Atomic Bomb Introduction Vocabulary

1 Atomic Bomb Introduction In the early morning hours of July 16, 1945, great anticipation and fear ran rampant at White Sands Missile Range near Alamogordo, New Mexico. Robert Oppenheimer, director of the Manhattan Project, could hardly breathe. Years of secrecy, research, and tests were riding on this moment. "For the last few seconds, he stared directly ahead and when the announcer shouted Now!' and there came this tremendous burst of light followed abruptly there after by the deep growling of the explosion, his face relaxed into an expression of tremendous relief," recalled General L. R. Groves of Oppenheimer, in a memorandum for Secretary of War George Marshall. The explosion carrying more power than 20,000 tons of TNT and visible for more than 200 miles succeeded. The world's first atomic bomb had been detonated. With the advent of the nuclear age, new dilemmas in the art of warfare arose. The war in Europe had concluded in May. The Pacific war would receive full attention from the United States War Department. As late as May 1945, the U.S. was engaged in heavy fighting with the Japanese at Iwo Jima and Okinawa. In these most bloody conflicts, the United States had sustained more than 75,000 casualties. These victories insured the United States was within air striking distance of the Japanese mainland. The bombing of Pearl Harbor by the Japanese to initiate United States entrance into the war, just four years before, was still fresh on the minds of many Americans. A feeling of vindication and a desire to end the war strengthened the resolve of the United States to quickly and decisively conclude it. President Harry Truman had many alternatives at his disposal for ending the war: invade the Japanese mainland, hold a demonstration of the destructive power of the atomic bomb for Japanese dignitaries, drop an atomic bomb on selected industrial Japanese cities, bomb and blockade the islands, wait for Soviet entry into the war on August 15, or mediate a compromised peace. The Japanese resolve to fight had been seriously hampered in the preceding months. Their losses at Iwo Jima and Okinawa had been staggering. Their navy had ceased to exist as an effective fighting force and the air corps had been decimated. American B-29's made bombing runs over military targets on the Japanese mainland an integral part of their air campaign. Japan's lack of air power hindered their ability to fight. The imprecision of bombing and the use of devastating city bombing in Europe eventually swayed United States Pacific theater military leaders to authorize bombing of Japanese mainland cities. Tokyo, Nagoya, Osaka, and Kobe all were decimated by incendiary and other bombs. In all, hundreds of thousands of civilians were killed in these air strikes meant to deter the resolve of the Japanese people. Yet, Japanese resolve stayed strong and the idea of a bloody "house to house" invasion of the Japanese mainland would produce thousands more American and Allied casualties. The Allies in late July 1945 declared at Potsdam that the Japanese must unconditionally surrender. After Japanese leaders flatly rejected the Potsdam Declaration, President Truman authorized use of the atomic bomb anytime after August 3, On the clear morning of August 6, the first atomic bomb, nicknamed Little Boy, was dropped on the city of Hiroshima. Leveling over 60 percent of the city, 70,000 residents died instantaneously in a searing flash of heat. Three days later, on August 9, a second bomb, Fat Man, was dropped on Nagasaki. Over 20,000 people died instantly. In the successive weeks, thousands more Japanese died from the after effects of the radiation exposure of the blast. Vocabulary Incendiary bomb: The incendiary bomb was a mixture of thermite and oxidizing agents employed by the Allies and Axis powers after Sometimes incorporating napalm, these bombs were responsible for burning over 41.5 square miles of Tokyo by the United States in March Unconditional surrender: Unconditional surrender is a term used by victors in war to describe the type of settlement they wish to extoll from the vanquished. The settlement demands that the loser make no demands during surrender proceedings. Providence: divine guidance or care Ultimatum: The final propositions, conditions, or terms offered by either of the parties during a diplomatic negotiation

6 PROCESS: Write down what you know regarding the dropping of the atomic bombs. ESSENTIAL QUESTION: How should we remember the dropping of the atomic bombs? Source: Excerpts from Three Narratives of our Humanity by John W. Dower, The following is from a book written by a historian about how people remember wars. John W. Dower explains the two different ways that the dropping of the atomic bombs on Hiroshima and Nagasaki is remembered. Hiroshima as Victimization Japanese still recall the war experience primarily in terms of their own victimization. For them, World War II calls to mind the deaths of family and acquaintances on distant battlefields, and, more vividly, the prolonged, systematic bombings of their cities. If it is argued that the nuclear bombing of Hiroshima was necessary to shock the Japanese to surrender, how does one justify