The siege ladder used by the Liao army is made by special craftsmen, it is very strong and sturdy, there are two huge iron hooks above the head, the city wall is firmly hooked, it is difficult to cut it, the Han people of the Liao army also inherited the courage of the Liao army, they climbed to the head of the city desperately, but they were greeted by the rolling wood and stones on the head of the city, a piece of thirty or forty pounds of stones and three feet long thick wood fell like hail, and the soldiers on the siege ladder screamed and fell down from the city.

Dozens of siege ladders broke out into similar fierce battles, with Song soldiers hiding on Mamian City and firing arrows at the backs of the Liao soldiers besieging the city on either side.

For a time, the arrows above and below the city were like a torrential rain, and the dense arrows were overwhelming.

'Woo-' The horn of the Liao army sounded, and another 5,000 infantry came up, bringing the besieging Liao army to 15,000 people, deducting all kinds of casualties, and there were less than 13,000 people.

The besieging Liao army gradually concentrated in the southwest and northwest corners, where the formation could not be placed, whether it was trebuchets or bows and crossbows, they were much rarer than elsewhere, and the Liao army found this weakness and gathered to the two corners.

More than 30 siege planes are concentrated in these two areas, boom! Rumble! Two anti-pull siege ladders rushed up, resisted the city wall, there were dozens of people on both sides of each side to pull the long rope together, a long ladder full of soldiers was erected, directly to the city head, the biggest advantage of this anti-pull siege ladder is to subtract the climbing process, one step in place appeared at the head of the city.

The disadvantage is that it is cumbersome, and it requires a borrowing point, which is generally after resisting the city wall, dozens of people pull back together.

This kind of anti-pull siege ladder also existed in the Song Dynasty, but the Song Dynasty was a large siege weapon, which was installed with eight pulleys, pulled with iron chains, and could send more than 40 people in three rows to the city at the same time, which was much more advanced and powerful than the siege ladder of the Liao State.

The soldiers of the Song army had already prepared, and when this kind of anti-pull siege ladder just approached the city wall, dozens of spears poked together, and the top three soldiers were immediately stabbed to death, screaming and falling down the city.

Immediately afterwards, more than a dozen clay pots filled with fire oil smashed down, the clay pots shattered, the fire oil was poured all over the siege ladder and the soldiers, several torches were thrown down, the siege ladder immediately burned, and more than 20 soldiers on the ladder were also ignited, and they all jumped into the moat screaming.

At this time, nearly 10,000 soldiers had gathered in the southwest and northwest corners, and Cao Wenjing saw that the time was ripe, so he ordered: "Launch iron fire mines to the southwest and northwest corners." ”

More than 30 ignited iron fire mines were thrown out of the city one after another by small trebuchets, which had a projection distance of about 100 paces, which happened to be the most dense place for the siege soldiers.

"Lie on your back!" Someone in the city shouted.

The soldiers of the Song army at the head of the city covered their ears and squatted down, only to hear a series of earth-shattering explosions, the fire burst out, black smoke rose into the air, powerful shock waves and iron nails shot in all directions, flesh and blood flew sideways, limbs shot everywhere, the terrible screams were covered by the explosion, hundreds of cavalry hundreds of steps away were also affected, the war horses fell to the ground, the cavalry fell, the city wall also shook, the soldiers on the siege ladder all fell, and the entire outside of the city was shrouded in pungent gunsmoke.

Yelu Kunping, the commander of the Liao army, and the cavalry who were watching the battle from a distance were stunned, of course they knew that this was the firearm of the Song army, but they had never seen such a powerful firearm.

Yelu Kunping did not hesitate to order: "Mingjin retreats!" ”

'When! While! While! ’

The bell rang in a hurry, and the Liao army withdrew like a tide, but what made Yelu Kunping even more frightened was that only more than 6,000 people withdrew, and more than 30 iron fire thunders of the Song army killed and injured more than 4,000 people.

In fact, there were only more than 1,000 soldiers who were really killed, and most of the soldiers were shocked to death, this was the first time that the iron fire thunder was used on the battlefield of Song Liao, the Liao soldiers had no experience, if they could lie on the ground in time and avoid the shock wave shock, the death toll would probably be reduced by half.

Most of the soldiers killed this time were Bohai soldiers, who stood behind, and the iron fire and thunder happened to fall into their soldiers, killing nearly 3,000 people.

Seeing that the morale was low and it was not suitable for him to fight again, Yelu Kunping immediately shouted: "The whole army withdraws to the camp!" ”

With the sound of low drums, the Liao soldiers slowly retreated, withdrawing from the large camp ten miles away.

The Song army at the head of the city suddenly burst into cheers.

Wang Xuan was a little excited: "With iron fire and thunder guarding the city, we will not be afraid of the Liao army!" ”

Cao Wenjing said lightly: "Although the Iron Fire Thunder is a sharp weapon for defending the city, if we rely on him, once the Liao Army finds a way to defend it, the power of the Iron Fire Thunder will not be as great as it is today." ”

"How to defend against iron fire and thunder, does the general know?"

