The explosion effect of the bombs with an explosive yield of 13 and/or 25 kilotons TNT equivalent and the fires after the explosions destroyed large parts of the two cities.

After the first test of an atom bomb in the Alamogordo desert in new Mexico to 16. July 1945 (Trinity test) were this the second and third atomic explosion at all and the so far only atom bomb releases in a war.

decision for bombardment

the decision over an ultimatum at Japan fell to the Potsdamer conference (17. July - 2. August 1945) of winner powers in the war against Germany in July 1945. It was affected by the height of the past American losses in the war against Japan and the losses which can be expected in the case of an invasion and an occupation of the country. Japan had lost and could at this time nearly its entire fleet, the main part of air forces and most of the conquered areas only for favorable peace conditions while maintaining the national sovereignty hope. For a landing on the Japanese Hauptinseln indicated American of military an expected Verlustzahl of 60.000 soldiers. After death the Franklin D. Roosevelts in April 1945 acting new US president Harry S. Truman gave to 26. July 1945 in the name of the USA, which Republic of China under Chiang dock shek and the united Kingdom of the Potsdamer explanation off, in which it requested the Japanese guidance for immediate and unconditional surrender. Already two days before, to 24. July, was the instruction for the preparation of the attack on Hiroshima for the 3. August been issued to the responsible commander, general Carl Spaatz.

Trumans explanation did not contain referring to the planned employment of the new weapon, but white only in consciously aggressive form on the superior military power of the allied ones and their determination to the fight up to the complete destruction of Japan. In May 1945 furnished American Interim Committee for the development of suggestions for the use of the atom bombs manufactured in the Manhattan project had to 2. June the recommendation expressed to use the weapons immediately after their completion and without preliminary warning against goals of the Japanese Kriegsindustrie without attention of possible civilian victims. However at least one of the members of the committee, the Untersekretär in the war Ministry Ralph Bard, expressed clear doubts to use the weapons completely without preliminary warning.

the release of the bomb Fat one became to 9. August 1945 accomplished by the bomber Bockscar, which belonged to the 509th Composite Group stationed on Tinian. As a goal originally the city Kokura was intended, due to more closely cloudy appearance however after three unsuccessful approaches the secondary target Nagasaki was attacked. Since here likewise bad visibilities prevailed, no accurate goal release could be accomplished. The instructions actually read under such circumstances to break the release off the pilot decided however for an approach of radar.

The bomb was dropped around 11:02 clock several hundred meters off the planned discharging point on closely inhabited area; actually a direct attack on the Mitsubishi Rüstungsbetriebe was planned. The explosion into approximately 470 meters of Bodenhöhe destroyed 80 per cent of all buildings in the periphery of a kilometer and left only few survivors. „Fat one “detonated in a valley, so that the surrounding mountains absorbed the effects on the environment of the city. Altogether died however about 75,000 humans at the direct sequences of the explosion, which kt with an explosive yield of 22 TNT over a distance of 4 kilometers of objects in fire set and which nearly only from timber buildings existing city gradened to a large extent.

to 15. August 1945, six days after the second atom bomb release, was radiated an explanation of the Tennōs over the completion of the war, in which it recognized the conditions of the Potsdamer explanation. This day was celebrated as V-J Day (Victory over Japan). The documents over the surrender of Japan became to 2. September signatoryly by the Japanese military guidance, the mainland army capitulated to 9. September. Thus the Second World War was now also in the East Asian combat area terminated. For Hiroshima and Nagasaki the end of war meant that now foreign assistance, approximately via the red cross, could take place. The US army accomplished a detailed documentation of the bomb damage in the following months under line of the military assigned one for the Manhattan project, general Leslie Groves, in which also scientists and the medical profession participated. The published results were however propagandistically coined/shaped. In particular the radiological effect of the weapons was answered in the negative, which demanded still months after the explosions of ten thousands victims. It becomes estimated that in Hiroshima to end 1945 further 60,000 first survivors succumbed to the consequences of the radioactive contamination as well as burns and other heavy injuries. Until 1950 the number of the late victims in both cities had risen to altogether 230,000, which were most the effects of the primary radioactive contamination to the victim please (see also Hibakusha).
