Combining vertical and horizontal forces has always been the most practical and useful military strategy.
It's just that when you use means to plot against others.
Others may also be plotting against you.
The so-called mantis stalks the cicada, but the oriole is behind and doesn't care.
The land of Hebei, east of Liao River.
Whether it is Goguryeo or the Goryeo people, they may never change their nature of not forgetting to eat but not to fight.
Seeing the suffocatingly powerful Central Plains Dynasty in chaos, the king of Goryeo: Gao Jianwu's thoughts slowly came to life.
However, this time of work is still a matter of life. He suffered a lot from Yang Guang before!
Now I want to take advantage of this opportunity, but I am afraid of being caught and rubbed on the ground again...
So after enduring it for several years, I recently made up my mind and decided to send troops out to test it out.
Like a monkey stealing rice, he tried many times on the edge of the Liao River. When Gao Jianwu realized that no one seemed to care about him, he confidently raised his troops and crossed the Liao River in an attempt to occupy the land west of the Liao River.
(Insert a sentence here: The real three conquests of Emperor Sui Yang of Goguryeo in history. Although they all ended in failure, the real failure was only the first conquest. The other two were all because they failed to achieve the expected strategic goals. , and was judged as a failure by later generations.
When Goguryeo was conquered, the Sui Dynasty was at its strongest at that time. Because of this, Yang Guangcai was arrogant and arrogant, which led to major strategic mistakes, causing the Sui Dynasty to lose millions of soldiers and countless weapons and equipment!
However, even in the face of such huge losses, the rich and powerful Sui Dynasty could still afford it! So soon, there was the second expedition to Goguryeo.
The process of the Second Conquest of Goguryeo was relatively simple.
Sui Jun learned the lesson from the last time and fought steadily. This time he immediately beat the man with a stick and called him father and mother!
Just when the Sui army was about to capture Liaodong City and destroy its ancestral temple, Yang Xuangan, the son of Yang Su in Sui Dynasty, suddenly took the opportunity to rebel!
This forced Yang Guang to give up his upcoming victory and return home in a hurry.
Therefore, the failure this time was just that the strategic significance was not achieved, and there was no reason for the defeat.
And because the stick was so badly beaten this time, when Yang Guang attacked Goguryeo for the third time, before Yang Guang could send troops, Goguryeo was so frightened that he ran over and surrendered.
In this regard, Yang Guang, who was so happy about his success, naturally accepted it with joy.
However, there were differences between the two parties regarding the matter of allowing Gao Jianwu to come to Beijing to declare himself a minister and pay tribute. Therefore, this time, the expected goal was not achieved and was also judged to have failed.
To sum up, this is the so-called third expedition to Goguryeo. It ended without even fighting...)
After discovering that no one was taking care of them, the Goguryeo people were overjoyed and set out from Liao River and headed southwest.
In the early days, they really took advantage, because the places they invaded were remote and remote areas, and no one cared about them, so they succeeded one after another, and their arrogance became more and more arrogant!
Until their claws reached Dou Jiande's territory...
I want to ask who Dou Jiande is? He is definitely the number one expert, the kind who truly starts from scratch and does not rely on anyone!
Generally speaking, people like this cannot be offended!
Such as Liu Bang, such as Zhu Yuanzhang!
Ruthless people like them may be able to tolerate Han people attacking each other, but they absolutely cannot tolerate outsiders taking advantage of them!
To use a popular saying, no matter whether the meat is rotten in the pot or in the bowl, it will always be theirs!
But you want to reach out for a chopstick?
Sorry, not only will I not give you the meat, but I will also have to chop off the hand holding the chopsticks!
Goguryeo, which has always been sneaky in everything they do, never thought they would meet such a powerful figure!
The result is not mentioned. As soon as they arrived at the edge of Hebei, Dou Jiande immediately caught them and cut them to pieces. The cuts were painful...
These Korean stickmen all hated their parents for not having two legs, so they were beaten to the point of fleeing back to Liaodong, even to the point of being beaten to death without even daring to show their heads!
In this way, Dou Jiande, who had returned from victory, on his way back to the army, with the power of victory, wiped out Luo Yi in Youzhou in one fell swoop.
At this point, Hebei and the land of Youzhou were all under the ownership of Dou Jiande, and their sharpness was unparalleled for a while.
There is a saying in the art of war: if you fight against the enemy, you will be able to secure the enemy within!
Now that the situation was peaceful, Dou Jiande turned his attention to Li Tang and Wang Shichong again.
So when Wang Shichong's letter asking for help came into his hands, Dou Jiande had already known everything about his battle with Li Shimin.
Rescue Wang Shichong?
Of course we need to save him! After all, he was finished, and he would have to face the rising Tang Dynasty! The term "lips are dead and teeth are cold" is really not just talk!
Save, we must save!
But how and when should we save it? This is an issue worthy of discussion.
So when he received Wang Shichong's letter, Dou Jiande immediately organized his staff to analyze the current situation bit by bit, and then wrote back to Wang Shichong.
As for what was written in the reply, what agreement did Dou Jiande and Wang Shichong reach in secret? The Tang Dynasty here doesn’t know anything about it!
Even Xiao Han, who knew something about this, had no time to think about these "little things".
Instead, he wanted to imitate Wang Shichong and decided to build a hard shell to protect himself.
Inside Luokou City.
With tens of thousands of people working non-stop day and night, it only took more than half a month to build a city wall that was far more dangerous and taller than before and was firmly stuck at the mountain pass.
The entire city wall is only a little over a mile long, but more than three feet high.
The walls were all made of a mixture of boulders and cement. After they were built, they were smashed with heavy hammers. Except for a small pit, not even a single crack could be found!
This level of solidity definitely exceeds that of most buildings in the world today.
"Pour them all with water, don't leave anything out!"
A young team member was walking on top of the busy city wall, shouting and helping his men pour a bucket full of water down the wall.
Clear water flowed happily along the city wall. The gray cement immediately turned dark brown after being stained with water. At the same time, a series of small bubbles appeared on its surface as if it could drink water.
Seeing this magical scene, Cheng Yaojin immediately stopped and asked Xiao Han who was walking in front in confusion: "Hey? Xiao Han, what are you doing? Drink water for the city wall."
Xiao Han didn't even bother to look back, rolled his eyes and said: "Give the city wall water? Am I crazy? Or are you crazy?!"
"Then what are they doing?" Cheng Yaojin asked Xiao Han strangely, pointing at the soldiers who were still pouring water.
Xiao Han chuckled, leaned aside first, and let a group of soldiers carrying buckets pass, and then said to Cheng Yaojin: "This is because the weather has been too hot recently, and I am afraid that the cement on the city wall will dry too quickly and crack. Come on, so we have to splash water! Hey, if you haven’t repaired the city wall, are you going to go out and pacify the surrounding areas? Why haven’t you done anything yet?”
