In Laizhou Bay, Zhu Yihai was looking at the drawings. Not far away, the seaside was bustling with activity, and many hungry people gathered there because the Ming army was giving out rice porridge.
After finishing the porridge, he followed the arrangement and helped build the water village.
The drawings drawn by Zhu Yihai himself planned to build a water fortress at the mouth of the Yeshui River in Laizhou Bay, just like the Fucheng of Dengzhou is one prefecture and two cities. The Fucheng is both the county seat and the acropolis, and there is also a Penglai water city.
Compared with the two cities in Dengzhou, Laizhou's prefecture, Ye County, is still more than ten miles away from the seaside. On the banks of the Ye River, Zhu Yihai planned to defend Denglai as a base for the Northern Expedition. Laizhou's city defense seemed monotonous, so he planned to imitate Penglai at the mouth of the Ye River.
Water City also builds a water fortress.
However, the location here is not as good as that of Penglai Water City. It is impossible to surround a small sea in the water city, and there is no protruding mountain to guard the high ground.
However, the Ming army had a water advantage, so water fortification was still feasible.
There is no need to make it too complicated. Zhu Yihai's drawing shows a simple seaside bastion fortress. In order to cope with the siege of the Qing army, especially to prevent artillery, the bastion has been popular in Europe for many years. It is actually a very good one.
choose.
Compared with traditional Chinese-style cities, the biggest difference between bastions and fortresses is that they highlight the defensive performance of military fortresses. They are not suitable as a city that integrates residential and market transactions, but they have strong defensive performance as a military fortress.
It is particularly outstanding in dealing with artillery.
The bastion has sharp edges and corners, and its biggest feature is its triangular bastion and half-moon bastion, which can form crossfires and achieve no blind spots for firepower.
A simple pentagonal bastion can provide the best shooting angle on each front and city wall. Each corner has a strong bastion extending out, ensuring the most basic fire coverage requirements while meeting the minimum amount of construction.
.
The bastion mainly relied on artillery to defend itself against the enemy.
Zhu Yihai's pentagonal fortress was built at the mouth of the Yehe River, with the river on one side and the sea on the other. The terrain is like a protruding triangle.
The bastion was built here and was blessed by nature.
Combined with earth slopes, trenches, and peripheral half-moon forts, it can also form a three-dimensional defense.
A pentagonal main bastion city, plus the five peripheral triangular bastions, and two trench embankments, is equivalent to having ten fortresses, with cross-cutting fire coverage.
At this stage, the Qing army's red artillery, even heavy artillery weighing six to seven thousand kilograms, is difficult to effectively destroy the city wall.
It can station a lot of soldiers and set up many artillery, which is easy to defend and difficult to attack. The problem is that this kind of bastion is actually not difficult to repair. It can even be simply surrounded by wooden piles on the outside and filled with soil on the inside.
Now Zhu Yihai set up a porridge shed, and countless hungry people came. Each person drank two bowls of porridge, and then they could start to help with the work.
In order to give full play to the advantages of the navy, Zhu Yihai also designed docks on both sides of the river and sea of the fortress, and even built a wooden floating city platform on the sea.
"His Majesty."
Chen Qianfu, the general general of the imperial camp, came to pay his respects and said, "Boluo is marching north from Xuzhou with 10,000 troops."
"Which way did you go?"
Zhu Yihai asked the guard to get a map.
"From Xuzhou to Yizhou, it seems that we have to pass through Yishui River and cross Muling Pass to Qingzhou."
Zhu Yihai compared the map and found that this was one of the four main routes in Shandong. Liu Yu passed through this route when he was on his northern expedition to destroy Yan. The advantage of this route was that it was relatively close, but the disadvantage was that it had to cross the Daxian Mountains.
The State of Qi once built the Qi Great Wall in Shandong, and Muling Pass was known as the most powerful pass in the world at that time.
The Qi Great Wall winds for thousands of miles, starting from Pingyin in the west to Langyatai in the east. Muling Pass guards the dangerous pass. During the Jiajing period of the Ming Dynasty, the pass tower was renovated and a stone tablet was erected.
"The advantage of Boluo's urgent troops heading north is to fight quickly. I suggest that we can seize Muling Pass to prevent them from entering."
