Temporarily press how the protagonist opens the civilian education of modern schools, the protagonist travels through the darkest period of the Sichuan Massacre of mankind, which is an out-and-out troubled era, while opening the key to modernization, the most urgent thing is to survive and develop.

After hearing that Zhang Dingguo led his troops to retreat, after several admonitions, Wang Zhibang, who knew that the Great Western Army was gone, decided to return to the Shun Volunteers.

Considering that Zhang Xianzhong died in the battle of Xichong Phoenix Mountain in the north in history, it is speculated that Zhang Xianzhong may personally lead a large army to attack Shunqing City, appoint Wang Zhibang as a senior staff officer, and ask him to introduce the internal situation of the Great Western Army and the characteristics of marching and fighting every once in a while, and compile the "Guerrilla Operations Outline" as a teaching material for the students to study.

In addition, what we are most concerned about now is the formation of the troops, that is, external operations.

As everyone analyzed, after thwarting the Great Western Army's invasion of Shunqing Fucheng, facing the direct sharp reduction of the Great Western Army, in the future, it will be more likely to leave the base area and fight from a long distance.

War is essentially a contest between the two sides in terms of money and food, and in the ancient era when there were no trains, automobiles, and freighters, it was difficult for everyone to move forward, and it can be said that long-distance conquest was a nightmare for mankind.

As the saying goes, people are iron and rice are steel, and if you don't eat for three days, you will be hungry and panic. And when you fight, you fight with money and food.

The ancients often said that the emperor did not send hungry soldiers, and the army would be scattered if there was no food. The soldiers and horses have not moved, and the grain and grass go first, so it can be seen that the importance of grain and grass is seen.

The ancient army ate very poorly, and it has been verified that before the Song Dynasty, the army rarely had iron pots, most of them were pottery, and the pottery could only cook rice, often adding a little wild vegetables, but not stir-frying.

Just cooking rice, everyone also ate very poorly. The Qin Dynasty stipulated that for high-intensity work, half a bucket of millet in the morning and one-third bucket in the evening, while without fighting, one-third bucket of millet in the morning and evening.

In this way, there is a saying that there is food in the food, and the soldiers are hungry.

And the best way to solve it is for the soldiers to carry food.

In the Han Dynasty, baked cakes began to appear, and during the Song Dynasty, the soldiers went out to fight and ordered the city to make dry food, hemp cakes, wine and other grains, and the soldiers carried hemp cakes, sauce cakes, hard pieces of salt, etc., becoming the so-called pot helmet cake army.

In the Ming Dynasty, the round cake was roasted over charcoal fire, and then a small hole was poked in the middle, and then strung with a rope as a compressed biscuit, and when eating, the rice was soaked in hot water, which was the instant noodles of the Ming Dynasty.

When marching and fighting, soldiers can carry ten catties of this dry food (as a five-day military ration) for short-term operations.

Even during the Korean War in the previous life, the Chinese army's military food habits have not changed, when the war was in full swing, Mr. Zhou called on the people to fry noodles for the army, burn baked cakes, and the US military believed that the volunteer army worship offensive, in addition to ammunition, also includes the supply of military food.

In the era of cold weapons, each soldier wore thick armor (more than 20 catties), carried five or six catties of quilts and five or six catties of clothes, carried ten catties of military rations, and carried weapons, so that each soldier carried a weight of fifty or sixty catties, plus a marching tent or something, the normal march was only thirty or forty miles a day.

In the musket unit, each soldier carried seven or eight pounds of iron on his chest, quilts and clothes, gunpowder, iron sand, lead, and arquebus, and ten pounds of military rations, as well as bird guns and thorns.

For long-distance combat ration transportation, "The Art of War" once said:

The rest of the plan, people bear six buckets of rice, the pawn brings five days of dry food, one pawn, one pawn, one can go for 18 days, six buckets of rice, two liters of food per day. The two of them ate it, and it was all over in 18 days. If you return, you can only go for nine days. That is, one person replenishes the other, and after eighteen days the food is cut off.

The two of them were paid and died, and they could go for twenty-six days; Rice is one stone and two buckets, three people eat, six liters a day, eight days, then one husband's burden has been exhausted, and six days' food will be repatriated. On the next eighteen, two people ate, and four liters of food a day. If it is returned, it can be advanced for thirteen days. On the first eight days, the solar eclipse was six liters. Five days later, the return trip will result in a four-liter eclipse of food. That is, three people to supplement one, and after twenty-six days, the food will be cut off.

Three people are paid and one is gone, and one can go for thirty-one days; Rice is one stone and eight buckets, the first six and a half days, four people eat, eight liters a day. minus one husband, and give four days' rations. On the seventeenth, three people ate, six liters a day. and subtracted one husband, and gave nine days' rations. On the next eighteen, two people ate, and four liters of food a day. If you plan to return, you can go forward for 16 days. In the first six and a half days, the solar eclipse is eight liters. On the seventh day, the eclipse is six liters, and on the eleventh day, the eclipse is four liters and food. If three people supplement one, thirty-one days without food.

"The Art of War" once said that three people can supplement one person's food, which is close to the limit, but this can also ensure that the food is safe for a month.

The last time the Liukou attacked Shunqing, they couldn't stand it after burning 20,000 loads of military rations, and finally retreated if they didn't conquer the city.

How to solve the transportation of grain and grass in ancient times?

