Zhang Song took the secret letter and read it quickly. His heart sank, but he immediately understood that this letter was hard-earned. After reading it, he closed it naturally and gave it back to Yan Yan. Then Yan Yan showed it in front of
Liu Zhang's face shook superstition to dust.
"We raised our troops overnight, and apart from anything else, we must first make up our minds!" Liu Zhang said very seriously, "Zi Qiao, please stay and make preparations to recruit Yizhou civilians to ensure smooth logistics."
"As early as last year, I had already transferred grain and grass to the counties and cities along the route to the southwest. General Yan only needed to carry three days' marching grain and grass from Chengdu, Shu County to Guangdu, and then carry three days' military grain from Guangdu.
Go to Wuyang, and then go to Nan'an with provisions and go all the way south." Zhang Song immediately promised that Zhang Song had made arrangements as early as last year when he recruited elite troops to return to Chengdu.
Since ancient times, soldiers and horses have moved ahead with food and fodder. Only when there are no problems with logistical support can the army advance smoothly. The biggest problem with labor expeditions is the difficulty of logistical support and possible problems with acclimatization.
The latter can be forcibly overcome by relying on the current recovery of the essence of heaven and earth, while the problem of the former is a trouble that has always existed until now. As long as humans are still carbon-based creatures and need to eat, logistics is indispensable.
Another big problem with the logistics of ancient labor expeditions when roads were blocked was the one-hundred-fifty-day limit. If the previous place where supplies were transported was more than one hundred and fifty days away from the place where supplies were needed, basically the expedition would be enough.
give up.
The reason is very simple. Whether transported by oxen, horses or manpower, these things themselves need to be eaten. For a distance of 150 days, the person transporting the supplies alone needs to eat 300 kilograms of things. Oxen and horses can transport more.
More, but you will eat more.
In mathematical terms, there will be a limit distance, that is, there will be a limit time for the maximum amount of supplies these people can carry and the amount they consume in a single day.
There will also be a cost ratio, which is the so-called question of whether it is worth eating less on the road than transporting it. Generally speaking, half of the food eaten on the road and half sent over is the limit that the war can sustain.
Of course, Emperor Qin and Emperor Wu both had situations where they ate 90% of their food on the road and only had 10% when they were sent over. I will kill you too.
That’s why there is a saying in the art of war: eating the enemy for one minute and defeating me for ten minutes. However, relatively speaking, the more supplies the logistics transport team eats, the faster they transport them.
Hurry, after all, fewer things will be easier to transport.
Generally speaking, an army carrying three to five days of dry food, as long as the quality of the dry food is reliable, only needs to solve the drinking water problem, and there is no need to carry logistics. An army carrying about seven days of military food can guarantee its own marching speed and will not be carried by the baggage train.
drag.
From Shu County to the Indochina Peninsula, Zhang Song committed suicide once and came back to solve the problem of sending troops again. It would take five months to really transport supplies from Shu County as logistical support. If something happened on the front, Shu County would have to recruit troops and prepare for war.
In the past, Zhang Song calculated the time and felt that the day lilies were probably all gone, let alone cold.
Therefore, the first thing Zhang Song did when he returned from fighting last year was to solve the logistics problem. Logistics and transportation must not be allowed to become a problem that restricts the marching speed.
At that time, Zhang Song could only think of two ways. One was to build roads, but save the money. The construction near Chengdu has not yet been completed. The Han-Chengdu Expressway in the north has not been completed. This is not a question of money, it is directly a matter of manpower.
The problem.
Zhang Su, Wang Lei, Huang Quan, and Li Hui were busy building a road from south-central China to Chengdu. Now, let alone starting the construction, it has not even been put on the agenda. Those unlucky kids are crossing the southwest and arriving.
Now we still need to dig into the woods.
Naturally, the plan with the most execution value was eliminated due to manpower, so Zhang Song could only use his brain power. While dealing with the political affairs of Sichuan and Sichuan, he was thinking of ways everywhere, and finally accidentally came up with a word called light disease preparation.
Why is the army marching so slowly? To put it bluntly, it is because when the army is marching, it is necessary to ensure that the slowest part does not get out of touch, so the entire army is extremely slow.
Just like the mixed infantry and cavalry legion, why the marching speed is the same as that of the infantry? To put it bluntly, it is to take care of the slowest part. What determines the fastest marching speed of a legion is not the fastest legion, but the slowest legion.
If you think about it this way, Sichuan and Shu are basically infantry, and the standard marching speed is not slow when all the soldiers are elite soldiers. The reason why it delays time is, to put it bluntly, it is the baggage train, and the longer the baggage train delays, the longer it takes.
The longer it is, the more food it needs, and the more food it has, the slower it will go.
It's simply a vicious cycle.
Zhang Song directly cut down the baggage train with a swipe of his pen. When the soldiers were all elite veterans, the speed was at least five times faster.
Okay, let's do that. Now we only need to think about how to live without the soldiers in the baggage team. This is not a problem at all for people like Zhang Song who have the mental talent to find divine teammates. The mental talent can be used three times a year.
Solve this problem and consume it once. The problem is solved. Don't stop the baggage team and directly set up a food storage point.
