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.
No matter whether it is Goguryeo or the Goryeo people, they may never change their nature of caring about eating rather than fighting.
Seeing the suffocatingly powerful Central Plains dynasty in chaos, Gao Jianwu, the king of Goryeo, began to think slowly.
However, this time of living and breathing, he suffered a lot from Yang Guang's previous losses!
Now I want to take advantage of the opportunity to gain some benefits, 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 Yang of Sui Dynasty on 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 purpose.
, and was judged as a failure by later generations.
When Goguryeo was conquered, the Sui Dynasty was at its most powerful 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 weapons!
However, even in the face of such huge losses, the rich and powerful Sui Dynasty could still afford it! So soon, there was a second conquest of Goguryeo.
The process of the Second Conquest of Goguryeo was relatively simple.
The Sui army learned the lesson from the last time and fought steadily. This time, they immediately beat him 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 the victory he was about to gain 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 blow was so severe this time, when he conquered Goguryeo for the third time, before Yang Guang had time to send troops, Goguryeo was so frightened that he ran over and surrendered.
Yang Guang, who was overjoyed with his success, naturally accepted this 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, so 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...)
The Goguryeo people, who were overjoyed to find that no one was taking care of them, set out from Liao River and headed southwest.
In the early days, they really took advantage, because the places they occupied 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...
If you want to ask Dou Jiande, who is he? He is definitely a powerful person, or someone who truly starts from scratch and does not rely on anyone!
Generally speaking, people like this cannot be messed with!
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 the hand holding the chopsticks will also have to be chopped off!
Goguryeo, which has always been sneaky in everything they do, never thought they would meet such a powerful person!
The result is unknown. As soon as they arrived at the edge of Hebei Province, 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 so hard that they fled 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 his power was unparalleled for a while.
There is a saying in the book of war: if you fight against the outside, you will make sure the inside is safe!
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?
Naturally, he needs to be saved! After all, he is finished, and he will have to face the flourishing Tang Dynasty! The words "dead lips and cold teeth" are really not just words!
To save, to save!
But how to save and when to save? This is a question 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 has no idea!
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 day and night, it only took more than half a month to build a city wall that was far more steep 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 behind!"
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.
The 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 passed a group of soldiers carrying buckets, 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 out too quickly and crack.
Open, so we need to splash water! Hey, after the city wall has been repaired, why don’t you go out and pacify the surrounding area? Why haven’t you taken action yet?”
