Guo felt that when Yang Guang dealt with Goguryi, if he could be a little more cautious, he should continue to attack Goguryi on a small scale and many times.

Even though Goguryi had 600,000 troops and millions of people, the scale was huge, but after all, it was not as large as the Central Plains.

Sitting on a huge volume, even if he fights for time, it is impossible for Goguryi to surpass the Central Plains.

From the time of Emperor Wen of Sui, there should have been a continuous small-scale infiltration of Gaoguryi, constantly killing their population, plundering their grain and grass, and harassing their borders, so that they could live in peace for a day.

Counterattack?

Yes.

Just let them attack, and the Sui army didn't attack, so they directly stuck to the pass and counterattacked.

The defender always had the advantage over the attacker, and with the transportation conditions in the northeast at that time, no matter which side launched a large-scale attack, it would have to bear a considerable financial burden.

The size of Goguryeo was not as good as that of the Sui Empire, so let it attack and let it counterattack on a large scale, and the Sui army would only hold on to it and refuse to attack.

How long does Goguryi last?

How long can you play?

Even if the two sides attacked each other and played small-scale attack tactics, the Sui Empire also had the advantage, because even if North China could not produce with peace of mind, the rest of the vast region could still produce with peace of mind.

Gao Guli was different, in such a large place, the Sui army's attack covered a little more, which could have a more serious impact on their production.

If you don't see results in three or five years, what about ten years?

Many wars in ancient times were not won or lost in one battle, but through continuous small-scale victories on multiple battlefields, and the accumulation of quantitative changes to qualitative changes, so as to truly establish the victory.

Don't look down on small victories, don't look down on small-scale guerrilla warfare, even if a guerrilla war can only kill three or five enemies, a hundred times can kill three or five hundred, a thousand times can kill three or five thousand, and ten thousand times can kill thirty or fifty thousand.

The same is true for dealing with Xianbei, although the Guo Wei Empire has the upper hand, it is difficult to defeat them in one go.

Zhang Fei's continuous activity after guarding the northern Xinjiang inspired Guo Peng.

So he liberated Zhang Fei's shackles and let Zhang Fei constantly lead troops to make trouble at the border, attack Xianbei, and constantly bleed Xianbei people.

Zhang Fei's bloodletting operation for several years was very effective, so that the Xianbei people could not develop and grow when Guo Peng had no time to go north in the unification war.

After Guo Peng unified the whole country and even defeated the Gongsun clan and returned to the Western Regions, the Xianbei people were unable to move south to establish a strategic advantage over the Wei Empire.

At the moment, the Wei Empire is completely ready to do it.

When the bloodletting is put to a certain extent, the enemy has weakened to a certain extent, and your own preparations are about the same, you can pick up the guy and go up to the decisive battle.

Although it is necessary to have a continuous bloodletting, it is not enough to only bleed without taking a knife and stabbing the last one.

It's the final harvest season, after six or seven years of preparation.

In order to implement Guo Peng's grand strategy, Guo Jia also returned to the staff platform from the Shouyang Mountain Lecture Hall, and presided over a joint meeting attended by more than 100 staff officers with Xi Zhong, and conducted a brainstorming.

How to divide the Wei army and attack together, how to encircle and annihilate the Xianbei living forces, how not to give Xianbei the opportunity to flee north or west, etc.

They took out the old strategic example of Emperor Wu of the Han Dynasty to launch the decisive battle of Mobei as evidence, and demonstrated how correct their strategic direction was.

said how Emperor Wu of the Han Dynasty attacked the Xiongnu in three ways and won the decisive battle of Mobei.

At that time, the Han army was still a little unfamiliar with the grassland road, but now, through long-term business, the Wei people have basically figured out the road on the grassland and how to reach the destination, and there will definitely not be the situation of getting lost and missing the time of the year.

The route of the march is certain, and there will be no mistakes or omissions.

Judging from the current information, Mobei Xianbei has been divided into two forces, one belongs to Fu Luohan and the other belongs to Su Li.

They were all survivors of Guo Peng's Northern Expedition to the Battle of Xianbei Wangting in Danhan Mountain.

In that battle, Guo Peng killed the main leaders of Xianbei, Kirbineng and Budugen, eliminated many Xianbei leaders, and severely damaged Monan Xianbei.

But because Guo Peng didn't think about expanding the results too much, and he didn't have the strength and reserves to expand the results, he gave them the opportunity to flee north in time.

So Guo Peng was also helpless at that time, and he had no way to continue the expedition.

Fu Luohan and Su Li each controlled the power of Mobei Xianbei, and the two were evenly matched, and they were very unpeaceful with each other, and there were often fights.

There were many Xianbei tribes who fled to Mobei, and Fu Luohan and Su Li relied on their own advantages to constantly annex them and expand themselves, and in the end, the two sides were still facing each other.

Because of the strength of the Wei Empire, they did not dare to plunder south, so they could only attack each other and seize each other's survival materials for their own use.

But because they are equal, no one can help the other, and they can maintain a delicate balance in the midst of fighting each other.

According to the intelligence, Fu Luo Han has more than 50,000 string-controlling knights, and Suri has more than 40,000 string-controlling knights.

So the current population of Xianbei is about 500,000.

There will be no more, more will not be able to feed, it will always be consumed by the war between the two sides.

For Guo Peng, what he had to face was Xianbei's last resistance military force, about 90,000 people.

If the army is further expanded, it is not impossible to exceed 100,000 in extreme cases, and reach the size of about 150,000 combatants.

However, in this way, it is difficult to say about the military quality and combat effectiveness of the Xianbei fighters.

Guo Peng prepared to launch a cavalry of about 150,000 to 200,000 to attack Xianbei in the north.

Mobei Xianbei's current power is completely insufficient to make the Wei Empire break its bones.

And the reason why Guo Peng wants to mobilize on such a large scale is also to annex the other party in one go, do his best, and directly start to build a desert animal husbandry economic zone, the plan is very big, not only to completely eliminate the enemy of Xianbei.

Therefore, in order to exterminate Xianbei and erase Xianbei from history, it is understandable to dispatch an army of this size.

In this case, even if Fu Luohan and Su Li urgently joined forces to fight against the Wei army, they were indeed not the opponents of the Wei army.

Strategic victory is inevitable, tactical implementation is the key, Xi Zhong and Guo Jia led the staff desk team to summarize more than a dozen plans for the division of troops and joint attacks, and handed them to Guo Peng for review, Guo Peng looked at one of the plans.

Following the tactics of Emperor Wu of the Han Dynasty, he marched in three ways, and the target was the area of Wolf Juxu Mountain.

According to intelligence, the political and military centers of Suli and Fuluohan are now in the area of Wolf Juxu Mountain.

Probably because he felt that Wolf Juxu Mountain was far enough away and was not within the range of the Wei army's attack, and the environment here was almost good and could survive.

And more importantly, this is the location of the former Xiongnu royal court, and it is quite practical to occupy this place.

Both Fu Luo Han and Su Li want to be the only king of Xianbei, so they have to fight each other to see who can defeat each other and occupy the Xiongnu royal court, and who can become the only king of Xianbei.

The Wei army basically aimed at Wolf Juxu Mountain, attacked in three directions, and leveled Xianbei in one fell swoop.

PS: It's shorter, forgive me, and the rest will be more tomorrow.
