With Yu Xiaotian's order, the Sea Wolf troops immediately began to prepare, and according to the arrangement of the logistics office, the ships that returned to Nanri Island were moored near the dock one by one, and began to receive supplies in turn.

The sailors who were on leave on the island were also ordered to return to the docks at once to report to their respective ships, and the sailors, under the leadership of the captain and first mate, carried out the final inspection before sailing.

This time, Yu Xiaotian did not choose anyone to command the fleet for him, but decided to personally lead the fleet to Jilong Bay to command the operation against the Spaniards this time.

While the others were busy preparing for the voyage, Yu Xiaotian gathered the main generals of the fleet into his council room and began to discuss the battle plan.

Recently, many ships in the fleet have been sent to various places on the sea to strengthen the control of the sea surface, and many raiders have also been sent to the sea of Liangguang to operate, and there are also newly established fishing grounds that need to be patrolled and protected by ships, so the number of ships that the sea wolf can assemble in a short time is not very large.

In three days, the number of ships that each detachment rushed back to Nanri Island was no more than forty, including some of the Feizi clippers that had just been launched.

Although these newly launched Feizi clippers have completed their equipment, the sailors on board have not yet finished their training and have not yet completed the run-in with the ships, but considering the particularity of this operation, these Feizi clippers will play a decisive role in the battle situation, so these ships are also ordered to participate in this operation.

In order to ensure that the new crews of these ships would not make serious mistakes in wartime, Yu Xiaotian ordered the mature sailors of other Feizi clippers to be assigned to some of these new ships to strengthen their strength.

In fact, before this, Yu Xiaotian had already known that sooner or later a conflict would break out between the sea wolves and the Europeans, whether the Spaniards or the Dutch, so in the past year, he had discussed with his subordinates many times how to deal with these European fleets or warships.

To this end, they also used the brig schooner as an imaginary enemy, carried out many simulated battles at sea, and organized the Feizi clipper as an imaginary enemy, and let the Seawolf sailor fleet conduct a simulated battle with it, so that the Seawolf troops gained a certain amount of experience in fighting with Western-style warships or fleets.

And according to the results of several simulated battles, they have also formulated some tactics to deal with them, so when they decided to go to war this time, they were not in a hurry, only after a brief discussion, Yu Xiaotian decided on the battle plan for this battle of Jilong Bay.

Among the fleets sent by the Spaniards to Jilong Bay this time, there are several large ships that act as the main force, these large plywood ships have strong firepower, and the sides of the ships are high, the speed is also fast, and the hull is solid, with ordinary Chinese-style ships, even the No. 2 Fu boat, compared with it, it is a small thing, both in terms of firepower and hull.

Therefore, if they want to adopt a gang jumping battle, the outcome will definitely not be very good, and it will be difficult to work, and the only thing they can rely on is the advantage of the number of ships, concentrate firepower to hit some of the main ships first, and would rather pay a certain price, but also sink or damage them, so that they lose their combat capability.

Therefore, if they don't go this time, once they appear on the battlefield, they must all strike a thunderous blow to the Spanish fleet and directly fight out a few of their main warships to have a chance of winning.

Fortunately, they now have some flying clippers, which can be used as a magic weapon to defeat the enemy, these flying clippers have a high flexibility and speed advantage, although they are inferior to the enemy's main ships in terms of firepower, they can easily contain the small boats brought by the Spaniards and knock out their small boats first.

In this way, as long as these boats are killed first, it is equivalent to stripping the Spanish fleet of clothes, although they seem to be very strong, but the remaining main warships, there are clumsy shortcomings, and then the sea wolves can use the advantage of numbers to drown them alive, as long as they are separated, they are basically like women who have been stripped naked, and they can get on as much as they want.

For Yu Xiaotian's arrangement, Ma Xiao, Liu Yidao, One-Eyed Dragon, Luo Xianbin and other commanders of the First Dry Water Division all agreed to this, this is the best tactic they have come up with after previous drills, except for this, they have no better way at the moment.

In addition, Yu Xiaotian also emphasized one point, that is, it is estimated that the waves will pay considerable losses in this battle, whether it is people or ships, the losses will not be too small.

But the sailors of the sea wolf are really a very valuable asset to the sea wolf, and Yu Xiaotian never treats his subordinates as items that can be consumed at will, allowing them to be consumed.

Therefore, this time, he asked the fleet to be accompanied by a considerable number of speedboats, which were mainly manpower rowing boats such as Changlong and fast pulp.

Although some of these ships had sails, their main power was manpower paddling or rowing, and although the firepower was very weak, and each dinghy could only be loaded with a six-pounder or a twelve-pounder cannon at the bow, it was quite flexible in the battlefield, and it was a good way to restrain large ships.

