Battle of Xinkou
In late September 1937, Japanese commander Itagaki Seishiro ordered the Fifth Division and Chahar Expeditionary Force to begin their assault on the Chinese defense line along the inner Great Wall in Shanxi. The Japanese forces had already occupied Datong after battles at Nankou and were marching westwards from Hebei. They took control of towns including Guanglin, Linzhou, and Hongyuan in northwest Shanxi before reaching this critical point. Chinese Commander Yan Xishan of the 2nd War Zone ordered his troops to retreat and establish a new defensive position at Niangziguan and Pingxingguan. Even after the Eighth Route Army led by Lin Biao successfully ambushed Japanese forces at the Battle of Pingxingguan, heavy casualties under Japanese artillery and tank assaults forced Chinese defenders to withdraw further toward Wutaishan.
On the 1st of October 1937, the military commission of the Chinese Nationalist government ordered the 14th Group Army commanded by Wei Lihuang to fight the Japanese at Xinkou. This location was flanked by Wutaishan and Yunzhonshan mountains, creating a natural gateway to Taiyuan, the capital of Shanxi province. The 14th Group Army organized a frontal defense while Yan Xishan's eight armies supported them. On the right flank, the 18th Group Army without the 120th division, along with the 101st division, 73rd division, and newly formed 2nd Division, defended along the Sutou River's south bank under Zhu De's command. One division was sent to harass the enemy's left flank from behind. The 6th Group Army comprised two divisions and one brigade on the left flank, including the 120th division commanded by Yang Aiyuan concentrating forces at Heiyu and Yangfangkou. Another division harassed the right flank from the rear. Reserve forces included the 34th and 35th Armies under Fu Zuoyi controlling the Dingxiang and Xinxian area.
On October 13, Itagaki Seishiro led 50,000 Japanese troops in a major assault against Xinkou. The 5th Division attacked Nanhuaihua on the left wing while the 15th Brigade focused on Dabaishui on the right wing. The 2nd Brigade remained in the rear defending the inner Great Wall. Japanese forces deployed over 30 airplanes, more than 40 heavy artillery pieces, and over 50 tanks to support their infantry assaults. Chinese central defense forces used favorable terrain to resist despite lacking firepower. On October 16, Chinese defenders launched a counter-attack to take high grounds at Nanhuahua during which General Hao Mengling of the 9th Army became the first Chinese army general killed in action during the Second Sino-Japanese War. Despite his death, commanders Chen Zhangjie of the 61st Army and Wang Jingguo of the 19th Army continued leading defenses successfully. By this time, Japanese forces had suffered close to 20,000 casualties without making significant progress on their assault of Xinkou.
The military commission ordered troops of the 1st War Zone to relocate and set up defenses at Niangziguan with Huang Shaohong assigned as commander for the operation. The 17th and 30th Divisions defended the center while the 3rd Army positioned at the right wing and 14th Group Army covered the left wing. On October 11, the 20th division of the Japanese army captured Jingxing. Japanese forces used only some troops to attack Niangziguan directly while their main force marched around and captured Jiuguan. With defenders effectively surrounded, Yan Xishan ordered the 26th Army led by Sun Lianzhong from northern Shanxi to move to Niangziguan and conduct counter-attacks. This effort failed to retake Jingxing as planned. On October 21, the 20th division was reinforced by the 109th division and continued attacking Niangziguan from the south with support from Japanese bombers and fighters. On October 26, four Japanese commando battalions broke through Chinese 3rd Army defenses at Ceyuzhen and breached the Niangziguan defense line.
During the battle, the Communists' Eighth Route Army executed several guerrilla attacks in the Japanese rear at locations including Lingqiu, Guangling, Weixian, Pingxingguan, Ningwu, and Yanmenguan. On the evening of October 19, the 769th Regiment of the 120th Division attacked Yangmingbao airbase and successfully destroyed 24 Japanese airplanes on the ground. These operations disrupted Japanese supply lines and communications while drawing attention away from the main defensive positions. The destruction of aircraft represented a significant tactical victory despite the overall strategic situation remaining dire for Chinese forces. Communist units maintained pressure on Japanese flanks throughout the campaign, forcing them to divide their resources between front-line combat and rear-area security.
General Li Mo'an later stated that the only weapon Chinese infantry had against Japanese tanks was Molotov cocktails. Many defenders on the left flank were simply run over by tanks due to lack of anti-tank capabilities. The ill-equipped 8th route army suffered particularly severe disadvantages compared to Japanese mechanized superiority. Despite fighting bravely on a united front, Chinese forces faced a large shortage of firepower throughout the engagement. This equipment gap meant that even when holding favorable terrain, Chinese troops could not effectively stop advancing armored units without specialized weapons or heavy artillery support.
The battle marked the first large-scale cooperation between provincial army forces under Yan Xishan, Chinese Communists led by the Eighth Route Army, and Chiang Kai-shek's Central Army through the 14th Group Army during the Second Sino-Japanese War. Although Chinese defenders fought bravely, they ultimately lost control of northern China after this battle and subsequent fighting around Taiyuan. Resistance was reduced to minor guerrilla attacks behind enemy lines following these defeats. However, because communists and nationalists cooperated well while inflicting serious losses on Japan, many Chinese citizens were inspired to join the fight against invaders. Officers like Jiang Yuzhen became martyrs whose sacrifice motivated further resistance efforts. Chinese forces paid the price of 100,000 troops dead, injured, or missing but managed to kill approximately 20,000 Japanese troops, wound thousands more, destroy dozens of tanks, and eliminate more than 24 aircraft in what set a record high for damage inflicted to Japanese forces in a single battle in Northern China.
