Yu Xiaotian watched with satisfaction the performance of these passionate bare-chested captives, everything was expected by him, because according to his understanding of human nature, when a person loses everything, including the most basic dignity, that kind of despair will make him crazy.

And he let these Spanish captives suffer enough in the quarries, and live without dignity, (these people have barely worn clothes since they were captured!). He could imagine the anguish in the hearts of these people.

Now, not to mention that he had made such good terms for these people, even if he had only promised to give them clothes to wear and feed them, he believed that these captives would immediately beg him to serve him like flies seeing blood.

But he still gave these people more favorable conditions, only requiring them to serve themselves for five years, which gave these people hope, in these five years, they would not be passive because they could not see the hope of the future, and they would not be passive and slack off, in order to make them work harder for themselves, he did not hesitate to pay these prisoners, and it was not too low, so that these prisoners could be more inspired to serve him seriously.

He took a fancy to these captives because they were still very useful to him, and among them, especially the sailors, were good at operating Western-style galleons, although it was impossible for him to return these two Western-style galleons to these fellows to operate.

But he can take advantage of these sailors, especially some of them experienced old sailors, who have high navigation skills, especially ocean-going navigation skills, which are not currently available to the Chinese.

Even he, who had returned to this era from the future, did not have the skills of these Spanish sailors.

At present, the Chinese are still accustomed to sailing along the coastline, keeping within visual distance from the coastline, relying on landmarks along the coast to indicate the course, at least some islands along the way to provide them with guidance, although the Chinese have also been using the compass to indicate the direction, and will also use astrology at night to help find the direction and determine their position.

But the Chinese never created the concept of latitude and longitude, and Western navigators have now created more perfect navigational techniques, and have also invented the telemeter, the rectangular instrument and the quadrant, the most important of which is the quadrant, that is, the quadrant, so that they can determine their position in the sea through the quadrant.

So far, few Chinese have understood this, and on the two Spanish ships captured this time, Yu Xiaotian found a quadrant.

And this kind of quadrant is not used by him at present, but he knows some principles of the way, for the sextant, he knows what the way is the way, but at the moment he does not need to "invent" this kind of sextant, because for the time being, he does not need to let his subordinates sail far away, and when he wants to let his men sail around the world one day, he will naturally get this kind of navigation artifact.

For the time being, he needed these experienced Spanish sailors to train him to be seafaring crews to prepare for the future, and these people would be of use.

And to operate these two large plywood ships temporarily, he also needs these Spanish sailors to teach his subordinates how to operate these two ships, or three, because the other Spanish shipwreck that was sunk in the area of Jilong Bay, at this time, Yu Xiaotian had already arranged for people to go over, mobilized several large sand boats, and began to salvage the ship.

If all goes well, the ship should be salvaged from the water in ten days, temporarily at Keelung Fort for basic maintenance, to see if it has any repair value, if so, the ship will be towed to Nanri Island or Tamsui Bunker for further repair work.

And among these captives, there are a few doctors, these doctors know some Western medicine, although Western medicine is not developed in this era, there are still many fallacies, but they can also be used to some extent, and the sea wolf's medical officers have some academic exchanges, so that the sea wolf's medical officers can absorb some Western medical techniques.

Even those Spanish infantrymen, they can't be said to be useless, these people are mostly mercenaries, each of them can skillfully operate arquebuses, and they are familiar with the formation of the Spanish phalanx, which can also allow him to absorb some of the current infantry combat methods of Western countries.

Before the invention of the rear-loading rifle, the combat method of platoon guns and guns will last for a very long time, these Spanish infantrymen still have a certain role, after all, he made a combat phalanx in the war barracks through hearsay in later generations, and some places are still a bit nondescript, with these Spanish infantry, he can make the infantry phalanx of his combat battalion more perfect, plus he knows more infantry tactics, so that his infantry combat effectiveness, It can surpass the combat effectiveness of the infantry phalanx of other countries in this era.

