Since Zhennan Pass was in the hands of Da Ming at this time, Huang Zhiting's wolf soldiers could save the big problem of attacking Zhennan Pass, but since Zhennan Pass was so important, how could Annan have no defense?

In the distance of only ** miles south of Zhennan Pass, there is Tongdeng Fort of Annam, and the role of Tongdeng Fort is undoubtedly corresponding to Zhennan Pass, and the two sides form a confrontation here.

However, due to the surrender of the Mo Dynasty to the Ming Dynasty, the superficial relationship with the Ming Dynasty has been quite good, coupled with the southward movement of the Mo Dynasty's army, the defenders of Tongdengbao have been greatly reduced from four or five thousand at the peak to less than a thousand.

The Guinan wolf soldiers commanded by Huang Zhiting were named the East Route Army in this battle sequence, and the East Route Army did not spread flags all over the sky like the usual "Celestial Empire Army" and swaggered into Zhennan Pass. Instead, they quietly went south, not only did not fly the flag, but even turned into four strands, detoured from different roads, and arrived at Zhennanguan at night.

After resting for most of the night, Huang Zhiting's troops suddenly attacked in the early morning and marched to kill Tongdeng Fort.

Because it was too close, the Mo army of Tongdengbao was defenseless, and only had time to hurriedly close the fort gate, and the garrison in the fort had not all rushed to their own positions, and the gate of Tongdengbao was ordered by the bold Yellow Tiger to shoot at close range, and ten Jimao one-type guns were under the cover of wolf soldiers, and the fort gate was damaged in less than half an hour.

Huang Hu asked for an immediate siege, and Huang Zhiting agreed without saying a word. So the artillery retreated to rest, and the Huang wolf soldiers fought a bloody battle with the Mo army who finally reacted at the city gate, and successfully entered the fort. The defenders of Tongdeng Fort had already lit a beacon fire, and at this time, seeing that Tongdeng was no longer defending, the defender ordered a retreat, and he only led dozens of cronies to withdraw first.

In less than two hours, Tongdenburg, which had been emphasized several times by Gao Shipra before the war, changed hands. Since this battle was won by the main force of Siming Mansion and the artillery of the Gao family, the Tusi of Guinan no longer had any doubts about Huang Zhiting, and asked for battle one after another, asking for something to be done in the battle of Langshan.

Lang Son is about 30 li south of Dong Deng, and there are Kuma Mountain, Kukhao Mountain and two highlands in the northern periphery, Bawai Mountain in the northeast periphery, and Kodang Mountain in the eastern periphery.

These highlands have steep slopes, deep grass and dense forests, and the Mozambican army has long been densely packed with arrow towers on various highlands many years ago, guarding the main communication arteries, and becoming the main barrier to protect Lang Son. In order to attack Lang Son, these outlying strongholds must first be cleared.

After the enemy at Dong Deng was annihilated, the Lang Son Mo army, which had already learned the news from the beacon fire, hurriedly reduced its forces and adjusted its deployment.

The Mozambican army placed a force of about 500 people on both sides of the official road from Guo Zhu to Lang Son, and deployed defenses along the areas of Guo Zhu, Nahe and Nanliu; About 1,500 men were stationed on the two heights on the northeast side of Lang Son and on the front line of Ba Wai Mountain; About 300 people were placed in the Samcheong-dong area on the west side of Lang Mountain; More than 1,000 people were placed on the east and west sides of Lang Son on the south bank of the Qiqiao River; More than 5,000 Mohamo troops mainly defended the city of Lang Son.

In addition, after the beacon fire was lit in Lang Son Fortress, about 1,000 defenders of Zhiling County southwest of Lang Son rushed north to support Lang Son. On the second day, under the order of the Lang Son guard, this Mo army did not even enter the city, but moved to the west and south sides of Kuoma Mountain north of Lang Mountain, and divided its troops to guard the long heights southwest of Kunlai, the first line of Baihe, and the first line of Kuoma Mountain, Guan Hu, Nanliu and Shuixi.

Another Mozambican garrison, which had withdrawn from the mountains on the eastern border, advanced to the area of Chira and Yufei on the north bank of the Qiqiao River to help defend the city of Lang Son.

After Huang Zhiting took Tongdeng that day, the reason why she did not continue to go south to Langshan was that Langshan was thirty miles away from Tongdeng, and if she rushed that day, she would not be able to attack the city at night, and she was a little worried about whether the artillery of the Gao family could support continuous combat in one day, so she chose to rest for the night.

On the second day, Huang Zhiting's main force of the Eastern Route Army left only more than 1,000 people, responsible for guarding Tongdeng Fort and repairing the city gate as soon as possible.

