After dark, after deliberation, the spies sent by the Xuanwei army left the empty south gate, and one team went west and the other team went north to reconnoiter the situation of the enemy troops on both sides.

At night, the city was brightly lit, the city gates were closed, and on the first night of defending the city, no one dared to be careless when the enemy would appear.

There was nothing to do in the city all night, but the several battalions of Xuanwei army guarding the city were very tired, and the next day, they were all listless and yawning. This exposes the problem, the Xuanwei army has no experience in defending the city, saying that if the city is defended, the entire battalion will not arrange rotation, and all of them will stand on or below the city, so it is no problem to insist on it for a day, but something will inevitably happen after three or five days.

The next day, the discussion was concentrated, and some problems were solved, one was that the defending army was going to be on duty in rotation, an hour was changed, and when it was not on duty, it could rest in the barracks built at the city gate, but it was not allowed to leave a mile, and the other was the material problem of resting the city wall, and there was no extra masonry in the city, and finally Yang Congyi made a plan, and he could demolish the city wall nearby, and the whole family fled from other people's houses, and there were military and supply problems, and sent 200 people back to the coast to assist the remaining Xuanwei army to move all the remaining military funds over.

Yang Congyi was not idle in the city, either patrolling the city and supervising the repair of the city walls, or studying the maps of Qinzhou and Guangnan. Li Yue's invasion, this is a very good opportunity for meritorious service, if you can seize the opportunity, make great contributions, and then be promoted, there is great hope, at present, it seems that it is easy to defend this city, but it is not so easy for 4,000 people to win additional military merits, and they must turn their vision out of the city, so he urged the spies to go out of the city to find out the news of Li Yueren.

Within two days, all the important military materials and ordnance were transported into Anyuan County, and most of the city walls were repaired, and only three major damages were still being repaired.

The spies sent out sent back the news one after another, the enemy army in the north has reached Tuliang, and the reply is that there are about 1,500 people, there are many rivers, and the movement is slow, and it is expected that there will be three more days to reach Nasuo Town, from Nasuo Town to the east to Huashi Town, there is almost no need to cross the river, half a day can reach Huashi Town, and then to the east to cross a six-zhang wide river, there are fewer boats, 1,500 people all cross the river, it will take at least half a day, and then it will take half a day to directly reach the opposite side of the river outside the west gate of Anyuan County. The news brought back by the spies was very detailed, and if the news was accurate, the enemy army in the north would reach the outside of Anyuan County in four days at the earliest.

The south also brought back more accurate news, the enemy army on the south road is still in Dongxing Town for the time being, they first went east along the coast, and then returned to Dongxing, detoured to the north, and is expected to reach Malu Town, then to Nasuo Town, and then to Huashi Town, and then directly to the west gate of Anyuan County. According to the time of the march, the enemy army on the southern route will be about two days later than on the northern route.

There is also news that there are more enemy troops on the south road than on the north road, the number is estimated to be about 3,000, and they have plundered a lot of property in Dongxing Town, which is difficult to take away, and some enemy troops are left to guard in Dongxing.

After getting these news, Yang Congyi had a bold idea in his heart and took the initiative!

The two armies of the enemy are one after the other, and the difference in itinerary is two days, and the Xuanwei army can take advantage of the time difference of these two days to first attack an ambush of the Northern Route Army, and if the ambush location chosen is good, 4,000 people can completely annihilate all the 1,500 enemy troops, and the ambush location chosen is either before reaching Huashi Town, or when the enemy army crosses the river in Huashi Town.

After destroying the enemy army on the north road, the Xuanwei army continued to ambush the enemy army on the south road to the west. Not to mention much, as long as half of the enemy troops on the southern road are eliminated, the enemy army that invaded Qinzhou this time will be defeated and retreated, and the defense of Anyuan will be over in a few days.

When Yang Congyi told Zhao An about this idea, Zhao An made it clear that he was against it.

He thought that whether it was the enemy army on the north road or the enemy army on the south road, when they arrived at Anyuan County, they were all tired troops, and it was inconvenient to march in the south, so they must not bring much food, as long as they could stop them under the city, without spending a single soldier, and when they ran out of food and grass, they would retreat. If you are not careful, you will lose too many troops, even if you eliminate the North Route Army, you will not be able to continue to ambush the South Route Army, if the casualties are too large, the morale of the Xuanwei Army will be hit, and it is likely to affect the defense of the city in the end, if you can't hold the county seat of Anyuan, Qinzhou will also be lost, and their guilt will be great.

Therefore, Zhao An believes that the most secure tactic is to stick to the city, wait for work with ease, and drag down the enemy army with a strong city, so that the Xuanwei army will not be damaged, and the garrison task can be completed.

But he forgot that the purpose of Li Yueren's arrival at Anyuan County was not to fight the Great Song defenders, and if the siege was blocked, they were likely to bypass Anyuan County to the east and go directly north to Qinzhou. Qinzhou's troops are empty, all the defenders are less than 2,000 people, Li Yueren marched all the way east, the defenders of Anyuan fled when they heard the news, and the defenders of Qinzhou will not be much better, if Qinzhou is lost, the supply of Anyuan County will be interrupted, and then the Xuanwei army will still have to go out of the city to engage Li Yue's enemy army.

