The Tartars' plot succeeded.

Falling behind the retreat, the soldiers of the Northern Expeditionary Army behind the palace and the dozen or so ferries left for them did not have time to sail to safety, and were thus overwhelmed by the swarm of iron horsemen and rangers.

The soldiers of the Northern Expeditionary Army, who had just arrived in the center of the river, witnessed all this tragic scene, their eyes were about to split, and everyone's eyes were red!

This kind of hatred, I'm afraid that I hate it to the bones.

It's a tragedy.

Lu Zhiyu was right.

After Wu Zheng led his troops to retreat to the east bank, the Tartar cavalry, who had tasted the wonderful taste of victory, quickly waved their troops south.

The next day, Suqian was lost, and the 800 defenders fought to the last soldier, and they were all gone!

……。

The defeat was like a mountain.

This is true on either side.

Either hold on, or a river of spring water flows eastward.

The only exception to this is when an external force intervenes at the right time.

Wu Zhengsuo, who was trapped east of the Zhihe River, had actually fallen into considerable passivity, and there was no possibility of moving at all, of course, it was not a desperate situation, because as long as he crossed Luoma Lake, he could meet with the defenders of Shuyang, and defend Shuyang, which was not the same as the danger of Huai'an City before.

However, Wu Zheng's troops at this time were less than 5,000 people, the lack of ammunition, and the speed of the march was not as fast as the enemy's cavalry, which limited the possibility of Wu Zheng to reinforce to the south, and he could only "sit back" and watch the loss of Suqian and be anxious.

However, in many cases, the victory or defeat of a war does not entirely depend on the overall planning of the commander, and the subjective initiative of the generals sent from all walks of life occupies a very large variable and effect.

The Qing army didn't know, and Wu Zheng didn't know either, that a powerful "external force" appeared at the right time.

Song An tried his best to encourage Qian Qiaogong, who was "frustrated" to stay in Qinghe, and crossed Hongze Lake to blitz Sizhou in the west, which is of deep meaning, this is not just to relieve Qian Qiaogong's depression and rob Sizhou war horses, Song An has an indescribable plan.

It is said that how bold man is, how productive the earth is.

Dogs that can bite people don't bark, although this is not to be heard, but Song An belongs to such a heart.

As the range of enemy cavalry activities south of Huai'an continued to compress, the Changlin guards lurking in various places began to move, and more and more information began to gather.

Dolgon in Xuzhou!

This dispensable, seemingly true and false information made Song An think.

This is a fleeting thought, or an idea that is not feasible, some people will laugh it off, but some people will take it seriously and give everything for it. Song An belongs to the latter.

He's going to play a big game of chess!

Huai'an Province borders Xuzhou Province, and the border between Suqian and Xuzhou Province is only three or four hundred miles, which is entirely possible for launching a surprise attack, but the key to success or failure is not the number of troops, but the suddenness and the accuracy of Dolgon's information in Xuzhou.

It stands to reason that this information must be reported to Wu Zheng by Song An, but Song An controls Chang Lin Wei and has great authority in his hands, and this kind of information that has not yet been verified can be reported or not.

At the same time, Song An knew Wu Zheng's personality too well, and in Wu Zheng's opinion, a Dolgon, especially a Dolgon who had not had much time left, was not worth consuming the lives of hundreds or even thousands of soldiers in exchange.

In other words, Wu Zheng would turn a blind eye to Dolgon's presence in Xuzhou.

This is not Song An's random speculation, because the previous news of Dolgon's presence in Pei County was confirmed and reported to Wu Zheng, but Wu Zheng did not mention the idea of "beheading" Dolgon until he sent troops to Haizhou and Suqian.

But Song An is different, as an intelligence officer at this time, Chang Linwei has almost no outstanding performance in this war, which has caused his young master to be trapped in Huai'an City for more than half a month, and he is extremely self-blaming and depressed.

Song An wants to redeem himself, to be precise, he wants to prove his worth and prove to his young master that he wants to play a big game of chess!

At this time, a piece of information from Fengyang stimulated and strengthened Song An's thoughts, that is, the original Xuzhou army under Azig was stranded in Huaiyuan and did not return to Xuzhou north for a long time.

This made Song An even more convinced of the emptiness of Xuzhou's troops.

But Song An's troops were insufficient, Huai'an and Yangzhou could use Changlin to guard a total of six or seven hundred people, and they were not suitable for battlefield fighting, and Wu Zheng left Song An with only 3,000 defenders of Huai'an City, and they were not allowed to leave Huai'an City without permission.

Even if Song An was bold and reckless, and all the available forces in his hands were combined, it would be impossible to make a surprise attack on Xuzhou with a chance of victory.

At the same time, Wu Zheng was leading his troops to attack Pizhou at this time, and Song An wanted to raid Xuzhou, but he couldn't bypass Wu Zheng.

This is often the case, and although spears and shields are opposites, many times they can coexist and, with clever deployment, become complementary.

After Song An learned that the enemy army had set up three lines of defense in Pizhou and Luliang Mountain in order to resist the approach of the Northern Expeditionary Army to Xuzhou, he had a flash of inspiration and thought of a feasible plan.

Xuzhou's troops were originally empty, and if the force of three lines of defense was set outside, the troops would be even more stretched.

It happened that Qian Qiaogong was "feeling sorry for himself", so Song An gave him a "bad idea" and went to Sizhou to grab a war horse.

There are war horses in Sizhou and there are not many defenders, this information is true, but Song Anning is willing to take responsibility for Qian Qiaogong, and the real intention of encouraging Qian Qiaogong to attack Sizhou in the west is not here.

Song An wanted Qian Qiaogong to attract the army of Huaiyuan Azig and buy three days for himself to blitz Xuzhou.

In Song Zi's planning, not only Qian Qiaogong was a pawn to attract the enemy, but even Wu Zheng was also a pawn to attract the enemy, because it was precisely because Wu Zheng's troops were attacking Pizhou that the main force of the enemy army in Xuzhou could be attracted to the three lines of defense.

In fact, Song An was not wrong, in the city of Xuzhou, there were only 300 guards around Dolgon, of which 60 were cavalry, and it could almost be said that the huge Xuzhou City was an undefended city at this time.

Of course, once something happens, it will only take less than a day to rush back to Xuzhou from the last line of defense, which is where Dolgon's confidence lies.

In Dolgon's opinion, no one could annihilate his three hundred guards in half a day, unless it was a large army, but this was impossible, without a large army, it could break into Xuzhou City without knowing it.

Unbeknownst to Dorgon, however, Song An had his own means of marching differently from the regular army.

At the same time, after the Northern Expeditionary Army conquered the Qing River to the north, the Qing army's blockade of the canal and waterway was far less than before, and even because of the rout of Chen Jin, it almost lost control of the waterway.

However, the canal is the main artery of north-south commerce, and even at the time of the national war, the merchant fleets passing between the north and the south are still endless.

It is indeed not easy to transport a large army from the waterway to the north, even if the enemy is no longer able to blockade it, but the eye can always see, once it is known that the enemy is coming from the canal, it is necessary to directly lay an ambush on the dock, and ensure that one dozen and one are accurate.

Therefore, the number of raiders cannot be large, nor can they be small, and less will not play its due role.
