Since it is known that three or four counties have been lost, and even if it is delayed for a while in a short period of time, the lost territory will not exceed five counties, and there is a great probability that the Jiangyin line will defend and prevent the spread of the Tartar situation.

Then, Zhu Shuren didn't have much urgency, so he had to take the enemy lightly and immediately turn to an all-out general attack on Duoduo.

After all, Duoduo still has more than 80,000 soldiers to fight, although he is tired, but when Zhu Shuren arrives at the battlefields of Danyang and Jurong, the Qing army will have at least two or three days of rest, and their physical strength will be greatly restored, and there will be not much weakness to take advantage of at that time.

In contrast, if the damage was controlled within the range of five counties, and the supplies of Duoduo were slowly consumed, and when he was exhausted in one fell swoop, it would be much easier and more stable in the end.

Considering that Duoduo had already entered the rich land of Jiangnan, Zhu Shuren estimated that it was impossible to consume the other party's food.

If there is really no food, it is estimated that the people of Chang and Zhen counties will be slaughtered and plundered first, and the loss will be too great, and the damage to the sustained productivity in the Jiangnan region will also be too great.

Therefore, in terms of food supply, at most, as the winter deepens, the feed of the horses will become worse and worse, which will relatively weaken the sustained combat endurance of the Qing cavalry. In addition, the quality of food in the Qing army also has a high probability of declining-

Now Duoduo has only crossed the river for four days, and by relying on robbery, he can even maintain the life of the troops with wine and meat. The reason why he was able to fight so hard in the previous attack on Nanjing was also related to Duoduo's willingness to spend money and make generous shots. Which of the soldiers who participated in the siege of the city first drank wine and meat for two days to boost morale.

And the extravagant life of wine and meat, Duoduo will last for ten days and half a month at most, after eating up the wine and meat accumulated by the rich families in the five counties of Changzhen, there is no outside supplies to transport in, and it is blocked, although Duoduo's army will not be hungry, but it will definitely soon enter a state of vegetarianism.

If we stay close to a month, there may be a shortage of fresh vegetables and refined grains, and we will have to eat bran pickles or at least coarse grain cakes.

In addition to the decline in the quality of grain and grass, Zhu Shuren looked forward more to cutting off the enemy's supply, which was to slowly weaken Duoduo's weapons and ammunition.

In terms of weapons, the Qing army's armor rate will be rapidly weakened as they continue to attack the city. In the two days under the city of Nanjing, the soldiers of the Eight Banners died less than 3,000 directly, and the rest were Han and Mongolian troops. But the fine iron cotton armor left over from the bodies of the dead of the Eight Banners alone has already exceeded five thousand pairs.

When the Qing army attacked the fortified positions, they often let the elite dead soldiers set several sets of heavy armor, but they did not prepare so much armor in normal times, and they could not use it in field battles. Therefore, they were all temporarily allocated before the siege, so that the lightly armed troops who did not need to ascend first would even out the iron armor and temporarily lend it to the dead soldiers.

The loss of these dead soldiers under the city means that at least twice their number of iron armor has been lost, and a considerable number of the soldiers who survived will also be converted to light armor, or have to peel off the high-quality armor of the Han and Mongolian soldiers.

The loss of knives, guns and weapons in these aspects is nothing, and the Qing army is not bad at this point. Another shortcoming in armament supply is the loss of firearms, ammunition and arrows.

On the first day, the Ming army was injured and damaged four or five guns, and on the second day, there were even more battle damages, and several of them were blown up and other damage because of the continuous high-intensity firing.

Duoduo's Hongyi cannon combat power has dropped from 46 at the beginning of the river crossing to barely 30 left, even if a few can be salvaged after subsequent repairs, the total number will not exceed 35.

Before the Qing Kingdom entered the customs, Chongzhen began to try to cast cannons in six years, and Chongzhen began to mass-produce in eight years, and after that, it took ten years to save more than 200 Hongyi cannons, and its annual output also slowly climbed from the initial dozen guns per year to thirty doors per Chinese New Year's Eve.

After entering the customs, relying on the inventory of the Ming army and the Chuang army, which seized half of the northern part of the country, the total stock of Hongyi artillery of the Qing army once exceeded the peak value of 300 guns. After the integration of the military production capacity of northern China, the total number of artillery casts in the Qing controlled areas can also be further increased from 30 guns outside the customs to about 50 guns.

Therefore, Duoduo lost fifteen or sixteen Hongyi cannons in a few days, and this battle loss is definitely not a small number, it is equivalent to one-third of the total production capacity of the Qing Kingdom next year. As long as Zhu Shuren destroys more than 50 heavy artillery pieces of the Qing army every year in the future, he will be able to reduce the artillery strength of the Qing State more and more.

The loss of artillery is only a microcosm, and behind it is the rapid depletion of consumables for the Qing army.

According to the limited information gathered by Shi Kefa from the captives, Zhu Shuren estimated that if there were one or two more battles of Nanjing, all the Qing artillery would be dumbfounded due to lack of ammunition.

Muskets, ammunition, bows, crossbows, and arrows will also be depleted after three or five battles of this intensity. Of course, if the Qing army was willing to use the cannon to shoot stone balls, they could squeeze some gunpowder from the musket unit for the cannon, but anyway, the meat was rotten in the pot, and the cannon consumed a lot of medicine, so the musket had to be scrapped in advance.

Of course, the prerequisite for achieving all this, Zhu Shuren has always been very sober: he has to ensure the thoroughness of the blockade, and completely cut off even the last trace of contact between Duoduo and the Qing army in Jiangbei.

