Although the Haihan military has mastered all kinds of military black technology, it is unrealistic to rely on a limited number of walkie-talkies to give timely command to the troops participating in the battle in such a field combat environment, and only combat units that serve as officers are qualified to use them. The means that can be used in real combat are still very primitive, and they can basically only rely on the signals sent by gongs, drums, brass trumpets, and flags to command the low-level combat units. Soon after Mushabai's order was given, the gong was sounded by the soldiers, and a new flag was raised on the flagpole behind the fort to inform the defenders of the forts along the coast to retreat.

As for how to retreat to the second line of defense in case the fort is lost, the Haihan defenders on the island have done relevant drills in advance, so although the battle situation is unfavorable and needs to retreat, they are not particularly panicked. The artillerymen on each battery immediately filled the chamber with the prepared gunpowder packs, drew out a long lead, and stuffed a few more shells in front of it, ready to destroy the shore defense guns on the gun emplacements when evacuating. However, these guns are all old guns from 167 to 168, and they are not very valuable, and it is certainly better to destroy them than to fall into the hands of the Dutch.

As for the unused gunpowder on the fort, it could not be wasted, and the soldiers carried most of it with their hands and shoulders, and if there were really anything that could not be taken away, they strung them together with fuses and destroyed them together. And the reserve company that was just added was ▲≥ ▲≥ ▲≥ ▲ ≥, and m.⊕.c△om was to provide cover for them and block the Dutch who were trying to chase and kill them.

It was a pity to destroy the fort that had taken dozens of days to build, but the situation of the war did not allow him to make another mistake, and no matter how reluctant he was, he could not leave these guns to the Dutch. With a loud bang, a puff of smoke rose from the first detonated battery, but to everyone's consternation, the first battery was not the place where the retreat had been completed, but the one that had been attacked by the Dutch in the first place.

In fact, even Mushaber had given up on sending troops to rescue the besieged battery, which had been completely surrounded by the Dutch landing force, and it was no longer realistic to try to free the people inside. Mushaber could only hope to find an opportunity to capture a few Dutchmen during the battle, and then bring his own back in the form of a prisoner exchange after the war.

However, the Haihan defenders on that fort were obviously not willing to be captured, which was indeed an unacceptable choice for the invincible Haihan militia, so when the surviving gunners retreated to the fort, they had already made up their minds to die with the enemy. Almost all of these soldiers are naturalized citizens of Annamite descent, and they have been constantly instilled in the consciousness that they are ready to be loyal to Haihan at any time during their service careers, and under repeated long-term brainwashing, almost everyone has the consciousness of dying on the battlefield, and surrendering and being captured has never been one of the options on the battlefield. What's more, according to the relevant policies of the Haihan Dynasty, if they die on the battlefield, not only will they be added a level of military merit by the Military Commission later, but all their immediate family members can be treated as if they were moved to Sanya to settle down - this is the life goal pursued by almost every naturalized Annan citizen.

At the last moment, several Haihan soldiers filled the gunpowder bag into the barrel of the gun, and then directly triggered the iron tube bomb with a pull fire pipe. The force of the explosion not only lifted the fort pier into the sky, but also became a mess within a radius of more than ten meters around the fort. At least more than a dozen Dutch soldiers were killed in the blast, and more than 20 others were wounded and lost the ability to continue fighting. This is undoubtedly a huge blow to the Dutch, who have just seen the hope of a turning point in the war.

The place where Mu Shabo was standing was still hundreds of meters away from the explosion site, but he still felt a slight tremor from the ground at that moment, but it was nothing compared to the shock in his heart. He never imagined that he would be able to witness such a scene of sacrifice on the battlefield, although these soldiers were not strictly Han Chinese, but when they had to make a choice, these people could really sacrifice their lives for the Haihan, the regime established by the Han people.

