To the north of Xinping County, in the boundless wilderness, the main force of the 80,000 Sui army is slowly approaching, just as Li Shimin put the most elite 50,000 Tang troops by his side, the 80,000 troops brought by Yang Yuanqing are also the most elite Sui army, including 6,000 Modao heavy armored infantry and 5,000 heavy armored cavalry.

The large camp of the Tang army stands on a slightly raised high ground, with a radius of about ten miles, a small river flows through the left camp, the large camp is a board wall structure, about two zhang high, and the soldiers patrol back and forth on the board wall.

On the high board wall, Li Xuanba, the king of Zhao, and the general Wei Chi Gong were looking at the Sui army camp five miles away in the distance, under the clear sky, they could see very clearly, the Sui army soldiers were busy building the board wall, they had not yet completed the construction of the camp.

"Why don't you rush up and beat them up?"

Li Xuanba pointed at the camp of the Sui army with a whip, his tone was extremely dissatisfied, since the last time he was injured in the Tiger Pass, he has never had a chance to go to the battlefield, the news of the repeated defeats of the Tang army forced him to go crazy, he was eager to lead an army into Taiyuan, and killed Yang Yuanqing and all the officials of the Sui Dynasty to relieve the hatred in his heart.

But after Li Xiaogong died, Li Xuanba seemed to be a different person, became taciturn, his eyes flashed with hatred from time to time, hatred accumulated in his heart day by day, he was waiting, waiting for the moment of revenge.

At this moment, he saw the camp of the Sui army, the fire of revenge began to burn in his heart, and he could no longer suppress it, he turned his head and ran towards the camp, Wei Chigong was afraid that he would lose, so he also followed.

In the camp, Li Shimin was pondering in front of the sand table, he got the scout information, the Sui army actually only came 80,000 people, obviously there are 150,000 troops, so where did the other 70,000 go? He had a bad feeling in his heart, although there was also a Sui army on the other side of Tongguan Road, and the flags were overwhelming, but Li Shimin thought. This is a bluff by the Sui army, at most only one or two hundred thousand people.

Could it be...... Li Shimin was well aware of the weakness of the Tang army's deployment in Guanzhong, and what he was most worried about was that the defense of Kwantung was weak, and there were only 30,000 troops on the front line of Tongguan and Pujin Pass.

Fang Xuanling next to him saw that Li Shimin's eyes had been staring at Feng Yijun. He understood his concerns, "Your Highness, the lowly position is also worried about the Eastern Front. ”

Li Shimin Huo Di turned around and looked at Fang Xuanling, "Do you also think that Yang Yuanqing will divide his troops and go south to Feng Yi County?"

Fang Xuanling nodded, "The key is that the current commander of the Sui Army is Yang Yuanqing instead of Qin Qiong." Qin Qiong will not divide the eastern front, the eastern front is not his theater of operations, but Yang Yuanqing is different, he is considering the overall situation, if he finds that the eastern front is weak, he will inevitably consider it, and now his troops have been significantly reduced......"

Fang Xuanling didn't say anything, but the meaning was obvious, Yang Yuanqing must have sent troops to the Eastern Front. Li Shimin's eyes showed anxiety that could not be concealed, if the eastern front was broken and the Sui army drove straight into Guanzhong and went straight to Chang'an, then what was the point of him staying here?

It's like a bucket, no matter how strong it is elsewhere, if something goes wrong in one of them, the water in the bucket will run out as well.

"What do you think, sir?" Li Shimin's heart was a little confused. He didn't know what to do.

Fang Xuanling sighed slightly. "There aren't many options out of the equation now, if you have to have a choice. So I can list three strategies. ”

"Sir, please speak"

"The best strategy is for His Highness to fight quickly with the Sui army, defeat Yang Yuanqing's department as soon as possible, and then quickly save the eastern front, the middle strategy is for the Chang'an defenders to attack, send 50,000 troops to reinforce the eastern front, so that the strength of the eastern front will increase to 80,000, which may be able to resist the attack of the clan army on the eastern front, and the next strategy is that the Tang army will abandon Guanzhong on all fronts, withdraw to Chang'an, and hold Chang'an City."

Li Shimin shook his head, "The next policy can't be considered in the first place, although the middle line is the best, but the prince is willing to give in, it is still a problem, not to mention the father's elbow, I estimate that there are at most 30,000 troops, divided into 10,000 to defend Tongguan Road, so the eastern front is only 50,000 troops at most to defend, can it hold on?"

"Your Highness means that you can only choose the best strategy?" Fang Xuanling understood what Li Shimin meant.

Li Shimin's face showed a bitter look, "It should be said that only the best policy is in my hands, but ......"

Li Shimin slowly walked to the door of the big tent, stared at the Sui army camp in the northeast, as if saying to himself, "The decisive battle between the two armies should be based on stability, if you rush to the battle, the gains will outweigh the losses, and eventually lead to defeat, where should I go?"

At this time, he suddenly saw the third brother Xuanba rushing towards the big tent like a gust of wind, no one on both sides could stop him, followed by Wei Chigong, Li Shimin frowned, what happened?

"Don't stop him, let him come directly into the tent," Li Shimin immediately ordered his own soldiers.

After a while, Li Xuanba rushed into the big tent of the Chinese army and shouted loudly: "Second brother, the Sui army is building a big camp, if you don't take this opportunity to attack the Sui army, when will you wait?"

"Don't shout like that"

Li Shimin was extremely displeased and said: "I know whether to attack or not, I don't want you to teach me."

"Your Highness"

Fang Xuanling next to him whispered: "We should understand King Zhao's eagerness."