"Then let Liu Shixun of Haizhou go around its back, cut off its food routes, capture Yizhou, and cut off its retreat."
"Then they will be attacked from the front and back, trapped in the mountains, delayed for a long time, their energy will be dampened, and they will be destroyed in one battle!"
Zhu Yihai looked at the map. Bolo's reaction was still very quick. His unexpected attack on Denglai was already very sudden, but Bolo still came very quickly.
It is still the most dangerous Muling Pass Passage that I have taken recently.
It was obvious that Bolo was afraid that he would be late and allow the Ming army to seize Qingzhou and Jinan, the two important towns. He went to the meeting alone and came directly to protect Qingzhou.
"Where are the ministries now?"
Zhu Yihai asked Chen Qianfu directly but did not immediately adopt his suggestion because Muling Pass was not in the hands of the Ming army.
Mulinguan Pass is located on the mountain in the south of Linqu County, south of Yidu County, Qingzhou Prefecture.
Zhu Yihai landed in Shandong and after attacking Denglai, his troops were divided into many groups, but they first captured Tiemenguan and Qingdao, then Haizhou, and then raided the hinterlands of Denglai and Denglai.
Only after these small goals are accomplished and troubles have been eliminated can we move out of Qingzhou and Jinan.
"Jin Gongyu led an army to attack Changle and Shouguang in Qingzhou Prefecture. Lu Xiangguan led an army to attack the front and rear of Langyatai Xiahe Village. They were dividing their troops to capture Rizhao and Zhucheng.
The troops who captured Tiemenguan are moving up the Daqing River and have just recaptured Putai and Binzhou."
The progress of the Ming army was still very rapid. After basically clearing the two prefectures of Denglai, they began to attack Qingzhou and Jinan, and they did not encounter much resistance.
Basically, when the Ming army arrived and persuaded the local officials, they and the gentry surrendered.
For those who are stubborn, just firing a few shots will be enough.
Grain
The main reason is that after the two main forces of Kong Youde and Geng Zhongming were destroyed, there were no troops here.
The previous uprisings in Wei County and other places could not be suppressed by Ding Wensheng, the governor of Shandong, and had to rely on General Kong Geng to send troops. In addition, rebellions broke out one after another in Changping, and there were so many thieves in Shandong that they were even more distressed.
The governor's standard camp has not yet been restored and rebuilt. Although the government allows local gentry to organize team training, everyone only keeps one-third of an acre of their own land and does not care about the rest.
Kong Youde died, Geng Zhongming was defeated, and Jinan was completely panicked.
Now there are only some soldiers in Qingzhou Prefecture and Jinan Fucheng, and in other places only local regiments are left to train rural bravery.
"How many soldiers are there in Qingzhou?"
"Not many. There are probably a few thousand people put together haphazardly. They are stationed in Yidu, Linzi, and Linqu, with two or three thousand each. But I think that as long as we mobilize our troops immediately and attack, we should be able to defeat them in one battle.
By then we will be able to block Bolo's reinforcements outside Muling Pass."
In terms of strategic location, Qingzhou is actually the most secure place in Shandong. It is located between Haidai and "Haidai City".
According to the Military Bei Zhi, Shandong combines its strengths to offset its weaknesses, and the area is thousands of miles away. Those who talk about the situation must take Jinan as the gateway and Qingzhou as the foundation.
According to the records of Xingsheng, its land is nestled against mountains and overlooking streams, its foundations are majestic, its battlements are densely lined, and its valleys are stocked with troops. It can accommodate hundreds of thousands of troops. It is the so-called land of abundance, and it was fought over by the ancient kings and uncles.
In terms of the terrain of the region, Daben Nanpan flutters its wings and approaches Xu Yan, and the fork passes through to the left, touching the palm and controlling Denglai.
The twelve levels of Muling are protected by the three thousand waves of the Bohai Sea.
Burma's hegemony is due to its strong local people and the rocky territory of the four fortresses, which is actually due to the dangerous terrain.
Geography here is very important.
Especially if Zhu Yihai wants to occupy Denglai and fight for Qilu, Qingzhou will be the strategic high ground that must be fought for.
However, Zhu Yihai hesitated a little while looking at the map.