If it really happens, the situation will be reversed, the Li Yue people will occupy Qinzhou, and the Xuanwei army will either attack the city or escape by boat if they want to survive. Or the Li Yue people who collected enough grain and grass gave up Qinzhou City, turned back to besiege Anyuan County, Xuanwei army did not break through to death, and the breakthrough was also a defeated division, either go back to Qinzhou, which had nothing, or flee back to the port, but with the cunning of Li Yueren, before the siege, the port fleet would definitely be burned, so after the breakthrough, they could only flee to Qinzhou, which had nothing, if the enemy army could not chase after it, the day when the Xuanwei army ran out of food, was the time of destruction.

Therefore, if the Xuanwei army does not take the initiative to attack and repel the enemy army, and the enemy army does not choose to fight Anyuan County, then the Xuanwei army will undoubtedly be defeated and Qinzhou will be lost.

Suddenly thinking about all this, Yang Congyi suddenly became anxious, and immediately told Zhao An that the Xuanwei army must attack, because they can't guarantee that Li Yueren will fight to the death with them in Anyuan County until they run out of ammunition and food, Li Yueren is not a fool, he can't gnaw Anyuan County, he will definitely adjust his goal and attack Qinzhou City, if the Xuanwei Army wants to return to the division to rescue Qinzhou, it is likely to be ambushed by Li Yueren halfway, if they don't rescue, wait for Qinzhou to fall, and wait for the Xuanwei Army to either flee as soon as possible, or be destroyed after a hard battle, But it is also possible that he failed to escape smoothly and was ambushed and destroyed by Li Yueren halfway.

In a word, if you don't take the initiative to attack and destroy Li Yueren, the best result for the Xuanwei army is to escape smoothly, but it is more likely that the whole army will be destroyed.

Perhaps the county officials and defenders who fled a few days ago saw the essence of the battle clearly and predicted the final result, so they did not hesitate to flee directly from Anyuan County.

For the Xuanwei army, if they do not take the initiative to destroy the enemy, there is still a way to save their lives, that is, like the county officials and defenders who fled before, they retreat to Qinzhou City in time and hold on to the city. Qinzhou City is larger than Anyuan County, the population is also large, the city is strong, backed by Yongzhou, the core area of the eight states in the south of Guangnan, the material will not be cut off, Qinzhou can be defended, then the Xuanwei army can be guaranteed.

But if you want to save your life, you have to lose Anyuan County, which does not match the order received to transfer and defend Anyuan County, even if you hold Qinzhou City, don't think about the military achievements, and if you don't hold it accountable, the court will be tolerant.

After Yang Congyi analyzed the situation faced by Xuanwei Army, Zhao An still hesitated and still said that he would consider it.

Time is pressing, repelling the enemy army, giving the Xuanwei army a fleeting opportunity to fight for meritorious service and survival, once missed, the Xuanwei army will be doomed. In this situation, Zhao An still has to consider, Yang Congyi is angry and anxious, but no matter how anxious he is, he can't make decisions for the commander, after all, any combat order will eventually be ordered by the commander of the first army, he is the supervisor of the army, the commander is alive and well, and he is not seriously ill, so it is impossible to overstep his responsibilities.

In desperation, Yang Congyi told Zhao An that he would only give him one night to think about it, and before sunrise tomorrow, he must have a clear answer to either retreat or take the initiative.

After Zhao An nodded, Yang Congyi immediately left the county office.

Zhao An's performance made him very disappointed, at this critical moment, whether to retreat or advance must be decided quickly, the slightest hesitation, the consequences are unimaginable, especially Xuanwei Army is in this embarrassing situation.

Fortunately, if they chose to retreat, the Xuanwei army would have at least three days to safely return to Qinzhou. But if you want to take the initiative, tomorrow is the last chance, and the day after tomorrow, if you want to attack and ambush the enemy, it will not be so easy, there is not enough time to march, and suitable ambush locations are not everywhere.

In any case, we must make some preparations for the future, and we can't leave the fate of the Xuanwei Army in the hands of Zhao An.

Yang Congyi left the county government and went straight to the camps.

In the past few days, he has been walking around the city very diligently, and his relationship with everyone is gradually getting closer. Before being responsible for returning to Yi to supervise the construction, although he was also named to supervise the army, he was busy everywhere, and occasionally had little contact with everyone in the army. The most familiar battalion commanders, only Zhang Biao and Su Zhong, who went with him to Li Yue's envoy, Zhang Biao stayed in the Zhancheng State and did not come back, at this time, in the entire Xuanwei army, Su Zhong was also familiar.

He first came to Su Zhong's station, and was immediately led into the camp by the sergeant.

"Second Su, what are you messing with? Study*? As soon as Yang Congyi entered the barracks, he saw several disassembled bows and crossbows on the ground.

Su Zhong got up and said with a smile: "I've seen the prison army." ”

"What is this?" Then sit down.

"It's nothing, I just don't understand, why the crossbow doesn't shoot far, just disassemble a few crossbows and see what the problem is." Su Zhong scratched his head and sat down.

"It's good to be able to think about the problem, but I'd better have time to study this bow and crossbow later. Let me start with a question, and you think about it now. Yang Congyi said with a smile.

"Excuse me." Su Zhong sat up straight.

"Don't be so serious, today I suddenly remembered this problem, let's study it together. Why did Li Yueren have to attack Anyuan County? ”
