After the fall of Fort San Diego, the Ming military flag fluttering high on the castle tower fell not only into the eyes of the Dutchman Hans-Putmans, but also in the eyes of Zheng Ming, the deputy general of the Zheng Army's naval division, who was blockading the island of Sheliao, and Bidno, the senior commercial representative of the Dutch East India Company.

At the same time, the Ming military flag fluttering high on the tower of the castle of San Diego also fell into the eyes of Sebastián Camanda, the commander of the city of San Salvador.

Since the siege of the island, the ships of the Spaniards were either captured by the Dutch and Zheng Jun's sailors, or they were blocked in the port of the island, unable to rescue the cities of San Lorenzo, Santo Domingo, or the nearby Fort San Diego.

Like the Dutch East India Company of this era, the Spaniards had a large colonial empire, but because they had so many colonies, they were able to send only a handful of warships to Luzon, especially Formosa.

The already small number of large warships were assigned to San Salvador, San Lorenzo and San Diego.

Now the two main warships docked in San Lorenzo have been destroyed by the Dutch, and the main warships docked in the nearby Jonjiro Port under Fort San Diego have also sunk to the bottom of the sea in the artillery battle that lasted for more than half a month.

The two main warships left in the city of San Salvador have now been captured by Zheng Ming's naval division under the command of Zheng Ming, and the Luzon natives who were carrying the troops who went to support Santo Domingo have also been taken prisoner, and the other has stopped in the harbor and has been wounded by the Dutch naval guns, and now does not dare to leave the port.

Not long after the Dutch sailed north from Batavia with five main warships, Sebastian, the commander-in-chief of the Spanish colonial forces in Formosa stationed in San Salvador, received a warning letter from Manila.

The Spanish governor in Manila sent a letter to him from the Spanish merchant ships heading north, telling him to be wary of the Dutch.

Especially because of the rare incident of Ming envoys going to Batavia, the Spanish Governor's Palace in Manila also reminded Sebastian to beware of the possibility that the Dutch might join forces with Zheng Zhilong, who had submitted to the Ming court, to launch an attack on the Spaniards.

Therefore, Sebastian is prepared for the situation he may face.

It's just that Sebastian, who has always been invincible in the West Indies and Luzon, did not expect that the Spanish colonial army under his command, as well as so many native soldiers in Luzon, would be defeated so quickly.

Do the math, it has been less than a month since Zheng Zhilong swore to go north in his base camp Beigang.

Ever since the Dutch ships appeared outside the port of Fort San Diego, Sebastian's mood was unusually heavy.

This suggests that the city of San Lorenzo, on the east coast of Formosa, may have been lost.

And as a veteran colonial commander who participated in the conquest of countless countries, Sebastian was superior to the Spanish until the Dutch were outfit.

Otherwise, he would have gone straight to the Dutch's territory, and would not have come to the north and east of the Formosa Mountains to build a city.

On the morning of September 18, the dragon and phoenix dancing military flags fluttering above the castle of San Diego made Sebastian's mood fall into a trough.

Because the fall of San Diego meant not only the loss of the city of San Lorenzo, but also the loss of the castle of Santo Domingo.

In the early morning of 19 September, when Sebastian's mood was at an unprecedented low point, Bidno, who was determined to win the city of San Salvador on Sheliao Island, ordered the Dutch mercenaries to take advantage of the rising tide of the sea to rush onto the shore of Sheliao Island and fight fiercely with the Spanish colonial troops who had heard the news on the open beach in the northeast of Sheliao Island.

More than 1,200 Dutch mercenaries landed on the beach and repelled the defensive line hastily set up by the Spanish colonial army on the beach.

If it weren't for the dense and sharp artillery on the head of San Salvador, perhaps the Dutch would have been able to storm the city in one fell swoop.

By noon that day, the dust had settled.

With 231 casualties, the Dutch besieged the Spanish colonial army and the Luzon native soldiers on the island in the city of San Salvador.

The Spanish colonial army and its two servant troops, native soldiers from Luzon, left behind more than 300 corpses of Spaniards and more than 500 native soldiers of Luzon on the beaches of Slao Island and under the city of San Salvador.

In the evening of the same day, after counting the casualties and losses, Sebastian received a letter of surrender from Biedno on behalf of the Dutch East India Company.

