation, with the support of Minister of War Korechika Anami, in order to stop anyone attempting to make peace.

Responsibility for the timing of the second bombing was delegated to Colonel Tibbets as commander of the 509th Bomb Wing on Tinian. Scheduled for August 11 against Kokura, the raid was moved forward to avoid a five day period of bad weather forecast to begin on August 10. Three bomb pre-assemblies had been transported to Tinian, labeled F-31, F-32, and F-33 on their exteriors. On August 8 a dress rehearsal was conducted off Tinian by Maj. Charles Sweeney using Bockscar as the drop airplane. Assembly F-33 was expended testing the components and F-31 was designated for the mission August 9.{{cite book| author=Richard H.

Nagasaki Nagasaki during World War II (Catholic Church in Nagasaki) in January, 1946, destroyed by the atomic bomb, the dome of the church having toppled off.The city of Nagasaki had been one of the largest sea ports in southern Japan and was of great wartime importance because of its wide-ranging industrial activity, including the production of wikt:ordnance, ships, military equipment, and other war materials.

In contrast to many modern aspects of Hiroshima, the bulk of the residences were of old-fashioned Japanese construction, consisting of wood or wood-frame buildings, with wood walls (with or without plaster), and tile roofs. Many of the smaller industries and business establishments were also housed in buildings of wood or other materials not designed to withstand explosions. Nagasaki had been permitted to grow for many years without conforming to any definite city zoning plan; residences were erected adjacent to factory buildings and to each other almost as closely as possible throughout the entire industrial valley.

Nagasaki had never been subjected to large-scale bombing prior to the explosion of a nuclear weapon there. On August 1, 1945, however, a number of conventional high-explosive bombs were dropped on the city. A few hit in the shipyards and dock areas in the southwest portion of the city, several hit the Mitsubishi Steel and Arms Works and six bombs landed at the Nagasaki Medical School and Hospital, with three direct hits on buildings there. While the damage from these bombs was relatively small, it created considerable concern in Nagasaki and many people—principally school children—were evacuated to rural areas for safety, thus reducing the population in the city at the time of the nuclear attack.

To the north of Nagasaki there was a camp holding Commonwealth of Nations prisoners of war, some of whom were working in the coal mines and only found out about the bombing when they came to the surface. At least eight known POWs died from the bombing.As many as 13 POWs may have died in the Nagasaki bombing:

The bombing For the composition of the USAAF mission see 509th Operations Group#Mission compositions. On the morning of August 9, 1945, the U.S. B-29 Superfortress Bockscar, flown by the crew of 393rd Squadron commander Major Charles W. Sweeney, carried the nuclear bomb code-named "Fat Man", with Kokura as the primary target and Nagasaki the secondary target. The mission plan for the second attack was nearly identical to that of the Hiroshima mission, with two B-29's flying an hour ahead as weather scouts and two additional B-29's in Sweeney's flight for instrumentation and photographic support of the mission. Sweeney took off with his weapon already armed but with the electrical safety plugs still engaged.

Observers aboard the weather planes reported both targets clear. When Sweeney's aircraft arrived at the assembly point for his flight off the coast of Japan, the third plane (flown by the group's Operations Officer, Lt. Col. James I. Hopkins, Jr.) failed to make the rendezvous. Bockscar and the instrumentation plane circled for forty minutes without locating Hopkins. Already thirty minutes behind schedule, Sweeney decided to fly on without Hopkins.

By the time they reached Kokura a half hour later, a 7/10 cloud cover had obscured the city, prohibiting the visual attack required by orders. After three runs over the city, and with fuel running low because a transfer pump on a reserve tank had failed before take-off, they headed for their secondary target, Nagasaki. Fuel consumption calculations made en route indicated that Bockscar had insufficient fuel to reach Iwo Jima and they would be forced to divert to Okinawa. After initially deciding that if Nagasaki were obscured on their arrival they would carry the bomb to Okinawa and dispose of it in the ocean if necessary, the weaponeer Navy Commander Frederick Ashworth decided that a radar approach would be used if the target was obscured.

