Standing on the city wall, Yang Lin watched the battle situation with a telescope from time to time, and saw the defeated Gao Wengui, Wang Jiye, Wang Zhibang and other departments, and the elite strength of the Great Western Army still exists, and now it is raining lightly in the sky, and there are basically few thunderstorms in the battalions on the front line.

Worried about being ambushed by the Great Western Army, Yang Lin categorically refused the request of Bu Ning and Yao Chonglie to increase the troops, ordered Mingjin to withdraw the troops, and the troops slowly entered the fortifications.

Collecting troops and returning to the camp, seeing the heavy casualties of the siege departments, Zhang Dingguo was quite annoyed, although there were guards against the use of earth-shaking thunder by the volunteers, but he did not expect Yang Lin to use the earth-shaking thunder to the extreme, just charged and threw out hundreds, the whole charge reached more than 3,000, it can be said that there is one per person, which is unimaginable for the ancient dense formation.

With the earth-shattering thunder and explosions one after another, it was difficult for the Great Western Army to form an effective formation on the battlefield, and it was constantly rushed and killed by the volunteers, just because of the small amount of manpower invested, coupled with the possibility of a gloomy sky, otherwise the Great Western Army would definitely be disrupted.

After collecting the troops and returning to the camp, the camp sighed and sighed, and everyone dared not be careless about the continuous tactics of the volunteers, and some people pondered how to get out of danger.

Jin Tongwu, Wang Zhibang and others said frankly that although the strength of the Great Western Army was several times that of the Volunteer Army, the main force was only the pro-army under the jurisdiction of the generals of each department, and the number was less than 20%, which was the same as the number of people on the other side.

In addition, the most unfavorable thing about the battlefield is that the frontal position is narrow and difficult to unfold, Shunqing City faces water on three sides, and only the north side is relatively open, but even so, it is also hilly and dense, and there are many ravines.

When Bai Wenxuan, the governor of the left army, heard this, he hurriedly dissuaded him, if nothing else, he needed to fight to eliminate Zhang Xianzhong's dissatisfaction.

At the beginning of the year, the Great Western Army entered Hanzhong and was defeated by He Zhen, Zhang Dingguo led his troops to evacuate, and finally was beaten with 30 military sticks.

As long as the war lasts and there is no food and grass at that time, it is not too late to withdraw.

As the saying goes, soldiers and horses go first before grain and grass are moved, and the main thing in a war is money and food, especially in ancient battlefields.

Carrying a single person on a shoulder can only transport 6 buckets of grain, and a wheelbarrow is no more than a load of grain, according to the consumption of 3 liters of grain per person per day, a person carrying a shoulder on the shoulder can only supply one person for ten days, and a wheelbarrow can only supply one person for fifteen days.

The two sides have been in a stalemate for more than 10 days, and the grain they brought has already been exhausted, and now they have been urging grain back and forth many times to loot grain from the people.

Not to mention that the food is okay, when it comes to food, Zhang Dingguo is full of complaints.

Just as the modern army relies on vehicles to ensure rapid mobility, in the late Ming and early Qing dynasties, the Liukou mainly relied on animal power to ensure the rapid mobility of the troops.

In the past, whenever they occupied a place, they would collect livestock from the people, the best horses, mules, and the worst cattle.

In the past, mobile warfare did not stay in one place for a long time, and the damage was not too obvious.

Since entering Sichuan and taking Sichuan as the base, the destruction of a large number of looting and animal power by the rebels has become more and more obvious, and some even frankly admit that it is more unacceptable than directly killing people and setting fires than robbing homes and houses.

Agrarian civilization mainly relied on domesticated animal power for farming, and after being plundered livestock, some people had to replace ploughing cattle with people, but the cultivated area was less than one-tenth of the animal power.

Due to the large area of the Great Western Army, the protracted plundering of the people's cattle, the cultivated area of the land plummeted, and the level of land cultivation was completely degraded.

Everyone was gloomy for a while, and Zhang Dingguo sighed for a long time: "The army is under the city, and the daily cost is very huge, in order to supply the military supplies at the front, it is still too late to levy more than 10,000 people to transport grain and grass from Tongchuan Prefecture and Xichong County.

