Catalogue ref: FO 371/59640

The accentuated effect of these bombs came not only from their surprise and their crushing power, but also from the feeling of security among the inhabitants of the two cities before the attacks. Though Nagasaki had undergone five raids in the previous year, they had not been heavy, and Hiroshima had gone almost untouched until the morning of 6 August 1945. In both cities many people felt that they would be spared and the various rumours in circulation supporting such feeling covered a wide range of wishful thoughts. There were so many Christians

Typical comments of survivors were:

"If the enemy has this type of bomb, everyone is going to die, and we wish the war would hurry and finish."

Of greater significance are the reactions of Japanese people as a whole. The two raids were all-Japan events and were intended so: the Allied powers were trying to break the fighting spirit of the Japanese people and their leaders, not just the residents of Hiroshima and Nagasaki. Virtually all the Japanese people had a chance to react to the bomb, though the news had not reached to full spread at the time of the surrender. By the time the interviewing was done. Only about two percent of the population in rural areas and one percent in the cities had not heard of the bomb.
