Under the city of Geransha, the sound of cannons is incessant all day long.

A large number of Zheng troops converged into Dayuan Town, and then quickly spread to the castle of Geranza.

The Dutch are not going to sit still.

The inner city corresponds to the Cambeyufei Fort and the Fort of Frixinlian on the side of Dayuan Town, and one cannon after another bombarded Zheng Jun, and even piled up several heavy cannons on the semicircular fort in the center of the second-layer platform in the inner city, and fired at Dayuan Town from a distance.

As mentioned above, although the castle of Geranza is divided into two cities, the two cities are spliced together, rather than the outer city on the outside of the inner city.

The location is in the southwesternmost corner of the entire sandbar in the outer city, where the Dutch authorities and merchant houses are located. At the same time, it corresponds to Dayuan Port, and the northern line of Oshima on the opposite shore restricts the access to Dawan. A cannon directly blocked the sea, not to mention the narrow "place" between the sea under the city.

Therefore, even if the height of the outer city is very low, it is roughly similar to the first floor of the inner city. Compared to the three-storey inner city, this is definitely an obvious flaw in the city of Geranza. However, the unique geography makes up for this shortcoming, especially as the Dutch navy still controls the surrounding seas.

Therefore, the only way to attack the castle of Geranza from the town of Dayuan is to withstand the attacks of Fort Cambey and Fort Frecinlian.

In this environment, the Dutch, who were condescending and protected by a castle, should not take advantage of them too much, even though the number of artillery on their forts was far less than that of the Zheng army outside the city.

If the Zheng army wants to shell the city of Gelanza, it must move forward under artillery fire and transport one artillery cannon after another. But this kind of thing that obviously has to suffer, Zheng Zhilong will not do it.

At least don't struggle, regardless of whether the method you come up with is useful, try it first.

He wouldn't do it until the one he came up with proved unworkable.

He doesn't lack time, does he?

Ditches start from the edge of Dayuan Town, only three feet wide and one person high, first in a straight line and then in an "S" line.

When it was only 100 zhang away from the castle, he began to set up gun emplacements. The large circles with a diameter of two zhang and the depth are much shallower, and they look like beads worn on thin threads, but they can accommodate the next artillery to hide.

The excavation was piled up in front, adding a solid layer of protection to the gun emplacement, leaving only the direction the muzzle pointing, three feet wide, enough for the gun position to fire.

It was the first time that the Dutch had seen trench warfare, and at first they didn't know why, but they felt threatened when they saw that the excavation inside was quickly turned into a thick mound on the ground by Zheng Jun. Of course, they will not tolerate Zheng Jun's large-scale excavation, and send people to sabotage many times day and night.

The casualties caused by the shelling on both sides are actually less than half the number of casualties on both sides in such sabotage warfare.

At the earliest, in order to prevent the enemy from being raided by the enemy day and night, the Zheng army not only arranged a large number of soldiers to be on duty at night, but also took out barbed wire. Wrap a mound of earth into a small square, which doesn't need to be too high, but it must be thick enough to withstand the shelling. Then wrap three or two barbed wire fences around the perimeter like a footcloth, and then add the thistles sprinkled on the ground, only a dozen or twenty people need to be stationed, with two tiger squatting cannons and a large number of grenades, which is enough to make the Dutch hesitate several times ten times over!

- There's no way they're going to take a stronghold like this quickly. No matter how many of them there are!

And if you can't take this front stronghold, even if you bypass it, you will only fall into Zheng Jun's front and rear crossfire, and there are guns coming from all directions, and they will cry and cry and doubt their lives.

The Dutch confirmed this with bloody reality.

Therefore, now when looking at the Zheng army strongholds in the castle of Geranza, which seem to be very simple and simple, the Dutch in the city have no headache.

That's the same as Zheng Hongkui in Penghu and Putmans in Dayuangang.

Both of them are anxious to take the lead in breaking the enemy, but in fact, neither Zheng Zhilong nor Paul put pressure on them.

The two of them know very well that they are absolute laymen in naval warfare, but Zheng Hongkui and Putmans are absolute experts, so in this case, they naturally leave professional things to the right experts to do.

But there is no pressure on the outside, Zheng Hongkui and Putmans are very good at adding inner drama to themselves.

Because of Zheng Zhilong's smooth progress on land, both of them had a sense of urgency, looking forward to getting their opponents in a short period of time.

This one is to keep up with his eldest brother; One is to prove one's abilities to the company.

But how easy is that?

Now is not the time for Zheng Zhilong to go to Taoyuan, after the time enters the middle of July, it is already a time when storms in the Taiwan Strait are frequent, a month, half a month of high winds and waves, and the fleet cannot go to sea at all.

If the two sides want to fight, they also need to avoid this period of time first.

The original battle of Liuluo Bay also began at the beginning of the sixth month of the lunar calendar, and it was only in September that the battle was won.

The two armies fought each other on a small scale many times, and the Dutch also went to Copper Mountain many times to escape the storm, and some warships were blown away from the fleet by the storm......

And now, the geography between Penghu and the south of the island is very different from the tortuous and complex geographical environment of Fujian, in Fujian, the Dutch can also break into the Tongshan sea area to escape the storm, Nanao, Haicheng, Chaoyang, they are all natural shelters from the wind and waves. And all in Xiamen, south of Kinmen.

But what about between Penghu and the south of the island?

In the vast sea, there are only a few small sandbanks.

But unlike the southeast, at this time on Juehua Island, the defenders have begun to prepare for intense battles before winter.

With last year's experience, the soldiers on the island, and even some businessmen who are preparing to stay for the New Year, do not feel too nervous.

From the population review of Liudao to the reserve of food and materials, and then the arrangement of the troops and soldiers of various ministries, Zheng Zhibao did everything in an orderly manner. Zheng Sen looked at Juehua Island, which was gradually left behind by the ships, and his heart was filled with a few wisps of reluctance......

He learned a lot here, realized the hardships of refugees, and learned about the many tricks in the bereavement and relief work, the darkness of society, and the darkness in the army, which made people tremble. He also saw clearly the filthiness and shamelessness of the civil officials, and of course, the military attaches of the Ming Dynasty were not far behind.

Therefore, Zheng Sen clearly recognized what his father said about the Ming Dynasty's "foundation has rotten".

Compared to him two years ago, he is much more mature.

A manly man, he can't be a tool if he doesn't grind. Compared with Zheng Chenggong, who had a low eye in the original time and space, he now knows what forbearance is, what helplessness is, and what is said and done, and one thing in front of him and another behind his back.

Life is not as good as it should be, and Yanghu's sentence is really not wrong.

Even if Zheng Jun's status in the Ming army outside the Guanwai is already quite high, but under the banner of 'Daming', how can some dirty things stay out of the matter?

You must know that Zheng Jun is still a weapon used by Fan Zhiwan and Qiu Minyang to suppress Wu Sangui. And Zheng Zhilong considered the overall situation, and also instructed the two to fully cooperate with Fan Zhiwan and Qiu Minyang.

Thinking of those bullshit things within the Ming army, Zheng Sen was depressed and panicked, but it was in this depression that his whole person gradually grew up. This is the mental journey that Zheng Chenggong of the original time and space can never experience.
