Later history books (of course, the Chinese ones) describe this period of negotiation between the Vietnamese Le Dynasty and the Trung family: both sides had a sincere desire for friendly cooperation, and soon reached an intention to cooperate, and on the basis of equality and mutual benefit, a series of cooperation agreements were reached, according to which the Chinese army entered Vietnam, fought side by side with the Vietnamese army, and soon expelled the invading pirate group. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info upheld Vietnam's independence and freedom......

This description is not incorrect, but the Vietnamese often have different views on whether the agreement really upholds Vietnam's independence and freedom.

In short, the envoys of the Li Dynasty and the envoys of the Zheng family had frank negotiations on the issue of a joint crusade against the Australian pirates on the territory of the Australian pirates. Eventually, the Trung family got their wish and obtained the right to explore and mine coal in northern Vietnam, and the scope was expanded to cover the entire north of Thang Long province. Of course, their mining activities had to be carried out under the supervision of the Lê dynasty, and the coal mined was also taxed to the Lê dynasty on the basis of weight and the rate agreed upon by both parties. Of course, according to later Vietnamese history, the Trung family soon used the money offensive to win over and corrupt a large number of Li Dynasty officials related to mining taxes, thus making the system of collecting taxes according to the total amount of mining extinct in name only. In the later period, it even developed to the point that the extraction tax of these coal mines was not even sufficient to pay the salaries of the tax collectors who supervised it.

In return, the Zheng navy and the Li Dynasty army cooperated with each other to quickly expel the "Australian pirates" who occupied the mouth of the Red River, and handed over some of the captured weapons to the Li Dynasty army. At the same time, they also promised not to sell weapons to the Nguyen kings in the south, and sold a batch of cuirasses and artillery to the Lê army at a favorable price. And by arguing with reason, Wu Wenyong even forced the Zheng family to sell the latest flintlock pistols to the Li Dynasty army, instead of the old-fashioned arquebuses that were also armed in the south.

In addition, the Zheng family's fleet also successfully intercepted the fleet of "Australian pirates" and forced them to surrender, so that a group of Vietnamese who had been plundered by the pirates, loaded onto ships, and prepared to be transported overseas to work as coolies could return to their homeland.

There are very large open-pit coal mines in northern Vietnam, which produce high-quality anthracite. In addition, although the associated coking coal reserves are not large, they are enough to support the development of Hainan Island.

……

Gan Hui and Yu Xin, officers of the "Australian Haikou" and officers of the Zheng-Li coalition army, who had just been quickly defeated by the Zheng family and the Li Dynasty army, have now returned to Taiwan and reported to Zheng Sen about this battle. At the same time, he accepted Zheng Sen's new orders.

"As you mentioned earlier, after the battle, the soldiers improve very quickly, and the battle is the whetstone of the army. I think that's true. So, I've decided to help you find something that you can control the intensity and keep you engaged in the battle. New news came out from Luzon, and the natives gradually organized. And they got quite a bit of heat from the Spaniards. Soldier. instrument, and even some small cannons. However, the firepower and organization of the local natives are still not comparable to ours, so this is a very suitable training ground. The Army guys are already starting similar training there, they'll be there for three months, and then it's your turn. I have here some information about the situation on Luzon, and you can take it back and prepare in advance. ”

……

While the men of the Marine Corps were seriously studying the materials about Luzon Island, Lu Chen, the commander of the cavalry company, was making the final preparations before the battle, and a cavalry company of the army was among the first to come to Luzon for training. Compared with the infantry, the cavalry of the model army has almost no combat experience, so it also needs to be trained in actual combat.

Lu Chen's cavalry company was all dragoons, that is, musketeers on horseback. However, unlike the European dragoons of this era, who were generally armed with two pistols and played with wheel shooting on their horses, according to Zheng Sen's vision, their combat method was to increase the mobility of the battlefield by riding horses, dismounting in the face of a well-organized enemy, fighting like ordinary infantry, and once the enemy army was defeated, they had to use sabers like light cavalry to solve the fleeing enemy. This means that dragoons should be versatile, and they need to master the most skills. Zheng Sen even hoped to replace the light cavalry in the usual sense with them.