For a period of time in the future, even if there is no field battle, it does not mean that the Ming army has done nothing. The patrol of water warfare on the river must always maintain high intensity, and the division of troops on land cannot be slackened to encircle and chase and intercept the mouth, and finally catch the flaw in the movement war of the Qing army, and hit it with one blow!

……

After deploying this strategy and resolutely implementing it, in the next three or four days, the smoke of land warfare on the battlefield of Changzhen really dissipated some temporarily.

Duoduo was mentally prepared at the beginning, "Wait for Zhu Shuren to pursue rashly, and then he will turn around and kill back, and take advantage of the fact that the morale of the Qing army has not fallen to the extreme, and hurry up to fight a decisive field battle to encircle the point and send reinforcements."

Therefore, after he retreated to Jurong County, he also showed weakness, so that the rear army put on an embarrassed posture, and on the way back to Jurong from Nanjing, he even left some looted heavy property and battle-damaged old armor.

This makes it clear that I have seen too much of the Romance of the Three Kingdoms, and I want to learn from Cao Cao's literary ugliness of throwing away his belongings to lure Yuan Shaojun into chaotic formation, snatching property, and advancing lightly.

With Zhu Shuren's IQ, how could he be greedy for this little profit? So Duoduo's acting skills in this round were in vain.

In contrast, on the way back to Jurong and Danyang, Duoduo was very concerned about getting supplies from Jiangbei again.

After he crossed the river with the main force some time ago, the rear army fleet was intercepted and killed by the Zheng family's uncles and nephews, and the ships and sailors suffered considerable losses, which also caused the rear army not to dare to cross the river to reinforce again. But at that time, there were still a small number of warships and small boats that were hidden by Duoduo in time to stop the loss and pull back to the dock of Longtanwei.

Relying on this small boat, after the failure of the storming of Nanjing, it is absolutely impossible to transport the army back to Jiangbei, even if there are loopholes in the Ming army patrolling the river at night, but how many people can this boat transport? Duoduo can't abandon his army and flee, can he?

In addition, Duoduo didn't feel that he couldn't do it until this moment, he didn't want to run away at all, he was just afraid that a protracted war would lead to a shortage of cannonballs and gunpowder, so he wanted to use these ships to secretly return to Jiangbei to transport some of the most scarce armaments.

Food, arrows, clothing, etc., these are too much space, there is no need to transport them from the north of the river, and the remaining precious transportation capacity cannot be wasted on these heavy things.

On the night of November 18, two days after the end of Duoduo's Battle of Nanjing, Duoduo, who had returned to Danyang, ordered to concentrate the only fleet he had, secretly detour, bypass the Jinshan Temple on the river, set off from the wharf of Gaozi Town, and go to Yizheng County, the capital of Yangzhou, in the north of the Yangtze River.

In order to get in touch with the generals of the Qing army who were stranded in Yangzhou, and transfer gunpowder. The Qing army also stocked a large amount of gunpowder in Yangzhou, including the slowly concentrated transportation from the rear during this time.

However, although the scale of this smuggling was many times smaller than that of the troop transport a few days ago, and it seemed to be many times more hidden, it still fell for the trick of the Ming army patrolling the river.

Zheng Hongkui's sailors were stationed in Jinshan Temple, the scout boats were very dense, and the Ming army was also bloody, Zhu Shuren a few days ago, after learning that Duoduo had crossed the river, he immediately asked his subordinates to allocate another batch of binoculars to Zheng Chenggong, so that Zheng Chenggong could not use it up and give it to his uncle.

Zhu Shuren is not worried about the spread of high-powered telescopes with higher accuracy than this era, and even the grassroots officers of the Ming army's scout fleet can be distributed, even if there is a risk of being captured by the enemy in the war, he doesn't care.

Anyway, the telescope in the land battle is not too anti-heaven equipment, the main thing is that the navy is of great use, and the navy of the Ming army is an absolute advantage. As long as you can completely kill Duoduo this time, this risk is worth taking.

What's more, if in the water battle with Duoduo, occasionally the officers of the Ming army scout ships were captured and captured, as long as Duoduo was destroyed in the end, wouldn't these captured things from the past return to Zhu Shuren's pocket?

In the words of a 21st century saying, it is "I kill you these things, and I don't need you to give them".

Unless new equipment is captured in contact with the Qing army in Jiangbei, it is possible to completely lose it and be analyzed and guarded by the enemy.

In addition, in order to better intercept and kill the Qing army's smuggling boats, Zhu Shuren also took out a new equipment in the firing line during this time, which was used with a telescope - he equipped the Ming army scout ships with some shiny metal reflectors, that is, some bright metal on the surface was beaten into a concave surface, and covered behind the torch, which could focus the light and achieve the original similar searchlight effect.

This kind of thing is actually not worth much technically, as early as BC, the lighthouse in Alexandria, Egypt, used a copper mirror reflector to reflect the flames of the lighthouse. It's just that the ancient reflector has no mathematical blessing, does not calculate the reflective curvature, and the efficiency is relatively low, and the process and accuracy of this era can be improved a little, so that the firelight of the searchlight can be easier and farther.

The Ming army had so many new weapons for patrolling the river, and Duoduo's attempt naturally ended in failure, and most of his last dozens of ships that could cross the river were also discovered by Zheng Hongkui's scout boats from Jinshan Temple, and then released fireworks similar to monkeys on the river for the first time to quickly warn, attracting a large number of warships to intercept and kill.

Duoduo had killed hundreds of elite soldiers who had participated in the smuggling in vain, and he was so angry that he was so angry that he was in smoke. He also ignored the fact that the troops under his command were still purging Wujin County and wanted to attack Jiangyin. On the Zhenjiang side, he couldn't help but open a new pit again, divided tens of thousands of troops to kill Jinshan Temple first, and pulled out Zheng Hongkui's bone in the throat first.
