The peace side decided to counteract the martial effect of that news release with an announcement of their own. This was for several reasons. The government sponsored news agency was in Morse code only and not covered by military censorship; it would speed the receipt of the Japanese offer going through diplomatic channels and could possibly postpone destruction of another city; and it was hoped that rejoicing created among the allies by an end to the war would make them unable to reject Japan's counter offer. On the morning of the 11th, the army was furious, but did not resort to violence. That evening the Emperor agreed to broadcast to the nation on acceptance of the offer.
The stern Allied response, written by the Americans and approved by the Allies, was also released by radio news to let Japan know under what terms the agreement was accepted. It was received about midnight August 11-12, eighteen hours before the diplomatic note. As word spread within the government, about midnight of the 13th, a plea was made to commit twenty million lives (kamikaze) to victory. On the morning of the 14th Allied leaflets erased the secrecy of the negotiations. Noon on the 14th saw another imperial conference in which the three military leaders in the cabinet spoke for rejection. The Emperor considered the Allied response to be acceptable. The cabinet met immediately after and endorsed the Emperor's wishes, thereby making the acceptance legal. By three in the afternoon, the government Morse code station announced that an "acceptance will be forthcoming soon." The Allies stopped attacks and went on alert status.
Insurgents assassinated the commander of the Imperial Guards and issued orders under his name, but the insurrection was put down by morning. Separately, the War Minister committed suicide. Also overnight, the Emperor recorded his address to the nation which was broadcast at noon, 15 August. Wording was so carefully drafted, about saving innocent lives from a new and cruel bomb, that it was not immediately known that it meant full surrender. The cabinet resigned as a duty and an Imperial Prince was made premier.
That is interesting!
I wish I'd listened more to history when I was young. I can't understand why I didn't find it fascinating back then!
