Li Shimin began to be a little panicked in his heart, even the gunpowder he had the most high hopes for did not achieve the expected effect, how to conquer this impregnable Anshi City now? After seeing the efficiency of gunpowder siege, the soldiers from the emperor to the lower levels were reluctant to return to the old way of filling with human lives.

Just when Li Shimin was anxious in his heart, the southern gate of Anshi City suddenly opened, and the hanging suspension bridge was quickly lowered, and a heavily armed cavalry team rushed out of the doorway.

This cavalry rushed out of the city gate very quickly, and they appeared at a good time, it was when the Tang officers and soldiers were shocked by the scene that the gunpowder just now did not blow up the city gate, and when the generals of the Tang army in the south found out and ordered resistance, this cavalry had already rushed out of the drawbridge and charged them.

The south was originally a feint, and the troops were insufficient, not to mention that this cavalry rushed too fast, and before the Tang army could react, the Goguryeo cavalry had broken through the Tang army's defensive line, like a sharp knife quickly cutting through tofu.

The chaotic scene also alarmed Li Shimin in the Chinese army, and when he saw the people outside the southern city wall shouting and neighing, and the monarchs and ministers looked at it, the Goguryeo cavalry had broken through the formation of the Tang army in the south and went straight to the Chinese army.

The change of the Goguryeo cavalry made the monarchs and ministers present feel stunned, looking at the murderous appearance of the thousands of cavalry rushing at him, Li Shimin sneered: "Hehe, Yang Wanchun is ready to kill the general and capture the flag, his heart is not small, but to take my life, it depends on whether you have the ability!" ”

The large array of the Chinese army is still five miles away from the front army, and this position is already very high. As soon as the Goguryeo cavalry turned around, Zhang Jian immediately ordered: "Immediately order the forward cavalry to go out to meet the enemy head-on, and outflank the left and right flanks with infantry, and we must annihilate this team in the front camp, so as not to disturb Your Majesty!" ”

The forward cavalry immediately dispatched after receiving the order, and more than 10,000 people rushed towards the Goguryeo army like a tide.

Seeing that the distance between the two armies was getting closer and closer, Li Shimin and the others were waiting for the exciting collision, when a sharp whistle suddenly came out of the Goguryeo cavalry, and then thousands of people turned at the same time, turned a corner in front of the Tang cavalry formation, and rushed towards the east gate instead.

Seeing this change, he immediately reacted and said loudly: "Their real target is the firearms battalion soldiers!" The cavalry of the front battalion immediately accelerated to follow! ”

Only then did the Tang monarchs and ministers who had been in battle for a long time understand Yang Wanchun's true intention, which was to eliminate the two thousand firearms battalion soldiers armed to the teeth.

In order to defend Anshi City, Yang Wanchun spent a lot of energy to find out the news of the Tang Army in the early stage, and took the following staff to deduce, and also rehearsed the Tang Army's offensive routine, and now the situation is basically within the scope of their discussion.

Li Shimin's face was flushed, his teeth were trembling, and his heart was full of shame and anger. He boasted that he was also proficient in warfare, but today he was toyed with by Yang Wanchun, and he had never experienced the humiliation of being led by the nose and played.

"The cavalry will catch up with me, and they must all be wiped out, and not a single one will be left alive!" Li Shimin gritted his teeth and said.

Although His Majesty's order was issued, the situation on the battlefield was not optimistic, and there was no way for the Tang Army cavalry battalion to suddenly change direction, and when the war horses were galloping at high speed, changing directions at this time would cause great confusion.

The Tang cavalry lowered their horses a little, then turned their horses' heads around, and after a large circle, they lined up to pursue the Goguryeo army, at which time the Goguryeo cavalry had left the Tang army behind and went straight to the firearms battalion soldiers under the city walls.

Seeing thousands of enemy troops coming straight to him, the more than 2,000 soldiers of the firearms battalion under the city wall began to panic, because the grenades were all burned when the Goguryeo stole the camp, these soldiers are now using broadswords and spears, ready to use the invulnerable armor to push the Goguryeo back when the city is broken, and now let them face the charging cavalry a little weak.

As the rumbling horses' hooves got closer and closer, they rushed in front of them in the blink of an eye. The high-speed sprinting war horse galloped, the spear was held flat beside the horse, and then there was a loud noise, and there were screams of people and horses, the soldiers of the firearms battalion in the front were knocked away by the horses, and the soldiers in the middle were knocked to the ground by the horses, and after a round of charge, the soldiers of the firearms battalion were lying on the ground because the armor was too heavy, and they struggled to stand up, but found that it was in vain.

The Tang cavalry watched the enemy slaughter there, and urged their horses forward in a hurry, but the enemy cavalry had already turned their horses' heads and started the second round of sprints, they threw away their spears, took out bulging leather bags from their horses, and then shouted and poured the fire oil on the armor of the firearms battalion soldiers, and the last row of Goguryeo cavalry threw the fire folds into the crowd, only to see the fireballs rushing into the sky, and the whole field was engulfed in flames.

At this time, the cavalry of the Tang Army arrived in a hurry, and when they were ready to start the attack, they only heard another sharp whistle from the enemy, and everyone turned around again and rushed to the north, at this time the drawbridge of the northern city wall was also lowered, and when this team rushed to the moat, the drawbridge was placed on the moat, and then the city gate opened, and the cavalry rushed in instantly.

Later, when the Tang cavalry wanted to rush in, the dense rain of arrows on the head of the city isolated them all outside the moat.

All this rabbit ups and downs, that is, in less than forty minutes, the whole action is smooth and beautiful.

When the drawbridge of the north city wall was put away again, the Tang army had begun to rescue the firearms battalion soldiers who were still in the fire, the scene was full of flames, black smoke was billowing out, and from time to time there were people covered in fire who rushed out of the fire and wanted to run to the moat, but they all fell halfway down the road, and the Tang army present asked about the aroma of cooked meat and the smell of burnt paste.

Li Shimin witnessed all this the whole process, his body kept shaking, his face was blue and his teeth were clenched, his hands were clenched tightly, his nails were deeply embedded in the flesh, but he didn't feel a little pain.

Twice in a row in the hands of Yang Wanchun deflated, originally thought that the Tang army captured the city of Anshi suffered heavy losses, the battalion Xiao casualties of more than 30,000, today the siege of the city is also a lot of casualties, the most important thing is that more than 2,000 firearms battalion soldiers were all killed, and the battle losses of the Goguryeo people are minimal, it can be said that this is a rare defeat of the Tang army in the past ten years.

The gunpowder could not open the city gate, and it was attacked by the Goguryeo cavalry, and the morale of the Tang army fell to the bottom. Li Shimin almost spit out word by word from his mouth: "Mingjin withdraws the troops!" ”

At the same time as the order was given, the soldiers of the Tang Army had already begun to collect the corpses under the city wall and carried them back to the camp in silence.

Looking at the corpse carrying over in front of him, Li Shimin only felt that his heart was like a knife: "Today I swear that as long as I break through Anshi City, the whole city will not be left with chickens and dogs, and Yang Wanchun's family and the nine clans will be late!" Li Shimin gritted his teeth and said fiercely.
