I thought there were only two myself. I just watched a History Channel show about the last days of World War II, and they indicated that there was a define plan to drop a third bomb in Ausgust, if the Japanese did not agree to surrender.
I know Truman drafted a letter to the Prime Minister of Great Britain telling him that the U.S. intended to drop an A-Bomb on Tokyo if the Japanese did not surrender, despite British objections. The “Tokyo Bomb” was only in the planning stages, there was no date set for its deployment, but I believe that Truman would have nuked Tokyo before he attempted an invasion of Japan.
So Tokyo was to be the target of the third one?
"Providing there are no unforeseen difficulties in manufacture, in transportation to the theatre or after arrival in the theatre, the next bomb should be ready for delivery on the first suitable weather after 17 or 18 August."
I wish we would have hit Tokyo first. Destroyed their whole image of emperor as god.
Course Tokyo got firebombed very badly and iirc 100,000 or so died. The nuke would have cracked their will to keep going right away with a dead nuked emperor false god destroyed.
