Tang Shengzhi
By December 9 Japan's forces had reached Nanking's last line of defense, the daunting Fukuo Line. At this point General Matsui had a "summons to surrender" drawn up which implored the Chinese to send military envoys to Nanking's Zhongshan Gate to discuss terms for the peaceful occupation of the city, and he then had a Mitsubishi Ki-21 scatter thousands of copies of the message over the city. On December 10 a group of Matsui's senior staff officers waited to see if the gate would be opened, but Tang Shengzhi had no intention of responding.