As the personnel of the other batteries were evacuated, explosions were heard on the shoreline, and one by one, the batteries were reduced to rubble in the explosion. The Dutch, also deterred by the previous explosion, did not rush to attack the other batteries when they saw that there was no opportunity, but quickly established a base in the port area where they had just landed, in order to meet the subsequent landings.

Mu Xiabai clenched his fists, silently looking at the place where the smoke and dust rose, and the battle intent in his heart was constantly rising. By now he had realized that it would be much more difficult to defend the island than the military had expected, and the Dutch were by no means as cautious as the military had expected, and there would be a vicious fight between the two sides. Looking at the Dutch fleet of ships in the harbor that were approaching the shore one after another, Mushaber secretly made up his mind to teach them a good lesson in the second line of defense.

Van Longen, who had just come ashore, was trembling and informing the two commanders of the damage on his side: "...... the 'Redhair' has been hit by at least ten shells, and now the hull of the ship has capsized, and more than half of the cargo on board has been saved. I have given the order to abandon ship, but fortunately most of the crew escaped safely, only six were killed, and three others were missing. The damage to the other ships was okay and not too bad. ”

When the battery exploded, Van Longen was climbing down from the rope net on the side of the ship, and he was almost frightened into the sea. This bombing made Van Longen still a little frightened at this time, although he didn't know what the battle situation was ahead, but looking at the corpses and wounded who were carried down, he could also expect the fierce battle.

"Mr. Van Longen, let your ship in the best condition vacate the cargo, and then return to Batavia at once, and report what happened here to the company!" Spikes roared. His head was tied with blood-soaked gauze, and his head had been caught by debris from the ship's planks during the artillery battle, but fortunately it was only a skin wound.

Spikes' anxiety at this time was also understandable, the first to rush ashore to attack the shore battery was his subordinates, and the opponent's battery, which was only defended by only a dozen people, caused at least four or five times the casualties to his troops. In order to lay down such a fort, he had already lost nearly a quarter of his troops, and this kind of battle damage was really difficult for him to accept.

"Mr. Spikes, don't panic!" Browwer was the calmest at this time, and after stopping Spikes, he turned to Van Longen and ordered: "In the battle just now, our two troop carriers were damaged in different ways, and now they have lost their ability to sail, we need your ship and the men and horses on board to join the operation!"

"Okay...... So what can I do?" Van Longen also knew that the current situation was not the time for him to bargain, and that in wartime he had to rely on the orders of the military personnel, even if the other side wanted to requisition his ships and manpower.

"I want you to send a ship in good condition to the sea at once and give us an early warning on the periphery. Brouwer ordered Van Longen: "Also, let all the men in your fleet who have combat experience disembark and land, and we will issue weapons to them!

Van Longen hesitated and asked, "Fight these guys with us...... Is it really a pirate?"

From what Van Longen had seen and heard in the Far East over the years, it was hard for him to believe that any pirate had such a powerful firepower and could effectively organize a collective artillery bombardment. Including the eighteen Zhi, who used to be invincible on the southeast coast of the Ming Dynasty, it was just that there were many people, and the weaponry and combat efficiency were far inferior to this opponent. Van Longen had a vague feeling that it was not the typical rabble that was fighting against his family, but a force with a certain level of military literacy—a group of men who had at least received formal combat training.

"It's supposed to be a pirate. Brouwer replied with a gloomy face: "I checked a few corpses just now, and judging from their faces, figures, and clothing, they should all be from Annam. Coupled with the Nguyen banner they played, I think it is very likely that it is the people of southern Annam. It's a pity that our people haven't been able to catch them alive yet, so there's no way to determine their identities for the time being. ”

The militia troops stationed on Ambuna Island had all changed their outfits before they were deployed, and all the soldiers knew what they were playing here, and their composition was originally composed of soldiers of Annamite origin, so it was very easy to play the role of the remnants of the Nguyen clan who were in exile. The Dutch wanted to find clues about their identities from the bodies of their fallen soldiers, and they could only point to the one that had been designed in advance.

