On the left flank, the 53rd Army lurked on the Longchuan River. Heavy rain fell all night, and in the early morning of July 2, the riverside was filled with dense fog, and there was no figure on the opposite side, which was a great opportunity for the commander of the 53rd Army, Zhou Jun, who decided to take advantage of the lack of a figure on the opposite side, and attacked at the same time on three roads, and hit the Japanese army by surprise.

Taking advantage of the heavy rain and dense fog, the 116th Regiment of the 348th Division of the main force quietly rushed to Feifeng Mountain. The fog concealed the whereabouts of the attacking troops, and the garrison Japanese troops were really defenseless, and only hurriedly responded to the battle when the guns rang out around them, and they were dizzy, and the Japanese army soon lost Feifeng Mountain.

This is the most crisp and joyful battle in the first battle of Tengchong periphery! It only took three hours for the Japanese army to lose the eastern barrier of Tengchong City.

The various units under the command of Commander Zhou fought bravely, and the 347th Regiment of the 116th Division quickly advanced to Hetou Village and Laodamen; The main force of the division captured the 5830 heights in one fell swoop; The 388th Regiment of the 130th Division occupied Yubi, Wuyi, and Huangpo, and advanced to the south of Feifeng Mountain, while the 390th Regiment advanced to the east side of Longjiang Bridge; The general headquarters of the division also advanced with the regiment to the Longjiang Bridge.

The troops on the left flank were victorious, and the right flank did not let the vanguard.

The 592nd Regiment of the 198th Division of the 54th Army then used the means of sneaking up on the enemy camp and took advantage of the night to raid the Niangniang Temple in the north of Tengchong City and capture Dongku.

In the face of a large Japanese brigade defending the enemy, the 2nd Regiment attacked for several days, but still failed to break through the enemy's defensive position, and the sound of guns and cannons on the battlefield and the sound of shouting and killing continued to night, although Peng Gang desperately fought for the key place in the north of Tengchong City, and the troops who charged many times were all beaten back by the Japanese army, and they were never able to set foot on the 5138 heights.

Seeing the loss of Feifeng Mountain, Zangzhong Kangmei was busy secretly mobilizing troops to strengthen the front line in the suburbs.

In the middle of the night, a small squad of the Japanese army quietly slipped out of the north of Tengchong City and went straight to Baofeng Mountain, trying to attack the 2nd Pre-2 Regiment that was fighting fiercely from the flank. The sneak attack is a trick used by the devils, but even if it is used, it still has not been taken seriously by the Chinese soldiers, so the success rate of the sneak attack is quite high. The sneak attack organized this time was indeed a ruthless move, and if it succeeded, Commander Peng's troops would be vulnerable to the enemy and would be difficult to deal with. This group of Japanese troops traveled according to the usual road, until they touched Dong Ku, and then they did not know that Dong Ku had been taken by our 592 regiment at this time, and the unlucky Japanese army, this sneak attack was not so lucky, and it happened to run into the muzzle of the expeditionary force, and was successfully intercepted by our 592 regiment.

The worries of the 2nd Regiment were finally relieved, so that they were more able to launch a more fierce offensive against Baofeng Mountain with all their strength.

Unexpectedly, after the Japanese army that failed to succeed in the sneak attack was repelled by the 592nd Regiment, they fled to Laocaopo, and the two stubborn enemies merged into one, taking advantage of the danger to hold the 5138 heights of Laocaopo. This time, the pre-2 regiment has encountered a strong enemy.

Commander Huo immediately ordered the 198th Division on the north bank of the Daying River to work together with the 2nd Regiment and the 36th Division to work together and cooperate closely to take the 5138 Heights.

The artillery once again bombarded the old grass slope, and after two days of fierce fighting, on July 5, the 2nd Pre-regiment finally occupied the 5138 heights.

Commander Huo's first battle on the periphery of Tengchong was much smoother than attacking Gaoligong Mountain from above.

By July 7, the main force of the 36th Division had captured Guanyintang and approached Tengchong from west to north; The main force of the 198th Division had repelled the Japanese troops at Dingjiapu and Hejiazhai, and approached Tengchong from the east; The 116th and 130th Divisions captured Shangmengbianlian, Luohanchong, Nijiapu, Manjinyi and other places in successive days, cutting off the road from Tengchong to Longling, and at the same time approaching Tengchong from the southeast.

