The Storm of War - Andrew Roberts [326]
To those who argued that the enemy ought to have been warned about the destructive power of the atomic bombs, or even had one demonstrated in a desert or an atoll beforehand, General Marshall succinctly noted: ‘It’s no good warning him. If you warn them there’s no surprise. And the only way to produce shock is surprise.’23 With only two bombs available, to risk wasting one to no effect was inconceivable. President Truman made a radio broadcast soon afterwards, explaining that the bomb had been atomic, and thus unlike anything that had ever been seen before. ‘That bomb had more power than 20,000 tons of T.N.T.’ (that is, 20 kilotons), he told his listeners, which included the Japanese Government. ‘It had more than two thousand times the blast power of the [22,000-pound deep-penetration] British “Grand Slam”, which is the largest bomb ever used in the history of warfare.’24 (It was long thought that Truman was accurate, and that the bomb dropped on Nagasaki was roughly the same size in terms of TNT, but in 1970 the British nuclear pioneer Lord Penney proved that Hiroshima’s blast had in fact been about 12 kilotons, while the Nagasaki blast had been around 22 kilotons.) 25
George MacDonald Fraser’s views on the morality of what had happened at Hiroshima echoed those of the vast majority of Britons and Americans at the time, both civilian and military. He pointed out that:
We were of a generation to whom Coventry and the London Blitz and Clydebank and Liverpool and Plymouth were more than just names; our country had been hammered mercilessly from the sky, and so had Germany; we had seen the pictures of Belsen and of the frozen horror of the Russian Front; part of our higher education had been dedicated to techniques of killing and destruction; we were not going to lose sleep because the Japanese homeland had taken its turn. If anything, at the time, remembering the kind of war it had been, and the kind of people we, personally, had been up against, we probably felt that justice had been done. But it was of small importance when weighed against the glorious fact that the war was over at last.26
Almost, but not quite. In fact the Japanese Government decided to fight on regardless, hoping that the Allies had only one such weapon and believing that the home islands could be successfully defended from invasion and the dishonour of occupation.27 So three days after Hiroshima, the city of Nagasaki was similarly devastated by Fat Man, with 73,884 people killed, 74,909 injured and similarly debilitating long-term mental and physical effects on the population as at Hiroshima, owing to the radiation released.28 (It almost didn’t happen; the B-29 pilot Major Charles ‘Chuck’ Sweeney nearly ran out of runway on Tinian with his 5-ton bomb on board, and a crash would have wiped out much of the island.) 29
Not knowing that the Americans had no more atomic bombs to drop, and shocked by Russia’s intervention in the Pacific War on 8 August, which they were unable effectively to counter, the Japanese did finally surrender on 14 August, with the Emperor Hirohito admitting to his people in a broadcast at noon the next day that the war had gone ‘not necessarily to Japan’s advantage’, especially in view of ‘a new most cruel bomb’.30 Even as he prepared to broadcast, a group of young officers invaded the palace grounds in an attempted coup intended to prevent him from doing so.31
