The Japanese Army had pushed quickly through China after capturing Shanghai in November 1937. By early December, it was on the outskirts of Nanjing. The speed of the army's advance was likely due to commanders allowing looting and rape along the way. As the Japanese approached, the Chinese army withdrew the bulk of its forces since Nanjing was not a defensible position. The civilian government of Nanjing fled, leaving the city under the de facto control of German citizen John Rabe, who had founded the International Committee for the Nanking Safety Zone. On December 5, Prince Yasuhiko Asaka was installed as Japanese commander in the campaign. Whether Asaka ordered the Rape, or simply stood by as it happened, is disputed, but he took no action to stop the carnage.