The 20th Army had formed a three-sided siege on Tengchong. Taking advantage of the victory, the troops pursued forward, constantly approaching Tengchong City, and the encirclement of the Tengyue garrison was gradually narrowing.

Laifeng Mountain, one of the peaks of the remaining veins of Gaoligong Mountain, the north side is next to the Daying River, the south is swooping to the city, it is located on the ancient post road leading to Myanmar, guarding the border and choking the city, and the strategic position is very prominent.

The mountain is composed of 5 beacon-shaped peaks, the main peak is Beacon Mountain, its left is Elephant Trunk Mountain, right is Yingpan Mountain, climb to the top of the mountain, stand above the top of Tengchong Ancient City nearly 150, the field of vision is broad, the panorama of the ancient city is in full view, Da Dong, and Shun are all in the present.

Coming to Fengshan is indeed a natural barrier for Tengchong City. Like the Songshan fortifications that were built, the Tengyue garrison captain Kurashige Yasumi had built Laifengshan into a fortress complex. With the main peak as the center, the five peaks guard each other, forming a firepower network that can support each other. In order to clear the range, Kurashige Yasumi cut down all the vegetation on the mountain, and the lush green forest was gone, and from a distance, there was only a bald mountain, not a single grass or tree, and the smooth soil slope was all exposed to the crossfire network at a glance. The moats between the fortresses are connected, the tunnels between the mountains are connected, and there is also a secret passage leading directly to Tengchong City from this mountain. Very well conceived.

Coming to Fengshan through this creation has become Tengchong's armor.

No wonder later others had poems as proof.

Tengchong Fortress counts as a phoenix,

Elephant trunk camp left and right arches.

Writing forms a steel barrier,

Zhuge can't show supernatural powers!

Commander Huo doesn't have Zhuge Liang's ability, what kind of magic trick will he use to cross this mountain?

On July 6, on the right flank of the 20th Army, the 2nd Reserve Division of the 54th Army continued to attack Laifengshan after capturing the 5138 heights. After a fierce battle all day, he did not gnaw down a single corner of Fengshan.

On the 7th, Division Commander Gu readjusted the deployment, and only used one part to attack Bashoguan head-on, in order to confuse the Japanese army, and the main force quietly detoured back to the side of Laifeng Mountain, and successively captured Heshun Township, Longguangtai, Laocaopo, and Pilu Temple on the periphery of Laifeng Mountain, and finally approached Laifeng Mountain.

This division commander Gu, who graduated from the 4th class of Huangpu and the 8th class of the special class of Lu University, fought guerrilla warfare behind enemy lines in western Yunnan two years ago, and has quite a lot of experience in flexible combat. His deployment was: The 4th Regiment started to attack from Heshun Township behind the side of Laifeng Mountain, captured Wenbi Tower and Yingpanpo in the southwest, and at the same time attacked Elephant Trunk and Wenbi Slope in the northwest with the 5th Regiment, with the 6th Regiment as the reserve, and after the 4th and 5th regiments succeeded in attacking, they would attack the main peak of Laifeng Mountain together with the 2nd Regiment.

With several times the enemy's superior forces, the Japanese troops that surrounded each hill were divided and annihilated. Of course, this strategic deployment is well-planned and feasible. It should be said that this is much more flexible than the deployment of Commander He's attack on Songshan. Of course, Laifengshan is not as big as Matsuyama, not as dangerous as Matsuyama, Sakaguchi will build Matsuyama as a "Maginot Line", and it has its own solidity, however, this Tibetan heavy Yasumi also operates Laifengshan as the protector of Tengchong, and the attack is still very difficult.

The wooded Laifeng Mountain had no cover, like a sleek pyramid, and the attacking troops were all exposed to the guns of the Japanese army.

Because the expeditionary force did not know anything about the layout of the Japanese army's fortifications, it was not clear where the pillboxes and tunnels were buried, and they did not hear the gunfire of the Japanese army, so they could not touch the reality of the Japanese army at all, let alone know the firepower of the Japanese army. The 4th and 5th regiments of Gu Division Commander rushed up the bare slope with courage, intending to attack the enemy's position with overwhelming superiority before the Japanese guns fired. Unexpectedly, after attacking the mid-mountain and entering the range of the Japanese army, the enemy's densely woven fire net tightly covered the 4th and 5th regiments, and the 4th and 5th regiments were exposed on the hillside without any cover......
