After the failure of the "Battle of Bengmiao", Sakakou repeatedly mobilized his troops in a vain attempt to break through the encirclement of Longling by the 11th Group Army of the Expeditionary Force, but he did not achieve his goal, on the contrary, Song Xilian's southern flank successfully conquered Xiangda, which directly threatened the Mangshi Laolai of the 56th Division.

For this reason, the commander of the 33rd Army of the Japanese Army, Honda Masasa, was very irritable. His northern front, Myitkyina, was also difficult to hold under the attack of the Chinese army stationed in India, and the eastern front, the western Yunnan battlefield was in full urgency, Longling, Songshan, and Tengyue Daquan were surrounded by Wei Lihuang's army, and the situation became more and more unfavorable for him.

Honda Masato was so anxious that he urged the Japanese base camp to increase troops every day. In mid-August, the additional recruits brought in from Japan reported to the 56th Division one after another, so that there were more than 6,000 Japanese troops in the Mangshi area. At this time, Sakaguchi had completed the suggestions for various strongholds around Mangshi and the reserve of military supplies, and the Japanese army base camp was more confident.

The time has finally come to carry out the "one-phase operation".

With a wave of his saber, Honda Masaki advanced the 33rd Army's combat command post from Xinwei to Mangshi, and began his "Interrupted Phase 1 Operation". The main content of its battle plan was as follows: the 2nd Division and the 56th Division fought together, attacked from both sides, quickly broke through Longling, and then advanced to the line of the Nu River, rescued the Lameng garrison, and then rescued the Tengyue and Pingga garrisons.

This plan was completely disrupted by Song Xilian. The 11th Army's offensive on Longling was tighter than one time, Xiaobao Zhongzuo was in a hurry again, Longling couldn't hold it, Honda Masashi did not dare to delay, he wanted to seize Song Xilian's strong offensive against Longling before the 56th Division in western Yunnan to rescue Longling.

Honda Masako had long explained to his generals that the focus of the "Breaking the Battle Plan" was in western Yunnan, and the focus of the defense of western Yunnan was in Longling. He kept asking Xiaobao to persevere, but when Xiaobao couldn't support it, he still had to hold on.

At this time, the 2nd Division, which was newly assigned to the 33rd Army, had withdrawn from the Hukang River Valley, and in order to seize time, Honda Masasai could not wait for it to hand over to the 18th Division in the area, and ordered the 2nd Division to immediately advance directly from Nankan to Mangshi, as a follow-up to the 56th Division, to prepare for the Longling Battle. The 56th Division quickly entered the "first phase of the operation".

The vanguard of the Japanese army moved quickly and moved quietly.

The 2,000 Japanese troops of the 56th Division set out from Shafang, avoided the Mukang and Hongyan mountain passes where they had been badly damaged, and bypassed from Mangshi. This line is the weak point of the 7th Army of the Expeditionary Force.

On August 25, a large group of Japanese troops appeared in Xiangluantang, southwest of Longling, and engaged the search company of the 71st Army. After the search and firing warnings, the Japanese army took advantage of the situation to quickly insert into Beiyin Mountain, Fangmaqiao, Yejiazhai, Nantianmen and other places east of Xiangluotang.

On the Longling Mangshi line, Fangmaqiao, Nantianmen, and Zhangjinshan choke the Manglong Highway, which is an important highland for Pingwei Longling, and the Japanese army is attacking with all its might, trying to open up the Manglong Highway, so that the large army can drive into Longling.

Song Xilian hurriedly drew troops from the New 39th Division and the Honor 1st Division and rushed to a bowl of water, Beiyin Mountain, and Nantianmen to block the Japanese army.

At this time, part of the Japanese army had already entered the Fangma Bridge, and the Fangma Bridge was even more critical.