According to the original plan, the dragoons were supposed to use horses that were crossed between Arabian and Mongolian horses. It's just that the number of Arabian stallions is limited, and the crossbred foals are still small and few in number, not enough to support a cavalry team. Therefore, now Lu Chen and the others are still using ordinary Mongolian horses. However, considering that the natives did not have horses in their hands, although the Mongolian horses were a little shorter and not fast, they were quite sufficient.

During this period of time, neither the Chinese side nor the indigenous side did not have much action, the Chinese have grabbed a lot of territory, and now there is a shortage of manpower, although some time ago, a lot of Chinese were transported from the Ming side, but these immigrants are not strong enough, and, at least for now, they have not been able to complete the training and become an effective combat force.

The situation is similar on the indigenous side, they do not have the problem of shortage of manpower, but it is precisely because of the large number of people, so the Spaniards did not give them many good things at first, (the Spaniards felt that the natives relied on the large number of people, as long as a little decent weapons were enough to ensure balance) It was only after the things in the hands of the Chinese that they began to provide arquebuses to the natives. As for flintlock muskets, at this time, even in Europe, there were not many armies armed with flintlock muskets. In Luzon, the Spanish army did not have many flintlock pistols, so the natives naturally did not have flintlock pistols to use.

The arquebus is even more cumbersome in operation than the flintlock gun, and in order to use it well, it naturally requires more training, otherwise, in the absence of good training, the arquebus may not even perform as well as the spear and the javelin. Therefore, the Spaniards also sent instructors to the natives to train them. This kind of training is naturally time-consuming, so both sides have been quiet for a while before.

But this peace will soon be broken, and now that the training on both sides is almost underway, and a lot of money has been spent, if there is no war, won't all these investments be wasted? So, everybody is getting ready to do something.

Two days ago, a group of Chinese sent several large truckloads of goods to one of Boss Jiang's villages. This Zhuangzi is a salient on the dividing line between the Chinese and the natives, and its three sides are the territory of the natives, if the natives want to do something against the Chinese, this manor of Boss Jiang is definitely the most convenient target for attack. However, from another point of view, if the Chinese want to attack the natives, it is also the most convenient to start from Boss Jiang's Zhuangzi.

At dawn, several large carts of goods were quietly delivered to Zhuangzi by a group of armed Chinese escorts. But that didn't hide it from anyone. In fact, both the natives and the Spaniards kept a close eye on Boss Jiang's special Zhuangzi, and using the telescopes they got from the Spaniards, the indigenous sentinels discovered the movements of the Chinese and saw several large truckloads of things being transported into the Zhuangzi.

Before that, the Spaniards had learned of the news through their own channels, that is, the Chinese had bought a lot of gunpowder from the Dutch. The quantity seems to be very close to the amount of goods that are being shipped to Zhuangzi today.

"If the Chinese are going to attack, then they will definitely use this village as a starting point for the attack. You see, it's very convenient to start from here, whether it's attacking here or here. A Spanish officer pointed to a map and said to the indigenous chieftain Aquino, "But if they want to attack this village as a fulcrum, then they will definitely store some supplies in the village first, such as gunpowder." ”

"Captain Olsen, do you think we should defend there?" Aquino said with a frown.

"No, no, no. Mr. Aquino, you are not right. "You see, from this position, they have at least three possible targets. And if we defend every village, then most of the forces we have gathered in any village will not be able to defeat them, and our reinforcements, if they want to go to support, must first bypass this village. As a result, our reinforcements will be very slow and may not be able to complete the rescue. So, Mr. Aquino, I think the best way to fight in such a situation is not to defend, but to take the initiative to attack. ”

"Take the initiative? But, Captain, you know, that village is not easy to fight. Aquino's face changed a little, and he remembered his last failed attack.

"You're right." Captain Olson said, "That Zhuangzi is indeed not easy to fight. Their walls have been strengthened several times and are also armed with artillery. Under normal circumstances, it's really hard to get it down. But what if they take the initiative to attack our village, and we take advantage of the departure of their army and the decline of the garrison, and hit the forces to attack it? ”

"Nope." Aquino still shook his head, "They're not that stupid, they'll definitely leave the forces behind for defense." ”

"They are left with the forces they thought they could hold the village, but, Mr. Aquino, they don't know that you have just been given a more elite army, and weapons that you have never had before."
