In recent years, with the full support of the Flying Tiger Army, Peng Yibin has become an important force in the north to resist the Jin Army and the Mongolian Army after a complete break with Li Quan, and has expanded to the north year after year, and the territory under his jurisdiction has become the largest force in the Northern Loyal and Righteous Army, and his command claims to have hundreds of thousands of heavy soldiers, and the force seems to be quite powerful.

But Peng Yibin is a rough man in the end, although he is loyal and righteous, brave and good at fighting, but he lacks the ability to manage local affairs, his main energy is focused on the military affairs of the strategy, and the economic development within the jurisdiction is very limited, his number of soldiers and horses seems to be a lot, but the real elite is not very many, and he has to be scattered in the states and counties within the jurisdiction to garrison, but also disperse his troops.

Previously, before Polu led the troops to the south, Liu Chengyi had written a letter in the name of the Flying Tiger Army to remind the Mongols that they might take action, and Li Quan was likely to switch to the Mongols, so Peng Yibin was careful, Peng Yibin attached great importance to this matter, and Chen soldiers in Shenzhou and Jizhou were more than 60,000 people, so that several generals under his command led the attack of the Mongolian army, and he himself was also in Jinan Mansion after the year to send troops to prepare, intending to cooperate with the Flying Tiger Army and the Song Army to completely kill Li Quan, and remove this scourge for Jingdong, However, Polu's dispatch of troops soon interrupted his plan, and Peng Yibin had to give up his southward attack on Li Quan, so he had to hurry to Jizhou, intending to lead his troops in Jizhou to stop the southward movement of the Mongol army.

It's a pity that Peng Yibin's quality of generals is still not elite enough, and when he arranged the defense of Jizhou, he made a major mistake, that is, he did not arrange a person in the middle of the dispatch, although there are a lot of troops, but they have not been uniformly deployed, Polu is familiar with the classic tactics of the Mongolian cavalry, that is, to advance quickly, without giving the enemy any chance to react, after Zhang Rong surrendered, it took only one day to lead the army into Jizhou, the Mongolian cavalry was divided into several branches, and attacked several defenders arranged by Peng Yibin.

These rebels are infantry troops, and Shenzhou and Jizhou are in the middle of the Hebei Plain, the low-lying plain area alluvial from the ancient Yellow River, the terrain is very flat, very suitable for the Mongolian cavalry high-speed deployment, although these Peng troops also insisted on resistance, but under the sharp offensive of the Mongolian iron cavalry, they were defeated and fled, Shenzhou only resisted for two days, it was conquered by the Mongolian army, most of the defenders were annihilated, Peng Yibin prepared 60,000 defenders fell apart like water rushing to the anthill in a few days, and nearly 30,000 people were slaughtered, Even Shenzhou City was slaughtered by the Mongol army, and the soldiers and civilians in the city were almost killed, and there were less than 10,000 soldiers who fled back to Jizhou City, and the defenders of Jizhou City were only more than 15,000 people.

At this time, Zhang Rong supported the 20,000 soldiers and horses to Polu, and at this time also arrived outside Jizhou City, helped the Mongolian army to besiege Jizhou City, and as the main force of the siege, launched a siege battle against Jizhou City.

Peng Yibin's righteous army has expanded rapidly over the years, but the quality of equipment is very poor, they do not have the foresight and wisdom of the Flying Tiger Army, and they have not established a unified weapons supply system, the source of weapons is mainly temporary patchwork or capture on the battlefield, and the other is to rely on the Flying Tiger Army to assist them with some armor, but it is far from enough to solve the problem of their equipment, even their military rations mainly rely on the Song Dynasty to transfer a part of them by sea through the jurisdiction of the Flying Tiger Army, and the Flying Tiger Army supports them part, They produced a part of it themselves, so that they could basically meet the demand, and the quality of their equipment was very different from that of the Mongol army that had been fighting for many years and had obtained the huge wealth of the Jin Kingdom, the Western Xia, and many defeaters in the Western Regions.

Peng Yibin, who had just arrived in Enzhou, was shocked when he heard the news, he had fought with the Mongolian army over the years, but he didn't expect Polu to be so powerful, there was no room for him to fight back, and he captured Shenzhou in a few days, and surrounded Jizhou, which completely disrupted his deployment, so that Peng Yibin had to immediately dispatch troops to strengthen Enzhou's defensive force, in case Jizhou was broken, the Mongolian army immediately waved its division to attack Enzhou, in that case, the hinterland of his Jinan Mansion was equivalent to being open under the Mongolian iron hoof.

However, Polu's good fortune also came to an end temporarily under the city of Jizhou, the Jizhou guard was Peng Yibin's fierce general Zhang Shi, this person is not only brave, but also quite wise, knowing that he will never be the opponent of the Mongolian army, after the Mongolian army conquered Shenzhou, he immediately collected the defeated and fled back to Jizhou in Jizhou, and moved all the people within dozens of miles outside the city into Jizhou City.

The northern residents have long known the ferocity of the Mongolian army, and know that as soon as the Mongolian army arrives here, most of them will become the ghosts of the Mongolian army.

