Beginning in August 1937 the Japanese Imperial Army initiated an aerial assault of the Chinese capital city of Nanjing (Nanking). In response to this assault, thousands of Chinese able to flee left the city while the elderly, sick, and poor remained behind. Many that left continued to actively fight the Japanese. Others actively resisted. In Nanjing, like in other cities throughout China in the late nineteenth and early twentieth century, Western merchants, missionaries, physicians, and educators had settled seeking economic opportunities or fulfilling religious or professional aspirations. Hundreds of these Westerners considered Nanjing initially their home.
