In December 1937, the Japanese Imperial Army invaded Nanking in China and what transpired over the following six weeks became known as the Nanking Massacre. Many people have offered their accounts of what happened during this period, and this particular collection from the Yale Divinity School Library offers the perspectives recorded by a number of Westerners who remained in Nanking after the Japanese invasion. For the most part, these Westerners were businessmen and missionaries and their letters and photographs are available on this site. Visitors can click on their names as they wish or also look through the "Documents" list to peruse each document at their leisure. Additionally, the site also includes several dozen photographs which document everything from refugee camps to military parades.