Cao Wenjing nodded, "Fan Xianggong told everyone that if you can crawl on the ground before the explosion of the iron fire and thunder, and cover your body with a shield in time, the killing effect will be reduced by more than half." ”

Wang Xuan sighed, "I hope the Liao army won't find a way to defend so quickly!" ”

Cao Wenjing smiled, he saw that the enemy army was far away, so he turned around and ordered: "Go out of the city to clean up the battlefield, the wounded Han soldiers of the Liao army can be treated, and the other Liao soldiers will be killed!" ”

The gates opened, the drawbridge slowly fell, and two thousand soldiers rushed out, cleaning up useful booty, treating the wounded, burning and burying the bodies.

In the first siege battle, the Liao army failed at the cost of 8,000 casualties, and a carrier pigeon rose from the top of the city and flew towards Hejian City.

.........

At night, Yelu Kunping was a little restless in the big tent, as the privy deputy envoy of the Southern Yuan, he had already understood that today's Song army's weapon was the legendary iron-shelled fire thunder, and at the same time he also witnessed the powerful power of the iron-shell fire thunder, an explosion blew up more than 4,000 Liao troops to ashes, and only 12,000 people were left from the 20,000 infantry, what should I do next?

Continue the siege, or withdraw the troops? Or abandon Baosai City and go directly to Hejian Province to join the Eastern Route Army?

Continuing to attack the city, Yelu Kunping no longer has the courage, he doesn't know how many iron and fire thunders there are in the city, if there are a hundred more, I am afraid that the infantry will be wiped out, this huge risk he cannot afford.

In fact, Yelu Kunping's original intention was to retreat, but retreating would inevitably be severely punished by Yelu Hongji, the Son of Heaven, but if he didn't retreat and went around the city to Hejian Mansion, then he would have to give up all his baggage, he couldn't afford to lose this face, and the boss wouldn't allow it.

Yelu Kunping paced a few laps with his hands, but he thought of a way, since there is no road in the wilderness, then ram a passage out, that is, more than ten miles, go around the city, at most ten days and half a month can be completed, so that the baggage can pass.

........

Early the next morning, 30,000 cavalry left the camp and headed northeast, almost all of the wheat fields in the north of Baosai County, but they had been empty for a year, overgrown with weeds, and the ice and snow thawed in spring, the wilderness was very muddy.

Although the idea is good, but the implementation is not so easy, first of all, there is no tool to ram the ground, the ramming is generally made of wood, five or six people use a rope to hold the wood and smash it downward, and the Song army is strong and clear, there is not a single tree within a radius of dozens of miles, dismantle the siege weapons to ram the ground, one is not so much thick wood, and the other is what to do after the siege weapons are demolished? The Eastern Route Army is still waiting for their siege weapons to come to the rescue!

Thinking of this, Yelu Kunping immediately divided his troops into two roads, on the one hand, he ordered 30,000 cavalry to repeatedly run and trample in the field, on the other hand, he ordered 3,000 soldiers to rush to Bailongling, which was more than ten miles away to the south to quarry, which was a stone mountain, without trees, only large and small stones.

At the head of Dongcheng, Cao Wenjing watched from afar the 30,000 cavalry rushing towards the official road more than ten miles away, he sneered, turned around and ordered: "Light the beacon fire!" ”

The beacon tower on the head of the city was lit, and it was immediately discovered by the soldiers of the Liao army, and someone reported Yelu Kunping, and Yelu Kunping was also stunned, what does it mean that the Song army lit the beacon fire?

Yelu Kunping suddenly had a very uneasy feeling in his heart, and at this moment, he suddenly felt that the earth was trembling, and he suddenly thought of something, and when he turned around, he saw a black line in the west coming towards his camp.

"Not good!"

Yelu Kunping shouted, and immediately shouted: "Quickly order the cavalry to come back!" ”

His 30,000 cavalry were walking thirty miles to the east, how could they come back so quickly, and the infantry was tidying up the road more than ten miles away, and the defenders in the barracks were less than a thousand people, and the Song cavalry in ambush on the periphery seized this extremely short opportunity.

10,000 Song cavalry lay in ambush ten miles away, and their task was to see through the seams and look for every opportunity to destroy the enemy's baggage, grain, grass and other logistical materials.

Ten miles is also the boundary of the Liao soldiers' outposts, and hundreds of outposts form an artificial defense line ten miles away, and once an abnormality occurs, they will immediately send a message to the camp.

The beacon smoke of Baosai City sent a signal, 10,000 Song cavalry suddenly killed, straight to the Liao army camp, in the blink of an eye they rushed into the camp, the 1,000 soldiers guarding the camp were so frightened that they scattered and ran, hundreds of craftsmen could not escape, they were surrounded by the Song army cavalry, and they were killed.

The Song army quickly set fire to the tents, baggage, grain and grass, and then rushed south like another gust of wind to encircle and annihilate the 3,000 Liao soldiers who were quarrying.