The 227th Regiment of the 76th Division stationed in Shantouzhai quickly responded, and under the leadership of the regiment commander Yang Qingfu, attacked from Shantouzhai to Fangmaqiao, but unexpectedly could not stop the fierce artillery offensive of the Japanese army, so it had to retreat to Tongguoyuan, intending to block the attack there. Fortunately, the 1st Battalion of the 25th Regiment of the 9th Division arrived, and the two units worked together to block the Japanese attack.

Xiaobao Zhongzuo, the captain of the Longling garrison who was in a predicament, learned that Mangshi was increasing troops to Longling, so he immediately drilled out of the dark fort and launched a counterattack against the 71st Army from Wenbi Slope, Fengjia Slope, and Mast Slope. Chen Mingren's troops were attacked on both sides, and the battle in Longling was tense again.

A Japanese army has entered Longling from a bowl of water.

The situation is dire.

Song Xilian had no choice but to order the "God of War" to lead the troops to the front line of Nantianmen, and commanded the search battalion of the 71st Army and the infantry regiment of the Yunnan-Kang-Burma Special Guerrilla Regiment to hold the position and block the enemy together.

The line of Fangma Bridge, Nantianmen and Zhangjinshan is dangerous everywhere, especially the most dangerous in Nantianmen. Standing on the high cliff of Nantianmen and peeking down, the Manglong Highway passes through the mountains like a thin line, and holding these hills can prevent the Japanese army from advancing north.

After the 39th Division arrived at Nantianmen, it immediately rushed to repair the fortifications on the mountain, but before the trenches were built, the Japanese army crossed the Fangma Bridge and attacked Nantianmen.

The Japanese army occupied western Yunnan for more than two years, and was very familiar with the terrain in this area, and the cunning Japanese army avoided a frontal attack, but went around to the Dapotou on the left side of Nantianmen, preemptively occupied the Dapotou Heights, set up light and heavy machine guns, and directly strafed the Nantianmen guards with a densely woven firepower network, and the 117th Regiment of the New 39th Division, which was rushing to repair the fortifications, immediately organized a response, but unexpectedly, the gunfire on the right side was urgent, and the other Japanese army had made a detour to occupy the right flank of Nantianmen.

The 3rd Battalion of the 117th Regiment, which was guarding the Nantianmen, was desperately resisting.

Rumble! ......

The earth-shattering sound of artillery rang out, and countless flashes lit up on the first line position of the 3rd Battalion of the 117th Regiment, shells poured down like raindrops, and the earth set off a terrible red wave.

Tons of shells poured down tons of artillery on the defenders' positions, which were washed by the torrent of steel, and the trenches and various fortifications could not reach the bombardment of large-caliber naval guns, and were razed to the ground with the roar of the ground shaking and shaking.

The terrifying shock wave and the violent explosion had made the officers on the positions of the 3rd Battalion of the 117th Regiment give up their roars, and now the situation is only a matter of luck, and whoever survives is completely up to luck. The recruits of the 3rd Battalion of the 117th Regiment were pale at the moment, so frightened that they couldn't hold their guns steadily, and some of the recruits lay directly in the muddy water of the trenches, but they still couldn't save themselves, and they were directly shocked into the air by the shock wave of the large-caliber naval guns, and when they fell on the trenches, the fragile internal organs of the human body had been shattered......

Zhao Dingjun, the commander of the 3rd battalion, looked at the recruits who were running in a panic, and sighed in his heart, the soldiers who had not seen the cruel situation on the battlefield were still a little worse after all, and they were like the difference between children and adults compared to a real soldier.

"Perhaps only in this torrent of steel, after the baptism of blood and fire, will these recruits truly transform and grow. It's just that how much more will survive? Maybe they will all die on this position. Zhao Dingjun squatted in the trench and thought.

The salvo fire of the devil's naval artillery began to extend, and the shells had fallen on the second-line positions and those roads that might rush to support, but the devil's artillery squadron was still bombarding the first-line positions with field artillery, mountain artillery, and infantry.