In view of the fact that the Mozambican army in the Lang Son area was concentrated, the troops were relatively large, the defense line was strong, and the surrounding strongholds were all in the hands of the Mozambican army, which could support each other at any time, Huang Zhiting decided to first seize the peripheral points, creating a siege of Lang Son, and then take Lang Son in one fell swoop, so as not to create a situation in which the main force would be harassed in all directions as soon as it hit Lang Son.

This time, Huang Zhiting did not take credit, and pressed down his "descendants" Siming Mansion and Siming Prefecture wolf soldiers, and served as the general reserve in the direction of Langshan. This battle will be mainly left to other toasts.

After this period of movement between the two sides, in fact, in Lang Son, the Eastern Route Army is equivalent to facing about 13,000 or so Mo troops with a strength of more than 20,000 troops, although it does not seem to be a grand scale, but because the battlefield is only in this small area around Lang Son, the deployment of troops has been very close.

The main forces of the northern front of both sides focused on Lang Son, which was a real decisive battle, and it could even be said that the victory or defeat of the northern front was all in this battle.

Huang Zhiting was not in a hurry, in addition to sending all the Tusi wolf soldiers to clean up the surrounding strongholds, the Eastern Route Army organized the whole army into two echelons, camped about ten miles north of Lang Son, repaired again overnight and waited for the results of cleaning up the outer strongholds, and prepared to launch an attack from the north and east sides of Lang Son with the main force tomorrow.

In the early morning of the next day, it was drizzling and foggy in the area from Dong Deng to Lang Son, and there was a white expanse everywhere. At two o'clock, the Gaojia artillery of the Eastern Route Army carried out several rounds of artillery fire, mainly suppressing and destroying the Kuma Mountain position in front of Lang Mountain, the watchtowers of the Mozambican army in Bo New, Bo Mou, and Baga. At three o'clock, the artillery continued to advance under the cover of the wolf soldiers, and the artillery fire also extended forward at the same time. The wolf soldiers of the first echelon of the Eastern Route Army, including Siling Prefecture, Pingxiang Prefecture and Taiping Prefecture, began to launch a fierce attack on Langshan.

Nearly 3,000 wolf soldiers from the Siling Prefecture launched an assault on Lang Son from the front, and moved south along the high ground with the main force, forming a pincer offensive to launch a fierce attack on Kuma Mountain, opening the gateway to Lang Mountain.

There are about 2,000 wolf soldiers under the Pingxiang Prefecture Division, attacking and destroying the enemy in the area of Napai and Guo Zhushan; After that, he continued to advance on the left flank, captured Baro and Nahe, and cooperated with the Siling Prefecture to attack Kuma Mountain.

The wolf soldiers of Taiping Prefecture sneaked up and raided, occupying the unnamed high ground on the north side of Tanlong and waiting for the opportunity. After the two wolf soldiers of Siling Prefecture and Pingxiang Prefecture launched an offensive against Kuma Mountain, they suddenly joined the battle from the area east of this unnamed high ground south of Kuma Mountain, and developed an attack on the northern urban area of Lang Son.

After the general offensive began, the offensive of the Siling Prefecture on the right flank was amazing, and it only took half an hour to attack Kuma Mountain, beating the Mo army there until it collapsed and fled. At the same time, the surprise attack launched by the wolf soldiers of the Taiping Prefecture from the east side of the nameless heights also broke through the defense of the Mo army and continued to penetrate in depth.

On the front of their offensive, the Mozambican army was stationed on several high ground near Nonen, Bonu, Bomou and Nalai, blocking the advance of Huang's Eastern Route Army with crossfire from muskets, crossbows and a small number of earthen cannons.

The wolf soldiers of Siling Prefecture and Taiping Prefecture were hindered because they fought one game first, and the subsequent attacks were not as fierce as before.

After Huang Zhiting learned the news, he decisively sent most of the Gao family's light artillery troops, and the Gao family's artillery quickly opened fire and violently suppressed the Mo army on several high grounds. In fact, the terrain of this position is relatively complicated, and the artillery itself did not achieve much damage, but the Gaojia light artillery could fire continuously, which made the Mo army at a loss and frightened, and the defensive effect was greatly reduced.

The wolf soldiers of Siling Prefecture concentrated their elite and quickly marched forward, launched an attack again, and fought repeatedly and fiercely with the Mo army in various positions, and successively captured Nonen, Boniu, Bomou, the nameless heights on the east side of Nalai, and the nameless heights on the north side of Nalai. The battle lasted until noon, and finally broke the defense of the Mo army on this line, annihilating more than 400 enemies, and the rest of the Mo army fled, looking at the direction should be to retreat to Lang Son City.