These boats can suddenly burst out of the fleet in the middle of a scuffle and carry out a sneak attack on the enemy's large plywood ships, and the Seawolves now have quite a few Molotov cocktails.

At the end of last year, a batch of oil ordered by Yu Xiaotian from the Portuguese finally arrived after more than half a year.

The Portuguese don't know why the sea wolf is so interested in this kind of thing, this thing smells so bad, it smells bad, it can neither be eaten nor used for anything else, it seems to be of great use except that it can be burned, and the sea wolf does not hesitate to ask them to find a way to get some of it.

The Portuguese are now very satisfied with the customer of the sea wolf, they originally did not sell much to the Chinese, more rely on collecting silver everywhere to buy things from the Chinese, now the sea wolf does business with them, but is willing to buy their things, although oil is not easy to get, the value is not very high, but since the sea wolf needs, and they can also make money, so these Portuguese still try to get some for the sea wolf.

These sticky things were all packed in some large wooden barrels, and this time more than a dozen tons were brought to the sea wolf.

After Yu Xiaotian received these oils, he did not immediately use them as kerosene, after all, if this thing is not refined, it is not very easy to ignite, so he built a set of extremely rudimentary equipment on Nanri Island, simply refined it, and used distillation to refine some mixtures of gasoline, kerosene, and diesel, leaving a batch of heavy oil.

These refined oil mixtures are much better than whale oil filled incendiary flasks, this thing is extremely flammable, and the burning is very violent, as long as it is ignited, it is difficult to extinguish with water, it is a great weapon in naval warfare, but the quantity is too small, this thing is really not easy to get, and the price is also very high, it cannot fully meet the needs of the sea wolf, although Yu Xiaotian asked the Portuguese to continue to provide them, but it is difficult to guarantee that this kind of thing is obtained a lot.

Naturally, the oil was so precious that it was carefully stored in glass bottles, and this time a portion of it was taken out and given to the fleet as a weapon against the Spanish ships.

When this thing is refined, it is very wasteful, and the danger is very high, Yu Xiaotian personally supervised his craftsmen, refining it by atmospheric pressure, and it may cause a fire or explosion if he is not careful, and finally made such a little bit of unclear composition of petroleum products, this thing can be said to be on the soil law, and it took a lot of risk to obtain, so it is precious, under normal circumstances, Yu Xiaotian is reluctant to take it out and use it.

As for the remaining heavy oil, although it can also be used to fill Molotov cocktails, but considering that they do not have enough lacquer to paint the ship at the moment, these heavy oils can be applied to the bottom of the ship, which is very adhesive and can play a good waterproof role, in addition to reducing the attachment of marine organisms to the bottom of the ship and prolonging the time for the sea ship to clean the bottom of the ship.

In addition, heavy oil is also a very good fuel for steelmaking, this thing has a large calorific value, considering that he may go to the soil method steelmaking furnace to make steel in the future, so this thing is also a good fuel to add fuel, which can increase the furnace temperature, so these refining leftover heavy oil is also properly stored, on the one hand, it is used to coat the bottom of the ship to prevent sea maggots from eroding the hull, and it can also reduce the attachment of marine organisms, on the other hand, it can be used as fuel after the soil method steelmaking road is launched.

In short, these things are not things that can be thrown away casually, and they have all been thoroughly used by Yu Xiaotian.

Although Yu Xiaotian began to prepare as soon as he learned the news, after all, it was impossible for the fleet to stay on Nanri Island every day, waiting for the Spaniards to come to the door, so even if he started to assemble the warships as soon as he got the news, but in this time and space, such means of communication and sailing speed still need a while.

From the time he began to assemble the fleet to the final preparation for departure, it took six days before he was basically assembled and replenished, and he was ready to sail.

However, Yu Xiaotian is not too worried that Keelung Fort will be captured by the Spaniards, because the overall defense facilities there have been basically improved, although the remaining ships are definitely not the opponents of the Spaniards, but the Spaniards want to capture Keelung Fort, it is estimated that there is not much possibility.

There is not much difference between the two sides in terms of the quality of firearms, the Spaniards have some advantages in the number and caliber of the fleet's artillery at most, but in terms of the quality of artillery and muskets, it is the sea wolf side that has a lot of advantages, although the flintlock pistol has now appeared in Europe, but the flintlock device is not perfect, and most of them are complex structure of the rotary musket, the price is high, the operation is complicated, and it has not been popularized.

The Spaniards are still using old-fashioned arquebuses, which is a generation behind the sea wolf's flintlock pistol, so with the strength of the Spaniards alone, it is okay at sea, but if they attack Keelung Fort, they will definitely be broken off their big teeth, so this is also the reason why Yu Xiaotian is not in a hurry to rush to Keelung Fort to support.