Now that the land has been seriously abandoned and displaced people are everywhere, it is not a pity to delay major events just because of the fear of punishment. ”

Everyone was shocked, now Lao Wansui's temper is getting more and more irritable day by day, if he hears that General Dingxi retreats without a fight, he will definitely be severely punished at that time.

Everyone strongly invited, Zhang Dingguo sighed several times, and agreed to postpone the matter of withdrawing the army for two days.

The next morning, Zhang Dingguo convened the generals again to discuss the retreat, and suddenly there was a commotion from the Chinese army.

Zhang Dingguo governed the army very strictly, not to mention the big tent, even the other battalions did not dare to make noise, just when everyone was at a loss, the governor Wang Jiye came to report, and a raging fire was ignited in the southwest direction.

Zhang Dingguo was shocked, and hurriedly led everyone to climb the mountain to look into the distance, and saw the smoke billowing from 60 miles away, and the flames soared into the sky.

The direction of the fire is where the grain turnover of the Great Western Army is, and there are nearly 10,000 loads of grain and grass in the post station.

Since the beginning of the year, there has been a general feeling of food shortages in all parts of the country, as hundreds of thousands of troops from the Great Western Army have entered Sichuan, and the flooding of the CD Plain, coupled with the unrest in various places, has sharply reduced local production.

In order to solve the food shortage, the Great Western Army forcibly recruited the gentry and large households into the CD, and by the way, their grain and grass were used for military purposes, so as to alleviate the food shortage slightly.

Despite this, there were too many soldiers and horses in the Onishi army, and many soldiers could only eat two meals a day, and did not dare to eat and drink as much as in the past.

Now seeing the volunteers attacking the rear grain road, everyone was shocked, and everyone could no longer care about Zhang Xianzhong's punishment and decided to withdraw from the army.

In order to protect the grain in the rear, Zhang Dingguo sent Bai Wenxuan, the governor of the left army, to lead 3,000 elites to go first, and personally led 5,000 pro-troops to retreat, and the army slowly withdrew to Tongchuan Prefecture.

Bai Wenxuan led his subordinates to the ferry and was about to cross the river, when he suddenly saw twenty or thirty boats downstream, shelling the Great Western Army from a distance.

Bai Wenxuan was shocked and hurriedly organized troops and horses to counterattack, but most of the opponent's naval troops were all firing guns in the waterway, and they did not dock at all.

Worried about the battle ahead, Bai Wenxuan left a small number of troops to entangle here, and personally led the main force to a shoal upstream to cross the Xixi River, so that he could walk an extra forty miles.

Now is the troubled times, food is not food, but everyone saves lives and saves lives, Bai Wenxuan is about to lead his troops to protect the grain road, and suddenly received a military report, more than 1,000 Western troops left in Xishan were attacked by the volunteers before and after, and now they are defeated.

It turned out that seeing the raging flames of the rear post station, Jin Tongwu, the governor of the camp, was shocked, there were nearly 10,000 loads of military rations for the Great Western Army, and no food in troubled times meant failure, which meant that the army collapsed.

Jin Tongwu felt a heavy responsibility, the volunteers were surrounded in Shunqing City, outside the city there were only 2,000 volunteers on the West Mountain, they relied on the terrain of the West Mountain to defend in danger, and now the grain in the rear was burned, it must be no different from the volunteers on the West Mountain.

Leaving the deputy general to lead 3,000 soldiers and horses to camp in front of the West Mountain, Jin Tongwu personally led 2,000 elites to protect the grain road.

The lieutenant general who stayed behind was worried for a long time, and in the evening, the volunteers suddenly rushed down from the western mountain.

The deputy general was shocked, and hurriedly led his subordinates to meet the attack, and at this time, hundreds of cavalry suddenly came out from behind.

Suddenly, the volunteers were attacked before and after, and the Great Western Army was defeated, and everyone scattered and fled, so the rout met Bai Wenxuan on the way.
