Since Mayor Senkichi Awaya had been killed while eating breakfast with his son and granddaughter at the mayoral residence, Field Marshal Shunroku Hata, who was only slightly wounded, took over the administration of the city, and coordinated relief efforts. Many of his staff had been killed or fatally wounded, including Lieutenant Colonel Yi U, a prince of the Korean imperial family who was serving as a General Staff Officer. Hata's senior surviving staff officer was the wounded Colonel Kumao Imoto, who acted as his chief of staff. Soldiers from the undamaged Hiroshima Ujina Harbor used Shin'yō-class suicide motorboats, intended to repel the American invasion, to collect the wounded and take them down the rivers to the military hospital at Ujina. Trucks and trains brought in relief supplies and evacuated survivors from the city.