Of course, even without the addition of these Spanish infantry, after he began to equip his subordinates with a large number of wolf tooth rifles, the sea wolf's combat battalion will quickly become the strongest infantry in this world, because of the advantage in range, they can give the enemy a fatal blow from 300 paces away, and even if the enemy has the best arquebus at present, it only has an effective range of about 70 meters, and in most cases, the enemy can only have an effective range of about 50 meters at most, his soldiers, You can use the wolf's tooth rifle to easily defeat the opponent from a long distance without waiting for the opponent to form a queue.

Even if it encounters the enemy's cavalry, his infantry will not suffer, because even the strongest Tatar cavalry at the moment, when launching a charge, must be two hundred steps away to start the horse, beyond two hundred steps, the horse will not be able to accelerate to the fastest speed, and maintain enough physical strength, if you start too early, when you rush to the front of the enemy, the horse has often lost its fastest speed and impact.

And 200 paces is also the most effective shooting range of the wolf's tooth rifle, and before the opposing cavalry starts to charge, his musketeers can already have more time to inflict heavy damage on the opponent by concentrating fire salvo before the enemy team can charge.

However, he still didn't mind absorbing some Spanish infantry to help him improve his current infantry tactics, which would be of great help to continue to improve his infantry combat effectiveness.

So these captives, without exception, all chose to sign a contract to serve him for five years, and after signing the agreement, these captives began to be re-screened, in fact, before that, when these prisoners were in Keelung Fort, they had already made a register of their directors, and this time the re-screening was just to ask them to supplement their strengths, and try to make the best use of their talents in the future.

All the prisoners brought the first batch of personnel to serve, the total number was 876, of which the infantry accounted for more than half, nearly 500 or so, and the sailors accounted for more than 300 and less than 400, because in the battle of Jilongwan, except for the first batch of heavy losses sent to attack the battery, the rest of the infantry was basically peacefully disarmed, so the losses were not large.

The sailors, on the other hand, suffered heavy losses, and were killed and wounded in the fierce battle, some of whom sank into the sea with the ship and drowned, and in the end less than 400 people were captured.

So these people were reassigned according to their strengths, the infantry really had no strengths, and were assigned to the garrisons of Keelung Fort and Tamsui City, as ordinary soldiers, and were used in the battle sequence, and some members who were proficient in infantry tactics were assigned to each combat detachment with the position of tactical instructors, and the other group of people were assigned to the new barracks of combat soldiers as tactical instructors or gunnery instructors.

However, any prisoner who becomes an instructor can receive a higher salary, while a prisoner who is an ordinary soldier can only receive the most basic salary, of course, if they make meritorious contributions in battle, then there are additional rewards.

As for the sailors, two of the captains, as well as several boatswains and navigators, were assigned to the naval recruit battalion as instructors and received the highest salaries, while ordinary sailors were assigned to the sailors and served as gunnery instructors in the battalion, or ordinary sailors.

In this way, the sea wolf has a lot of more people at once, and these people are professionals, which can play a good role in promoting the quality of the sea wolf army and the land and water army in the future.

Although the seawolf's gunnery is the best among its peers, there is still a lack of systematic education in the operation of artillery, especially in the calculation of long-distance artillery bombardment, and it is only carried out by their exploration, and among these Spanish sailors and infantrymen, many of them have received professional gunnery training, and the overall quality is beyond the gunners of the seawolf, and the reason why they are used is also to let the seawolf draw some more practical experience and skills from them.

However, in terms of the use of these people, Seawolf adopts surveillance and use, especially for some people who were former officers, and even more monitoring.

Yu Xiaotian also gave these former Spanish officers a task, that is, they were asked to submit some military regulations and training methods they knew in writing within two months, if they wrote well, they could be given a high additional reward, but if they were perfunctory and unwilling to write carefully, their salaries would be deducted, and they would be demoted, or even sent to the quarry to continue to work as coolies.

Yu Xiaotian has always had a headache for the preparation of various regulations, because he himself is not a soldier, and he has limited knowledge of the regulations formulated by the army, so he can only grope for the formulation of some regulations and norms, but it is always not systematic enough, and there are many deficiencies.

These things are exactly what Yu Xiaotian and the sea wolf need, and Yu Xiaotian plans to squeeze out what they have learned as much as possible during the time that he can use these people, and then revise them for his own use.