Because Jinan is not under his control now, even if he goes to Qingzhou and robs it, and can block Muling Pass first, but because Jinan in the north is not in hand, it is useless to grab a small door and window.
.
Moreover, Qingzhou was a dangerous place, and it would be difficult for Zhu Yihai to transport artillery across. Without artillery, it would be difficult to fight with only troops defending it, even if 10,000 people from Boluo had to fight for their lives.
He was even more worried that when the time came, Boluo would drag him to Muling Pass, and when the Qing army came from Jinan, the Ming army would be trapped in the inland mountainous area to fight the Qing army.
This is a situation Zhu Yihai does not want to face.
The morale of the imperial camp is very high now, and there is no fear of the Tatars. But if the two sides really have to fight hand-to-hand, the gap is still quite obvious.
Just the armor rate is a lot worse. Now the armor rate of the imperial camp does not exceed 30%, while for the elite Eight Banners of the Tatars, the armor rate is almost one per person.
There are definitely still gaps in practical experience and other aspects, and this needs to be faced squarely.
Away from the seaside and without naval cover, there is no chance of winning this battle.
Sun Tzu's Art of War repeatedly emphasizes momentum, which requires the establishment of absolute advantage. You cannot try to block your luck every time and go all out. You must plan well before the war and accumulate enough advantages before starting the war.
As it is now, seizing Qingzhou, grabbing Muling Pass, and blocking Bolo is worth a try from a small point of view. But if we have to consider the overall situation of Shandong, it is a bit dangerous.
He looked back at his map and the construction progress of Laizhou Bastion.
There is a Mi River in Qingzhou that flows into Laizhou Bay, about 200 miles long. However, this river is sometimes wide and sometimes narrow. Especially in summer, flash floods occur and the water flow is rapid. The upper reaches often break the banks, causing the river to change its course. The lower reaches
The alkali beach becomes a fertile field for one season due to siltation and alkali pressure.
The situation in Mihe is not conducive for the navy to contact Qingzhou.
"Since Bolo is here, and he's here in such a hurry, there must be reinforcements from behind, Xu Yan will have troops coming, and there will definitely be reinforcements from the north."
Zhu Yihai stared at the map for a while.
"In this way, Jin Gongyu is urgently ordered to gather troops and horses to attack Qingzhou, Lu Xiangguan takes Yishui City from Zhucheng, and Liu Shixun takes Yizhou City from Haizhou..."
The Lubei Plain is very flat, and Zhu Yihai plans to grab a wave first.
If you can grab Qingzhou, you will be Qing. If you grab it, you can block Bolo for a while.
We don't plan to fight the Qing army in a decisive battle in Qingzhou, but to buy some time first, wait for the main force of the Qing army to arrive, and then withdraw to Denglai, relying on the sea, castles, and naval forces to fight the Qing army.
"Send more scouts out for reconnaissance. You must have a firm grasp of the Tatars' movements, but don't be bitten by their light cavalry. It will be difficult to escape."
The Tartar cavalry can travel hundreds of miles a day on the plains, so they must be careful.
For this reason, Zhu Yihai was more cautious and drew a line. The Ming army should not go out of the Qingzhou Prefecture, and the troops in Jinan Prefecture should not go deeper, and let them almost retreat to Tiemenguan.
Qingzhou City is only about 200 miles away from Daqing River.
The Qing army crossed the Daqing River and rushed to Qingzhou Prefecture for at most one day. Therefore, once the Qing army was found to be close to the Daqing River, the Ming army had to withdraw to Laizhou from Qingzhou Prefecture, Mulingguan, etc.
"Let the ministries come as close as possible."
The Tatars have the ability to run thousands of miles and pursue repeated pursuits, so they must not be underestimated.
"The Tatar reinforcements haven't even arrived yet, but if Boluo comes with 10,000 people, we can withdraw directly. Isn't it too early?"
"It's not early, you have to be cautious when fighting. You must not take it lightly. When the Tatars come, it will be too late." Zhu Yihai didn't think there was anything wrong with this. "If we can attract the main force of the Tatars, we will follow them.
Fighting at the seaside will give them a taste of their power, and we can even send troops to Lushun and Tianjin. We must always keep the initiative in our hands."
