candidates: The Japanese awaited an answer to their demand for surrender but no response was received from the Chinese by the deadline on December 10. General Matsui Iwane waited another hour before issuing the command to take Nanking by force. The Japanese army mounted its assault on the Nanking walls from multiple directions; the SEF’s 16th Division attacked three gates on the eastern side, the 6th Division of the 10A launched its offensive on the western walls, and the SEF’s 9th Division advanced into the area in-between. On December 12, under heavy artillery fire and aerial bombardment, General Tang Sheng-chi ordered his men to retreat. What followed was nothing short of chaos. Some Chinese soldiers stripped civilians of their clothing in a desperate attempt to blend in, and many others were shot by the Chinese supervisory unit as they tried to flee. On 13 December, the 6th and the 116th Divisions of the Japanese Army were the first to enter the city, facing little military resistance. Simultaneously, the 9th Division entered nearby Guanghua Gate, and the 16th Division entered the Zhongshan and Taiping gates. That same afternoon, two small Japanese Navy fleets arrived on both sides of the Yangtze River.
