At this time, the Thermal Shelter Fortress was not yet perfect.

Due to time constraints, the Dutch people have not yet captured a large number of migrant workers from Nanyang, and only captured the fortresses built by local ethnic minorities.

At this time, the Thermal Barrier Fortress was only a European polygonal fortress built on a piece of high ground according to the terrain, and the outer fortress on the west and south sides was only one floor, and the inner high ground gradually increased in a stepped manner, and the fortress gradually increased.

There were only more than 100 cannons inside, all of which could be fired outwards from the window, which was the firepower of three Galen warships according to the number of cannons, but the walls of the fortress were all made of rubble masonry.

The rubble shrinks inwards and looks so solid that even if it is bombarded with cannons, it can only break the rubble, and there is a rammed earth wall behind it, which is quite thick, unless every shell hits the same spot.

After 38 years in history, the Thermal Barrier Castle must be much stronger than it is now, and Zheng Chenggong's cannon at that time was at the level of Hongyi Cannon, but it was impossible to bombard the fortress with a cannon, which shows how strong the Thermal Barrier is.

But at this time, the strength of the Ming army under Wang Hongyu was much more powerful than Zheng Chenggong in history, and the power of his hot weapons was incomparable to Zheng Chenggong, and the hot blocking castle at this time was just a simple fortress.

There were 50,000 Ming troops on the island, plus the follow-up forces to occupy the Penghu Islands and the coastal areas of Fujian, as well as personnel in logistics support, and a large number of Japanese prisoners, with a total number of at least 200,000.

The materials and grains consumed every day are massive, and all of them are close to the funds accumulated by the five southwestern provinces and the industrial and commercial development of the south in the past two years.

At any time, wars are fought for money and food.

In the previous life, the late Ming Dynasty was destroyed because of lack of food, lack of money, and continuous losses of field soldiers.

The Netherlands also had 15 Galen warships in Putmans, with 600 Hongyi cannons on board.

Although the Ming army had far more warships than the Dutch warships, there were fewer new warships and the caliber of the ship's guns was inferior, and the decisive battle from the sea was not at all the opponent of the Netherlands.

However, Wang Hongyu will never attack the other with his own shortcomings, and when building the castle, he only considered preventing the Ming army or Aceban duck from attacking from the sea, and it was difficult for the ship's guns to bombard the castle in the sea, and it was only possible to enter when the tide was high.

However, the Ming army had already occupied the treasure island, and had already surrounded the Resha Castle on land, except for the sea to prevent the Dutch from attacking, and no Ming army was arranged, and the rest of the place had been besieged.

The Dutch ship-based guns simply looked at Lu Xing, their ship-based guns could only hit the vicinity of the Resha Castle, and they had already tasted the suicidal suffering of fireships against the Ming army's navy, and they did not dare to fight against the Ming navy anymore.

In fact, Wang Hongyu knew that with the strength of the Dutch Navy, the Ming Dynasty had not yet destroyed the strength of the 15 Galen warships in the Netherlands, and it was still certain that he would take down the Resha Castle from land.

Wang Hongyu and Xiong Tingbi, Nan Juyi, Yu Zhigao, and Zhang Mingshi agreed on the overall strategy.

Xiong Tingbi is responsible for the specific arrangement of the front line.

There are dozens of Hongyi cannons in the Hunhe Army, and there are countless general cannons, Fulong machine guns, and tiger squat cannons.

This time, the Ming Dynasty occupied the land first, dug trenches from the surrounding areas and advanced steadily, made camouflage nets with grass and trees, and transported the cannons to gun emplacements suitable for firing the enemy.

In the future, the artillery of the Ming army was specially aimed at the enemy's artillery position.

In addition to the solid shells that blew up the stone wall, incendiary shells were also used, and the artillery shells of the Ming army disrupted the cannons and gunners, and the powder keg behind the gunpowder barrel caused an explosion, and the nest exploded in the fortress, causing a chain reaction.

The Ming army mobilized the sappers who built the military cantonment, on the one hand, the artillery suppression, on the other hand, the sappers advanced in the trenches, earthwork, and buried explosives under the fortress to blow up the gap.

After the distance was closed, the enemy's heavy artillery could not hit the target at close range.

The tiger squat cannon in the Daming trench can be powerful. There are also sub-cannons, which are easy to use at close distances, and the rate of fire is particularly fast.

The Dutch people don't have many small cannons, and the Hongyi cannons cannons can't be used within fifty paces.

There were only a few small cannons in the castle, and in the face of the various shells constantly flying from the gap, the artillery battle of the Dutch defenders was completely defeated, and the morale of the Dutch defenders followed

and falling.

At this time, the enemy fleet could not care about injuring its own people by mistake, and began to fire heavy artillery at the Resha Castle, because the distance was too far, the shells lost their accuracy, and most of them fell in the Ming army area outside the city, and a few fell into the castle.

The shells that fell outside the castle were far away from the attacking Ming army, and only played a role in preventing the Ming army from advancing. However, the shells that fell into the castle were tantamount to attacking from behind the Dutch defenders, and casualties naturally occurred from time to time.

There were too many shipborne guns in the Netherlands, and although they had not yet injured the attacking Ming army, they could not continue to advance. The Dutch ship-borne artillery continued to shell support, which was a great deterrent to the Ming army.

However, under the planning of Wang Hongyu and the command of Nan Juyi and Yu Zhigao, the fleets of Fujian and Nanzhili of the Ming Dynasty could not defeat the fleet of the Netherlands in a decisive battle. But the shells of the fleet are depleted, and they cannot be replenished close to the thermal shield that is being fought.

"It's time!"

Nan Juyi and Yu Zhigao led the Fujian naval division to launch an attack, taking advantage of the enemy's warships to anchor to support the land, the new warships seized the upper hand, and the old warships used wolf pack tactics to surround an enemy ship and go up, it didn't matter if they were unsinkable, they could destroy their decks and sails.

Chain shells can also break the mast on the Dutch Galen, rendering it unpowered.

The cannon on the other side of the Dutch Gailen battleship was not idle, and kept firing back at the Ming Navy, and also damaged the Ming Navy battleship.

The two sides fought fiercely for many days, and when the tide rose on the 16th, Nan Juyi commanded several warships to rush into the island river.

Many small cannons on land and water rained shells and shotshots into the castle from the gap, and by this time the Dutch defenders had already lost more than half of their dead and wounded, and could no longer support it, and there was no ammunition left, and a large amount of ammunition was supplied to the Galen battleship last time.

Daming also brought large and medium-sized artillery on land one after another, concentrated artillery fire support, and under the two-phase attack, Putmans did not dare to fight hard.

Putsman asked some of the seriously injured and unable to retreat to continue the resistance, covering the retreat of the uninjured and lightly wounded mercenaries, promising heavy money to the families of those who remained, and swearing an oath.

In the end, the Netherlands lost one ship, killed 800 defenders, abandoned most of the supplies, and the rest retreated by ship.

The battle lasted 20 days, and the Ming army took Resha, completely expelling the enemy from the treasure island.

However, two large warships of the Ming Navy were sunk, and many Fu ships and Guangzhou ships were damaged to the point of almost being scrapped.

The Treasure Island was officially established as the Economic Strategy Mansion, and the South Juyi was the Treasure Island Economic Strategy. Pacify the population of the island.

For the potbelly kingdom, the toast is kept for 20 years, and then the land is changed and returned to the stream.

Greatly promote the island's agriculture and canned food industry, arrange the construction of military tun to stabilize the important ports and towns, accelerate the migration to the island, fruits, sugar, and seafood will be the development direction of the island's sideline industry, and slowly build the island's transportation.