the hasty bombing of Nagasaki only three days later, before the Japanese had time to investigate Hiroshima and formulate a response? Hiroshima as Triumph To most Americans, Hiroshima the shattered, atomized, irradiated city remains largely a symbol of triumph marking the end of a horrendous global conflict and the effective demonstration of a weapon that has prevented another world war. It is hard to imagine that the Japanese would have surrendered without the atomic bomb. Japanese battle plans that were in place when the bombs were dropped called for a massive, suicidal defense of the home islands, in which the imperial government would mobilize not only several million fighting men but also millions of ordinary citizens who had been trained and indoctrinated to resist to the end with primitive makeshift weapons. For Japanese to even discuss capitulation (surrender) was seditious (against the law). Guiding Questions 1. In 1-2 sentences each, explain the two narratives (stories) about Hiroshima. 2. Which narrative do you agree with more? Why?

8 Document A: Japan would have fought to the end BBC News. BBC, n.d. Web. 13 Nov Although some Japanese were taken prisoner, most fought until they were killed or committed suicide. In the last, desperate months of the war, this image was also applied to Japanese civilians. To the horror of American troops advancing on Saipan, they saw mothers clutching their babies hurling themselves over the cliffs rather than be taken prisoner. Not only were there virtually no survivors of the 30,000 strong Japanese garrison on Saipan, two out of every three civilians - some 22,000 in all - also died. The other enduring image of total sacrifice is that of the kamikaze pilot, ploughing his plane packed with high explosives into an enemy warship. Even today, the word 'kamikaze' evokes among Japan's former enemies visions of crazed, mindless destruction. What in some cases inspired - and in others, coerced - Japanese men in the prime of their youth to act in such a way was a complex mixture of the times they lived in, Japan's ancient warrior tradition, societal pressure, economic necessity, and sheer desperation. The other enduring image of total sacrifice is that of the kamikaze pilot, ploughing his plane packed with high explosives into an enemy warship. When Japan began its military adventures in China in 1931, it was a society in turmoil. They were indoctrinated from an early age to revere the Emperor as a living deity, and to see war as an act that could purify the self, the nation, and ultimately the whole world. Within this framework, the supreme sacrifice of life itself was regarded as the purest of accomplishments. Document B: Japan was making steps toward peace Zinn, Howard. A People's History of the United States: 1492-present. New York: HarperCollins, Print. The United States Strategic Bombing Survey interviewed hundreds of Japanese civilian and military leaders after Japan surrendered, and reported just after the war: Based on a detailed investigation Japan would have surrendered even if the atomic bombs had not been dropped, even if Russia had not entered the war, and even if no invasion had been planned or contemplated. But could American leaders have known this in August 1945? The answer is, clearly, yes. The Japanese code had been broken, and Japan's messages were being intercepted. It was known the Japanese had instructed their ambassador in Moscow to work on peace negotiations with the Allies. Japanese leaders had begun talking of surrender a year before this, and the Emperor himself had begun to suggest, in June 1945, that alternatives to fighting to the end be considered. On July 13, Foreign Minister Shigenori Togo wired his ambassador in Moscow: "Unconditional surrender is the only obstacle to peace...." Why did the United States not take that small step to save both American and Japanese lives? Was it because too much money and effort had been invested in the atomic bomb not to drop it? General Leslie Groves, head of the Manhattan Project, described Truman as a man on a toboggan, the momentum too great to stop it. Or was it that the United States was anxious to drop the bomb before the Russians entered the war against Japan? In other words, BlaekeIt says, the dropping of the bomb was "the first major operation of the cold diplomatic war with Russia...." Truman had said, "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." It was a preposterous statement. Those 100,000 killed in Hiroshima were almost all civilians. The U.S. Strategic Bombing Survey said in its official report: "Hiroshima and Nagasaki were chosen as targets because of their concentration of activities and population." The dropping of the second bomb on Nagasaki seems to have been scheduled in advance, and no one has ever been able to explain why it was dropped among the Nagasaki dead were probably American prisoners of war. Reports prisoner of war sources, not verified by photos, give location of Allied prisoner of war camp one mile north of center of city of Nagasaki. Does this influence the choice of this target for initial Centerboard operation? Request immediate reply. The reply: "Targets previously assigned for Centerboard remain unchanged."

