Jiang Quanyi's idea, from a tactical point of view, is actually not wrong, hit the enemy with a dismount, deter it, and then negotiate, you can open your mouth and get what you want.

But Jiang Quanyi didn't understand after all, this approach was built on the basis that the strength could definitely crush the other party, otherwise, when you want to stop, the enemy refuses to stop, what should I do?

The strength is slightly higher than the opponent, or theoretically can defeat the opponent, does not mean that the opponent is crushed.

This is like the later generation of "country A" fighting Vietnam, the disparity in strength is enough to be related, but as a result, it was a stalemate war of attrition for more than ten years, and finally had to withdraw its troops in disgrace.

What's more, in terms of current strength, the comprehensive strength of the Qing court is stronger than that of the Yixing Dynasty and the Wu Zheng General's Mansion, which is beyond doubt.

The victory of only partial military strength does not represent comprehensive strength.

For example, in terms of military strength, Wu Zheng gathered a total of 200,000 people, and he also had to garrison more than a dozen prefectures on three sides. But as for the Qing court, not counting the Eight Banners and the Eight Banners of the Han Dynasty, there were 400,000 or 500,000 troops in the surrender of Wu Sangui, Kong Youde, Geng Zhongming, and Shang Kexi Sanshun Wang, and there were no less than one million Qingming troops from all over Jiangbei.

And the fiscal tax is four times that of General Wu Zheng's mansion. Last year, the annual income of the Great General's Mansion was only more than 13 million taels, while the Qing court had nearly 60 million taels last year.

Therefore, Jiang Quanyi's idea is correct from a tactical point of view, but from a strategic point of view, it is wrong.

Because, there is no way for him to truly grasp the initiative on the battlefield.

To put it simply, it was to hurt the enemy, and Jiang Quanyi could not bear the enemy's counterattack.

……。

What made Wu Zheng most angry about Jiang Quanyi was that he didn't actually let the herald report it, and only led the army to set off in the middle of the night.

Instead, he buried the pot in the evening to make rice, so that the soldiers had a good and full meal, and then waved their troops north.

In other words, it was three hours earlier than the time he sent the herald to make a report.

Three hours, according to the speed of ordinary people, one hour will walk about 20 miles, but the marching speed of the Northern Expeditionary Army is strictly regulated by the infantry drill code, an ordinary march is 26 miles in an hour, and a rapid march needs to reach more than 30 miles.

Thirty miles in an hour, almost the speed of a jog.

And it's not just one hour, the drill code stipulates that a long-distance run training is four hours, that is, more than 100 miles.

And Jiang Quanyi himself has a careful mind not to be stopped by Wu Zheng, how can it be that Taizhou Wei marched slowly?

In fact, when Wu Zheng got the report, Jiang Quanyi led his troops to pass the old fort and approached Baoying.

Wu Zheng sent someone to give an order to Jiang Quanyi to "stop the attack", which was a joke.

Because when this order was transmitted to Baoying, Jiang Quanyi had already led his troops to capture Baoying, and was taking advantage of the victory to attack Dahewei.

The Ming Dynasty set up guards, and most of the ordinary houses were several houses and one guard.

Only important military towns and key passes can have one government and one guard.

For example, Taicang set up Zhenhaiwei, Songjiang set up Jinshanwei, Jiaxing set up Hainingwei and so on.

But Huai'an Mansion has three guards, not to mention the one in Pizhou, just say that Huai'an Mansion governs Shanyang, and there are two guards in one city - Huai'an Wei and Dahewei.

This is because Huai'an Mansion is not only the center of water transportation, the center of transportation, and the center of river control, but also the distribution center of the salt industry and the important place of guan.

The difference between Huai'an Mansion and other mansions is that the two guards of Huai'an Mansion are directly under the jurisdiction of the military governor's office in the imperial court, and the general guard command division is different, the grade is relatively higher, and the two guards are not only responsible for defense and tuntian, but also responsible for the task of transporting water.

