"In honor of Emperor Hirohito's thirty-seventh birthday, Japanese generals sent fifty planes to bomb Hankow. The planes were met by twenty-three Chinese planes. For an hour, a fierce battle ensued. In the photographs we see people first with expressions of fear, followed by curiosity, then joy and pride as the Chinse gun down Japanese planes."
