The body fell to the ground with the dead war horse, and his back hurt on the ground, Zhang Nai couldn't bother to pull his foot out of the stirrup, and looked up with difficulty, and saw that more than 20 cavalrymen fell to the ground like himself, right beside him, the captain of the personal guard pillar lay motionless on the ground, and red blood was flowing out of several small holes in his chest.

Dozens of cavalry were bombarded by tiger squatting artillery, the loss was negligible for the 1,500 cavalry, most of the galloping cavalry did not know that their main general had fallen to the ground, except for some cavalry who were blocked by the fallen men and horses, the other cavalry either crossed the fallen war horses, or galloped past the corpses of the war horses, and continued to rush towards the Xishan army array.

Zhang Nai pulled his feet out of the stirrup with difficulty, and as soon as he sat up, he heard a loud noise one after another, accompanied by a loud noise, as if countless tripwires had been pulled up in front of him, and like a huge wave hitting a mountain cliff, the cavalry running in the front fell to the ground like a wave.

It was not one horse or two horses, but hundreds of cavalry fell at the same time, the cavalry in front fell one after another, and the cavalry galloping behind could no longer dodge, and collided with the people and horses who fell to the ground, the whole cavalry queue was in chaos, and the hundreds of cavalry in the rear forced themselves to pull the war horses, which avoided collisions.

Tiger Squat Cannon! The Xishan Army actually placed so many tiger squatting cannons behind the car formation! Zhang Nai felt his head buzz, and his body shook violently. Although he was young, Zhang Nai had been in the army for more than ten years and was very familiar with all kinds of artillery of the Ming army.

Tiger squat artillery is also often used on the battlefield, but this kind of artillery has a very short range, only three or four hundred meters of range, which is much shorter than ordinary cannons, so many armies do not like to use it. Because on the battlefield, this kind of artillery can only be used when the two sides are in close contact, and such a short distance, which is already within the range of the bow and crossbow, may only need a round of covering arrow rain to kill all the artillery.

At most, one shot will be fired, and the soldiers on both sides will rush together. To really destroy the city and pull out the village, it is still necessary to use Hongyi cannons, and no matter how strong the city wall is, as long as it is constantly bombarded with Hongyi cannons, it can always collapse. However, it was this kind of inconspicuous artillery that played tricks in the hands of the Xishan Army, repelling the enemy with a vehicle formation, placing an artillery array behind the formation, and taking advantage of the dense formation when the enemy attacked, opening artillery bombardment, and a cannon often sprayed out hundreds of small projectiles, and the power was enough to penetrate the heavy armor within two or three hundred meters.

Just five or six tiger squat cannons opened fire one after another, causing casualties to the invading cavalry of three or four hundred cavalry. After the tiger squat cannon was fired one after another, it was another round of fire guns, and more than 200 fire guns were fired one after another, causing another 50 or 60 casualties to the cavalry.

Zhang Nai, who looked at the huge casualties, was stunned, and the remaining reason told him to retreat immediately, he could not break through the Xishan Army's vehicle formation in a short period of time, and continued to fight and wait for the Tiger Squat Cannon to reload its ammunition, it would definitely bring another round of casualties.

Wait, should we wait and send out the cavalry to outflank the rear of the Xishan Army? Zhang Nai hesitated.

"General, look!" One of the surviving guards shouted in panic as he pointed to the distance on his horse.

Zhang Nai grabbed the reins of an empty horse beside him, turned over and jumped on the war horse, and looked in the direction of the guard's finger, and saw a large cloud of smoke and dust rapidly approaching a few miles behind the Xishan military chariot array.

That's the cavalry of the enemy's rescue! Almost instantly, Zhang Nai understood, since the enemy's reinforcements arrived, the outflanked cavalry had no chance, and now there was only one way to retreat.

"Mingjin retreats!" Zhang Nai bit his lower lip, ordered hatefully, turned over the horse's head and took the lead to run back and forth, at this moment his heart was dripping blood!

Seeing the enemy soldiers retreat into the distance all of a sudden, Chen Jianghe's heart suddenly settled.

"Boss, are you okay?" Yu Feng galloped over with his troops, and he was relieved when he saw the enemy soldiers retreating, but when he saw Chen Jianghe covered in blood, his heart was suddenly very nervous.

Yu Feng originally led the team to clear the remaining rebels of the guard, Wu Mengming took 300 people to escort Chongzhen to escape across the canal pontoon, and sent cavalry to report the news, Yu Feng learned that the thief cavalry was chasing over, and the adult's father was leading troops to block, and it was too late to report to Chen Yue in the acropolis, and he came with a quick reinforcement of his cavalry, and some of his cavalry were encircling and suppressing the robbed rebels of the guard, and there were more than 200 people who could be assembled in a hurry. In order to save Chen Jianghe, he couldn't take care of much, and killed him with more than 200 horsemen.

"I'm fine, it's all the blood of the thief, Yu Feng, you came in time! Hahaha. After a fight, although his body was extremely tired, he was refreshed from the inside, and Chen Jianghe laughed.

"Fortunately, the thieves retreated, and if they hold on for a while, I'm afraid things won't be good." Looking back at the retreating enemy cavalry in the rear, Yu Feng said happily that the number of cavalry under his command was much worse than that of the enemy, and if he was fighting, he would definitely suffer a big loss.

"Yes, they have divided a cavalry route to attack us, if we wait for this group of enemies to attack behind us, it will be troublesome." Chen Jianghe agreed. On the left side of the official road where the car formation is located is the canal, and on the right side is a small swamp, which is not conducive to the galloping of the cavalry, Zhang Nai's 1,000 cavalry divided into a flank attack around a few miles away, and before he had time to run to the rear of the car array, he saw Yu Feng's department that came to help, Zhang Nai issued an order to retreat, and he had no choice but to retreat.

"They came too fast to form a full formation. Otherwise, it's easy to get in their way. Jin Xin shook his head and said, the Xishan Army's vehicle formation even blocked the Eight Banners cavalry, not to mention the thief cavalry whose combat strength was inferior.

"Boss, since they retreated, we should also retreat." Jin Xin on the Chenjiang River.

Chen Jianghe nodded when he heard this, glanced at the sunset that was about to set, and said, "Let's also retreat, and strive to rush to the Tianjin Acropolis before dark, but we have to guard against them from sneaking up on us while we are marching." ”

"With me here, don't worry, boss." Yu Feng patted his chest and said.

Under the escort of Yu Feng's 300 cavalry, Jin Xin commanded his subordinates to collect the car formation, simply cleaned up the battlefield, loaded the tiger squat cannon on the car, and continued to march towards the Tianjin Acropolis, walked more than three miles, and crossed the pontoon bridge erected on the North Canal, the sky finally got dark. Perhaps the thieves suffered too many casualties, or perhaps the two days of sleepless pursuit were too tiring, until the whole army crossed the pontoon bridge, and no more intruding cavalry attacked.

After crossing the pontoon bridge, Chen Jianghe decisively ordered to cut the pontoon bridge, since the thief cavalry was chasing, maybe there would be more troops behind, and cutting the pontoon bridge could at least delay the enemy for half a day, and buy time for the Xishan army to retreat from Tianjin.