He was actually hinting to Li Shimin that King Zhao was not very human, don't anger him, Li Shimin nodded, and said to Li Xuan: "Wait a while, I will lead the troops and you to take a look."

At this time, Wei Chigong also entered the camp, and Li Shimin immediately ordered him, "Order 15,000 horses and infantry troops, and go out of the camp to plunder." ”

The critical situation on the Eastern Front made it impossible for Li Shimin to confront the Sui army for a long time, but he did not want to rush into a decisive battle, so he decided to fight a tentative battle with the Sui army first.

The drums of war in the Tang army camp rumbled, the camp gate opened, and groups of cavalry and infantry rushed out of the camp at a rapid pace, waving flags and covering the sky, they quickly sorted out their ranks in the camp and began to march in line towards the Sui army camp.

Although the Sui army camp is still under construction, but the defense is very tight, there are 6,000 cavalry to defend against the Tang army's sneak attack, commanded by Yang Wei, when the Tang army camp war drums sounded, the Sui army sentry immediately raised his head to the sky and blew the horn.

'Woo-'

The horn sounded, 6,000 cavalry rushed out of the camp, under the leadership of Yang Wei, in front of the camp to defend, 6,000 spears brushed the ground and rose, the murderous spirit boiled, and then, the 4,000 heavy crossbow army also rushed out of the camp, raised a giant crossbow in front of the cavalry, and aimed at the slowly approaching Tang army.

Yang Yuanqing has been reported, he immediately led 10,000 horse infantry out of the camp to fight, and the Tang army is just the opposite, Yang Yuanqing is not in a hurry to fight a decisive battle with the Tang army, he is waiting for the change of the battle situation on the Eastern Front.

The Sui army has 150,000 troops on the eastern front, Li Jing, Qin Qiong, and Pei Xingyan are all the main generals, but the main general of the other side is Li Shentong, with only 30,000 troops, even if the troops are increased, it will be at most 50,000 or 60,000 troops, which is far from being able to compete with the Sui army, and it is only a matter of time before the eastern front breaks through.

As long as the Sui army enters the pass from the east road, then Li Shimin will not be able to hold it, and will inevitably withdraw to Chang'an, and at this time, it is a good opportunity for the Sui army to attack on a large scale, even if Li Shimin is resourceful, but the general trend has gone, he has no power to return to the sky.

In this case, Yang Yuanqing did not necessarily use any strange troops, let alone a sneak attack or night battle, as long as he took every step of the way and defended without leakage, Li Shimin would definitely lose this battle.

"Your Highness, the Tang Army seems to have realized the danger on the Eastern Front."

Luo Shixin next to him smiled: "You actually came to the battle so quickly."

Yang Yuanqing watched Tang Jun slowly approach, and shook his head, "The other party only has 10,000 troops, obviously just a temptation, don't fight with them." ”

He immediately shouted: "The cavalry withdraws, and another 3,000 crossbowmen are transferred to suppress the formation."

Yang Yuanqing's military order is like a mountain, although Yang Wei is eager to fight with the Tang army, but he did not dare to disobey the order, led 6,000 cavalry to slowly retreat to the camp, at the same time, 3,000 crossbowmen came out of the camp, deployed behind the giant crossbowmen, raised the crossbow aimed at the Tang army.

At this time, the Tang army had reached two miles away, consisting of 5,000 cavalry and 5,000 infantry, Li Shimin was dressed in golden helmets and armor, holding a wolf's tooth lance, and on both sides of him were also famous generals, Li Xuanba, Wei Chigong, Li Junxian, Lu Zushang, Hou Junji, Liu Hongji and so on.

In contrast, there are not many famous generals around Yang Yuanqing, only Luo Shixin, Yang Wei, Niu Jinda, Xue Wanche, etc., but this also shows that Yang Yuanqing's famous generals have been distributed all over the country, Li Jing, Qin Qiong, Pei Xingyan are on the eastern front, Xu Shiji is on the southern front, Wang Junke is in Bashu, and Xie Yingdeng is in Jingxiang.

Li Shimin stared at the Sui army's formation from afar, and it was obvious that the Sui army deployed a large number of bow and crossbow troops in front, but they didn't want to fight with themselves, which confirmed their guesses even more, and the center of gravity of the Sui army had been placed on the eastern front, and this side became mainly defensive.

"Second brother, let me go and attack the Sui army formation" Li Xuanba held two sledgehammers in his hands, anxious, and shouted for battle.

"Are you made of iron?"

Li Shimin finally couldn't bear it anymore and angrily reprimanded this stupid brother, "The Sui army has seven or eight thousand crossbow arrows, can you dodge?" Shoot you like a hornet's nest and you won't scream. ”

Li Xuanba lowered his head when he was scolded, and Wei Chigong couldn't bear it, so he also stepped forward and said: "Your Highness, if you withdraw the army back to the camp like this, it will inevitably affect morale, it is better to lead an army from the south, attack the Sui army from the south, disperse the Sui army's defense, and then we will attack from the front."

Li Shimin stared at the Sui army for a long time, and finally sighed, "What can we do about the attack, we only have 10,000 troops, can we still defeat the Sui army, if it is not good to send troops, it will shake the army's morale even more." ”

He immediately ordered: "Collect the troops and return to the camp"

At this time, Li Shimin beckoned Liu Hongji and whispered to him: "The main camp of the Sui army is in Luojiao County, and the grain and grass transportation line is long, you can lead 5,000 cavalry to send troops tonight to attack the Sui army's grain and grass transportation line, and if possible, burn the main logistics camp of the Sui army."

Now, Li Shimin can only use strange soldiers to deal with the Sui army, and cutting off the grain and grass logistics of the Sui army may be a way......
