Ouyang Xuan believed that Pu Ze's move by the Sichuan troops in the Southern Song Dynasty to counterattack Chengdu was a major event in the fight against Mongolia. This battle not only related to the gains and losses of the entire Xichuan, but also had a great relationship with the future of the Perak Army. He must not stay out of it. However, Wanjiazhai was in Chongqing.

Xinjin City is in the northwest of Chongqing Prefecture, and Xinjin City is in the southeast of Chongqing Prefecture, at both ends of the long and narrow area of ​​Chongqing Prefecture. If you go to Xinjin Village in peacetime, you can take a boat down the Wenjing River in Hengyuan Village and go there in one day.

It can be reached. However, since the Mongols took control of the Chongqing Fucheng Navy Pier, which must pass through the waterway, the waterway has become unfeasible. And if you want to go around the prefectures and counties occupied by the Mongols, the distance is too far and it will take at least half a month.

Time. This is also the reason why the messenger team sent by Pan Tongzhi chose to take the risk and come through the Mongolian-controlled area. There are enemy cavalry patrols on the official road in the Mongolian-controlled area, but there are many rivers and mud outside the official road, and the paths are secretive and difficult to find.

It is easy to get lost. Just going to Xinjin City to make contact. Although the journey is difficult and dangerous, it is a risk that has to be taken. Ouyang Xuan thought about it again and again and decided that Dong Hu would lead his people to Xinjin City to meet Pan Tongzhi. In addition to Dong Hu’s high martial arts skills, he also had to take the risk.

Because he had gone to Chongqing Mansion many times and often delivered valuable mountain products on behalf of the Perak Army, he was relatively familiar with Pan Tongzhi. More importantly, he did not show his face during the expulsion of Pan Luohuan and had no contact with the Chongqing Mansion Yamen.

People create hatred.

After receiving the mission, Dong Hu found Le Quan'an and asked him to describe the situation along the road in detail and draw a sketch of the path. He did not take Le Quan'an back to Xinjin Village this time, except that his origin could not be proven.

His body was also severely overdrawn when he arrived, and he could not withstand high-intensity operations in a short period of time. Moreover, when traveling through the Mongolian-controlled area, the smaller the number of people, the smaller the chance of being discovered by the enemy cavalry, so Dong Hu only picked four in the reconnaissance company.

As elite companions, these four people are not only agile in martial arts but also skilled in the use of grenades. In order to enhance the combat effectiveness of these four people, Ouyang Xuan also asked them to bring a new type of grenade that was just trial-produced by the research institute, but there were only a few of them.

Two. The difference between the new grenade and the old grenade is mainly in the firing method. When using the old grenade, you need to open the cover, light the fuse with fire and then throw it out. It is not only troublesome to use but also has a high rate of duds. Learn how to use it.

The firing time is also longer. The new type of grenade does not require the use of tinder. You only need to open the cover and pull the fuse, which is detonated by the mercury fulminate inside the projectile. It is not only easy to use, but the dud rate is also greatly reduced. However, because it still uses granular black powder

, the charge amount has not been increased, and the power is not much different from the original model grenade.

After Dong Hu went to Xinjin City, his duties were temporarily replaced by Huang Dagen. In order to cope with the changes in the situation, know yourself and the enemy, and fight every battle, the Perak Army urgently needed to master the current situation information outside the mountain. It turned out that many of the Perak Army's spies were nearby.

Yongkang, Hengyuan and other places in Yongkang, Hengyuan and other places have very little information about distant places. Especially after the arrival of the Mongols, contact with Chongqing Mansion and other places was also cut off. According to Ouyang Xuan's arrangement, the Internal Guard Battalion needs to send out reconnaissance personnel

To find out the information about the Mongols in the Western Sichuan Plain within 200 miles of Wanjiazhai, this includes more than ten prefectures and counties including Chengdu Prefecture, Chongqing Prefecture and Qiongzhou. For this purpose, the Internal Guard Battalion sent elites to form more than ten detachments.

The reconnaissance team is a group of five or six people disguised as refugees and other people of various colors and sneaks into various places to conduct reconnaissance.

Although there were twists and turns when Dong Hu and his party went to Xinjin City, and it took a lot of time to hide and hide along the way, they arrived at Xinjin City on the fourth day after departure. This was partly because all five of them were hunters and had strong survival skills in the wild.

