Cao Bianjiao's capture of Dezhou can be said to be a long-term plan, all the military supplies of the army are quite well prepared, this time responsible for the two Cao Bianjiao's favorite generals, Li Dingguo led 30,000 horse infantry to attack the southwest of Texas, Li Chengdong led 20,000 troops and horses to attack the northeast, Cao Bianjiao personally led the army to attack from the south, the north gate is the canal, the Qing army is not afraid of drowning, Cao Bianjiao does not mind driving them into the canal.

On the southwest city wall, Zu Dashou looked at everything in front of him silently, and he was also stunned in his heart, and only after a long time did he turn his head and say to Chang Jingong, the deputy general next to him: "No matter what it is, the current situation has not given us much chance, your method is worth trying, the soldiers in our hands are not enough to attack and defend, take the initiative to attack, or reverse the situation!" ”

"General, don't take any chances, let the last general go!" Chang Jingong also stood up and said: "Regardless of success or failure, I'll test it first, if I can break up the enemy camp, it's not too late for the general to take the men and horses to kill it." ”

Zu Dashou thought about it for the first time, and nodded and said, "Then you should be more careful!" ”

Chang Jingong was full of confidence, hurriedly ordered the army to prepare to go, the suspension bridge on the moat had been lowered, Chang Jingong took three thousand men and horses smoothly into the city gate, and rushed directly to the Ming army camp not far away, he led the Guanning iron cavalry.

The real Guanning Iron Cavalry is really a family-oriented army headed by Zu Dashou and with Jia Ding as the main combat strength. Due to the Battle of Daling River and the Battle of Songjin, most of the Zu family surrendered to the Qing Dynasty, and this army was also used by the Qing court and became an important part of the Eight Banners of the Han Dynasty. The Guanning Iron Cavalry in the hands of Wu Sangui was when Zu Dashou surrendered to Huang Taiji in the Battle of Songjin, Wu Sangui became the representative of the ancestral family in the Liao army of the Ming Dynasty, and incorporated thousands of families of the ancestral family to rebuild, and there are still some gaps with the old Guanning Iron Cavalry, and the men and horses in the hands of Zu Dashou are more fierce.

When Chang Jingong rushed less than a hundred steps in front of the Ming army, there were several shallow trenches in front of them, but this was nothing to the Guanning Iron Cavalry, they could rush up with a jump, but soon they knew how stupid they were.

"Let go of the ......" Li Dingguo watched the Guanning army getting closer and closer, and also issued a military order, and the thousand strong archers behind him released the arrows in their hands one after another, and they were rockets, and the rockets were fired into the Guanning army, and suddenly something unexpected happened, and a wall of fire suddenly rose in the originally shallow trench, and cut off the Guanning iron cavalry that rushed over from it.

The trench has already been done hand and foot, Cao Bianjiao has been filled with oil, and it is not ordinary oil, but oil, oil has been discovered very early, Shen Kuo of the Song Dynasty read in the book "Gaonu County has water, combustible", he felt very strange, how can "water" burn? He decided to go on a field trip. During the expedition, Shen Kuo found a brown liquid, which the locals called "stone paint" and "stone grease", and used it to cook on fires, light lamps and keep warm. Shen Kuo figured out the nature and purpose of this liquid, and gave it a new name, called petroleum. And mobilize the people to promote the use of trees, so as to reduce the felling of trees. Cao Bianjiao also discovered an oil field in Puyang, mined some for research, and has not yet been popularized.

When the rocket fell, it ignited the oil in the trench at once, and suddenly a wall of fire, the flames soared into the sky, black smoke billowed out, and the Guan Ning army suddenly became a mess, no matter how Chang Jingong shouted, it was useless, three thousand men and horses were cut in two, and it was difficult to echo before and after, and the Guan Ning army that rushed forward became a lamb to be slaughtered.

