No accumulation of steps, no thousands of miles. Zheng Zhilong's plan is very good, but it must be implemented step by step.

He must now use the power of the army to put more pressure on the city of Geranza in order to create better conditions for the upcoming naval battle.

Cannonballs rained down on the castle of Geranza.

Whether it is Fort Frecinlian or Fort Camberfair, or the semi-circular fort between the two forts, they are like red-hot iron ingots, constantly being smashed by heavy hammers (cannonballs).

Every solid shell landed with a loud bang.

"Open fire—" To the east of the castle of Geranza, in the large open space between it and the town of Dayuan, there were artillery emplacements dotted between the winding trenches, and in the face of the Dutch return fire from the city, the gunner's face did not move at all, and his voice was as calm as a mountain, and the shells did not seem to hit his heart at all.

After all, it's night. It was difficult for the Dutch to smash shells into gun emplacements during the day, let alone at night.

They don't pay attention to the speed of these gun positions, and they come slowly in the black light, and the shells are connected to the butt and the powder packet, which greatly saves the steps in loading. Occasionally, an open flame is lit, but it is also lost in an instant. The Dutch were not given a chance to aim at all.

What's more, both sides are front-loading smoothbore guns, and the accuracy is poor.

"Whoosh-" A bright light slanted through the battlefield, illuminating the entire sky. It was already night, and Zheng Zhilong had an order - it was necessary to ensure that there were flares in the air every quarter of an hour.

This kind of old-style fireworks product, Zheng Zhilong has prepared not too much!

Looking at the flares shining in the sky, a trace of disgust flashed in Paul's eyes, such a ghost ...... is all the cleverness of the Oriental!

But he couldn't deny that with this kind of thing, how to send soldiers to sneak attack in the castle to deal with those damn artillery must be a lot of trouble.

Fort Frecinlian and Fort Camberfair have been bombarded for many days, and it is not known how many shells have hit them these days, even though they are so strong that they are difficult to destroy with solid shells. But one by one, the iron balls fell on the castle, and the gun emplacements on the two fortresses and the semi-circular fort in the middle of them were greatly affected.

Compared to the number of artillery pieces that the Dutch could place on the city, Zheng's army had too much artillery fire.

One of the five or even ten shells hit the fort, which was a great threat to the gun emplacements on the castle.

Because in this era, the gun emplacements were all open-air, at least that's how the castle of Geranza was arranged.

Therefore, even if there will be a certain loss, in the dark night, he will send soldiers out of the city from time to time to sneak attack. Because compared to the attack in the daytime, at this time they are the most threatening and the least threatened.

The soldiers didn't need to get into the gun emplacements in the trenches, they just had to throw grenades far into the gun emplacements.

Today is the time for the night battle again, and hundreds of Dutch soldiers and a group of aborigines (patrols) begin the attack tonight.

Another flare was fired, and in the moment of the shining light, the figure of a Dutch soldier under the black pressure below was revealed.

"Boom ......"

There is no need for any further orders from the commander-in-chief. The musketeers, snipers, and even a large number of rattan soldiers, who had long been stationed in the trenches, began to attack.

Immediately in the darkness of the night, heavy gunfire rang out, and heavy figures flickered at the front of the position.

"Boom, boom, boom ......" a dense explosion, but much weaker than the sound of shells, exploded in front of the position.

This is a grenadier confrontation!

Seriously. The Zheng army under the city made Paul almost forget what the soldiers of the Ming Kingdom looked like in his previous memory. When he followed Colonel Reyes Zorn to fight with the Ming army in Penghu, the Ming soldiers at that time and the Zheng army in front of him were really two completely different armies.

Grenade throwing in trench warfare is brutal. The fixed environment makes it difficult for people to escape in time even if they find that the grenade has fallen under their feet.

The power of the latter is not large, but the range of damage is absolutely fatal to the soldiers on both sides of the trench.

The Dutch soldiers who rushed to the front were immediately inflicted, and the Zheng army threw hundreds of grenades together, far outnumbering them, and the power of the explosion was enough for the Dutch to write off their vanguard on the spot.

More than a dozen men fell in the trenches, and muskets rang out.

However, the Dutch soldiers, who had been killed and wounded, still shouted mixed cries such as "Gates" and "Tired", and charged the forward positions. They naturally become magnets, attracting all the firepower. Booming grenades continued to fall in the crowds of soldiers on both sides, stumps and severed arms stained the battlefield with blood, and fragmented corpses were scattered everywhere along with broken hot and cold weapons.

Paul's fingernails were to be fastened into his flesh. The loss of the soldier made his face turn blue and his heart bleed.

However, "every soldier's life is precious and cannot be wasted." ”

With a wave of his hand, Paul ordered, "The follow-up troops will follow." Burst in for me. ”

Man, already dead. Then let their deaths make more meaningful.

So Paul did not withdraw his troops, but increased them.

Another hundred men joined in, and not surprisingly, the Dutch took the most advanced position under the city of Geranza during the night. However, due to the attack of grenades and muskets, the attacking Dutch soldiers suffered as many as thirty or fifty casualties, while the Zheng army in the defensive posture suffered very little losses.

Even if the Dutch threw grenades into multiple gun emplacements and detonated the powder barrels in the gun emplacements, they would have lost a few guns at most.

But how many Dutch soldiers were there in the city? With so many losses in one sneak attack, they themselves can't afford to take it a few more times.

In fact, the Dutch in the city had a headache in their heads.

If you don't pull out these nails that are close at hand, the cannonballs will cover the entire castle. But if you want to remove it, the loss is too great, so it's not a headache.

Of course, the Dutch also learned some tricks from this war. Like trenches.

Compared with the straight tunnel trenches that the Europeans would also have, Zheng Jun's curved trenches and anti-artillery holes and other facilities, the effectiveness is definitely beyond their era.

Paul once suddenly realized to the "anti-artillery hole" that with the curved trenches and anti-artillery holes, his counterattack all day and day long could not defeat many Zheng soldiers.

But none of this has any effect on the castle of Geranza now. Unless Paul was willing to fight in the streets after the city was broken, that was not possible!

……

Dozens of wounded people are being treated in hospitals in the city of Geranza. Zhang Dejin bypassed the edge of the hospital bed, and near the door, the bed area that could bask in the sun was full of seriously injured people. For example, now, the three people lying here are all unlucky people who have just had an amputation and are missing a leg or an arm.

Two of the three were groaning crookedly, and one was silently weeping. Without arms and legs, even if they can survive in the future, they are useless waste.

Zhang Dejin doesn't pity them, and he doesn't feel that they are really pitiful.

First of all, he is a citizen of the Ming Dynasty, although his medical skills are not good, but he usually practices medicine in the south of the island, but he has also made some fame in this place. So he was captured by the Dutch and caught in Geranza.

If the Dutch hadn't forced him with his family, he wouldn't have been in Geranza at all.

Again, Zhang Dejin felt that their (the wounded soldiers') luck was good enough. After many years of mixing in the south of the island, Zhang Dejin has heard of the medical skills of the West and the treatment of these soldiers when they fight.

If this is in the West, even if an officer is so seriously injured, it is still two to say whether he can be taken care of as well as he is now. The few red-haired creeps at the moment are definitely lucky enough!