Along with the persuasion of the new surrenderers, Antonio, the commander of the Castle of Santo Domingo, the half-rotten head of González, the commander of the Castle of San Lorenzo, and the fresh head of Fernando, the commander of the Castle of San Diego, were still well preserved.

Soon, by the morning of the next day, Sebastian, who had been thinking bitterly for a night, made the choice that Westerners would almost always make in such a situation.

On behalf of the Dutch East India Company, Bidno promised Sebastian and the Spanish Merchant Pavilion in the Castle of San Salvador and his dependents that as long as Sebastian and the Spanish colonial army in the city surrendered and disarmed, Bidno and the Zheng Junshui who were roaming nearby agreed to the safe departure of Sebastian and the Spaniards in the city.

The Spanish warships anchored in the harbor remained in the possession of the Spaniards after they were disarmed, and the Spanish warships captured by Zheng's sailors were redeemed by the Spaniards with all the property in the city after they were disarmed.

At noon on the same day, Sebastian led the Spanish colonial army in the city of San Salvador, as well as more than 700 Spanish merchants and their dependents, to board two disarmed Spanish warships and leave the island.

The city of San Salvatore officially passed into the hands of the Dutch.

The weapons, ammunition, gold and silver goods and other materials that were not taken away from the city of San Salvador, as well as the Luzon native soldiers and indigenous Luzon women who were left as property, totaling more than 400 people, were transferred to Zheng Zhilong.

Zheng Zhilong's clan brothers Zheng Cai and Zheng Lian, on the second day after they took Fort San Diego, went to Zheng Zhilong for a secret talk, suggesting that they take advantage of the gathering of the army to directly turn their faces and kill the Dutch.

And Zheng Zhilong himself also thought about whether to eat black and black, and take advantage of the opportunity when his main force gathered, and simply kill the main force of the Dutch in one fell swoop.

But after thinking about it, I still feel that it is more important to go back to rescue the coastal areas of southern Fujian and clean up the losses and chaos caused to him by Liu Xiang and others.

Although Zheng Zhilong gave up the idea of killing the Dutch in black, when San Salvador was already destined to be taken, Biedno and Putmans also paid attention.

In particular, Waite, the commercial charge d'affaires of the Dutch East India Company, who is well versed in Zheng Zhilong's various methods, is always paying attention to Zheng Zhilong's every move.

If this is not the case, this time the Spaniards will not even have scum left on Dongfan Island.

In this way, the Spanish colonial army, which originally held out in the northern part of Dongfan Island until the fourteenth year of Chongzhen, was forcibly terminated in this life, when their colonial development on Dongfan Island had just begun.

Zheng Zhilong, the boss of the Zheng family on Dongfan, and Bideno, the senior representative of the Dutch East India Company, also divided the sphere of influence of the two sides on Dongfan Island according to the previous agreement.

The Dutch East India Company recognized Zheng Zhilong, the commander of the Dongfanwei as the commander of the Dongfanwei on behalf of the Ming court, the ownership of the main island of Dongfandao and its western and northern annexes.

At the same time, Zheng Zhilong, on behalf of the Ming court, also accepted the ownership of the Dutch East India Company to Fort Rebar, as well as the lease of the city of San Lorenzo and its port, the city of San Salvador and the island and port where it was located.

On the morning of 21 September, the two sides, each with their own intentions or ghosts, signed a final agreement in Chinese and Dutch on a Zheng warship outside the port that Zheng Zhilong had changed to Keelung Port.

In this agreement, the city of Santo Domingo was renamed Tamsui City, and the city of San Diego was renamed Keelung City, which was also called Tamsui Red Hair City and Keelung Red Hair City respectively.

The cities of San Salvatore and San Lorenzo, which were transferred to Dutch possession, are still old.

Without the common enemy of the Spaniards, the relationship between the Dutch East India Company and Zheng Zhilong immediately became delicate.

When the previously agreed agreement was finally signed before the mutual change, the two sides, who were wary of each other, immediately returned to their respective spheres of influence.

Zheng Zhilong left his clan brother and confidant Zheng Cai, with 2,000 Zheng troops, using the cannons dismantled from the captured Spanish warships and the guns and ammunition collected in the city of San Alvado, Keelung Port and Keelung Hongmao City in Keelung Port were quickly armed.

At the same time, Zheng Zhilong asked Zheng Ming to take the sailor by sea, and he took the infantry by land, and began to return to Beigang, his base camp on Dongfan Island, ready to return to southern Fujian.
