But if it is transported to Xuzhou by hundreds of people who have been carefully dressed up by Qiao Zhuang, it will be too easy. Even if they are monitored by the Qing army in Yanhe, no one doubts, because almost no one thinks what role a team of hundreds can play in Xuzhou City. If you really want to do this, there will be only one person who will die!

This gave Song An an excellent opportunity to use Qian Qiaogong's troops to restrain Huaiyuan Ajige and Wu Zheng to restrain the main force in Xuzhou. He could lead hundreds of people to disguise themselves as an ordinary caravan and go straight to Xuzhou through the canal.

This is what was mentioned earlier as "external force".

But the problem is that Song An's big game was forced to stop at halfway through.

It is said that plans will never keep up with changes.

Such a "perfect" idea, suddenly having sex in the womb, really made Song An depressed.

But for Song An, Wu Zheng was all about him, just as he often said, "I am a member of the Wu family in my life, and a ghost of the Wu family in my life." After leaving the young master, he was nothing.

Just when Song An led 18 merchant ships, loaded with 600 disguised soldiers, set off from the Qinghe River and headed north along the canal to the vicinity of Taoyuan.

The Qing army in Pizhou used innocent people as a wall of human rights and forced the prince to retreat eastward. He suffered heavy losses on the banks of Zhihe River. At the same time, the enemy took back Suqian and continued to move south, which forced Song An to temporarily change and terminated his "beheading" plan.

Song An immediately ordered all his troops to land and set up an ambush to block the enemy troops going south in Yazhen in the southeast of Suqian.

....

Anyone with a little common sense knows that in the era of cold weapons, the king of the battlefield was the cavalry.

The king among the kings is heavy cavalry and light cavalry, which is the most perfect combination.

With the ability of heavy cavalry to attack and the maneuverability of light cavalry, he is almost invincible and can defeat everything.

This is just like the heavy tanks in later generations that had to be added with light tanks and armored vehicles.

Of course, it can also be combined with infantry coordination, but in this way, the advantage of speed will be greatly reduced.

Therefore, only the combination of heavy cavalry and light cavalry is perfect. Of course, this refers to field battles and raid battles.

Although the Qinghe River in Suqian is a city, the walls of such small cities are less than two people high, and they cannot form any strong resistance to the cavalry.

This is the main reason why the enemy cavalry dared to take advantage of the situation and head south.

Stimulated by two consecutive victories, they abandoned the infantry and combined heavy cavalry and light cavalry, and quickly moved south from Suqian, targeting Qinghe, intending to fight, and eradicating Chen Jin's poor command, causing the Northern Expedition Army to cross the Yellow River.

They are very arrogant, of course, it should be said that this is true.

More than 800 heavy cavalry, under the cover of two thousand light cavalry, is theoretically enough to sweep across the banks of the Yellow River. It can be said that they encounter gods and kill gods, and the Buddha blocks and kills Buddhas.

Just like the chief general of this mixed cavalry, Jiala Ezhen (equivalent to the level of the Ming army's garrison to the general, and equivalent to the level of the brigade in later generations), Hu Nigaluohe, said before setting off, "The Southern Barbarians have no ability except to be clever and have little skills... As long as we drive them down the Yellow River in one go, we can advise the court. What is the most reliable new musket army?!"

But everything is absolutely absolutely true. If war is really a competition of objective factors, Wu Zheng would not be forced to retreat to the east bank of Zhihe River.

In fact, the three defense tactics on the banks of the Strait River were correct before, and under specific conditions, the cavalry was definitely not an invincible myth.

Therefore, when this cavalry with more than 2,000 people marched on the official road, the arrogant expression and momentum were like a soldier's finger, invincible.

But when they arrived at the turn near Yazhen, the scene that they had no time to regret happened suddenly.

Yazhen is located at the corner of the official road about fifty miles east of the ancient city.

Because the canal has a sharp turn here, the construction of the official road has also formed a sharp turn.

The Qing cavalry had to lower their speed, otherwise they would rush out of the official road and fall down the cliff on the right. The cliff was very high, about two meters away. This height would generally not kill people. But if the speed of the war horses being galloped, even if they had a golden bell cover to protect the body, they would have to be crushed into flesh.

Just a turn of the official road made this Qing cavalry, who had just been arrogant, taste what it means to die without committing suicide, and taste what it means to cover artillery fire in advance.

Here we have to explain why only a few hundred people in Song'an can cover the road with artillery fire.

At this time, the First Army had recovered Taizhou, and Chi Erhan and Zu Dabi succeeded in the sudden attack on Xinghua. The north-south transportation line was immediately opened, and the first batch of supply materials had been transported to Qinghe. It was Song An who arrived in Qinghe that gave Qian Qiaogong a "bad idea".

It is naturally impossible for this first batch of supplies to have heavy artillery. Even if there are heavy artillery, Song An would not have taken heavy artillery to raid Xuzhou.

Isn’t this a joke? The six-pound field cannon weighs eight or nine hundred kilograms. How can it maneuver?

Besides, even if transported to Xuzhou, it will not have any effect on siege. Xuzhou's city defense is not comparable to that of a small city like Suqian and Qinghe. Six pounds of cannons hit the city wall, which is just a pit.

Such a big attack would be like seeking death. Son An would naturally not be so stupid.

Among the first batch of supplies, the largest proportion were paper bullets (not typos, but real paper bullets. At this time, the front loading was wrapped in oil paper, thicker than the middle finger, about the same length, and there were fire medicine and a metal projectile) and tiger squat mortar shells.

The tiger squat mortar can be disassembled into two large pieces, the barrel and the base. The barrel is heavier, about sixteen kilograms and twelve kilograms of base. This weight is easy for soldiers to carry in marching. Therefore, when equipping the Northern Expedition Army, it is most popular among soldiers.

However, the power of this cannon is small (because of shell technology and black gunpowder), so it is suitable for ordinary infantry and light armored infantry. It is basically not fatal unless the shell falls under the horse's belly and explodes.

The two guards in Huai'an City fought hard for nearly a month, and even carried 160 paper bullets (two big bags on the left and right waists) were exhausted. The tiger squat cannons had already been exhausted. Therefore, before crossing the river to attack Qinghe, these tiger squat cannons without shells were left in Huai'an City.

Song An was going to raid Xuzhou, and he was able to use it. He didn't bring many, one hundred and twenty doors.

This is used to make local breakthroughs and breakthroughs after entering Xuzhou City. At this time, Song An used it on the turning corners of the official road, forming a dense artillery coverage.

Even if you are a rusty and ragged kitchen knife, as long as you can kill people, it is a good knife.

Although the tiger squat cannon is not very powerful, it is too much.

A needle is difficult to kill a person, but if the needle is dense enough, it can still kill a person.
