After the order was issued, Gao Yuan and Li Yinghong also led the Xiao cavalry army and Shengjie army of the Wu'an Army from Daijun, and after a day's march, they arrived at the side of Zhuwenze.

At this time, there was only a little more than a month before the last battle, and many soldiers were revisiting the old places, and the battle more than a month ago was still vivid, so there were some feelings. The soldiers who did not participate in this battle inquired about the situation of this battle one after another, and listened to the soldiers who participated in this battle pointing fingers and boasting about how bravely they killed the enemy in this battle.

Three days later, the soldiers of the Wu'an Army arrived at Zhuwenze to converge, and the plateau gathered all the soldiers and announced to them that the purpose of this time was to attack the Xiongnu's Yinshan camp. When the soldiers heard this, they cheered.

Because in the past year, the Wu'an army has successively defeated the Yan State and the Xiongnu, and has achieved great results, and the morale of the whole army is very high. The people of Zhao were originally brave and belligerent, and after the victory, the soldiers who participated in the war were very richly rewarded, so the whole army had a kind of war-seeking mentality, as soon as they heard that this raid on Yinshan was to attack the Xiongnu, everyone was immediately excited, and the risk of raiding Yinshan, the soldiers did not know much, and few people thought about it.

Seeing that the whole army was full of energy, Gao Yuan was also very happy, and after resting for the night, he led the army to set off.

However, more than 30,000 troops, nearly more than 100,000 war horses, of course, the movement is not small, and it is impossible to march at the same time, so Gao Yuan also ordered that the four cavalry armies march in the front and rear and left and right respectively, and the two infantry armies are in the middle, with a distance of about ten miles between the front and the back, and a distance of about five miles from the left and right, and advance separately.

Once the herdsmen of the Xiongnu were found on the road, they were all killed on the spot. Although this approach is a bit cruel, it cannot be soft at this time, because this time it is a surprise battle, and the most important point is suddenness, to hit the Huns by surprise, and when the Huns have not yet found out, they will kill the Xiongnu's Yinshan camp. If the Xiongnu knew in advance and were ready to fight, then the surprise battle would have become an encounter, and even if the Wu'an army could still win, it would have suffered a lot of losses. Therefore, in order to hide the whereabouts of the Wu'an army, it is necessary to be foolproof. The Xiongnu herdsmen I met on the way could only complain about their bad lives.

After the army set off, it went straight to the north, walked for two days, and went around to the north of Yinshan, and then the army turned westward and advanced along the Yinshan Mountain Range, because the route of the march had been set in advance, and there were also lakes and rivers and other water sources along the way, and the luck of the Wu'an army was also very good, and there was no bad weather such as rain and snow along the way, so the march was very smooth, and on the sixth day, it met with the personnel sent by Jiang Huanwu to respond.

This is already the edge of the Xiongnu camp, about 120 miles away from the Xiongnu camp in Wuliangsuhai, and Jiang Huanwu's camp is also located here by a small river. Because Jiang Huanwu and the others are not Huns after all, if they go too deep into the Huns' camp, then the possibility of being exposed is greater, Jiang Huanwu does not dare to take this risk, it is safer to be stationed on the edge.

Of course, the marginal area also has the benefits of the marginal area, Jiang Huanwu has found a hidden garrison area for the army, it is in a valley in the Yinshan Mountain Range, this place is very hidden, can accommodate more than 100,000 troops, and there is a small lake in the valley, it is very suitable for the army to be stationed here. Therefore, after meeting with the army, Jiang Huanwu led the way and led the army to the valley.

At this time, the army had been on the road for five consecutive days, and the average distance traveled every day was more than three hundred miles, although there were two horses to transfer, but by this time they were already sleepy and tired, and they really needed to find a place to rest, so after entering the valley, the soldiers dismounted their horses and unsaddled their armours and rested on the spot.

Gao Yuan looked at the environment here, surrounded by mountains on three sides, and one side was an exit, if you didn't go nearby, you wouldn't have found that tens of thousands of troops were hidden in this valley. And the area of the small lake is not large, but it is enough for the soldiers to drink. It is indeed a good location to stay and rest. However, although this valley is very hidden, the plateau still does not dare to be careless, because the closer to the Xiongnu camp, the more cautious it must be, in case the whereabouts of the Wu'an army are exposed due to carelessness, it will be a waste of previous efforts. Therefore, the soldiers who guarded the valley were still arranged, and a considerable number of soldiers were left in the valley, ready to fight at any time. And the plateau also released two kestrels into the sky to keep them on guard in the air.

After arranging these things, Gao Yuan negotiated the next plan with Li Yinghong, Jiang Huanwu, Yuan Xuan, Ling Feng and others.