At about 07:50 Japanese time, an air raid alert was sounded in Nagasaki, but the "all clear" signal was given at 08:30. When only two B-29 Superfortresses were sighted at 10:53, the Japanese apparently assumed that the planes were only on reconnaissance and no further alarm was given.

A few minutes later, at 11:00, the support B-29 flown by Captain Frederick C. Bock dropped instruments attached to three parachutes. These instruments also contained an unsigned letter to Professor Ryokichi Sagane, a nuclear physicist at the University of Tokyo who studied with three of the scientists responsible for the atomic bomb at the University of California, Berkeley, urging him to tell the public about the danger involved with these weapons of mass destruction. The messages were found by military authorities but not turned over to Sagane until a month later.Lillian Hoddeson, et al, Critical Assembly: A Technical History of Los Alamos During the Oppenheimer Years, 1943-1945 (New York: Cambridge University Press, 1993), on 295. In 1949 one of the authors of the letter, Luis Alvarez, met with Sagane and signed the document.



At 11:01, a last minute break in the clouds over Nagasaki allowed Bockscar's bombardier, Captain Kermit Beahan, to visually sight the target as ordered. The "Fat Man" weapon, containing a core of ~6.4 kg (14.1 lbs.) of Plutonium, was dropped over the city's industrial valley. 43 seconds later it exploded 469 meters (1,540 ft) above the ground exactly halfway between the Mitsubishi Steel and Arms Works in the south and the Mitsubishi-Urakami Ordnance Works (Torpedo Works) in the north. This was nearly 3 kilometers (2 mi) northwest of the planned hypocenter; the blast was confined to the Urakami and a major portion of the city was protected by the intervening hills. The resulting explosion had a blast yield equivalent to 21 kilotons of TNT equivalent. The explosion generated heat estimated at 7000 degrees Fahrenheit and winds that were estimated at 624 mph.

An unknown number of survivors from the Hiroshima bombing made their way to Nagasaki and were bombed again.

Plans for more atomic attacks on Japan The United States expected to have another atomic bomb ready for use in the third week of August, with three more in September and a further three in October.{{cite web]| coauthors General Hull Colone Seazen| format = pdf| work = National Security Archive Electronic Briefing Book No. 162| url = http://www.gwu.edu/~nsarchiv/NSAEBB/NSAEBB162/72.pdf-->On August 10, Major General Leslie Groves, military director of the Manhattan Project, sent a memorandum to General of the Army George Marshall, Chief of Staff of the United States Army, in which he wrote that "the next bomb . . should be ready for delivery on the first suitable weather after 17 or 18 August." On the same day, Marshall endorsed the memo with the comment, "It is not to be released over Japan without express authority from the President." There was already discussion in the War Department about conserving the bombs in production until Operation Downfall, the projected invasion of Japan, had begun. "The problem now August is whether or not, assuming the Japanese do not capitulate, to continue dropping them every time one is made and shipped out there or whether to hold them . . . and then pour them all on in a reasonably short time. Not all in one day, but over a short period. And that also takes into consideration the target that we are after. In other words, should we not concentrate on targets that will be of the greatest assistance to an invasion rather than industry, morale, psychology, and the like? Nearer the tactical use rather than other use."

The surrender of Japan and subsequent occupation Up to August 9, the war council was still insisting on its four conditions for surrender. On that day Hirohito ordered Kido to "quickly control the situation" "because Soviet Union has declared war against us". He then held an Imperial conference during which he authorized minister Shigenori Togo to notify the Allies that Japan would accept their terms on one condition, that the declaration "does not compromise any demand which prejudices the prerogatives of His Majesty as a Sovereign ruler".Kido Koichi nikki,Tokyo, Daigaku Shuppankai, 1966, p.1223

On August 12, the Emperor informed the imperial family of his decision to surrender. One of his uncles, Prince Asaka, then asked whether the war would be continued if the kokutai could not be preserved. Hirohito simply replied "of course".Terasaki Hidenari, Shôwa tennô dokuhakuroku, 1991, p.129 As the Allied terms seemed to leave intact the principle of the preservation of the Throne, Hirohito recorded on August 14 his capitulation announcement which was broadcast to the Japanese nation the next day despite a short rebellion by fanatic militarists opposed to the surrender.

