Most of the Jiannu's army were cavalry and were highly mobile, but this did not mean that their grain, grass and baggage were also highly mobile.

The so-called soldiers and horses have not moved, grain and grass go first, even if Jiannu is mainly looting this time, and there is not much grain and grass with them, and the 70,000 army must have at least 50,000 or 60,000 people to transport grain and grass.

So this time, Jiannu entered the customs, saying that it was 300,000, but in fact, it was not too false, but except for the elite soldiers, most of the rest were people's husbands, not soldiers.

Now after the division of troops, Abatai has 70,000 troops left, in fact, in addition to these 70,000, there are 50,000 or 60,000 people, these people, who do not even have weapons and have almost no combat ability.

Therefore, Lao Zhu asked Bai Guangen to lead the cavalry to harass, targeting these people who transported baggage, grain and grass.

More than 100,000 people are not a few, as long as the army is slightly out of touch when crossing the Great Wall, Bai Guangen can lead the cavalry to pounce on them and bite them fiercely.

And this time, there is not much grain and grass brought by Jiannu, if Bai Guangen is allowed to let go of harassment like this, Abatai's army is estimated to not be able to go to Jizhou, and the grain and grass will have to be consumed about the same.

At that time, unless Abatai had absolute certainty of defeating Jizhou in a short period of time, he would definitely not dare to let Bai Guangen harass him like this.

But marching between the mountains and mountains, it is difficult to concentrate the army, as long as Bai Guangen divides his cavalry into several groups, Abatai will definitely not be able to guard against harassment.

Therefore, as long as Bai Guangen is released, Lao Zhu is absolutely sure that he can force Abatai back to Huangya Pass.

Although Bai Guangen is arrogant on weekdays, in the face of Lao Zhu, he does not dare to have the slightest intention of disobedience.

After receiving the order, he directly led the army to advance, and when he arrived at the destination, he let the Shenji battalion and archers garrison the Great Wall, while he took the initiative with the cavalry.

As a veteran oilman, Bai Guangen knows very well how to fight the harassment war.

He was not close to Abatai's army at all, and cruising around Abatai's army with his cavalry, and after encountering Abatai's scouting horse, he did not hesitate to eat it.

Then he sent his cavalry as spies, and if Abatai showed the slightest sign of pursuit, as long as there were a few more people coming, he immediately took the cavalry away, and there was no sign of fighting Abatai.

But if Abatai's army was slightly decoupled from the logistics of transporting the baggage, he would pounce on it with his soldiers, kill the people, and then directly burn the grain and grass of Jiannu on the spot.

In the past few days, although Bai Guangen has gained little, he has harassed Abatai a lot.

"Amma, I'll lead the troops to destroy them!"

Bolo is extremely irritable now, Bai Guangen with the cavalry is like a hungry wolf hovering around them, as long as they show a little flaw, they will come up and bite them, which makes Bolo's nerves always tense, and he is always guarding against Bai Guangen leading the army to kill.

But there is only a thousand days to be a thief, how can there be a reason to prevent thieves for a thousand days, in order to guard against Bai Guangen, Bolo has not slept well for several days, and now he wants to catch Bai Guangen, and then drag him to death behind the horse.

"Their scouts are always watching us, and as soon as you get out, they will get the news, turn around and run away, and you won't be able to catch up with them."

"This cavalry is too vigilant, their purpose is not to let us lose much, but to force us back to the Yellow Cliff Pass, even if it is useless to set a trap."

Abatai also felt a little headache now, in order to catch Bai Guangen, he set several traps, but Bai Guangen was not fooled once.

Bai Guangen is like an extremely patient old hunter, he is not completely sure and will never make a move, which makes Abatai have no good way to take Bai Guangen.

"Then I'll take a team of people to stare them to death!"

Bolo's eyes were a little fierce and said: "Amma, you give me 4,000 people, even if you can't chase them, I can make them unable to get close to the army even half a step!" ”

Their Manchus and Mongols are originally a people on the steppe, and in terms of cavalry, whether they are Manchus or Mongols, they can definitely crush the Ming Dynasty.

As long as those cavalry of the Ming Dynasty dared to give him the opportunity to engage head-on, even if it was four thousand against four thousand, he would be sure enough to defeat them head-on.

"Don't be rash!"

When Abatai heard Bolo say this, he directly reprimanded him, "The most important thing in leading troops to fight is patience." ”

"You go in pursuit, have you ever wondered what to do if they lure you into an ambush?"

When the two armies are engaged, the pursuing side is the easiest to ambush, especially on such a battlefield that the enemy has already chosen.

Bolo has a violent and irritable personality, if he is asked to pursue Bai Guangen, Abatai doesn't have to think about it at all, Bai Guangen will definitely anger Bolo, and then set up an ambush to leave him behind.

For this son, Abatai is still very important, so he will definitely not let Bolo lead his troops to pursue Bai Guangen.

"But it can't go on like this!"

Bolo was extremely irritable in his heart, and he said directly: "This cavalry has seriously affected the marching speed of our army, and it has not yet reached the Great Wall, and when we cross the Great Wall, the terrain will be even more dangerous, and the army will inevitably be scattered by the terrain." ”

"At that time, if they come to harass again, we won't be able to protect the baggage at all."

"And even if we can protect it, with the current marching speed, I'm afraid we won't be able to reach Jizhou, and the grain and grass will be exhausted."

"It's okay, I didn't want the army to pass through there in the first place."

Abatai shook his head steadily, and then said: "As long as you put a certain amount of pressure on the Ming Emperor, let him sit still and send troops out of the Yellow Cliff Pass." ”

In Abatai's plan, he only needed to send 10,000 cavalry, plunder along the way, and go straight to the important town of Daming.

After the Ming Emperor received the news that the 10,000 cavalry had entered the pass and plundered, he would definitely send troops to support.

At that time, the rest of his army will be able to eat all the reinforcements from Huangya Pass.

To put it bluntly, Abatai is fishing, as for how many Ming troops can be caught, it depends on how many people the Ming Emperor will send to support.

After pacifying Bolo, Abatai withstood Bai Guangen's harassment and marched directly to the edge of the Great Wall.

At this time, the Shenji Battalion and the archers, who had been waiting for a long time, directly launched an attack on the Jiannu army.

They didn't mean to fight hard with Jiannu, and when the Abatai army approached, they moved along the Great Wall, and when the firearms of the Abatai army were transported, they didn't even stop, and withdrew directly along the Great Wall.

Such a short-lasting resistance battle on the Great Wall of the harassment belt brought more than 3,000 casualties to Jiannu in total, which was harmless to Abatai.
