Tongguan.

Bai Xiaowen received information from Camille, Ma Chao asked Han Sui to increase his troops, and also sent an envoy to Xiliang to ask the Qiang troops to come to help in the battle.

There is a high-level internal response, which is to save worry and effort.

Bai Xiaowen inspected the geographical map of mountains and rivers, and after reconnoitering the terrain, he decided to still let Cao Ren guard the pass, he led an army of 50,000 to the north, and smuggled Weishui from Pubanjin at night.

It's early spring.

Spring came late in the northern land, Weishui did not thaw, and the ice could barely carry a large army to cross, but it could not be used as a battlefield for fierce battles.

After crossing Kasakatsu, in front of him is Feng Yijun, which is also the right flank of the land of Sanfu.

If you can gain a foothold in the west of Weishui, then you can form a horn attack with the defenders of Tongguan!

Ma Chao's Xiliang Army is also bound to divide its energy to take care of the flanks, making it even more difficult to attack Tongguan.

However, the intelligence work of the Xiliang Army was not bad, Bai Xiaowen led the army to cross at night and was detected by the Xiliang Army in advance.

Ma Chao said excitedly: "This is the destruction of Yuan Xi, I want to raise the army and go to Pubanjin to stop it in person!"

Pang De said: "Yuan's army has recently increased by 40,000 troops, and the army is huge. Although Yuan Xi raised tens of thousands of troops to cross the river, there were still nearly 100,000 horses in Tongguan. Moreover, Yuan Xi is scheming, if all our troops are dispatched and the enemy army in Tongguan attacks and occupies our army's camp, we can only retreat to Chang'an. ”

Ma Chao nodded and said: "It's a pity that the reinforcements from my uncle and Qiang soldiers have not arrived! In this case, Pang De and my brother will guard the camp, and I will personally lead 5,000 elite cavalry to attack Yuan Xi, and we must not let him build a camp! Wait until the reinforcements arrive, and then take advantage of the situation to break the enemy." ”

It can be seen here that the Xiliang Army has no shortcomings as strategists.

If Ma Chao can be decisive and raise a large army to prevent Bai Xiaowen from crossing the river, he will definitely make Bai Xiaowen suffer a defeat.

However, Ma Chao was worried about the safety of the camp, so he left a large group of men and horses to guard against the "unnecessary" Cao army attacking the camp! With only 5,000 cavalry with him, he could only play a harassing role and could not prevent Bai Xiaowen from crossing the river.

Of course, this is also Bai Xiaowen's suspicious tactics that played a role, making Ma Chao and Pang De mistakenly think that there are tens of thousands of troops in Tongguan. In fact, there are only more than 10,000 people under Cao Ren's subordinates in Tongguan now, and they have no ability to threaten Ma's super battalion.

In the battle of Pusakajin, Bai Xiaowen paid a lot of price for crossing the river.

Because of the battle of crossing the river, the vanguard must withstand the enemy's attack, otherwise the front team will retreat, which will inevitably disrupt the formation of the rear team, trample on each other, and most easily lead to a rout.

Ma Chao is also strong, and the lord's skill to charge the formation is a divine skill to destroy the enemy's formation. Yu Ban's big shield soldiers, because of the lack of numbers, were all defeated, fell into the Weishui, and blood stained the ice.

In addition, the ice in Weishui is already very thin, and in the case of the busy army, there are many ice layers on the soles of the feet that break and fall into Weishui. Although with the quality of a spiritual soldier, he will not die if he soaks in the icy water overnight, but after all, he will disrupt the formation and will not be able to participate in the battle.

However, even at a great cost, Bai Xiaowen still managed to cross the Weishui.

Zhang Liao and Xu Huang defeated Ma Chao, and Zhang Xiu and other generals galloped through the chaotic army, gaining time and valuable space for the follow-up troops to cross the river.

