"Truman and Hirohito: a former farmer and a socially awkward monarch. Upon the shoulders of this unlikely pair rested the fate of two nations and millions of lives." The unassuming and virtually unknown Truman became president on the afternoon of April 12th. Twelve days later, the Secretary of War briefed him on the Manhattan Project. Throughout the spring, planning for completion of the weapon continued, training for the delivery of the heavy bombs was conducted, and the targeting of cities analyzed.
That spring, Japan's 44-year-old emperor sat in his palace and brooded as the city of Tokyo burned around him. The nation was being battered on every front, the war was obviously lost, and, most importantly, the people were giving up as they slowly starved to death. The very first firebombing of Tokyo in March killed 100,000, destroyed 260,000 buildings, and left a million homeless.
Truman had to find the best way to end the war, and end it with the fewest American casualties. Gen. Marshall wanted to invade the home islands, and Adm. King preferred a blockade. Gen. LeMay thought that firebombing the cities would lead to surrender. On June 18th, the JCS recommended an invasion by 766,700 Americans, and Truman agreed. The same day, Hirohito met with the military council and told them that they needed to find a way to end the war.
The president traveled to Potsdam, Germany, to meet Churchill and Stalin. He wanted the USSR to keep its promise to enter the war against Japan. On July 16th, at 5:30 a.m. in New Mexico, the US successfully tested the first atomic bomb. When someone observed that the war was over, Gen. Groves said, "After we drop two bombs on Japan."
Ongoing intelligence intercepts indicated Japan would fight and not accept unconditional surrender. Faced with the success of the bomb's test and fearing innumerable American casualties, Truman made the decision to drop the bomb at some point between July 22nd and 24th while in Potsdam. A final ultimatum, which used the phrase "the unconditional surrender of the Japanese armed forces," not of the country itself, was ignored by Japan. The die was cast, and the focus turned from Washington and Potsdam to Tinian, the home of the 509th Composite Group.
On August 6th, thirty-year-old Col. Paul Tibbets took off in a specially modified B-29 carrying the 9,700-pound bomb. Tibbets had flown the 8th Air Force's first raid over France three years earlier. The bombardier released the Little Boy at 9:14 a.m. The airmen could see the mushroom cloud from 400 miles away.
The president learned of the news in the middle of his Atlantic crossing; he announced the results to the jubilant crew of the Augusta. A prepared press release was issued in Washington. It said that Japan would be totally destroyed. In Tokyo, there was confusion as the army downplayed the bomb and the emperor demanded peace. On Tinian, Fat Man was prepared for August 9th, and it was released over Nagasaki at 11:58 a.m.
Even the news of the second bomb did not convince the cabinet to surrender, and Hirohito agreed to meet them at midnight. After two and a half more hours of debate, they finally asked the emperor his thoughts. He stood. "I have given serious thought to the situation prevailing at home and abroad and have concluded that continuing the war can only mean destruction for the nation and a prolonging of bloodshed and cruelty in the world. It goes without saying that it is unbearable for me to see the brave fighting men of Japan disarmed. It is equally unbearable that others who have rendered me devoted service should now be punished as instigators of war. Nevertheless, the time has come that we must bear the unbearable."
The following morning, Radio Tokyo broadcast an acceptance of terms but asked for a retention of the emperor's prerogatives. The US responded that the emperor would be "subject to" the supreme commander. The army and navy chiefs went to the palace and stated that they did not wish to surrender. There was fear in the city that junior officers would rebel and even kidnap Hirohito. On the 14th, he again told the military's leaders to surrender, and that he would address the nation by radio, stating the war was over. At that point, the senior leaders bowed to his command. The army chief asserted, "No officer in the Imperial Army will disobey the emperor's command." Hirohito recorded his speech that night. Hirohito's broadcast was made to the nation at noon on the 15th. The people of Japan had never heard his voice, as he told them they were accepting the terms of the Potsdam Declaration. Japan had lost, the war was over, and he directed the armed forces to surrender and sign all required documents presented by the Allies.
For eight decades, the question of the necessity of bombing Hiroshima and Nagasaki has been debated. Those opposed speak to the inhumanity of it all, and argue that Japan would have surrendered anyway. Proponents say the attack on Pearl Harbor, the brutalities inflicted on the Bataan Death March, along with their horrific occupation of much of eastern Asia for four years justified the punishment inflicted. Furthermore, there were 900,000 men preparing to defend Kyushu in the expected November 1945 invasion. The Department of War manufactured 500,000 Purple Hearts that were never awarded. I personally believe the saving of American lives and the immediate cessation of hostilities justified Truman's decision. This is a brilliant, and highly recommended, history book.