Chang Jingong turned the horse's head and wanted to kill back and cut open the city gate, how could Li Dingguo let go of the opportunity at this time, don't want him to greet him, muskets, artillery, strong crossbows and arrows, and greeted the Guan Ning army in front of them, a projectile hit Chang Jingong's arm, the projectile went deep into the bones, and his hand holding the knife was also difficult to use, and then it was shot into a hornet's nest by random arrows.

Guan Ningjun roared and screamed, the spearmen of the Ming army were already approaching, the distance between the two sides was getting closer and closer, and the tip of the spear was raised high, which was particularly terrifying. There were musketeers behind them to cover them, and the trigger was sounded from a distance of dozens of paces, and the smoke of gunpowder rose, and the cavalry of the Guanning Army fell off their horses one after another as if they had been electrocuted, and died on the spot. The Ming army didn't seem to be enjoying it, after the musket stopped shooting, he immediately changed his spearman and stepped forward, and there was a burst of stabbing at the people on the horse, many people splashed with clumps of blood on their chests, and the two layers of armor and three layers of armor also became vulnerable in the face of the sharp tip of the spear.

The Franco artillery behind the formation, the shells fired were more ferocious than one another, all of them crossed the wall of fire, bombarded the Guanning army behind, whether it hit people or horses, or fell to the ground, the shells would give the Guanning army a fatal blow, * fell into the Guanning army's formation, tearing out blood holes in their bodies, there was little hope of survival, they were beaten by themselves, not dead but also seriously injured, full of shrapnel, bullet holes, they couldn't die, and they were even more miserable.

Thirty or forty shells came head-on, the cavalry of the Guanning army was densely packed, although there were several horse positions separated from the front and back, left and right, but after the people in front of them were blocked by muskets, the people behind hurriedly strangled the reins, but the people at the back did not know, after all, the Guanning iron cavalry relied on the impact to tear the opening, so the speed at the beginning was very fast, this is not to say that you can stop if you stop, you can only adjust the direction to avoid colliding together, the key is that the subsequent attack of the Ming army completely disrupted their position, Crowded together.

Under several rounds of artillery attacks by the Ming army, the Guanning army paid terrible casualties, with 100 people killed on the spot and hundreds more wounded.

Zu Da Shoucai looked at all this above the city pass, and constantly ordered Ming Jin to withdraw his troops, but now it is not that they can retreat if they want to, Li Dingguo is well versed in the art of artillery attack under the guidance of Cao Bianjiao, and it is easy to deal with it if it is in echelon attack, intermittent bombardment, and the chaos of the formation is the first, killing the enemy is an additional role, as long as the formation is messy, it will be easy to deal with. Zu Dashou could only stare dryly, no way, he couldn't fight back, there were not many artillery on the city, their baggage had already been lost in Jinan, how many small cities in Texas could be, as soon as the war started, it was almost destroyed by Li Dingguo, he could only watch this scene.

Li Dingguo also looked proud, looking at the change of the situation on the field, since he was facing Zu Dashou, he naturally knew that he had a Guanning iron cavalry in his hand, and they ran fast in Jinan, but this time he naturally couldn't let them go, so he showed a smug expression on his face, no matter how powerful the cavalry was, it couldn't be the opponent of muskets and artillery, the muskets and artillery of the Ming army were all excellent versions, far stronger than the firearms of the Qing army!

"Kill...... Kill all these fake tartars! Under Li Dingguo's order, more crossbowmen and spearmen stepped forward to completely eliminate these Ming rebels wearing the uniforms of the Eight Banners of the Qing Army.

The three thousand Guan Ning army who rushed out of the city, when they went back, there were less than five hundred people left, most of them were wounded, and the rest of them all died tragically outside the city, and were brutally killed by the Ming army, Zu Dashou was not the first time to suffer a loss, at this moment he rushed to the slightest fear of this young general with a smile on his face outside the city, the other party was only twenty-five or six years old, but he used old soldiers, his eight thousand men and horses, more than 5,000 people have died in the hands of this young man, his deputy generals four, eight generals, all follow his old subordinates, also died tragically here, which made his heart like a knife.