Ma Chao saw that the 5,000 iron horsemen were running low, so he collected his troops and returned to the camp. Xiliang Iron Cavalry, really came and went at will, Yuan Jun could only watch Ma Chao go.

However, he said that after Ma Chao returned to the village, he discussed with Pang De: "On the west bank of Weishui, the sand and soil are soft, and it is difficult to build a camp. Our army is recuperating and recuperating, and when the cavalry is dispatched again tomorrow, we will definitely be able to break Yuan's army again. ”

If the infantry army does not rely on the defense of camps and passes, then in the face of cavalry, it is almost a lamb to be slaughtered.

There is no camp in the way, Ma Chao can even lead the iron cavalry, chisel through the formation of the Yuan army, and then turn back and charge again!

......

On Bai Xiaowen's side, after crossing the river, he relied on Weishui to prepare to establish a camp.

Under the excavation, the sand was slack, and it was impossible to set up camp. All the generals had a sad look on their faces.

Bai Xiaowen smiled and invited someone: "This camping is all thanks to the Taoist chief." ”

That person was Ge Xuan.

When the generals saw the monks around the lord appear, they were all skeptical, and they had a little expectation.

Ge Xuan looked confused: "Childe, poor Dao is not a general, how can he know how to set up camp?"

Generals: Meow meow?

Bai Xiaowen smiled: "Did the Daoist Elder forget what I asked you before?"

Ge Xuan said: "Childe just said, ask for a north wind for ten days, and snow overnight." If this is the case, the poor road has already been done. - But what does that have to do with camping?"

Bai Xiaowen said: "The sand is soft and difficult to build. But if you water it with ice water, you can build it and freeze it in the cold, and you can build an ice city overnight!

The generals will be skeptical.

Bai Xiaowen then ordered the sergeant to dig up the soil and water the ice. After a while, the north wind rose strongly, the weather suddenly turned cold, and there were snowflakes.

Just like Bai Xiaowen said, the soft sandy soil is as hard as iron after being poured with ice water and frozen by the cold. Tens of thousands of troops started together, and a camp made of frozen soil was built in less than two hours.

Everyone admired Bai Xiaowen's plan, and even Xun You praised: "Da Sima Zhiluo, it is really given by God, and I can't do it." ”

Bai Xiaowen was cheeky and accepted it calmly.

In fact, this method of moving soil and watering to build a city is the method of Lou Gui adopted by Cao Cao in "Romance of the Three Kingdoms", which was not Bai Xiaowen's first creation.

If it is used here, it still needs Ge Xuan's ability to change the time of day, otherwise with the weather in early spring at this time, it is not so cold, and it will still not be able to build an ice city.

As for Ge Xuan, he didn't have such an ability to defy the sky.

But after he read through the "Taiping Sutra", his Taoist ability has improved again, so he can pray for the ten days of north wind and the night of snow.

In the early morning of the next day, a horse scouting reported that Ma Chao had been built in Yuan's military camp.

Ma Chao didn't believe it, and personally led the troops to watch, and sure enough, he saw a strong city. He was shocked in his heart, looked back at Pang De beside him and said, "Yuan Xi must have the help of ghosts and gods? Otherwise, how could he build a camp of this scale overnight?"

Pound said with a worried face: "Now the enemy army has successfully gained a foothold in the west of Weishui. If we don't break through this camp early, I'm afraid our army will be attacked. ”

Ma Chao nodded in agreement, but he was still worried that the Tongguan garrison would attack the camp, so after weighing it, he left 20,000 troops behind and ordered Ma Dai to guard the camp, and he and Pang De raised the rest of the Xiliang soldiers and horses with 50,000 men and horses to attack the camp that Bai Xiaowen had just built.

Xun Youxian "ambush on all sides" strategy, said: "The lord can send a general to defeat and lead the enemy army to attack our camp, and ambush the soldiers and horses of the four roads to copy the back road." Attacking before and after, Ma Chao will undoubtedly lose. ”