Jiang Huanwu spread a map on the table and said: "We are still about 120 miles away from Wuliang Suhai here, but now the Xiongnu are divided into several parts and stationed, and from here to the west, about 30 miles away, there is a Xiongnu camp, the number of people is about 15,000, just on the passage to Wuliang Suhai, no matter how we choose the road, it is impossible to avoid this camp." ”

While speaking, Jiang Huanwu also pointed on the map, and also picked up a few small stones, put them on the map, and signaled the location of himself and the Huns. And everyone looked at the map and listened to Jiang Huanwu's speech, and their faces were not very good-looking, because the Hun camp blocking the road was still more than eighty miles away from Wuliang Suhai. Even if the Wu'an army defeats this Xiongnu camp as quickly as possible, it will take an hour or two, and during this time, the Huns can completely rush to Wuliang Suhai, report to the head of the Youxian Wang, and gain a certain amount of time to prepare, which will be very troublesome.

Li Yinghong muttered, "What can I do about this? After finishing this camp, we can only fight hard with the main camp of the Huns, and in one or two hours, the Huns will not be fully prepared, and we still have a great chance of winning. ”

Yuan Xuan also nodded and said, "I think that's the only way to do it." ”

Gao Yuan smiled and said, "Do we have to attack this Xiongnu camp?" The grassland is so big, and the place is so wide, I can completely bypass this camp and go directly to attack the main camp of the Huns. ”

Yuan Xuan said: "Of course it's okay to bypass this camp, but if we bypass this camp, won't that leave a big trouble behind our backs?" If the Hun army in this camp had been killed from behind us after we had bypassed, wouldn't we be in danger of being attacked from the belly? ”

Gao Yuan smiled: "I have inquired, now the Huns are scattered and grazing, all the food for the winter, it is not easy to gather, even when we pass, the Huns began to gather troops, it will take at least one or two days, and this time is enough for us to attack the main camp of the Huns." After we have defeated the main camp of the Huns, we will turn back to meet this Hun army. After a pause, Gao Yuan said: "But in this way, we are still facing great danger, because if we can't quickly break the main camp of the Huns, we will also face the enemy on the back of the belly, so we must show the courage to fight against the water and break the main camp of the Huns in one go." ”

Li Yinghong was a little confused and said, "I know in one go, but what is a backwater?" ”

Gao Yuan then remembered that the battle of the back of the water was still more than 20 years later, commanded by Han Xin, and there is no such word yet, so he explained: "The art of war: put the place of death and then live, the back of the battle, there is no way back, so the soldiers will fight to the death, win more with less, and defeat the strong with the weak, which is called the battle against the water." Although we are not in a back-to-back formation this time, we are also suffering from the enemy on our backs, so this battle must fight to the death in order to break through the main camp of the Huns, and then turn back to meet the Hun army behind us and achieve a comprehensive victory. ”

Yuan Xuan nodded and said: "Yes, I think this is the only way, we will bypass this Xiongnu camp and directly attack the main camp of the Xiongnu, I believe that these soldiers will be able to break through the main camp of the Xiongnu and achieve victory." ”

Li Yinghong said: "Well, I also think this is feasible, so let's do it." ”

Gao Yuan nodded and said: "Okay, then everyone has a good rest today, we will set off early tomorrow morning, all the baggage will be left here, and the whole army will travel lightly and kill the main camp of the Huns in one go." ”

Yuan Xuan agreed, and immediately went to arrange for the soldiers to rest. Gao Yuan said to Jiang Huan again: "Brother Jiang, our soldiers are exhausted when they arrive here, so the matter of guarding the sentry mainly depends on you people." ”

Jiang Huanwu said: "Don't worry, I have already arranged it, in the valley ten miles away, the brothers have pretended to be herdsmen, once they find that there are Huns approaching the valley, they will use wolf smoke as a number, we can be prepared." ”

Gao Yuan nodded and said, "Brother Jiang really thinks thoughtfully. ”

At this moment, I heard a few crisp falcon chirpings in the sky, and I saw that the two kestrels had lowered their flight altitude and circled up and down. The face of the plateau has changed dramatically, and the kestrel has noticed that someone is coming in the direction of the valley. Could it be that he has just arrived in this valley and is about to be discovered? Therefore, Gao Yuan also immediately instructed Li Yinghong: "Yinghong, quickly mobilize people and horses, attack immediately, and never let a person go." ”

Li Yinghong agreed, and was about to mobilize the army, but Jiang Huanwu stopped them and said, "Don't worry, look, the wolf smoke has risen." ”

Sure enough, seeing a dark gray wolf smoke rushing straight into the sky in the northeast direction, Jiang Huanwu said: "There is only one wolf smoke, which means that there are not many people here, and it should be easy to deal with." ”

Gao Yuan said: "Even if the number of people who come is small, we still have to bring a little more people to be prepared." ”