After the Mongolian army arrived outside the city of Jizhou, it demanded that the city of Jizhou be opened and surrendered, but the soldiers and civilians in the city of Jizhou had already learned the news of the massacre in Shenzhou, and they were already full of grief and indignation, and the soldiers and civilians in the city were united in hatred of the enemy, and resolutely refused to surrender under the leadership of Zhang Shi, but mobilized all the people in the city, from the seventy-year-old old man to the teenager in his teens, all of whom were put into the preparation of strengthening the city defense and defending the city.

Originally, the population in Jizhou City was not too much, because Zhang Shi prepared in advance, gathered nearly 100,000 people into the city to help defend the city, plus more than 10,000 righteous troops in his hands, the number of men available in the city reached more than 40,000 people, which greatly enhanced the defense force of Jizhou City.

For Jizhou City's refusal to surrender, Polu immediately ordered to start attacking Jizhou City, the first batch of main force to attack the city was the rebel army under Zhang Rong's command, many of these people were dissatisfied with Zhang Rong's treacherous surrender to the Mongols, turned around and attacked Peng Yibin's territory with the Red Jacket Army, so the combat effectiveness was very weak, and many people did not work hard to grind foreign workers, but they were unwilling to risk their lives to attack Jizhou City.

From the beginning of Polu's order to attack the city, the progress of Zhang Rong's army can be said to be very, very slow, often they just launched an attack, the defenders on the city wall counterattacked slightly, they were defeated and retreated, and the angry Polu ordered to kill a lot of rebel officers and soldiers.

In this way, the soldiers under Zhang Rong's command had to strengthen the attack, but their consumption in the first few days also provided Zhang Shi in the city with sufficient time to prepare, Zhang Rong led the soldiers and civilians in the city, strengthened the city wall in a few days, and also built a defense line with the demolished house masonry and wood in the city, and even dug a huge trap pit inside the city gate, which provided a guarantee for a long time of guarding.

More importantly, this time he moved a large number of people into the city, and the people took a lot of grain into the city, plus the previous reserves of Jizhou City, and the batch of grain that had just been received, providing them with nearly three months of food.

This is for Zhang Shi to resist the Mongolian army for a long time to make a relatively full preparation, can also be said to be the situation to create heroes, although Zhang Shi is Peng Yibin's fierce general, but in the entire Jingdong area, he is still a little-known person, and the battle of Jizhou City, but the achievement of Zhang Shi's reputation, making it a bright star of the Northern Army.

Polu obviously despised the small city of Jizhou this time, in his opinion, where the Mongolian army passed, it can be said that it is invincible, and the Mongolian iron hooves do not have an uneven city, seeing that Zhang Rong's servant army can not achieve a big thing, and the siege will be defeated, so they replaced them with the Mongolian army to attack the city, Polu sent his generals to lead the army to attack the city, and the result was a head-long collision, and it was a head-on-head bloodstream.

It turned out that the Mongol army at this time had not yet formed a very strong siege force, and their main force was still the Mongol army, although there were some Khitans and other nomadic soldiers, but the overall siege technology and ability were still lacking, and the main purpose of this Polu southern invasion was to contain Peng Yibin and **'s soldiers and horses in the north for Li Quan, so that they could not cooperate with the Song army to attack Li Quan in the south, and the other purpose was to test whether Jingdong could be placed under the rule of their Mongols. If they really can't do it, they will plunder and return to their prairie, and at present, they have not completely formed the strategy of capturing one place and dominating one place that Mu Huali has promoted.

In terms of overall strategy, the Mongolian army did not plan to fight in Jingdong for a long time this time, otherwise they would not have sent only such a few soldiers and horses.

The main force of the soldiers and horses led by Polu this time was still cavalry, and there were some Jin troops who had surrendered to the Mongols before, and their field combat ability was super strong, but their siege ability was slightly inferior, and there were not many heavy siege equipment, which created a lot of difficulties for their siege operations.

The first siege battle with the Mongol army as the main force, although the Mongols had superb archery, and the generals were even more fierce and fierce, but without the assistance of complete siege equipment, they attacked for two days in a row, only to create heavy casualties for the rebels defending the city, and they themselves were also under the frantic resistance of the rebels, and suffered heavy losses, even a general who was mainly responsible for the attack was stoned alive by the stones thrown from the city, which made the Mongol army's attack a setback, and Polu had to give up such a defeat-losing siege strategy. Instead, it was changed to a siege, intending to trap more than 100,000 soldiers and civilians in the city here.

During this period, Peng Yibin also led the army from Enzhou, intending to rescue Jizhou City, but Polu was good at field warfare, repelled Peng Yibin's rescue army many times in a row, and also caused great casualties to the Yi army, Peng Yibin tried several times, had to give up the rescue of Jizhou, concentrated forces, and resisted the continuation of the Mongol army in Enzhou to the south, and the two armies formed a stalemate in Enzhou and Jizhou.

No one thought that in this siege, the Mongolian army actually besieged Jizhou City for nearly half a year, and it also became a turning point in the war, which shattered the idea of the Mongolian army to occupy Shandong, but this is already a later story, and it will be explained in the future.
