More than 2,000 pirate prisoners were divided into two shifts. Under the supervision of supervisors and engineers, a trench was dug in just two days. Infantry and artillery protected the fortifications to prevent pirates in the fortress from leaving the city to attack.

Pashamurat personally led his men to the basin to observe the enemies who were acting abnormally outside. He was puzzled by the dusty construction site outside. He didn't know why the coalition forces outside the city wanted to build a large-scale construction.

"Are they planning to siege our fortress for a long time?" Murat always felt that the other party's actions were full of weirdness.

The pirate leaders hid in the fortress looked around and the trenches dug out by the siege were about 1,000 meters away from the bastion. With such a long distance and the protection of the trenches, the artillery in the fortress could not pose an effective threat to the pirates in the trenches and infantry and artillery deployed behind the trenches.

"They seized Algiers and could get supplies from the city and nearby tribes. If they wanted, they could indeed siege us for a long time until we exhausted our troops. Lord Pasha, since they were not willing to withdraw their troops, it means they were fully sure to break through the fortress." The pirate general Amur limped behind Murat.

During the battle, he was ambushed by a surprise attack team led by Sun Chuanting. Stream bullets rubbed past his legs and almost smashed his entire thigh.

As a terrifying pirate general, he was fearless in the Western Mediterranean and even dared to steal the Spanish Navy's galloping boats. However, in front of the tripartite coalition led by the Chinese, he was defeated again and again.

He led the pirates to seize the stranded frigate, protect the fort, and return to the city to help. He was worthy of Pasha's trust in him, but in the face of absolute strength, no brave battle could make up for the gap between the two sides.

He lost his courage as always, and wanted to let this group of devils from the East and the annoying Europeans leave them Algiers as soon as possible.

The other pirate leaders also had the idea of ​​sending the plague god. Their war-weariness affected Pasha, who was the supreme ruler.

"We will hold peace talks with them again, and are willing to pay 200,000 taels of silver to compensate, and let them take the hostages away!" Murat was a little hysterical.

From the fortress he could overlook the messy Algiers town, most of the houses were looted and black smoke was rolling.

It can be said that after this battle, Algiers suffered an unprecedented blow, and his prestige and the Ottoman Empire here plummeted. In the future, Europeans would not give them face, and even refused to pay protection fees for them.

The pirates trapped in the fortress wanted to negotiate again, but Sun Chuanting and others were determined to capture the Fortress of Penion unless the pirates could hand over a 1 million taels of silver that satisfies them.

The members of the Royal British Fleet and the Knights of Malta obtained a lot of wealth by looting pirates and capturing pirate ships. They were very satisfied with the expedition and thought about leaving.

However, Sun Chuanting was unwilling to let this group of people go, their warships and soldiers still had a role.

So they promised that if the pirates pay compensation, the Chinese who were responsible for the main task of attacking could get 70% of the compensation, the British divided the 20% and the Knights of the Malta. That is to say, if the pirates compensated 1 million taels of silver, the minimum Knights of the Malta could also get 100,000 taels of silver.

The Knights of Malta arrived this time, with about 800 members, each of whom could get more than 100 taels of silver. In addition to the wealth obtained by looting pirates, the money could allow them to buy several large ships.

"When the Netherlands attacked the bastion, they would completely concentrate their siege firepower in one place, open a passage, and then organize infantry to charge from here. The cost is often heavy, but only in this way can we avoid the long siege." Sir Greenville has long led the English Expeditionary Force to be active in the Netherlands battlefield and is most familiar with the Netherlands' tactics.

At this time, the Netherlands, Sweden, took military changes due to its participation in the Thirty Years' War on the Continental region. All British officers active in the battlefield of the Netherlands highly praised the tactics of the Netherlands.

Of course, this was the idea before they came into contact with the Chinese. After they came into contact with the Chinese, their military ideas had to undergo a greater change.

"We cannot joke about the lives of soldiers. They finally came here from the east, thousands of miles away, to fight. There are still family members waiting for them to go back in their hometown, and using the lives of soldiers to exchange for compensation. Such a transaction is really not cost-effective." Sun Chuanting gestured the distance between the fortifications on paper, and magical things like standard rulers and pencils appeared in his hands.

Sir Greenville came over and saw the fortifications of the attacking the fortress. He saw a trench close to the trench, three trenches parallel to the fortress, and four trenches connected in zigzag shapes, and the parallel trench at the front was almost tightly attached to the prism.

Sir Greenville, who had discussed with the Netherlands generals on the battlefield, saw a little trick.

"You want to dig the approaching trenches, carry out civil engineering operations from the trenches forward, approach the fortress in a zigzag shape, and then dig the first parallel trenches to consolidate the defense line, continue to advance in the same way, and finally arrive at the bottom of the fortress to attack..." Sir Greenville exclaimed after seeing it clearly.

"Yes, when the engineers push the trench below the fortress, our engineers will use artillery fire and explosives to open the breakthrough. When our fortifications advance to the fortress, it will be the day to break through the fortress." Sun Chuanting said.

There is nothing to hide from the new siege tactics. They often surprise everyone when they are used for the first time, and then everyone will imitate them.

"Amazing tactics! The Netherlands will also use the method of digging tunnels to push cannons and infantry under the enemy's noses, but they absolutely have no such systematic plan!" Sir Greenville was deeply shocked when he saw Sun Chuanting's idea.

"Isn't this a very normal method of siege?" Sun Chuanting didn't think there was anything, because the parallel siege method invented by the French was already a common sense that all army officers must know in the army martial arts hall in the capital.

He hadn't realized that the Frenchman who used this systematic method to attack the fortress for the first time was still a little brat!

"I learned a lot from you. If I were still young, I could still try this tactic in the Netherlands battlefield. Unfortunately, I have even a granddaughter now." Sir Greenville sighed.

The pirates saw two zigzag trenches extending in parallel trenches. After 2,000 pirates took turns to dig, they quickly approached the fortress. They began to realize Sun Chuanting and others' intentions to fight.

"Concentrate artillery to bombard their trenches, and they cannot get close to the bastion!" Murat was anxious when he learned that the offensive and defensive parties were approaching quickly.

Ten bronze cannons that were approaching the trench and zigzag trench began to bombard the shelling, but this did not cause much obstacle to the rapidly advancing trench. The 10 cannons on the front of the bastion can only kill a few pirates who dug the trench every day, and this loss is nothing for 2,000 pirate prisoners.
