It is said that Jieli Khan led 200,000 troops and 20,000 horses with Liang Division, and went straight to Chang'an without attacking the city all the way, and divided troops all the way to rob and sweep the countryside, but the Tang Dynasty had already fortified the walls and cleared the wilderness, and the Turks basically did not grab anything all the way, let alone food.

Wei Chi Gong led the troops all the way to disturb the attack, the 10,000 cavalry led by Yu Chi Gong are all long-trained elites, although they can't compete with the Turks on horses, but the Tang army is carrying a crossbow, no need to pull the bow and shoot arrows, you can put the crossbow while rushing, and stay close to the horse plastic, spear charge, so generally the same strength Turks are not opponents.

The Turks divided their troops to rob, and Wei Chigong divided the troops into several teams to eat small troops, and tired the Turks day and night, but he couldn't do it, so he only scored 30,000 soldiers to stare at Wei Chigong and make him unable to move.

Li Jing divided his men and horses to evacuate the people, fortified the wall and cleared the wilderness, and on the other hand, he dug pits and set traps along the way to delay the Turks, and slowly retreated, after all, the Turks had more than 200,000 cavalry, and the field battle could not be defeated, on the one hand, the Turks did not attack the city, and went straight to Chang'an, so there was no way to use the city to consume them.

On April 5, after nearly a month's march, the Turks still approached Chang'an, Li Jing led 90,000 troops to defend Weishui, Li Shimin personally led Liu Hongji, and Chai Shao led 60,000 soldiers and horses left in Chang'an to support Li Jing, and the two sides held each other across the river.

On the same day, Feng Daiwen led his troops to catch up with Qin Qiong and others, and after the convergence, the number of military horses reached 75,000, and more than 70,000 horses, almost one horse per person.

On April 6, the Turks invited to fight, a total of 72 grassland warriors, Cheng Biting Jin killed 11 people in a row, Liu Hongji killed 5 people in a row, Chai Shaobi killed 6 people with arrows, and was shot in the shoulder, Hou Junji killed 8 people, Zhang Gongjin killed 9 people, Cheng Chumo, Cheng Chubi, Yu Chi Baolin, Zhang Shanfeng four small battles and killed 12 people, Xi Junmai, who was left by Feng Daiwen to guard Feng Daizhi, couldn't help but fight, and killed 21 people with people and horses on foot, killing a total of 18 generals, 7 tribal leaders, and 47 warriors.

Jieli Lao was ashamed and angry, ordered a strong attack, the two sides fought a bloody battle around several bridges for a day, the Turks were killed and wounded thousands, and had no choice but to retreat to the barracks, for a while the Turks had no morale, no fighting spirit, the Turks are the steppe peoples, the most worshipping the strong, seeing that the warriors of all ethnic groups were killed, there were still dare to fight.

The Turkic battalion, "Khan should withdraw his troops, there is not much food and grass left." A tribal leader suggested to Jieli.

"Yes, Khan, you can go to Lingzhou and rob Shengzhou!" Another tribal leader hurriedly chimed in; After all, the Turks are all for robbery to the Central Plains, this time did not grab a lot of death, seeing that Chang'an can not attack many tribes want to withdraw their troops, after all, in the spring they still want to plant barley, many people think that the grassland people eat meat is actually not, cattle and sheep are still very valuable food for them, generally not very old do not kill, generally eat barley, drink milk, goat's milk, so the Turks need to fight the grain and grass are rarely their own barley, but the war horses need fine food, long-term war horses eat grass, Not only will it lose fat, but it will also have diarrhea, for ancient times, diarrhea will kill people, not to mention animals, war horses will not adapt to the water and soil, in history, Li Shimin died a lot of war horses when he played Goguryi, and died of cold disease.

"No, we have arrived in Chang'an, we came so suddenly this time, Datang must not be prepared, looking at the crowd on the other side, it must be the people pretending, saying that when the Turki Khan arrives, we will have more than 300,000 troops, what are you afraid of, tell you, Youzhou Luo Yi has already contacted me, this time we will raise troops together, then Li Shimin Xiaoer will inevitably seek peace, anyway, the bridgehead is only so wide, each of your tribes enters separately every day, this time you divide the spoils into 5 percent, and the others go to other places on both sides to see if they can cross the river, Liang Shidu, Your men find a way to build bridges. Jieli promised a heavy reward while arranging the task. Liang Shidu dared to disobey there, so he had to take his own headquarters to find a place to cut wood and build a pontoon bridge.

On the seventh day of the fourth month, the Turkic attack killed 3,000 and the Tang Dynasty 800.

On the eighth day of the fourth month, Li Jing discovered the Turkic intentions, divided Zhang Gongjin and Chai Shao to defend both sides, and Cheng Biting Jin and Liu Hongji to patrol.

On the ninth day of April, the tenth day of April, the Turks were attacking continuously, with thousands of casualties every day, and the progress on both sides was not smooth, the Liang division secretly built a pontoon bridge, which was discovered by Cheng Yanjin, and a half crossed and attacked, more than 5,000 people fell into the water and fed Wang Ba, and burned the pontoon bridge.

"Khan, I haven't received a message from the Tuli Khan for many days, and Luo Yina doesn't know how the progress is, so it's better to send someone to talk to Li Shimin, as long as they pay for food and grass, we will withdraw our troops!" The traitor Zhao Deyan said to Jieli's suggestion. Zhao Deyan was originally a scholar of the Sui Dynasty, but because he was dissatisfied with the Sui Dynasty officials' application for the Turkic examination, he had always been the military advisor of Jieli Khan.

'Nice! Good idea, send someone to do it immediately, and continue to attack tomorrow to put pressure on them. Jieli immediately agreed.

"Haha, it seems that Jieli wants to retire, what do you think, pharmacist!" Li Shimin refused Jieli's request, looked at the letter written by Jieli and handed it to Li Jing and asked.

"Yes, the sage is wise, it seems that Jieli really wants to withdraw from the army, his reinforcements have not arrived, although he has not received the news, but he also obviously feels bad, but he doesn't know that our Datang side knew that his reinforcements were all wiped out two days earlier, and Li Ji and others are almost encircled." Li Jing was rarely relaxed and explained with a smile.

"It's a pity that I can't kill Jieli this time!" Li Shimin slapped his palms and said fiercely.

Li Shimin is quite hateful to the Turks, and has given gifts to the Turks since Li Yuan raised his troops, and the Turks have always supported Liang Shidu and others to trouble the Tang Dynasty and prevent Li Tang from unifying the world.

"Why should the saint be upset, at most in two or three years, we will have the strength to destroy the Turks." Li Jing, as an excellent military commander, still did not understand Li Shimin's strategic intentions, and let Jieli go back, after this defeat, the grassland tribes would inevitably no longer submit to his command, and then the grassland would definitely be in turmoil, just taking the opportunity to consume the Turkic strength and lay the foundation for future wars.

"Holy! Jiang Guogong led the large and small ships in Luoyang to arrive soon, and they could destroy the Turks in two days, and only Jieli would be allowed to go back when the time came. Li Jing smiled at Li Shimin and said with relief.

Li Shimin couldn't help laughing happily when he thought of Jieli riding alone and fleeing back to the grassland in embarrassment, obviously the evil anger in his heart disappeared a lot.
