On April 22, 1938, the 182nd Division of the Luhan Division of the Dian Army exchanged fire with the Japanese army at YuwangShan, which caused the isogu Division, which was known as the elite of the Japanese army in North China, to rush to the terrified Battle of Yuwangshan.
Because the Japanese Isoya Division took the lead in launching a surprise attack on Yuwang Mountain, and Lu Han's troops incorrectly estimated the main direction of the Japanese attack, the 182nd Division of the Dian Army suffered heavy losses under the Japanese onslaught.
Zhang Chong, then commander of the 184th Division, took the initiative to ask commander Lu Han for help, hoping that his 184th Division would take over the position of Yuwangshan, and before that, Zhang Chong had already seen through the Japanese army's surprise attack plan, so Lu Han attached great importance to Zhang Chong's suggestion.
However, Lu Han's Sixtieth Army had three divisions under its command, and in addition to the 182nd Division stationed at YuwangShan, Zhang Chong's 184th Division and Gao Yinhuai's 183rd Division both needed to defend the frontal positions at Taierzhuang.
Moreover, Gao Yinhuai's 183rd Division suffered heavy losses in the first round of Japanese raids, and Lu Han feared that once Zhang Chong took the 184th Division away, the Taierzhuang front would not be able to block the next round of Japanese attacks.
Zhang Chong said that before the Dian army was stationed to take over Taierzhuang, the Northeast Army's Yu Xuezhong Department was responsible for garrisoning Taierzhuang, and now that Yu Xuezhong's department has completed its rest, it is completely possible for the Northeast Army to assist in garrisoning Taierzhuang.
However, just when Zhang Chong was trying to persuade Lu Han, the 182nd Division stationed at Yuwang Mountain had been defeated by the Japanese army, and YuwangShan was also occupied by most of the Japanese army, zhang Chong did not dare to continue to delay, and immediately led his troops to Yuwangshan.
When Zhang Chong and his troops arrived at Yuwangshan, they found that the Japanese Isoya Division had concentrated almost all its main forces in the Yuwangshan area, and even used the "red wall tactic" in order to capture Yuwangshan.
The so-called "red wall tactic" is an artillery tactic, which simply means that the use of artillery fire to comprehensively cover a certain area can cause a devastating blow to the defenders' fortifications.
Zhang Chong knew that neither the 182nd Division nor his own 184th Division could face the Japanese heavy artillery group head-on, so Zhang Chong had no choice but to ask for help from the Commander's Headquarters of the Fifth Theater of the Nationalist Army.
In order to counter the heavy artillery units of the Japanese army, Bai Chongxi, who coordinated with bai Chongxi, who commanded the fifth theater of the Nationalist army, transferred all the artillery units of the nationalist army under his control to Yuwang Mountain, and Zhang Chong also had heavy firepower that could compete with the Japanese army.
After a fierce artillery battle, the two sides entered a stage of short-term contact, and most of the Dian troops under Zhang Chong's command were people who lived in the Yunnan-Guizhou Plateau for many years, and they had been shuttling between mountains since childhood, and they were extremely good at mountain combat.
Zhang Chong ordered that when the Japanese used heavy equipment such as mortars and heavy machine guns, everyone used climbing skills to hide on the rock wall and wait until the Japanese sent infantry to charge and then open fire to counterattack.
Under the command of Zhang Chong, the Dian army troops successfully scaled up the firepower superiority of the Japanese army, and the two sides soon entered an extremely fierce stage of hand-to-hand combat, and Zhang Chong ordered all those wounded behind them to be disposed of according to the front.
Under the onslaught of Zhang Chong's troops, the Japanese troops on Yuwang Mountain were gradually defeated and soon retreated to a position halfway up the mountain, while Zhang Chong's 184th Division also suffered heavy losses, and even the brigade commander was wounded in the attack.
At this time, the Japanese position at Yuwang Mountain had been compressed to the summit area, and Lu Han personally issued a general offensive order to Zhang Chong's 184th Division, demanding that Zhang Chong must recover the top of Yuwang Mountain from the Japanese at all costs.
Because Yuwang Mountain is located on the flank of Taierzhuang, and the top of Yuwang Mountain is the nearby commanding heights, occupying the top of Yuwang Mountain can overlook the entire Taierzhuang area, once the Japanese army set up artillery positions on the top of Yuwang Mountain, it can directly cut off the supply line of the Nationalist army.
For the importance of Yuwang Mountain, the Japanese army is also aware of it, in order to defend Yuwangshan, the commander of the Japanese army division, Isoya Rinsuke can be said to have searched the intestines and scraped the stomach, and even the smoke bombs used to cover the battle were used as conventional weapons.
Under the cover of the Japanese army's firepower at any cost, Zhang Chong's troops, which were already in the upward attack position, suffered heavy casualties, and under the mood of the Japanese army releasing a large number of smoke bombs, Zhang Chong's troops were difficult to distinguish the direction when attacking.
However, fortunately, the Japanese army was not familiar with mountain warfare, and the changeable mountain wind soon blew smoke above the Japanese position, and Zhang Chong ordered to attack the Japanese position at any cost of casualties when he saw the opportunity.
In the end, Zhang Chong's 184th Division successfully recovered the Position of Yuwangshan at the heavy cost of Yuan Qi's heavy injuries, and the Japanese army even called it the most courageous and warlike Nationalist army encountered after the outbreak of war.