"The combat ability of the Annan people is so strong!" Fan Longen sighed, but after thinking about it, he felt that this evaluation was really inappropriate, and quickly added: "Of course, it is still not as powerful as our soldiers!"

Brouwer stared at him and replied coldly: "I heard that the Portuguese trained a firearms army for them at the beginning, this is probably the result of the Portuguese!"

Brauvau's knowledge was indeed correct, and the southern Nguyen Thi controlled zhì at the beginning, relying on the firearms units trained for him by the Portuguese, even had an advantage in the civil war between the north and the south for a time. When Haihan intervened militarily in the civil war in Annam, the northern army had already been routed to the north of the Hengshan Zhengjiang defense line and fell into great passivity. However, what Brouwer didn't know was that the army trained by the Portuguese was still more than a grade worse than the Haihan militia, and it had long been exhausted in the following battles.

Van Longen did not dare to answer again, and hurriedly turned back to arrange his own fleet. At least one or two hundred men on his seven ships had been on the battlefield, and it was not a big problem to organize one or two companies of militia on the fly.

Spikes finally calmed down at this time, looked at the ruins of the fort on the shore and said, "Their troops are insufficient, so if we break through one place, we can only choose to abandon the entire defense line and retreat inland." ”

"I just hope they don't have time to build a second line of defense, and if they build so many batteries inland, it won't be optimistic. "Brower is not optimistic about the future of the operation.

"With the combat power of these people, it is not surprising that they can take this island. But what's the use of them taking this place? there's nothing to be gained in this place!" Spikes wondered, "Come to think of it, if they just want to plunder this place, then there's no need to build forts and fortifications on the island, and if not, what's the point of taking this place?"

"Perhaps their purpose is to rob our merchant ships in this place. Brouwer raised his hand and pointed to the three merchant ships belonging to the East India Company on the shore and said, "If I am not mistaken, these ships were probably captured by them after they sailed into the harbor, otherwise they could not have been so intact." I've had people go over to check on the condition of these ships, and if it's normal, I'll send someone to drive one of them back to Batavia to report the news, so that there is no need for Van Longen's ship to be unloaded here. ”

"Or you're thinking about it. Despite his opinion of Brower as a person, Spikes graciously acknowledges the other's strengths. At least being able to keep a cool head in the current battle situation is a must-have for a good commander.

However, Brouwer was well thought out, but reality quickly disappointed them. The men sent to inspect the three merchant ships returned to report that the tail rudders of all three ships had been damaged and could not be repaired at least for the next few days.

"There's no way, we have to requisition Van Longen's ship. Brouwer had no better idea of the outcome than to have Van Longen inform him and have his ship unload here first, and then rush back with an empty ship to report the news.

The communication efficiency of the Dutch was naturally not comparable to that of the Haihan side, and while withdrawing to the second line of defense, Mushabai used the radio to send telegrams to both the base camp and the Annam Military Region, informing them of the current situation and requesting support.

After the previous battle, Mushaber already knew that with the strength of the island's defenders alone, he might not be able to compete with the Dutch for a long time. Even if they can repel the Dutch attack this time, it is likely that it will not be long before they make a comeback. The island's arms reserves are limited, and after a few more battles, it is estimated that the ammunition will gradually become overstretched. It was a long way from the base camp and Annam, and given the time it would take for reinforcements and supplies to travel on the way, Mushabai had to ask his superiors for help in advance.

However, even if the reinforcements arrived from Cam Ranh Harbor, the closest to the Ambuna Islands, it was a 500-nautical-mile voyage, which could not be reached in three or two days, and until then Mushabai would have to rely on the island's defenses to resist the Dutch attack. What he is most worried about now is not whether he can withstand this wave, but whether the Dutch will have a follow-up fleet to set up an ambush at sea to encircle and reinforce.
