When Le Quan'an arrived outside Chengdu with the first forty warships, the Mongolian army defending the city only felt that the shape of these ships was quite strange, but they did not feel that there was much of a problem.

After all, although the Mongolian army and navy all came from the surrendered Song army, the Song army itself had many factions, and the shape of the ships was also different.

At a glance, a dense array of boats lined up on the wide water near the pier is quite impressive

The grand scene of "Gate Anchor Soochow Wanli Ship". The Mongolian guards guarding the wharf did not suspect that the Lequan'an fleet was flying the Mongolian flag, but said that these ships coming from the south were also grain ships, so they waved their flags to signal them to dock at the side.

The strange ships ignored the flags, and continued to move on, until they were half a mile away from the dock before coming to a halt in a long line of snakes.

The general of the Mongolian army in charge of guarding the dock was called Shi Mo Zhizhi, a Khitan. At this moment, he was standing on the city wall overlooking the docks below the city.

As one of the few generals in the Mongolian army who was proficient in water warfare, Shi Moji knew the importance of keeping the ships in formation and the rivers clear.

Although the Jinjiang is very wide in the wharf section, because of the large number of grain ships berthed, if the ships are allowed to park in a disorderly manner, it will inevitably cause chaos and even collision and sink, and these new ships do not listen to the flag and park indiscriminately, which makes him extremely annoyed.

He immediately sent men to punish these unruly ships as an example. Before the guards had reached the dock, Shi Mo noticed that something was wrong.

The new ships were now all facing the city walls and docks, and opened the windows on the side of the ship, each window protruding a hollow black tube, which reminded him of the legendary artillery, which the Mongol ships did not have, let alone artillery.

To say that this stone wiper was extremely war-sensitive, and at this moment he had judged that these incoming ships were friend or foe, and immediately ordered the trebuchet and bed crossbow to be fired.

At the same time as he gave the order, the Thunderbolt warships had already opened fire, and after a series of loud noises, the walls near the pier were covered in smoke, and the trebuchets and ballistas on the walls were destroyed.

Shi Mo was only swept to the ground by the air wave of the explosion, and two of his own soldiers were also injured by the explosion. It wasn't because of his luck or because the Thunderbolt artillery wasn't accurate enough, it was because the artillery wasn't aimed at him.

The attack on Ouyang Xuan in Chengdu was mainly from a political level, and the goal was to exert political pressure on the Mongol army in Chengdu to attack the Thunderbolt army's fortified fort.

There were many factions within the Mongols, and as a non-Mongol, Liu Heima was ranked among the 10,000 households, and many people in the Mongol army were quite unconvinced, such as the Mongol nobles who were stationed in Chengdu at the same time, such as the Mongol nobles Huoli and Baiyan Badulu, who were stationed in Chengdu at the same time.

These two have always been quite dissatisfied with Liu Heima's opposition to attacking the Thunderbolt army. If the Thunderbolt army hides in the mountains and does not surrender, if Chengdu is attacked, the core of the Mongol army's rule in western Sichuan, then Liu Heima must respond strongly.

does not fight back against this kind of behavior of riding face, not to mention that Liu Heima said that he was not convinced by the arrogant generals of the Mongolian army, and even the highest commander of the Mongolian army in Sichuan, Niu Ling, could not suppress it.

Although Ouyang Xuan did not give Huang Dagen a military target, he only asked him to bombard Chengdu City, as for the effect of the shelling, it was secondary, but Huang Dagen was obviously not satisfied with running away.

The task he assigned to Le Quan'an, who was the vanguard, was to destroy the naval wharf and kill and injure the Mongolian army personnel and city defense facilities as much as possible.

There are now only ten heavy artillery ships and twenty light artillery ships in the naval camp, except for the ten light gunboats that remained in Xinjin City and pinned down the Mongolian army in Pengshan City, the remaining ten heavy artillery ships and ten light artillery ships are shelling the city wall at the moment.

