Nanking fell on December 13, for the camera crew the day before they would enter Nanking, and according to the journal of production clerk Akiyoshi Yonezawa they had heard stories about attacks by Chinese stragglers and feared that their equipment would get robbed. His journal then notes that they entered Nanking on the 14th as mopping-up operations were being undertaken in the northern half of the city and that they heard bursts of gunfire which they assumed to be the Japanese Army battling remnants of the Chinese Army. Filming inside Nanking started on the 15th and even then mopping-up operations were still taking place in the vicinity of Yijiang Gate which they visited that day. On the 16th they shot footage of the foothills of Purple Mountain, the suburban recreational garden containing Sun Yat-sen Mausoleum, and a nearby concert hall where dogs were wanderingly freely. On the 17th they filmed the Japanese Army's victory parade through Nanking, the footage of which was immediately airlifted to Japan for presentation before Emperor Hirohito. According to Yonezawa's journal, the film crew witnessed the plight of Nanking's refugees to preserve the story in images, but also noted the kindness with which the refugees were treated by the Japanese Army. The journal also notes that the camera crew filmed the construction of water supply facilities and the provision of medical treatment to Chinese POWs.