9 Document C: Thank God for the Atomic Bomb Source: Paul Fussell, a World War II Soldier, Thank God for the Atom Bomb, My division, like most of the ones transferred from Europe was going to take part in the invasion at Honshu (an island of Japan). The people who preferred invasion to A-bombing seemed to have no intention of proceeding to the Japanese front themselves. I have already noted what a few more days would mean to the luckless troops and sailors on the spot... On Okinawa, only a few weeks before Hiroshima, 123,000 Japanese and Americans killed each other. War is immoral. War is cruel. Document D: Stopping Russia Source: James Byrnes was one of Truman's advisors on the atomic bomb. In addition to defeating Japan, he wanted to keep the Soviet Union from expanding its influence in Asia and to limit its influence in Europe. Manhattan Project scientist Leo Szilard met with Byrnes on May 28, Leo Szilard wrote about his meeting with Byrnes in [Byrnes] was concerned about Russia's postwar behavior. Russian troops had moved into Hungary and Romania, and Byrnes thought it would be very difficult to persuade Russia to withdraw her troops from these countries, that Russia might be more manageable if impressed by American military might, and that a demonstration of the bomb might impress Russia. Document E: Survivor Source: Yoshitaka Kawamoto was thirteen years old. He was in the classroom at Zakoba-cho, 0.8 kilometers away from the hypocenter. He is now working as the director of the Hiroshima Peace Memorial Museum, telling visitors from all over the world what the atomic bomb did to the people of Hiroshima. One of my classmates, I think his name is Fujimoto, he muttered something and pointed outside the window,saying, "A B-29 is coming." He pointed outside with his finger. So I began to get up from my chair and asked him, "Where is it?" Looking in the direction that he was pointing towards, I got up on my feet, but I was not yet in an upright position when it happened. All I can remember was a pale lightening flash for two or three seconds. Then, I collapsed. I don t know much time passed before I came to. It was awful, awful. The smoke was coming in from somewhere above the debris. Sandy dust was flying around... I crawled over the debris, trying to find someone who were still alive. Then, I found one of my classmates lying alive. I held him up in my arms. It is hard to tell, his skull was cracked open, his flesh was dangling out from his head. He had only one eye left, and it was looking right at me.... he told me to go away. I, so, was running, hands were trying to grab my ankles, they were asking me to take them along. I was only a child then. And I was horrified at so many hands trying to grab me. I was in pain, too. So all I could do was to get rid of them, it s terrible to say, but I kicked their hands away. I still feel bad about that. I went to Miyuki Bridge to get some water. At the river bank, I saw so many people collapsed there... I was small, so I pushed on the river along the small steps. The water was dead people. I had to push the bodies aside to drink the muddy water. We didn't know anything about radioactivity that time. I stood up in the water and so many bodies were floating away along the stream. Document F: Casualties Hiroshima: 60,000 civilians were initially killed 135,000 would die from injuries and illness later Nagasaki: 40,000 civilians were initially killed 10,000 more would die from injuries and illness later There is evidence that American POWs were among the dead
