When the ships of the Jinghu Navy carried these barbarian strong troops down the Yangtze River, they received the wax pill book sent by Zheng Yunming to copy the path, and agreed to take the white fog from the sky as the signal, wait for the white fog to dissipate slightly, or there is heavy rain or sunny days, and immediately take the boat east to attack the largest pontoon bridge of the Mongolian army on the mouth of the three rivers.

In fact, there are three pontoon bridges connecting the north and south on the Yangtze River, the pontoon bridge in Huhuangzhou and the pontoon bridge at the mouth of the Sanjiang River are the two most critical, and a pontoon bridge near the Qingshan area in the upper reaches is far away and the shape is smaller, and it can only pass some auxiliary troops and food supplies. Most of the tasks of north-south traffic were entrusted to the pontoon bridge at the mouth of the three rivers. This huge pontoon bridge also lives up to Meng Ge's trust, and the pontoon bridge that can allow 100,000 people to cross the Yangtze River in just one day and one night is not unprecedented, but it must be unprecedented. In order to defend it, the Mongolian army pulled up three thick iron locks on the river, this kind of iron cable across the river tactics is the old trick of the Central Plains naval army, used to limit the navigation of the enemy's warships on the water, each iron lock is tied to a warship every other section, its name is the mixed river dragon, there is a water row artillery fortress after the iron cable, over the years the water row artillery fortress has become the most distinctive part of the Mongolian naval army, the water battle of the Mongolian army's southern expedition is more unfavorable, once the defeat will return to the water village, relying on the fierce artillery fire of the water row artillery fortress to block the enemy's pursuers, It can be said that the water row artillery fortification became the most vital part of the Mongolian naval army, and even the Song Dynasty recognized the effectiveness of this water fortification and imitated it.

There are more than 20 artillery forts of different sizes guarding the left and right of the Sanjiangkou pontoon bridge, among which the largest artillery fort is stacked three times, and the middle fort is assumed to have a terrifying 6,000 jin super cannon, and the top fort is also equipped with a cannon crossbow, which is earth-shattering under one shot, and the cannonball can fly into the center of the river, although its range cannot catch up with the Shenwu cannon, but it is also very amazing.

Behind the water row, there is a blockade with fishing boats, on which wooden planks are laid, huge wooden shields are erected, and soldiers patrol back and forth on them, and if they find an enemy boat approaching, they can immediately board the fishing boats to defend it.

The river swelled in the heavy rain, ?

?? The swinging river made the speed of the Song warships rushing to the pontoon bridge greatly accelerated, and the Mongolian naval warships in front of the three lines of defense could not stand still under the impact of the turbulent river, and were carried down by the river water, and crashed into the first mixed river dragon one after another.

The Song army sent small boats carrying heavy axemen with long-handled steel axes to lean forward and split the iron ropes with giant axes. Although this must have hundreds of strong men with great strength, is there still a lack of strong men in the army? Under the dance of hundreds of battle axes, the three mixed river dragons all turned into powder.

The rain poured down, and there was not even the slightest sign of abating, and even the Yangtze River, which was as wide as a stretch, swelled sharply, and the faster the speed of the river, the more inconvenient it was for the two sides to fight. It was even more disadvantageous compared to the Mongol naval forces located downstream. Especially those bulky and large warships, which could barely avoid the small boats that rushed from the upper reaches of the river. The soldiers in the boats carried canisters filled with oil oil, which had a special recipe to burn continuously in the rain and not extinguish it unless it was splashed with sand or vinegar.

The Mongolian officers and soldiers stationed on the fort were surprised to find that their commander Dongping Wanhu Shi Tianze personally appeared on the largest water row fort wrapped in gauze, and the color under his heavy iron helmet was extremely ugly, and he shouted loudly in the wind and rain: "Today's battle is just death!" Stay in your position for me, and behead anyone who dares to leave the position! ”

At this time, someone exclaimed: "It's Jiao Jin, it's Jiao Jin's banner!" ”

Rushing to the front of a large sea bird boat, standing on it full of soldiers draped in clothes, while advancing from the side of the continuous spray of fire, the Mongolian warships on both sides of it one after another burst into flames, as if there is no invincible momentum, there is a word on the bow of the ship, although the heavy rain is pouring, Shi Tianze can see at a glance that this is the flag of his old rival for many years. He spat at the mouth, and ran up to the top of the fort in three steps and two steps, the top of the fort was a newly regulated Shenfeng pulley crossbow, wound with a roulette wheel, and the iron gun was the arrow, and the range could reach a thousand steps under one shot. Several crossbowmen in the canopy were nervously operating, Shi Tianze stepped forward and lifted the aim, and shouted: "Give me a full string, just use this arrow to kill Jiao Jin and crush the Song people's offensive!" ”

The crossbowmen turned the winch desperately, the bowstring squeaked and opened, almost to the verge of breaking, a crossbowman placed a black iron gun on the arrow slot, Shi Tianze carefully looked at the approximate distance of the ship, he also knew that although Jiao Jin was silent, he was loyal and upright, and would never use a puppet to make a show, and the military general sitting in the bow of the ship must be Jiao Jin himself. The two have fought several times, Shi Tianze has never had such a sure chance to snipe his opponent, even the legendary heads-up three years ago is not as sure as it is today, if you say why you are so confident, maybe it is the fighting spirit of the beast that is forced into a corner and burns.

