"t?n g......"

As officers along the entire front gave orders in unison, more than 5,000 North Vietnamese soldiers shouted and rushed out of the camp.

From this moment on, the fragile agreement between North and South Vietnam that lasted for just a few years disappeared, and the thunderous war drums sounded again.

Three days ago, when the entire South Vietnamese navy was exhausted at the mouth of the Zhengjiang River, Zheng Zheng, who was overjoyed, ordered the troops and horses who had arrived earlier to launch a test attack on the South Vietnamese fortification area while making arrangements for the aftermath.

These three days of probing attacks are tactically necessary.

On the one hand, the North Vietnamese army has not yet been assembled, and it takes time to mobilize troops, horses, food and grass. On the other hand, in a large-scale war with more than 100,000 people, there will definitely be tentative encounters in the early stage, and both sides need to know each other's background to prepare for the future.

Collect intelligence for large-scale attacks and defenses.

Three days later, the first formal large-scale land attack began suddenly.

If according to normal history, three days are used to warm up before a big war, the time is definitely not enough. Whether it is Annan or other countries in this era, large-scale sieges are usually carried out in months.

War records on a yearly basis are also common.

But this time it was different. Sheng Nan, the "Emperor" of the North Vietnamese, the leader of the military observation group from the Ming Dynasty, directly suggested that the North Vietnamese army start a full-scale land attack after three days of "understanding" research.

The North Vietnamese must take the expert guidance Sheng Nan put forward with caution, relying on the power of victory in the naval battle.

Of course, the sound of gunboats bombarding Thang Long Mansion also provided a strong footnote for Sheng Nan's opinions.

In fact, the North Vietnamese know very well: Isn't it because of the core driving force of "Ming Aid" that the reason why everyone worked hard and rushed to Zhengjiang this time? So in any case, as long as the military plan proposed by Sheng Nan is not particularly inconsistent with

Common sense means that no matter whether they feel comfortable or not, North Vietnam's decision-makers from Prince Zheng Zhi down will most likely implement it.

Sheng Nan's idea was simple: since the decisive factor in the final breakthrough of the fortified area was foreign arms, the North Vietnamese should launch a comprehensive attack as early as possible.

There are also hidden reasons for this.

From the overall "international" perspective, the Vietnam War is just one link in the newly launched Great Yan Kingdom's overall southward strategy. The faster this link is completed, the higher the evaluation of Sheng Nan from the rear.

As for the hasty launch of a land attack that will cause the North Vietnamese to bear unnecessary casualties...the evil imperialists will not care about the life and death of cannon fodder. Even from a certain perspective, cannon fodder will die more, and it will be more

It is conducive to "long-term peace and stability" afterwards.

After the military observation group made suggestions, the North Vietnamese decision-makers discussed and finally, as expected, formally agreed to launch a large-scale offensive.

Such an important battle cannot be missed for a certain force that wants to operate/use force in the South Asian environment in the next step. This is valuable first-hand information.

So early that morning, Sheng Nan led the young staff members of the observation group across the river by boat and arrived at the former enemy camp. He prepared various equipment, including high-end instruments such as cameras, and prepared to record the actual battle.

In the early morning, after the soldiers had a good meal, the scene at the beginning of the article appeared. Accompanied by the long sound of horns and military orders, the North Vietnamese army rushed out of the camp and formed a formation, and then slowly moved forward.

A large number of soldiers holding wooden shields were in the front, soldiers holding hook guns and swords and spears were in the middle, and in the back were long-range troops holding matchlocks and bows and arrows.

The horizontal formation of 5,000 soldiers was like a thick black tide, filling the entire front of the battlefield. What the tide had to face was a modern defense system composed of irregular trenches, horse barriers, stone walls, and fortresses.

Yes, in the 17th century when weapons and tactics were undergoing drastic changes, the South Vietnamese, who were guided by the military ideas of the Franji people, built this permanent fortress area on the south bank of the Zhengjiang River, which already possessed many characteristics of the defense systems of later generations.

.

Except for the barbed wire machine guns and other items that are missing due to the limitations of the times, the rest is almost the same as the civil defense line that travelers remember.

Not long after, after walking for almost a mile, the tide hit the embankment.

Generally speaking, this first wave of large-scale attacks was actually mostly tentative in nature, and neither the attacker nor the defender expected to produce any huge results.

This can be seen from the caution of the attackers. Most of the soldiers in the front line are holding thick shields, which is to offset the kinetic energy of lead bullets shot from the opposite side. And many of the soldiers in the middle of the formation are holding hook guns, which is to clean up

Obstacles on the battlefield.

The atmosphere became increasingly tense. When the attackers approached 50 meters away from the trench, as if they had made an appointment, continuous volleys of gunfire and loud shouts rang out at the same time.

It was the North Vietnamese soldiers who made the loud shouts. While shouting, the shield bearers in the front row raised their shields and bowed forward. After reaching the edge of the trench, these shield bearers supported their shields on the ground.

The soldiers in the middle began to use hook guns to pull the numerous horses.

A common scene in movies and TV shows appeared in the sky: black arrows filled the sky, and the visual effect was excellent.

At the same moment when the North Vietnamese's three-blade ax was launched, the first round of volleys of gunfire was fired from the stone wall and fortress less than 20 meters away from the opposite side of the trench.

The distance of the trench was accurately measured to maximize the power of the matchlock gun. Therefore, despite the thick shield, under the intensive shooting at this distance, layers of soldiers still fell down with the sound of volleys of gunfire.

