From Nanjing 1937: Battle for a Doomed City, by Peter Harmsen (Casemate, 2015), Kindle Loc. 849-863:
Towns and cities west of Shanghai fell in rapid succession, and everywhere the same pattern repeated itself: quick conquest was followed by comprehensive destruction. In some areas, it was a repetition of the most sinister parts of history. Jiading, a county seat with about 30,000 residents, was known to students of history for its refusal in 1645 to bow to China’s new rulers, Manchu armies from beyond the empire’s northeastern borders. The invaders had imposed a lengthy siege, and once the city fell, they massacred all the defenders. A centuries-old pagoda had been looking down on the carnage then, and in 1937 it was still standing as new blood was being spilled.
This time the conquerors were from the 101st Japanese Infantry Division. They were reservists, several years older than the average soldier in divisions such as the 3rd or the nth [sic; 9th?]. Just months earlier they had been farmers and accountants, and many were fathers of small children. When they took Jiading on November 13, after shelling had leveled one third of the city, they set about killing almost everyone in sight, be they man, woman or child. During the battle and in the weeks afterwards, they were responsible for the deaths of more than 8,000 residents in the city and in the surrounding countryside.
“A city of death,” was how a Japanese visitor described Jiading shortly after the battle, as he encountered “a mysteriously silent world in which the only sound was the tap of our own footsteps.” War had wiped the city clean of most traces of humanity, reducing the few remaining residents to shadowy ghost-like creatures. “All we saw,” the Japanese visitor said, “was the occasional doddering elder crawling out from one of the collapsed hovels and going back in again.”
