Os bombardeamentos de Hiroxima e Nagasaki

How A Last-Minute Decision Led To The Nuking Of Nagasaki, na Business Insider:

The preference was for a large urban area with closely built wooden-frame buildings densely populated by Japanese civilians. The project’s target committee recommended detonation at altitude to achieve maximum blast damage.

Five cities were proposed as targets: Kyoto, Hiroshima, Yokohama, Kokura and Niigata. The armed forces were instructed to exclude these cities from conventional firebombing: the project director, General Leslie Groves of the US Army Corps of Engineers, and his team of scientists wanted a 'clean’ background so the effect of the bomb could be easily assessed. They also wanted visual targeting without cloud cover so damage could be photographed.

Henry Stimson, the US Secretary of War, was concerned that America’s reputation for fair play might be damaged by targeting urban areas. General George Marshall had a similar view, believing the bomb should be used first on military targets and only later on large manufacturing areas after first warning the surrounding population to leave. Both men’s views were ignored.

People in Hiroshima became aware that their city was not being subjected to the incendiary attacks of other cities. A rumour spread that President Truman’s mother had been imprisoned in Hiroshima Castle, that the American military had been instructed to spare the city.

Groves’s first choice was Kyoto. It was largely untouched by bombing and was psychologically important to the Japanese. Its surrounding mountains would focus the blast and thereby increase the bomb’s destructive force.

Stimson, who had visited Kyoto in the 1920s, knew its status as Japan’s intellectual and cultural capital and considered its destruction to be barbaric. He argued for Kyoto to be dropped from the list and eventually won Truman over to his view.

On July 25 1945 General Thomas Handy issued on their behalf an order to General Carl Spaatz, the Guam-based commander of US Army Strategic Air Forces, to 'deliver’ the first 'special bomb’ as soon after August 3 as weather permitted visual targeting. The target was to be selected from a list of four: Hiroshima, Kokura, Niigata and, added that day, Nagasaki.

The sub-committee had decided not to specify military-industrial areas as targets since they were scattered, and – apart from Kokura, which had a huge munitions factory in the middle of the city – generally on the suburban fringes. Aircrews were to select their own targets to maximise the effect on a city as a whole. The greatest impact would be achieved by aiming at the centre of a city, where the population was densest.

It wasn’t clear how the mass killing of civilians would drive the Japanese to capitulate. Japan’s cities had been firebombed since March, setting a precedent for targeting non-combatants, without any surrender resulting. Stimson had to settle for persuading himself that the project was not intentionally targeting civilians, in the face of clear evidence to the contrary.
