The flood has not completely subsided, and a vigorous production campaign has begun in the territory of the Perak Army - planting seedlings. At this time, the soil has been soaked very soft, and there is a thin layer of silt in many places, which is very conducive to planting rice seedlings. Ouyang Xuan, who attaches great importance to grain production on weekdays, uncharacteristically did not go to the fields to work in person, and did not even go to the fields to inspect the situation. At this time, he was on the ship to Xinjin City. In the cabin, he read the battle plan of the General Staff Headquarters while facing the map, and among the few people standing beside him were Xia Dagen, a staff officer who took the lead in drawing up this combat operation, and Huang Dagen, a chief of staff who had just returned from Maozhou.

Yu Xing's order was to contain the Mongol army with the Thunderbolt army, but the Thunderbolt army did not want to stop there. When Ouyang Xuan proposed to seize Pengshan and Meizhou at the joint military-political meeting, he was unanimously supported by the top brass of the Perak Army, and even Yu Zhu, who had always been calm, applauded. The people of western Sichuan have been suffering for a long time! The recovery of Pengshan and Meizhou, in addition to rescuing the people from fire and water, can also open up the water passage to the south to obtain a steady stream of funds and information. At present, the Perak Army is developing rapidly, and it is urgent to obtain strategic materials south and east of Jiading and even the former Dali State, and it is also necessary to find a broader and more stable sales market for industrial products.

According to the battle plan drawn up by the General Staff, the military operation troops to seize Pengshan City were divided into two routes. The first road is down the waterway, under the personal command of Ouyang Xuan, there are all the naval brigades, two infantry battalions of the field brigade, and the training battalion of the garrison brigade, with a strength of 3,000 people, which is also the main direction of attack. The plan of the staff was to destroy the city defense by gunboats, and then occupy the city by infantry, and the other way was a partial division from Changqiu Fort, and a special brigade commanded by Dong Hu to attack Pengshan from the flank, with a strength of 1,000 people, including three companies of cavalry, to be precise, called mounted infantry.

Because the flood water has not completely subsided, the road surface is extremely muddy and slippery, and there is still a lot of water in some places, and it is impossible to pass through heavy artillery at all, so the field brigade and the training battalion only brought light artillery to participate in the military operation, and the naval army was responsible for the firepower of attacking the fortification. The three battalions of the naval brigade now have 30 light artillery ships and 10 heavy artillery boats, which should be equipped with a total of 240 light guns and 40 heavy guns, but due to the insufficient production capacity of the arsenal's new naval guns, only 140 light guns and 30 heavy guns are equipped. However, according to the calculations of the General Staff, this firepower configuration was enough to suppress the Mongolian army. Besides, the infantry of the field brigade and training battalion also brought light artillery, as well as muskets and grenades, which was enough for the Mongolian troops in Pengshan City to drink a pot.

In order to prevent the Mongol army from taking the opportunity to sneak attack when the army moved south to Pengshan, the General Staff left the cavalry battalion of the field brigade in Chongqing Fucheng. However, the area occupied by the Mongol army was also full of mud that had been raised after the flood, and it was obviously extremely difficult to march and assemble at this time, and the rivers were still turbulent, and it was extremely difficult to cross the river. The only target that the Mongols could attack without crossing the river was Guan Kou Village. In order to prevent the Mongols from sneaking up on Guankou Village, Ouyang Xuan had personally taken a boat to inspect the village the day before yesterday, and asked Yu Zhu to transfer three more companies of basic militia to assist in the defense. At present, Shi Zhongshu is leading the people of Guan Kou Village to dig trenches, build walls, set up horses to resist horses, and lay a lot of mines.

Once everything was ready, the Perak fleet headed south. Set off in the morning, and at noon, I already saw Pengshan City from afar. The Mongolian army at the head of the city saw the mighty Thunderbolt army fleet, and naturally it was a mess. At this time, the water in Pengshan City is still up to the ankles, and there are rotten wood, rotten clothes and other debris floating in the low-lying places, and occasionally there are drowning rats and other small animals, which emit a foul smell in the summer heat. Before the flood, there were 1,000 new troops and 300 Mongol cavalry in the city, more than 20 artillery pieces on the wall, and more than 200 small warships. When the flood came, most of the Mongol cavalry fled to higher places, and the few cavalry who did not escape were also picked up by their companions after the water receded, because of the plague in the city. Because of this, the Mongols did not allow the new annexes to go with them to high places to avoid water, so as not to infect them together.

The great flood uplifted germs buried deep in the soil, which is also the cause of the frequent plagues in the aftermath of the disaster. The soldiers and civilians of Pengshan City, who were trapped on the city wall, were thirsty and thirsty, and they naturally fell ill after drinking the dirty muddy water, and they vomited and diarrhea one after another. At this time, the few people in the city were sick and hungry, and there were less than 500 people left. The soldiers of the new annex army only died less than 100 because they were all in the prime of life and had strong disease resistance, but most of them were tortured a lot, and many of them even staggered to walk, where could they fight with weapons? In the eyes of these new annexes defending the city, the Thunderbolt army came to attack at this time, which was "taking advantage of my illness and asking for my life"!

If you can't beat it, why don't you run away? That's because the Mongols simply didn't allow them to flee without a fight. The roads outside the city were muddy, and after not going far, the Mongol cavalry would catch up and exercise military law. A considerable part of the new annexed army in the city was a naval army, but because the water village was washed away by the flood, most of the boats anchored were gone, and a small number of boats could not cross the river smoothly under the pursuit of the Perak army. Despite their predicament, these new annexes refused to rest on their laurels. Although the reasons for the surrender of these traitors to the Mongol army are different, they all have in common that they are greedy for life, fear of death, and greedy for pleasure. In their view, although being a lackey of the Mongols was discriminated against, it was better to be able to get some leftovers, and if you were lucky, you could eat and drink spicy food, which was better than serving hard labor in the dark mines of the Perak army.

The new annexes in the city refused to surrender, partly because they fantasized that the Mongols would come to their aid. This Pengshan City is too important, to the north can enter Xinjin City, to the east it will be connected to Chengdu City, and to the south it can go down to the river through Meizhou and Jiading, even if the Mongolian army does not save them, it will not easily give up this strategic place. On the other hand, although there is a shortage of drinking water and diseases in the city, the city defense has not been damaged. With twenty well-preserved cannons on the city's head, there is still the strength to fight. These guns were already deployed on the city walls, and the ammunition was transferred to the city walls in time. In the eyes of the new annexes, the Thunderbolt army, including light artillery ships, came many times, and had to retreat under the fire of the city wall artillery. It only needs to hold out for a few days, and as soon as reinforcements arrive, the besieging Thunderbolt army will naturally retreat.

It's just that "the ideal is very plump, and the reality is very skinny". Seeing that the Thunderbolt warships were approaching, the new annexes on the city wall adjusted their guns and fired into the river, but the shells fell into the water one after another, splashing huge splashes, and did not hurt the Thunderbolt warships, because the bullet impact point was still half a mile away from the center of the river where the Thunderbolt warships were anchored. "Come and don't be rude", seeing the fire at the head of the city, the Thunderbolt warships also quickly adjusted their arrays. The ten largest gunboats slowly turned, facing the wall of Pengshan, and then the side window panels opened, revealing a row of black hole gun ports. Immediately afterward, the muzzles of the guns were filled with fire and smoke, and solid bullets flew towards the city with a loud screech.
