Atomic bombings of Hiroshima and Nagasaki
Most elements of the Japanese Second General Army headquarters were at physical training on the grounds of Hiroshima Castle, barely from the hypocenter. The attack killed 3,243 troops on the parade ground. The communications room of Chugoku Military District Headquarters that was responsible for issuing and lifting air raid warnings was in a semi-basement in the castle. Yoshie Oka, a Hijiyama Girls High School student who had been mobilized to serve as a communications officer had just sent a message that the alarm had been issued for Hiroshima and neighboring Yamaguchi, when the bomb exploded. She used a special phone to inform Fukuyama Headquarters (some away) that "Hiroshima has been attacked by a new type of bomb. The city is in a state of near-total destruction."