On the other hand, it also benefited from the simple map drawn based on Le Quan'an's words, which helped to avoid the Mongolian troops patrolling the official road - this indirectly confirmed the identity of Le Quan'an's envoy's entourage, and Pan Tongzhi also confirmed

What he said is not false.

When Dong Hu met Pan Tongzhi, in addition to presenting the letter from the Perak Army, he also presented mountain goods-leopard skins and deer antlers as usual. It is probably because of the strength shown by the Perak Army after defeating the new vassal army that Pan Tongzhi treated Dong this time.

Hu and his party were polite and agreed to Ouyang Xuan's idea of ​​taking Yongkang City first and then jointly attacking Chongqing Fucheng. When Pan Tongzhi asked about the details of defeating the new vassal army, he both praised the thunderbolt weapons and lamented that Ouyang Xuan was the king of the country.

Dong Liang finally asked about the making methods of grenades and artillery. After Dong Hu was silent for a while, he deduced that the method of making firearms was taught to craftsmen by Ouyang Xuan himself.

Pan Tongzhi asked Pan Tongzhi for the craftsmen of Xinjinzhai to imitate. Seeing that Dong Hu was reasonable, Pan Tongzhi did not have any doubts. He only said that when the traffic became smoother, he would ask the Perak Army to send some artillery and craftsmen, and let the Chongqing Prefecture Xiang Army also

Equip yourself with these weapons.

Dong Hu has a natural acumen for military affairs, which is why Ouyang Xuan chose him as the intelligence chief of the Pili Army. By walking around and wandering around, he was able to clearly understand the situation in Xinjin City in a short period of time. This Xinjin

The city is located at the intersection of three major rivers: the Nanhe River, the Wenjing River and the main stream of the Minjiang River, the Jinma River. It firmly controls the waterway for the Sichuan Mongolian Army to move south to Meizhou and Jiading Prefecture. Its geographical location is extremely important. The Mongolian Army attacked cities and captured territory everywhere in western Sichuan.

The situation was overwhelming, but several attacks on Xinjin City failed. In addition to Xinjin City being surrounded by water on three sides, the river was wide and deep, making it extremely easy to defend and difficult to attack, a powerful naval force was stationed here.

The Mongolian army is not good at water warfare and can only attack from land, but it is blocked by the tall city wall. Moreover, the moat of Xinjin City is more than ten feet wide and is connected to the river surrounding the city. When the Mongolian army attacks the city wall from land, it will be attacked by two enemies.

The navy on the side attacked, and the siege equipment was repeatedly destroyed by the ballistas and trebuchets on the navy ships, so they had to retreat in frustration. The Mongolian army could not take Xinjin City, so they could only detour to attack Meizhou and Jiading Prefecture downstream. They only transported baggage by land.

The pressure was too great, and the naval forces of Xinjin City and Pengshan City downstream used the Minjiang waterway extending in all directions to attack the logistics, allowing the Mongolian army to attack Meizhou, and Jiading Prefecture also suffered repeated setbacks.

In Pan Tongzhi's boast, he recently commanded the navy of Xinjin City to go up the river and attack Qiongzhou, Dayi, Wenjiang, Pixian, Qingshen, Daojiang, Yizheng and other prefectures and counties along the river. If not

The Mongolian cavalry is fast and mobile and will surely be able to recapture some states and counties. After hearing Pan Tongzhi's statement, Dong Hu disagreed. He knew that the navy might succeed in a sneak attack, but it would be difficult for the infantry to defend the city because it was difficult for the infantry to defend the city.

He observed that the combat effectiveness of the Xinjinzhai infantry was not much better than that of the new auxiliary army that invaded the mountains. Because he did not understand water warfare, he could not evaluate the combat effectiveness of the navy. More importantly, even he, an outsider, could vaguely see the difference between the infantry and the infantry.

Xinjin Village now has 2,000 infantry troops and 1,000 navy troops. The infantry was mainly brought from Chongqing Mansion by Pan Tongzhi, and his generals were all his confidants. Chongqing Mansion originally had 3,000 infantry troops.

People, when Pan Tongzhi retreated, he left a thousand old and weak soldiers and the occasional rebellious generals to defend the city. However, those who were abandoned were not willing to defend the city. They either ran away and became bandits or surrendered to the Mongolian army and navy.

It was the original garrison of Xinjin City. Although it was nominally under the command of Pan Tongzhi, it was its own group. The navy originally had 1,500 people, but under the command of Pan Tongzhi, it was reduced by one-third after several battles, and even the original
Chapter completed!
