He Yingqin
With Shanghai under their control, the NRA turned its attention to Nanjing. He Yingqin advanced from the south-east, whilst Cheng Qian came from the south-west. Zhang Zongchang ordered his Shandong Army to withdraw from Nanjing on 23 March, leaving the city undefended. Cheng arrived on the next day, entering the city with no resistance. Almost immediately after arrival of the NRA, mass anti-foreigner riots broke out in the city, in an event that came to be known as the Nanjing Incident. British and American naval forces were sent to evacuate their respective citizens, resulting in a naval bombardment that left the city burning and at least forty people dead. He's forces arrived on 25 March, and on the next day, Cheng and He were finally able to put an end to the violence.