As long as each soldier carries no more than fifteen kilograms of dry food, which is seven days of food, it actually does not affect the marching speed. In other words, as long as each food storage point is no more than seven days of marching distance apart, the Shu army can achieve light disease.
preparation.
The remaining problem is the setting up of grain storage points. Anyway, Liu Zhang basically doesn't care. How to arrange the treasury is Zhang Song's own business. In this way, Zhang Song directly changed the distribution of treasury in Shu County and even started to concentrate on it.
The population of a major county ensures that the treasury is full of food.
Thanks to the Xiongnu invasion the year before last, the civil and military forces of Sichuan and Shu had to give an explanation to Liu Zhang and completely wipe out the southern part of Yizhou. The Southern Barbarians were also included in the rule, and social conflicts were alleviated a lot. Otherwise, no matter how good Zhang Song's plan was, there would be no success.
It is possible to implement it.
Liu Zhang was overjoyed when he heard this and ordered him to go down. Zhang Song said that I have finished handling it and you will wait and see the result of this situation.
"How long does it take to march to the southwest with this method?" Liu Zhang glanced at Zhang Song with great satisfaction, and then asked.
"Forty days, with General Yan's marching speed, we can arrive within forty days." Zhang Song said smoothly. He had already verified these things. For this reason, he emptied the Shu County treasury to
It was almost like a horse race, and then one city after another moved over.
But I guess Liu Zhang wouldn't care about these things. Even if he knew how Zhang Song did such a thing, he would probably pat Zhang Song on the shoulder and say, what a great job he did.
"In this case, General Yan, it's up to you. If the situation ahead is not good, send me a message and I will personally go to the southwest to supervise the battle." Liu Zhang pressed the hilt of the sword with one hand and looked at Yan Yan and said majestically.
Yan Yan nodded expressionlessly, and then gave Zhang Song a look. Zhang Song understood and said that he would definitely keep an eye on Liu Zhang and would not let Liu Zhang go to the front line. It was not that Zhang Song and Yan Yan looked down on Liu Zhang. To be honest, Liu Zhang would lead the way when he went to the front line.
, it can definitely boost morale, but the problem is that if you run to the front line, Yan Yan, Zhang Ren and others will definitely not be able to use it.
"Raise troops overnight!" Liu Zhang shouted, and then he personally picked up the drumsticks and beat the war drums on the city wall.
The dull marching drums, the subsequent sound of trumpets, and the sound of neat footsteps followed Yan Yan and others as they jumped off the city wall. In the darkness where the firelight failed to shine, a large number of people wearing black plate armor appeared.
The soldiers stepped out, followed by a uniform roar.
"Send troops!" With the sound of sending troops, Yan Yan reined in his horse with one hand, and the horse's hooves jumped into the air. Then he roared and rushed forward, and all the soldiers began to march with long strides.
At the same time, Zhang Song ordered all civil servants who were still on the inner city wall to work overtime temporarily to deal with the problems left behind after Yan Yan and others left.
Soon, on the wall of the inner city of Chengdu, except for a few guards standing guard, there were only two pairs of monarchs and ministers, Liu Zhang and Zhang Song, and Yuan Shu and Ji Ling.
"Yuan Gongli, how do you think of my brave men?" After watching all the soldiers in Chengdu City leave, Liu Zhang flicked his wide sleeves and looked at Yuan Shu, who was holding his arms with a hint of arrogance.
Night walking in brocade clothes was not Liu Zhang's hobby. He just liked to show off to others, especially guys like Yuan Shu who were on the same level as him.
Yuan Shu looked at the black-armored army that had disappeared at the city gate. Even though he had experienced wars and had led a strong army, he had to admit that the magnanimity and strength that Liu Zhang had shown before could be considered to be on the stage and placed in front of him.
Being called the dominant player in recent years is not a problem.
"Hmph, a guy who doesn't have 400,000 soldiers actually asks me such a question!" Yuan Shu said with a sneer. You want to get his Yuan Shu's recognition. You think too much. I, Yuan Shu, just can't speak. If you don't accept it, you'll bite me."
The tiger is coming, let’s go!”
After saying that, Yuan Shu sneered, turned around and walked away. Although Yuan Shu was dissatisfied, looking at the situation, he felt that with Liu Zhang's performance, if the so-called 150,000 Guishuang army attacked the Han Dynasty, it would be more difficult for Guishuang to attack the Han Dynasty.
The result Shuang wants is strange.
"Bastard!" Liu Zhang originally looked arrogant and arrogant, but Yuan Shu went up and poured a basin of cold water on Liu Zhang, dousing him directly, so that Liu Zhang couldn't even speak. It took him a while to react, and he saw that he had been submerged in darkness.
Yuan Shu, who was among them, roared, "Bastard, Yuan Gongli, don't leave if you have the guts. I will teach you how to behave now. Stop him."
Zhang Song smiled bitterly and pulled Liu Zhang, "My lord, you can't be majestic for even a quarter of an hour."
After trying hard to convince Liu Zhang, Zhang Song felt inexplicably tired. A quarter of an hour ago, Liu Zhang was still holding a powerful army, stationed in the southwest, guarding one side, and the powerful Han clan clan. However, a quarter of an hour later, he wanted to make peace with him.