In his declaration, Hirohito referred to the atomic bombings :{{cquote], he stressed the impact of the Soviet invasion and his decision to surrender, omitting any mention of the bombs.

During the year after the bombing, approximately 40,000 U.S. occupation troops were in Hiroshima. Nagasaki was occupied by 27,000 troops. More that 40,000 members of the British Commonwealth Occupation Force were also in Japan.

Atomic Bomb Casualty Commission In the spring of 1948, the Atomic Bomb Casualty Commission (ABCC) was established in accordance with a presidential directive from Harry S. Truman to the United States National Academy of Sciences-United States National Research Council to conduct investigations of the late effects of radiation among the survivors in Hiroshima and Nagasaki. One of the early studies conducted by the ABCC was on the outcome of pregnancies occurring in Hiroshima and Nagasaki, and in a Controlling for a variable city, Kure, Hiroshima located 18 miles south from Hiroshima, to discern the conditions and outcomes related to radiation exposure. Some would say ABCC was not in a position to offer medical treatment to the survivors except in a research capacity. One author has claimed that the ABCC refused to provide medical treatment to the survivors for better research results. In 1975, the Radiation Effects Research Foundation was created to assume the responsibilities of ABCC.

The Hibakusha The surviving victims of the bombings are called , a Japanese word that literally translates to "explosion-affected people". The suffering of the bombing is the root of Japan's postwar pacifism , and the nation has sought the abolition of nuclear weapons from the world ever since.As of 2007, there were 251,834 hibakusha recognized by the Japanese government; most live in Japan.{{cite web| url= http://www.kuna.net.kw/NewsAgenciesPublicSite/ArticleDetails.aspx?id=1832635&Language=en | title= "Hiroshima marks 62nd A-bomb anniversary" | date= 8/6/2007 | publisher= [Kuwait News Agency | accessdate = 2007-10-02 -->The government of Japan recognizes about 1% of these as having illnesses caused by radiation.{{cite web| url= http://search.japantimes.co.jp/cgi-bin/ed20070815a2.html | title= "Relief for A-bomb victims" (editorial) | date= Aug. 15, 2007 | publisher= ''[The Japan Times'' | accessdate= 2007-10-02 -->The memorials in Hiroshima and Nagasaki contain lists of the names of the hibakusha who are known to have died since the bombings.

Korean survivors During the war Japan brought many Korean conscripts to both Hiroshima and Nagasaki to work as forced labor. According to recent estimates, about 20,000 Koreans were killed in Hiroshima and about 2,000 died in Nagasaki. It is estimated that one in seven of the Hiroshima victims was of Korean ancestry.Mikiso Hane. Modern Japan: A Historical Survey. Boulder: Westview Press, 1992. For many years Koreans had a difficult time fighting for recognition as atomic bomb victims and were denied health benefits. Though such issues have been addressed in recent years, issues regarding recognition linger.

Debate over bombings Those who argue in favor of the decision to drop the bombs generally assert that the bombings ended the war months sooner than would otherwise have been the case, thus saving many lives. It is argued that there would have been massive casualties on both sides in the Operation Downfall invasion of Japan, and that even if Operation Downfall was postponed, the status quo of conventional bombings and the Japanese occupations in Asia were causing tremendous loss of life.

A number of notable individuals and organizations have criticized the bombings, many of them characterizing them as war crimes or crimes against humanity and/or state terrorism. Two early critics of the bombings were Albert Einstein and Leo Szilard, who had together spurred the first bomb research in 1939 with a Einstein-Szilard letter to President Roosevelt. Szilard, who had gone on to play a major role in the Manhattan Project, argued: "Let me say only this much to the moral issue involved: Suppose Germany had developed two bombs before we had any bombs. And suppose Germany had dropped one bomb, say, on Rochester, New York and the other on Buffalo, New York, and then having run out of bombs she would have lost the war. Can anyone doubt that we would then have defined the dropping of atomic bombs on cities as a war crime, and that we would have sentenced the Germans who were guilty of this crime to death at Nuremberg and hanged them?" (republished at , reached through Leo Szilard page at )