However, the Mozambican army still held on to the unnamed heights on the south side of Nalai and the unnamed heights on the west side of Baga, and continued to fight with the wolf soldiers of the two states. Not to mention the steep mountain roads in this area, it is mainly dominated by stone mountains, and even the wolf soldiers in Siling Prefecture and Taiping Prefecture are difficult to advance normally, not to mention that they have to brave the rolling stones, rolling logs and crossbow arrows on the mountain, and there is a stalemate for a while.

On the other hand, the wolf soldiers of Pingxiangzhou, under the leadership of its main general, attacked the Napai and Guozhushan areas from the left side. This line, together with a high ground on the south side, was the location of the Mozambican army's earthen artillery position, from which the Mozambican army carried out a counter-attack on Tanling during the battle of Tongdeng.

This general of Pingxiang Prefecture took the lead and personally led his cronies to charge forward. But the strange thing is that even though the artillery of the Gao family, which was ordered to support the wolf soldiers, the Mo army in the direction of Guo Zhushan never fought back.

Some of the wolf soldiers rushed forward in a hurry, but were stopped by the general. The main general judged: The front of the northeast side of Guo Zhu Mountain is the official road leading to Lang Mountain, and the rear of the south side is Bomou and Kuma Mountain. Moreover, now that the fog is thick, it is not clear about the distribution of the Mozambican army's earthen artillery and musket infantry, and it may suffer unnecessary losses if it rashly launches a charge.

So he asked the 30 light guns that came from the Gao family artillery to turn around and fire, and let people beat the drum of the decisive battle, and the wolf soldiers shouted and shouted, deliberately startling the snake.

At this moment, the Mo army really couldn't hold his breath, thinking that the artillery bombardment of the Gao family was about to end, and the decisive charge of the wolf soldiers was about to start, so he hurriedly entered the position and blocked the front line with various earthen cannons, fire door guns and other firearms.

According to the exposed firepower position of the Mo army, the commander of Pingxiang Prefecture quickly determined the deployment and then launched a fierce attack. He led the main force to carry out a longitudinal assault along the way from Napai to Guo Zhushan, concentrating the 30 light artillery pieces supported by Huang Zhiting to suppress the Mo army's arrow tower, and the infantry led by each Tumu quickly leaped forward and charged Guo Zhushan.

The Mo army desperately counterattacked with firepower, and the Mo army's native artillery on the high ground also carried out artillery bombardment along the way to the attack of the wolf soldiers in Pingxiang Prefecture - the fog was too great, and their earthen artillery was poorly accurate, and the random bombardment was really indiscriminate bombardment.

In the thick fog, the two sides engaged in a scuffle. The wolf soldiers of Pingxiangzhou held the bamboo spear that had just been equipped with a new spearhead and attacked fiercely, and after a hard battle, they won the second peak and continued to attack the main peak.

Because the Mozambican army also knows the importance of the battle of Langshan, and they also have a strange mentality - the Mo army is more afraid of the Ming army, but not very afraid of the wolf soldiers who are actually stronger in combat, plus the wolf soldiers have been in the initiative to attack, consuming a lot of physical strength, as a result, the two sides fought into a draw for a while, and once again played a stalemate.

Fortunately, the Gaojia light artillery unit launched a "concentrated fire" in the Bomou area, destroying the Mozambican artillery positions on the high ground, and the Mozambican artillery fire that blocked the wolf soldiers disappeared. Taking advantage of this opportunity, the general of Pingxiang Prefecture personally led his own soldiers to rush up, break through the Mojun trenches, chase and fight along the traffic trenches, and rush to the main peak.

The two sides carried out a melee battle of spears against bamboo spears on the main peak, and the main general of Pingxiang Prefecture was not afraid of death, leading people to rush left and right. At about a certain time in the battle, he finally captured Guo Zhu Mountain, annihilated more than 300 enemies, captured and destroyed 16 earthen cannons, and completed the combat mission. Subsequently, the main general led his subordinates to quickly move closer to Huang Zhiting's main force.

In the afternoon, the rain and fog became heavier and heavier, and it was already blurry ten feet away. Although the wolf soldiers of Siling Prefecture and Taiping Prefecture were desperate to fight and rush, they could no longer figure out the direction. One of them even led his wolf soldiers to the southwest to cross the battle demarcation line, helping a friendly army in Anping Prefecture to take down a certain high ground.

However, the fog was fair to both sides, and the wolf soldiers of the Ming army had killed the border under the banner of revenge after all, and the momentum was more fierce. At the moment of the battle, the main force of the wolf soldiers in Pingxiangzhou, with the support of Gaojia light artillery, still occupied the key points of the first line of Baga and Guozhu, and destroyed a total of about 500 enemies. At this point, the wolf soldiers of the state cleared the outlying strongholds of Kuoma Mountain, which means that the Eastern Route Army has approached the foot of Kuoma Mountain.

After beating Kuma Mountain, it is Langshan City!
