Last time we spoke about the crossing of Nanjing’s Rubicon. By November 1, Shanghai had become a lost cause, the Chinese were forced to retreat. In the wake of this turmoil, the Japanese set their sights on Nanjing, keenly aware that its fall would spell disaster for Chiang Kai-Shek's government. Despite the desperate situation, guerrilla fighters began fortifying the city as civilians rallied to support the defense, preparing for the inevitable assault that loomed. However, political divisions plagued the Chinese leadership, with some generals advocating for abandoning the city. After intense discussions, it was decided that Nanjing would be a hill worth dying on, driven largely by propaganda needs. As November 12 approached, Japanese troops rapidly advanced west, capturing towns along the way and inflicting unimaginable brutality. On November 19, Yanagawa, a commander, took the initiative, decreeing that pursuing the retreating Chinese forces toward Nanjing was paramount.

As the Chinese troops fled westwards, at 7:00 am on November 19th, Yanagawa issued instructions to his troops in the field. “The enemy’s command system is in disarray, and a mood of defeat has descended over their entire army. They have lost the will to fight. We must not miss the opportunity to pursue the enemy to Nanjing.” The order went out to the 10th Army, sending, the 6th, 18th, and 114th Divisions west along the southern shore of Lake Tai, passing through Huzhou before turning right towards Nanjing. The Kunisaki Detachment, trained for rapid movement by water and land, was ordered east along the Yangtze River near Wuhu city and, if possible, cross the river to cut off the Chinese Army’s retreat from Nanjing. Yanagawa envisioned an operation unlike any other conducted by the Japanese Army in recent history. He believed this could not only end the war but also surpass previous victories, such as the defeat of tsarist Russia more than three decades earlier. Confident in a swift victory, he wrote in a follow-up message to his commanders, “The day is near when the banner of the Rising Sun will fly over Nanjing’s city wall.”

However, Yanagawa's order elicited panic in Tokyo once it became known. His superiors viewed it as an outrageous attempt to entirely change the war focus away from the north. They understood that taking Nanjing was primarily a political decision rather than a strategic one. There was still hopes of finding terms through the Germans to end the conflict, thus carving up more of China. The Japanese did not want to become bogged down in a real war. Major General Tada was particularly opposed to increasing efforts on the Shanghai front. He belonged to a faction that believed the best way to avoid a quagmire in China was to deliver a swift, decisive blow to the Chinese Army. This mindset had turned him into a major advocate for landing a strong force in Hangzhou Bay in early November. Nevertheless, he had initially resisted expanding operations to the Suzhou-Jiaxing line, only relenting on the condition that this line would not be crossed under any circumstances.

Tada’s immediate response was to halt the 10th Army’s offensive. Shimomura Sadamu, Ishiwara Kanji's hardline successor as chief of operations, strongly disagreed, arguing that field commanders should have the authority to make significant decisions. Undeterred, Tada insisted on restraining the field commanders, and at 6:00 pm on November 20th, the Army General Staff sent a cable to the Central China Area Army reprimanding them for advancing beyond Order No. 600, which had established the Suzhou-Jiaxing line. The response from the Central China Area Army arrived two days later whereupon the field commanders argued that Nanjing needed to be captured to bring the war to an early conclusion. To do otherwise, they argued, would provide the enemy with an opportunity to regain the will to fight. Moreover, the officers claimed that delaying the decisive battle would not sit well with the Japanese public, potentially jeopardizing national unity. On the same day it responded to Tokyo, the Central China Area Army instructed the 10th Army to proceed cautiously: “The pursuit to Nanjing is to be halted, although you may still send an advance force towards Huzhou. Each division is to select four or five battalions to pursue the enemy rapidly”. The remainder of the troops were instructed to advance towards Huzhou and prepare to join the pursuit “at any time.”

Meanwhile Chiang Kai-shek officially appointed Tang Shengzhi as the commandant of Nanjing’s garrison. Born in 1889, Tang embodied the era of officers leading China into war with Japan. They straddled the line between old and new China. During their youth, they lived in a society that had seen little change for centuries, where young men immersed themselves in 2,000-year-old classics to prepare for life. Like their ancestors across countless generations, they were governed by an emperor residing in a distant capital. Following the 1911 revolution, they embraced the new republic and received modern military training, Tang, for instance, at the esteemed Baoding Academy in northern China. Yet, they struggled to fully relinquish their traditional mindsets. These traditional beliefs often included a significant distrust of foreigners. Before his appointment as garrison commander, Tang had led the garrison’s operations section. During this time, Chiang Kai-shek suggested that he permit the German chief advisor, General Alexander von Falkenhausen, to attend staff meetings. Tang hesitated, expressing concern due to Falkenhausen’s past as a military official in Japan and the current alliance between Germany, Italy, and Japan. “That’s not good, is it?” he asked. Chiang reassured him that Falkenhausen was an experienced officer who remembered earlier loyalties despite political shifts in Berlin. “It’s all right,” Chiang insisted, “we can trust him.” Reluctantly, Tang acquiesced but never fully trusted the German officer. Tang also faced issues with morale. He was Hunanese, the majority of his troops were locals, many from Nanjing. Tang also suffered from many ongoing illnesses. While he put on a bravado face, its unlikely he expected to be able to defend the capital for very long.

On November 19th, the IJA 16th division and Shigeto Detachment conquered Changshu, a crucial point along the Wufu defense line, spanning from Fushan on the Yangtze to Suzhou and then to Wujiang sitting on the shores of Lake Tai. The fight for Changshu had surprised the Japanese. As they approached they ran into a network of interlocking cement pillboxes that had to be taken individually, resulting in heavy casualties. Frequently, when the Japanese believed they had finally destroyed a position and advanced, they were dismayed to discover that some defenders remained alive, continuing to fire at their flanks. Another obstacle facing them was Chinese artillery. During the night's capture of the city, the Japanese makeshift camps were hit relentlessly by bombardment. That same day further south, the IJA 9th division captured Suzhou , reporting to the press they did so without firing a single shot. General Matsui wrote in his diary “The enemy troops near Suzhou have completely lost their morale. Some soldiers are discarding their equipment and surrendering, while others flee westward in utter chaos. Our forces have not encountered the resistance we anticipated. So far, the Shanghai Expeditionary Force has achieved all its objectives. I am thrilled by this.”

In reality, this was mere propaganda. The IJA 9th Division actually had to overpower a series of Chinese pillboxes outside the city. Once they entered through the medieval walls, they faced the task of eliminating pockets of resistance one by one. According to Japanese sources, over 1,000 Chinese soldiers were killed during these clearing operations. The Japanese found a wealth of spoils in Suzhou. Among the booty were 100 artillery pieces and other military equipment. Historically known as one of China's wealthiest cities, Suzhou still contained an abundance of loot even after months of conflict. Many Japanese soldiers had their pockets filled with cigarette...
