The impact formation launched by the serial heavy cavalry towards the soldiers and horses of the Xia army on the riverside was basically pushed over by the fish scale formation gathered by one squad, and the Xia army, which encountered a surprise attack by the enemy and the formation was routed and morale was loose, naturally did not have time to put on a posture of fighting against the opponent's heavy cavalry.

As the rolling torrent crushed away from the oblique side, the sharp blades accompanied by huge inertia had suddenly swept through the chaotic array of the Xia army, and in the continuous miserable howl, the Xia soldiers fell down in an instant. In the rear, there were also a large number of horse infantry soldiers rubbing shoulders one after another, crowded into a ball, and the groups of soldiers were forced into the river. How can you organize an effective counterattack when you can't perform basic actions in a narrow space?

The chain of heavy cavalry only charged once, and inflicted heavy casualties on the Xia army. However, the unstoppable heavy armored cavalry rushed towards the Xia army formation from the oblique side, and the formation immediately circled again, turning the horse's head again at a distance of two or three hundred steps in front of the Xia army's formation, gathering in formation, and preparing to launch the second and third wave of charges......

Shuo Feng howled angrily, kicked the snow and sighed, but seeing the seven stars playing the soap robe hunting and dancing, some Song Jiang waved the water-milled eight-edged steel whip in his hand, and forcibly swung away the long knife chopped by the stubborn Xia army general in front of him, and the steel whip in his other hand swung violently, smashing heavily on the head of the Xia army cavalry general, and hit him so that his eyes bulged out, and his brain burst to death!

This member led a chain of iron cavalry to charge the Xia army, and the fierce general of the Song army, who led the heavy cavalry to suppress the enemy's position, was naturally the double whip who led his troops to the border of Suide Prefecture for a short time. Originally, Hu Yanzhuo and his best friends Han Tao and Peng Xi led their troops to stop together, and on the way to the border military village to take up his post, he had to report to the military officials sent by Xiao Tang that the Song army troops who were now on standby in Suidezhou, Yan'an Prefecture, and Baoan Prefecture must listen to his orders, and also ordered Hu Yanzhuo to quickly lead his troops to reroute eastward and enter the territory of Xia to assist other Song army troops to intercept the enemy troops rushing to the aid of Yinzhou City.

Since it was a military order sent by Xiao Tang, Hu Yanzhuo, Han Tao, Peng Xi and other generals naturally didn't say a word, and immediately galloped away in the direction of the Wuding River Valley in Xia according to the military order. The soldiers and horses of the Xia army, who were attacked by the half-crossing, could not open their formation, and naturally fell into chaos under the alternating blows of the Song army's crossbowmen and chain horses.

"Huyan is under control, the Xia thieves who crossed the river have almost been slaughtered, according to Xiao Jieshuai's orders, we must also evacuate here as soon as possible."

Hu Yanzhuo heard Peng Xi shouting at him not far behind him, and his eyes glanced at the Xia soldiers and horses on the other side of the river. Seeing that those Xia army troops saw the rescue of their own soldiers and horses, and were worried that there were other Song army ambushes around them, they had to retreat slowly at this time.

Hu Yanzhuo saw that there was a high-spirited smile on his face, and he immediately raised the steel whip in his hand and shouted loudly: "Collect the troops!" ”

The soldiers of the Song Army and the Mabu Army who had set up an ambush heard the order and began to evacuate to the southeast in an orderly manner. The red blood stains in the surging Wuding River have not yet disappeared, and the dead corpses are pillows and blood flowing in a corner of the riverside, and the thick smell of blood fills the air in the battlefield where no one cleans up, and under the afterglow of the sunset, it adds endless desolation and desolation to the scene of this corpse mountain and blood river......

Poor and uncertain riverside bones, like a person in a spring boudoir dream.

In the first battle of Wudinghe, the Song army won a complete victory, killing more than 5,000 enemies. In the following days, the Zhulu Song army sent by Xiao Tang launched an ambush battle against two Xia army soldiers and horses that rushed to Yinzhou. From the beginning of Xiao Tang's gathering of troops and horses to attack Yinzhou City, to the dispatch of troops to intercept the soldiers and horses allocated by other military offices of the Xia army, the tactics adopted were very typical siege and reinforcements.

However, besieging the city to send reinforcements is not a rare tactic, in the classic examples of previous dynasties, one of the 28 generals of Yuntai, Geng Yi, a hero of the Eastern Han Dynasty, once used it to defeat the warlord Zhang Bu, who divided the twelve counties of Qidi; Li Shimin led the Tang army to besiege Luoyang City occupied by Wang Shichong, and also used it when he defeated the 100,000 army led by Dou Jiande at Hugao Pass; During the previous attacks with the Great Song Dynasty, the Xia army also used this tactic handy.

Therefore, not only the Xia army stationed in other military states, but even the defenders in Yinzhou City saw that the Song army was besieging and not attacking, but instead planted antlers to resist horses, dug trenches and built camps. Especially when the generals of the Xia army in the city noticed the frequent movement of the Song army troops besieging the city, and the Song army in the village did not increase the troops but only transferred them to other places every day, they immediately realized that the Song army set up camp under the city, and it must be to use Yinzhou as a bait to induce the Xia army troops to send troops from other places to rescue, and then ambush and annihilate their own reinforcements with the troops deployed in advance.

Since the strategic intentions of the enemy army are known, and now the number of Song troops under the city is decreasing day by day, some people in the Xia army in Yinzhou City immediately proposed to the defender that he might as well wait until late at night to attack the enemy camp, which can not only destroy the fortifications and camps under the Song army, but also can severely defeat the enemy army to greatly boost the morale of the soldiers and horses in the city, and then wait for the defenders and reinforcements to join forces and attack the Song army that is at a disadvantage, not only the siege of Yinzhou can be solved, but also after the defeat of the Song army on the eastern front, narrow Yuwei advanced eastward to conquer several military villages in Suide Prefecture in the Song realm. Stick a knife in the rear of the enemy.

Since the Song army's attention is not on attacking Yinzhou, and the number of soldiers and horses of the Song army does not occupy much advantage at present, as long as the surprise attack goes straight into the Chinese army to kill the main general of the Song army, the soldiers and horses of each department will inevitably be in chaos and have no intention of fighting.

At the end of the night, in the dead of night, under the starry sky, the surprise attack army in Yinzhou City was ready to stop, and the first to sneak out of the city, covering the Song army camp stationed in the military Jian also sent a signal in the direction of the city, Yinzhou City Xia Army General immediately ordered someone to quietly open the city gate, and personally led 5,000 soldiers to sneak into the night, like a group of wolves foraging in the middle of the night swept towards the Song army camp......

"Whoever uses a plan can do it alone, but there must be a number of plans. Therefore, those who make good use of soldiers, luck must prevent losses, and plan to change, the mastermind needs to predict the changes in the battle situation, and set up a strategy in advance to deal with it, so that the enemy can not be guarded against, and will eventually be hit. ”

At this time, in a camp tent about three miles away from the east gate of Yinzhou City, Xiao Tang had already heard the military officials come to report that there was a change at the gate of Yinzhou City.

At this time, Xiao Tang saw Xu Guanzhong, Xiao Jiasui and other brothers pacing into the camp, and several people bowed to each other like a spirit, and then Xiao Tang said to Xu Guanzhong: "The night attack is to surprise and attack it unprepared, once the trick is discovered, it will cause the morale of their own soldiers and horses to collapse...... It's all down to your scheming and accurate prediction of the enemy's movements. ”