The Yue people, who had been fighting for many years, were already used to the sight of dead people. The soldiers on the offensive side were unmoved and used every second to complete the task.

The so-called race against time is also a painful lesson learned by the North Vietnamese after the last time a large army came to charge into the battle. The South Vietnamese would not allow their opponents to calmly remove obstacles on the battlefield.

Sure enough, the next moment, a huge noise overwhelmed the noise on the battlefield: South Vietnamese artillery was fired.

The Portuguese, who were the first to come to East Asia, established relations with indigenous governments in various places by relying on the arms trade, and were important disseminators of war technology.

The Portuguese not only opened the Bugalao Cannon Foundry in Macau during the Ming Dynasty, but also opened a cannon factory in Hue, the capital of the South Vietnamese regime.

This is also the key reason why the South Vietnamese separatist regime was able to rely on fortified areas to maintain the country for more than a hundred years in history: no army in this era can withstand the three-dimensional attack of hot weapons.

The South Vietnamese who have been guarding the stone wall all year round certainly do not do anything but play TikTok every day. The artillery shells fired from behind the stone wall are accurate and hard, and it is obvious that the shooting elements have been determined long ago. Whenever a certain artillery on the defense line fires a projectile

, it must have hit the middle of the crowd with a high probability.

The effect of the shelling was immediate. Although there were not many cannons fired, most of the shells, whether they were small-caliber French muskets or 6-inch cannons, carved a bloody path through the crowd.

At this time, the attackers could no longer hold on. The formation was obviously loose and deformed under the bombardment of artillery fire, and the morale of the soldiers was visibly declining.

At this time, the North Vietnamese general standing on a wooden truck behind the formation put down the single-tube export-type telescope in his hand and ordered the trumpet to be blown at the right time.

After the Ming Dynasty, the North Vietnamese quickly retreated. Although they were local troops transferred from various places, the North Vietnamese troops who had been fighting all year round were of high quality. When they retreated, they not only took away the Juma, but also took away the bodies of the casualties.

.

The effect of the first attack was undoubtedly acceptable to both the offensive and defensive sides. The attackers demolished some obstacles and tested the strength of the South Vietnamese defense line. The South Vietnamese used thermal weapons to kill many people.

Conquer the enemy and the exchange ratio is satisfactory.

In addition to the South Vietnamese on the battlefield, there was another person who was also quite satisfied: Sheng Nan.

"Not bad, not bad!" While the North Vietnamese retreated in an orderly manner, Sheng Nan observed the battlefield with a telescope and nodded repeatedly: "The defense was organized and the retreat was timely, very nice."

However, after putting down the telescope, Sheng Nan, who was responsible for teaching, became serious: "Are all the fire points marked?"

"The report has been marked. Based on the size of the muzzle flash, the artillery caliber of the enemy's firepower point has been preliminarily marked."

"Yeah." Teacher Sheng just nodded slightly when he heard this, then raised his finger to point to the Vietnamese army in front of him who had withdrawn to a safe distance, and commented a few words: "This is an army with considerable military literacy. You will meet in the future,

You must not be careless. In my opinion, except for our regular army, other auxiliary forces cannot surely defeat them, even if we have the advantage of firepower."

"As for the soldiers and horses of the imperial court..."

Sheng Nan said this and shook his head: "Do you understand what I mean?"

"My subordinate understands!"

Seeing the dozens of young and energetic faces in front of her, Sheng Nan continued to tighten her face the next moment: "Now let's start assigning homework."

"Take the fortified area of ​​South Vietnam as the imaginary enemy, without naval gun support, and our regular army and pioneering army as the attackers. Each of you must come up with at least two tactical plans before tomorrow morning, and you must have operations on the map.

."

"Guaranteed to complete the mission!"

————————————————————————

Next, on the first day of the offensive, the North Vietnamese organized and launched three large-scale attacks on the South Vietnamese fortification areas in the morning, afternoon, and evening with an overwhelming shock wave.

In the last one, the number of people increased to ten thousand, and the casualty rate increased significantly. The battle situation could be said to have reached a climax from the first day, and it was undoubtedly very tragic.

However, there were results: at least a thirty-meter-wide trench had been filled with human lives by the North Vietnamese, waiting for a close-range attack the next day.

And that very night, the North Vietnamese frontline general came to the door in person and humbly asked Sheng Nan to order the use of the large mortar "Gronde" for use on tomorrow's battlefield.

Sheng Nan agreed without hesitation.

...Although that mortar belongs to the "Ming Yuan" and is nominally an arms gift to the Yue people. However, the arms made with modern technology are not something that the Yue people can use at all. The supporting gunpowder and cannonballs

, and even the supporting artillery battery, these are all in Sheng Nan's hands.

This routine was used in later generations. One family said it was second and no one dared to say it was first: Ermao.

His various tricks towards India are really amazing.

However, the next moment after the Vietnamese general went out, four or five people in the field tent, led by Staff Officer Yang Weili, stood up and excitedly suggested to Commander Sheng to postpone the mortar support. The reason was simple: the blood of the Annan people was flowing.

Too little.

After Sheng Nan quietly listened to the staff's reasons, he was not angry. In fact, with a calm expression, he was quite pleased: "Yes, they all have an international perspective. It seems that Han Xiaobo and others have done some practical things in the past few years.
Chapter completed!
