This skirmish has nothing to do with the overall situation, Li Shimin went to the Xia army camp to "spread wild", in fact, he wanted to fight psychological warfare with Dou Jiande, he could bring not many people to the camp to show off his might, give the enemy a taste of rumors, and greatly impact Dou Jiande.

Then, Li Shimin wrote an arrogant letter to Dou Jiande: First of all, thank King Huai'an for being captured and received your courtesy, and then thank you for sending back Princess Tong'an. Wang Shichong has recently reconciled with you, but he has repeated many times, and now Wang Shichong's demise is at hand, but he lured King Xia with clever words, so King Xia led the people of the three armies to obey the dispatch, and the military expenses of the daughter were consumed for others in vain, which is really not the best policy. I took a few people to wander around King Xia's camp, and found that King Xia's people were vulnerable, King Xia, you see that you and Wang Shichong haven't been able to see each other, so you have been teased, do you still have the heart to see Wang Shichong? I slightly frustrated your sharpness because I hope you can listen to my advice and don't get involved with Wang Shichong, otherwise you will regret it. ”

Dou Jiande was attacked by Li Shimin like this, it was just the beginning, and in the next month when they held each other, the tiger prison could not be attacked for a long time, and the attack was defeated once, which made the morale of the army very low, plus his supply line, was cut by Li Shimin's generals, which was really worse, causing the soldiers to think about it.

At this time, Dou Jiande's adviser Ling Jing suggested giving up attacking the Tiger Prison, taking advantage of the fact that the Tang army was basically under Luoyang City, and the whole army went straight to Li Tang's base Guanzhong, Li Shimin fell into a dilemma, which had three advantages: First, Guanzhong was like a no-man's land, and he could win without losing anything. Second, along the way, we will open up our territory and recruit troops, and the country's strength will naturally become stronger. The third is that Guanzhong was restrained, and Luoyang was naturally lifted, which was a plan to save Zhao from Wei and Wei.

Ling Jing's strategy was simply amazing, and Dou Jiande immediately adopted it.

But Dou Jiande didn't know that nerve was wrong, and was finally led by Wang Shichong's nose and left, Wang Shichong continued to send people to tell the emergency, Wang Wan and the eldest grandson An Shi were like two mothers-in-law who could sprinkle, crying heartbroken day and night in Dou Jiande, like a mourner, begging Dou Jiande to rescue Luoyang, and at the same time, secretly bribing the generals under Dou Jiande with gold and jade, and letting the generals blow the wind in Dou Jiande's ears. Let him thwart Ling Jing's plan.

The generals saw that Qian was open-minded, so he solemnly said to Dou Jiande, Ling Jing is a scholar, where does he know how to fight, how can he listen to his words?

I don't know if Dou Jiande's ears are soft, or his brain is short-circuited, he actually listened to the words of the generals who didn't care about the political situation for the sake of money.

For this reason, Dou Jiande apologized to Ling Jing: "Now that the morale of the generals is high, take this opportunity to fight a decisive battle, and you will definitely be able to win a big victory, and you can't act according to your suggestions." ”

Ling Jing repeatedly persuaded him that this was the best policy. Dou Jiande was impatient when he heard this, and ordered someone to put him out and throw him out of the door.

Ling Jing's heart was broken to the extreme, such a good plan was not needed.

That's it, that's it...... It's better to go home with peace of mind and watch Dou Jiande die by himself!

Dou Jiande's wife, Cao Shi, is an understanding person, and said reasonably: "The plan of sacrificing wine and respecting Ling Jing is very right, and it should be obeyed." Now the king should be empty of the Tang State, and should use all our forces to seize Shanbei and Dai, Fen, Jin and other places, and then use the Turkic army to plunder Guanzhong to the west, the Tang army will inevitably return to Guanzhong to save itself, and still worry about the siege of Zheng Guo's eastern capital? If we stop here, we will lose our morale and run out of food, and we will be in a very passive position, and if we clash head-on with the Tang Army in this situation, we will suffer. ”