Shi Tianze carefully moved the direction of the pulley crossbow, he was seizing the best opportunity to deliver a fatal blow, such a chance is only once, once he misses, there will be no chance to turn back. He cautiously observed Jiaojin's ship, estimating the distance between the ship and the fort, when suddenly a nearby Song army vehicle and ship fired a cannonball, smashing a corner of the fort, and the flying wood chips burst the brains of a crossbowman, and the corpse fell to the ground on the spot.

"What are you panicking about!" Shi Tianze shouted loudly: "Strong men are rampant on the battlefield, are you still afraid of death!" He turned around and glanced at Wangshan, turned it upside down with the heavy axe in his hand, and slammed the back of the heavy axe on the tooth machine.

On the huge seabird boat, Jiao Jin's guards were shocked, and they found an iron spear arrow breaking through the air from the left side, piercing Jiao Jin's chest and abdomen with lightning speed.

Jiao Dutong's body was half red with blood, and his face was pale, but he forcibly endured the severe pain, and sat firmly on the chair, and several personal soldiers hurriedly stepped forward to carry him down, but he was stopped by him with trembling hands.

"At this time of life and death, leave me alone, order the whole army, and continue to march!"

At this time, the Song army, the navy and the infantry soldiers, did not know the fact that the main general had suffered heavy losses, and took advantage of the wind and rain to desperately attack the artillery forts one after another in front of them, the fierce fire of the Dongting gunboats destroyed the beams of the wooden castle in the heavy rain, and the small boats were full of paper armor soldiers rushed forward and engaged in hand-to-hand combat with the enemy on the wooden platoon. The sound of shouting and fighting shook the sky, and even the heavy rain could not hide such a magnificent sound.

"That's it! I am now a minister of a great power, how can I abandon the Great Khan and flee first! Soldiers, don't retreat, follow me! He tore the gauze off his body, revealing his chest still with terrifying scars, and with a big axe in his hand, he rushed into the Song army formation on the wooden platoon.

The power of the 6,000-pound heavy artillery is naturally good, but the low casting process of the Mongols makes it difficult to guarantee the accuracy of the super heavy artillery, and the fired shells are difficult to hit the warships approaching at high speed, although the crossbows and the rest of the small and medium-sized artillery also shoot fiercely, but obviously can not suppress the fierce firepower of the Song army's ship guns, and the melee on the wooden platoon also shows that the Mongolian army is indeed no longer as tenacious and good at fighting as before, the Song army only used a few forced landings to destroy the Mongolian army's defense near the wooden platoon artillery base, and the Mongolian army has landed on the shore and rode war horses and scattered in all directions, Most of the water platoon artillery forts fell into the hands of the Song army.

After the Song army occupied the fort, they immediately turned the muzzle of the gun and used the artillery and crossbows on the fort to shell the pontoon bridge and the last line of defense to defend the pontoon bridge. To be fair, the last line of defense of the Mongolian soldiers showed much more heroism than the first two lines of defense, these Mongolian conscription of Goryeo sailors, originally were the elite of Goryeo's long-term training, one of the results of Möngke's eastern expedition to Goryeo, was to persuade the surrendered Goryeo to send 20,000 troops south with the army to conquer the Song Dynasty, these Goryeo sailors under the command of Marshal Wang Jing, fought very tenacious, and even sank into the river with the Song army that jumped up, Wang Jing was also hit by several bullets and still struggled, killing dozens of Song soldiers, But after all, they had not experienced a truly powerful firearm attack, and the lead bullets that cut their heads and faces were like sharp scythes, and pieces of grass cut the lives of Goryeo soldiers, and soon shattered the last line of defense of the pontoon bridge.

The Han infantry standing on the pontoon bridge in formation was already unstable at this time, the Song army broke three formations in a row, and the fighting spirit became higher and higher, and as the war continued, a large number of fresh troops came up from the rear on flat-bottomed boats, and their offensive showed no signs of exhaustion. What's more deadly is that at this time, the river rises, the giant ships of the Song army collide head-on, the archers and firecrackers are hiding under the deck and shooting condescendingly, the Mongolian soldiers on the pontoon bridge have no power to fight back, and the killing of the black barbarians and white barbarians is extremely ferocious, every time they kill an enemy, they cut off his head on the spot and put it into the leather bag, so the leather bag on the waist of each barbarian soldier is quickly full. These brutal barbarians howled and slaughtered in the wind and rain, and even though they were battle-hardened Mongol Han troops, they still felt a chill.

On the other hand, the Song army used giant axes and long saws to start destroying the pontoon bridge by various methods, and the cavalry brigade gathered from the shore in panic struggled to release arrows on the bridge, but it was blocked by the dense infantry wall and could not launch the most powerful cavalry charge, in fact, even if their charge could reach the bridge, But the bridge is now full of fighting and scuffling crowds, the slightest carelessness of the cavalry will be knocked off the horse, not to mention that the Song army's gunboats are constantly shooting towards the shore, the horse team is crowded on both sides of the bridge, but it is difficult to give real support to the friendly troops on the pontoon bridge.