Although Ouyang Xuan asked for priority in the production of warship artillery, due to the limitation of production capacity, Li San'er, the manager of the industrial company, tried his best to produce only thirty warships of artillery.

Thirty may not seem like much, but judging by the heavy artillery ships equipped with four heavy mother and child guns, and the light artillery ships equipped with eight small mother and child guns, a total of 200 guns were needed.

These cannons are enough to equip thirty companies of the field battalion, not to mention the manufacturing cost, the amount of iron used alone is also an astonishing number, fortunately, the Perak army has a lot of iron ore to ensure the demand, no wonder Cao Ergou complained everywhere that the navy army is a gold-swallowing beast, squeezing out the artillery equipment of the field battalion.

In order to ensure the safety of the gunboats, the naval battalion equipped them with escort boats, and at the same time demanded to open fire outside the enemy's long-range fire.

But Le Quanan saw that the Mongolian army did not see through its disguise, so he ordered to shoot at close range. He ventured to do so, not only to improve the accuracy of the shelling and save ammunition, but more importantly, he found a large number of ships neatly docked around the docks—all of them grain ships, and several warehouses on the shore nearby.

He wanted to send people to occupy the dock and seize the grain, so of course the closer the ship was to the dock, the better. Twenty gunboats destroyed the long-range weapons deployed by the Mongols at the head of the wall in the first round of fire, and did not receive a single counterattack.

In fact, the gunboats were less than a mile from the city walls, and although trebuchets could not reach this distance, only heavy bed crossbows could shoot them.

Many of Pu Ze's elites surrendered to the Mongol army with bed crossbows, which could send arrows like spears and as thick as children's arms, which were a great threat to ships and artillery, but also had great lethality to personnel, even if they were grazed by this arrow, they were either killed or injured.

After suppressing the Mongol army, Le Quanan ordered people to seize the ship. When Huang Dagen arrived with the follow-up ships, Le Quanan had already taken the grain ship.

Due to the sharp rise of the river in the past few days, many places near the shore of the wharf have been submerged, and the city has been short of warehouses due to the long-term war, and the grain transported from various states and counties must also be transferred immediately for the use of the new army fighting in eastern Sichuan, so Liu Heima ordered the grain to remain on the boat, and ordered Shi Mo to guard it strictly.

It's just that most of the Mongolian sailors stayed on the shore, and there were less than 100 people on the grain carriers, and most of these people had already fled in fear by the huge power of the gunboats, and the rest couldn't stop the attack of the twenty escort ships under Le Quan'an.

It's just that the grain ship is easy to take, but it is not easy to transport the materials in the warehouse on the shore, and the reason is that there are too few people with Le Quan'an.

Not only did they have to bombard the Mongol cavalry and the new annexed army that rushed to the shore after hearing the news, but also prevent the water ghosts under Shi Mo from attacking the gunboats, so they could only send more than 100 people ashore, and it was too difficult to fight the new annexed army that rushed to the shore while carrying things in the warehouse.

The Mongol navy was robbed of the ships and basically scrapped, so they had to constantly send people to dive into the water and try to scuttle the ships, but they suffered heavy casualties under grenades and spears.

In addition to the naval army, the Mongol army also had 1,000 cavalry and 2,000 new annexes stationed in the city, and the first to rush to the docks to reinforce it was the cavalry under the secret fire.

These cavalrymen, with their superb horsemanship, drove their horses through the mud to the gunboats, only to find that they could do nothing when they reached the shore.

The range of the Mongol cavalry bow was obviously inferior to that of the bed crossbow, and it could not shoot at all the boats in the center of the river, but instead suffered a large number of casualties under intensive artillery fire.

The Thunderbolt soldiers in the warehouse retreated to the ship when they saw the Mongol cavalry rushing towards them, and the cavalry retreated and went back to carry things.

After repeating this several times, the Mongol cavalry lost dozens of men, and had to retreat far beyond the range of the artillery to wait for the arrival of the new annexed army.

They just can't afford to take that kind of casualties.