The two guards of Huai'an Mansion not only have their own independent shipyards, ordnance bureaus, teaching institutes and health school facilities, but also have nearly 400 ships of more than 600 stones, which is enough to transport an army of tens of thousands of people at one time.

In fact, this is also the reason why Wu Zheng was worried that during the Northern Expedition, the offensive would be blocked and he would fall into a stalemate.

The Grand Canal is a double-edged sword, hurting others as well as hurting oneself.

In other words, once the Qing court went all out south, the number of subsequent reinforcements was unimaginable.

……。

Jiang Quanyi led 10,000 Taizhou Wei forwards, two nights and one day, from Xinghua to hundreds of miles with the momentum of ploughing and sweeping caves.

The results of the battle are huge, but the Taizhou guards are also blunt.

At the end of the crossbow, it is difficult to penetrate Lu Mian.

The assault on Dahewei was blocked.

At its peak, there were 8,000 households, as many as 10,000 personnel, more than 5,000 regular troops, more than 2,000 officers and soldiers defending the city, and 10,000 pieces of annual ordnance.

At the end of the Ming Dynasty, the health system collapsed, but because Jiangnan was rich, and Huai'an was different from the northwest, it was a major tax town, so this collapse did not spread.

Therefore, the Qing court almost fully accepted Huai'anwei and Dahewei.

As a result, the second guard has nearly 10,000 regular troops in Huai'an Mansion, and at the same time, the soldiers who can be quickly recruited are also as high as 10,000.

In other words, the number of enemies Jiang Quanyi faced was at least 16,000 or more.

At the same time, since Huai'an Mansion is an important military and tax town, the degree of defense of the city wall must also be high.

Taizhou Wei wanted to break through Huai'an with a quick battle, which was almost impossible.

After three successive waves of attempts to attack the city failed, Jiang Quanyi did not make a desperate bet, he immediately ordered to camp outside the city, repair for one night, and attack again tomorrow.

……。

At this time, Wu Zheng's order to "stop the attack" was passed to Jiang Quanyi.

Jiang Quanyi took the order, looked at it for a while, then raised his head and laughed, then rubbed his hands together and ignited it on the candle, and in an instant, the paper ball turned into ashes.

Dare to deal with the general's military order like this, is this a rebellion?

Just when the herald was shocked, Jiang Quanyi said in a deep voice: "You go back and transfer to the prince, the 10,000 Taizhou guards stationed in Xinghua, Jiang has already moved north, please send another army to garrison it...... If Jiang can't capture this city, he will die in front of the city of Huai'an, and he doesn't have to work for the prince, and he will use military law in the future...... If you are lucky enough to capture this city, please also ask the prince to remember Jiang's meritorious service, be able to redeem the merit, and forgive Jiang for resisting today's order! ”

Jiang Quanyi immediately issued three orders, ordering the follow-up main force of 10,000 to rush over, ordering the 10,000 defenders of Xinghua to go north immediately, and at the same time sending a messenger to Gaoyou in the south, asking Fang Guoan to lead his troops to reinforce Huai'an.

Early the next morning, Jiang Quanyi continued to feint and attack Shanyang City.

First, in order to contain the defenders in the city, and second, to wait for the main force to arrive with artillery and other siege weapons.

At the same time, after deliberation, Jiang Quanyi resolutely divided his troops and sent a partial division to the west to attack Gaoliangjian through the Chahe River, intending to outflank the north of Shanyang City along the north of Hongze Lake.

In fact, at this time, if according to the goal before the Wu War, Baoying and Yancheng fell, and the entire Yangzhou Mansion was in hand, and the strategic goal had been initially achieved.

However, due to Jiang Quanyi's "unauthorized advocacy", he lost a good opportunity to "turn hostility into friendship" with the Qing court.

This made the war gradually expand and become uncontrollable.
