When the Japanese troops arrived at the outskirts of Nanjing in early Dec, Tang realized that his defenses, untrained and demoralized to the point that many were simply abandoning their posts, had no chance of winning. Chiang maintained that Tang, previously enthusiastic but now realizing the impossibility of winning, should continue to stage the defense. On 7 Dec, the Japanese Army announced internally that soldiers who commit "illegal acts" and "dishonor the Japanese Army" during the conquest of Nanjing would be severely punished. Early on 9 Dec, the Japanese Army arrived at the Nanjing's city wall, and demanded surrender within the following 24 hours. No Chinese envoy appeared, and at 1300 hours, General Iwane Matsui and Lieutenant General Prince Asaka (Yasuhiko) concluded that the Chinese were not interested in negotiating, and gave the order for attack.
