Ouyang Xuan and Yang Bangxian stood on the top of the Sandu Water Fortress, watching the Mongol army on the other side of the river retreat like a tidal wave. Although his face was calm, his heart was turbulent, to be precise, he was afraid. At this moment, the fog has dissipated, and every move of the Mongolian army on the east bank of the river can be clearly seen. As soon as the secret man Huoli took his Mongolian cavalry away, the Mongolian Han army under Liu Heima also followed in the direction of Wenjiang City, and now only a few hundred new annexes and civilians were left on the beach in the river. It's not that they don't want to escape, but because the pontoon bridge has been completely blown up.

Although the section of the river where the pontoon bridge was built was very narrow, it was also more than ten meters wide. This distance is not a problem for those who are proficient in water, but it is difficult for those who cannot swim. What's more, even if you can cross the river and get soaked all over, whether you can escape to Wenjiang City, more than 20 miles away, and survive in this cold and biting weather is another matter. In this war-torn era of malnutrition and lack of medical treatment, headache and brain fever may be a ghost door for ordinary people. While the soldiers and men of the new annex were buzzing together in front of the blown pontoon bridge, a large number of Perak soldiers shouted "Kill the resisters, surrender and die" and pounced down from the embankment.

Without any suspense, most of the people in the river beach and the new annexed army fell to their knees. Only a small number of soldiers of the newly annexed army swam to the other side at the risk of their lives, and these people were either hardcore traitors or had the blood of innocent people on their hands, knowing that there would be no good fruit to eat if they surrendered. Ouyang Xuan attached great importance to the political propaganda offensive, so after a few battles at the beginning of his rise, the new annexed army in western Sichuan knew about the capture policy of the Perak army. In the eyes of the new annexed army, being a prisoner will definitely go to the underground mine to mine, but there is food and clothing, and he can be cured if he is sick, but it is not much worse than the days when the new annex army licks blood with a knife. Speaking to be a lackey of the Mongols, he can only barely eat and clothe himself, and it is common to be beaten, scolded and bullied on weekdays, and he has to be cannon fodder in wartime.

When Huang Dagen led people to capture the prisoners and let them completely destroy the pontoon stumps, a team of Mongolian scouts appeared on the east bank embankment, and there was a faint sound of thunder in the distance. Ouyang Xuan, who was standing at the top of the fortress, faced the muffled thunder and raised the telescope hanging on his chest. The camera zoomed in, and I saw a black crushing cavalry on the northeast horizon, with huge smoke and dust rising behind him. These cavalry were the Mongolian cavalry from Chengdu and Pengzhou. As these cavalry got closer and closer to the river bank, Ouyang Xuan even saw that the horses that were rushing forward had their nostrils turned out, sweating profusely, and the horse's hooves were rolling up large pieces of field mud and grass stalks of wheat seedlings.

Before the cavalry of the brigade could reach the range of the fortress's cannons, the group of Mongol scouts on the embankment turned their horses and turned back. The pontoon bridge was broken, and the surprise plan had failed, so a few moments later, the Mongol cavalry rode away in the direction of Wenjiang City. It is said that the momentum of the three thousand cavalry galloping at the same time is very amazing, and the sound of tens of thousands of horses' hooves stomping on the ground is like thunder, and even Huang Dagen, who is in the river beach, feels the earth trembling slightly. After more than ten minutes, the Mongol cavalry had disappeared, and only the choking smell of dust in the air and a mess of wheat fields could prove their existence.

The Mongol cavalry came and went, much to Yang Bangxian's chagrin. When he saw that the cavalry was out of range of the artillery, he stopped, and stamped his feet in a hurry. The 12 heavy cannons of the Sandu Water Fort just now showed their might, not only blowing up the pontoon bridge, but also beating the Mongolian troops assembled on the east bank to the ground, which made him very relieved. It's really decompressing to think of the scene where the fortress's heavy artillery bombards the cavalry at the same time, and the shells fall into the dense enemy! Now that the barrel has cooled down and is ready to fire, how can he not be annoyed that these cunning Tartars are far out of the range of the artillery? What he didn't know was that the Mongol cavalry had enough of the suffering of artillery as early as the Battle of Yokohara Fort. Since then, there has been a consensus among the top brass of the Sichuan West Mongol Army that they will never attack the Perak Army's forts with heavy artillery, especially those guarded by gunboats.

The so-called "newborn calves are not afraid of tigers", the retreat of the Mongolian cavalry made Yang Bangxian unwilling, but made Ouyang Xuan and Huang Dagen and other personnel feel happy. If the Sandu Water Fortress had not been recaptured, and if the pontoon bridge had not been destroyed, the three thousand Mongol iron horsemen would have no strength to stop them from galloping across the plain. Thinking about this consequence made Ouyang Xuan's back chill. Although this time, the Mongolian army was able to successfully attack the Sandu Water Fortress by taking advantage of the dark night and fog in the dry season, there were many luck elements. However, the trend of war and history is inherently random, and it is greatly affected by contingencies. The current Thunderbolt army simply cannot withstand the serious consequences of such an accident. To mitigate or even avoid this impact, the premise is that you must have enough strength to resist risks and improve the fault tolerance rate.

This battle is extremely passive in terms of strategy, and the process is terrifying, but it is also thrilling, and there are even great gains in terms of results. In addition to the more than 300 Mongol and Han soldiers who were wrapped in dumplings in the fortress, more than 600 people were captured in the sandy beach in the river, including more than 200 new troops and more than 400 people. Most of these people went to the mines, but the difference was that the people generally only served hard labor for less than half a year, while the new annexed army and the Mongolian and Han armies generally served hard labor for more than five years, and some even served more than 20 years. In addition to the nearly 1,000 strong laborers, the Thunderbolts also captured a large amount of logistics on the east coast. Most of these supplies were piled up near the river embankment, within the range of the fortress artillery, and the Mongol army did not dare to come back and loot them.

The losses on the side of the Perak army were not large, except for the basic casualties of the fortress garrison company, the troops, including the 2nd Teaching Battalion, only suffered more than 100 casualties, most of which were arrow wounds, and most of them were minor wounds. This is mainly due to the dense fog that made the Mongolian army unable to give full play to the advantage of bows and crossbows, but was beaten by the grenades of the Thunderbolt army, and the twelve heavy guns of the fortress also killed and injured a considerable number of Mongolian troops. However, in this battle, the Thunderbolt Army threw thousands of grenades, and also consumed hundreds of artillery shells and a large number of mines and other military supplies, which were also very valuable. Huang Dagen roughly calculated the price, which surprised Yang Bangxian. He now finally understood the meaning of Ouyang Xuan's frequent reciting of the phrase "Fighting a war is fighting the economy". Before, he secretly laughed in his heart that his brother-in-law was so childish, and he often talked about money and property.

After cleaning up the battlefield, the troops directly under the General Staff took the prisoners to Jiangyuan City, where they were to take a boat to Dayi and Qiongzhou to serve hard labor. Since the garrison company of the Sandu Water Fortress has been wiped out, its defense will be taken over by the 2nd Battalion of Teaching until a new garrison arrives. The second battalion only suffered seven dead and more than 20 wounded in this battle, which was still fully manned, and it was more than enough for them to defend the Sandu Water Fortress. Moreover, the naval brigade has sent light gunboats to reinforce it, and the Mongolian army has no possibility of building a pontoon bridge to cross the river. The garrison of Chongqing Mansion returned to the city with Ouyang Xuan and Huang Dagen. Fucheng is the center of the Perak Army, a center of political and economic scientific research, not only gathering a number of factories and businesses, but also the location of family members, which really cannot tolerate the slightest loss.
