For the entire story on-line, see:General Buckner then invited Ushijima to enter negotiations for surrender. No one seriously expected Ushijima to respond to this bid for surrender. Two days later planes scattered another 30,000 leaflets over enemy ground, this time emphasizing Ushijima's refusal to negotiate for surrender and his selfish determination to commit his entire army to destruction, and calling upon his subordinate officers and men to quit of their own accord. Another appeal was made on 14 June.
Actually, it was later learned, General Ushijima did not receive the original message until 17 June, the delay resulting from the lack of communications and the general confusion existing among his troops. Both he and his chief of staff, General Cho, considered the message hilariously funny and said that it would not be consonant with their honor as Samurai to entertain such a proposal.18 (My Emphasis)