In the past, when I read ancient books, I often said how many tens of thousands of troops were sent, in addition to the possibility of exaggeration, it was probably to count these grain transport troops, if three people supplemented one person, 100,000 troops, the real capable of fighting is only 25,000 people.

A simple wheelbarrow, during which the consumption of military rations is reduced, and how much labor is reduced.

Even so, the consumption of military rations and the levy of labor were reduced a lot, but Yang Lin still thought that the wheelbarrow transported too little grain, and if there were other tools to replace it, it would not help to increase the number of battalions of sergeants.

In the north, it is transported by wheelbarrows and horse-drawn carriages, while in the south of China, the rivers are crisscrossed and the waterways are staggered.

Some people have verified why the Hunan army was able to defeat the Taiping army, transport grain through the sailors, and establish a water grain road, so as to ensure the supply of grain and grass.

Considering that the imminent future wars will take place mainly in the south, it is very important to build a fleet in this way and ensure the long-distance transportation of grain and grass.

According to the plan, in the future, long-distance transportation will be carried out mainly through the fleet, using the superiority of the naval army to protect the transport ships to reach the front line, and not by plundering a large number of horse-drawn wagons, as in the north.

The southern water network is dense and the waterways are criss-crossed, and the grain can be transported to the front line within 100 miles through the fleet, so the infantry army only needs to realize the last 100 miles of grain and grass transportation.

The most important thing now is the use and development of short-distance transport vehicles.

The first thing that comes to mind is of course bicycles and tricycles, which are not only simple in structure, but also completely mechanically driven, and the protagonist is very familiar with their structure, so it should not be difficult to build.

But this bicycle and tricycle rely entirely on foot power, and it is really shocking to develop it at once, and after thinking about it, the protagonist still gives up this kind of thinking, which will take at least a few decades of transition and cannot be developed in the short term.

Such suitable means of short-distance land transport are wheelbarrows, two-wheeled rickshaws, two-wheeled carriages, and four-wheeled carriages.

The first is a wheelbarrow, because there is only one wheel, there is a person wheeled to push (one person in front of the mountain road, one person in the back pulls), the transportation volume is between 6 buckets - 1 quintal, very suitable for walking in the mountain road,

A wheelbarrow transports one stone of grain (about 150 catties in ancient times), one person is paid one person, and two people eat 4 liters a day, so that they can eat for 15 to 25 days.

Rickshaw carts have been around since ancient times, but unlike modern times, they are mostly pushed by one person in the back, and in the same way as a wheelbarrow, they can be pulled in front of them, or one person pulling another person on a mountain road.

The stability of the two-wheeled rickshaw is good (such as modern two-wheeled vehicles, the two wheels and the handlebar form a plane), the transportation volume reaches between 1 quintal - 1 quintal and 5 buckets, if one person pays one person, two people eat 4 liters per day, so that two people can eat for 25-37.5 days.

The two-wheeled carriage currently used is different from the military two-wheeled carriage that is the standard configuration of the Chinese army in World War II, because it uses wide wheels, unlike the rubber tires of World War I and World War II, each two-wheeled carriage can transport 3.5-6 loads of grain (that is, 250 kg to 450 kg of goods, and the National Army in World War II uses rubber tires, and each two-wheeled carriage can transport 300-500 kg. ）

Unicycles, rickshaws, and horse-drawn carriages are not much different from modern vehicles, and if you really want to talk about the gap, the biggest gap is the wide wooden wheel, which is larger than rubber tire vehicles and has less transportation.

Among them, the most anticipated, or the most disappointing, four-wheeled carriages, because there is no steering device, the folk four-wheeled carriages are rarely used, and it is very inconvenient.

Carefully analyzed, the main thing is that the four tires are ancient on the body, and not by steering autocracy, as in the carriage.

Based on the analysis of unicycles, rickshaws, horse-drawn carriages, and four-wheeled vehicles, it was decided to develop new vehicles in the future on the basis of retaining unicycles, rickshaws, and horse-drawn carriages.

After the land transportation is solved, the transportation is relatively simple.

Although it is not a highway like modern times, asphalt roads, and ordinary roads extend in all directions, this era also has its own highways.

Since the end of the Han Dynasty, although the cart and two-wheeled carriage have been promoted on a large scale, there are not many horses and cattle among the Han people, and the main means of transportation is the wheelbarrow.

Since the Warring States Period, in order to strengthen local control, the country has established a number of roads such as Bao Chuan Road, Jinniu Road, Micang Road, Wuguan Road, so the road, the road is about four or five meters wide, and the road is all rammed and compacted, which is convenient for personnel to pass, which can be said to be an ancient highway.

In the Ming Dynasty, Hongwu Emperor Zhu Yuanzhang was worthy of being a farmer's son, a monk from Youfang, and when he was in power, although China was built into a small peasant economy and society, but the road construction was still solid.

The imperial court and local governments levied laborers to strengthen these military and economic arteries, and in some places even paved with stones to facilitate the passage of large vehicles.

Even if it is not between these traffic arteries, there are large roads connecting the counties, which are roughly equivalent to the asphalt roads of the previous life, and ordinary roads, ordinary carts, horse-drawn carriages, and wheelbarrows can still pass freely.

In lamenting the industrious wisdom of the ancients, lamenting that the ancient engineering has been durable for hundreds of years (the ancients may have limited product variety, but practicality, durability is quite strong, when I was a child, my father once said that a pair of rubber shoes in the past few years will not be broken, unlike after the reform and opening up, basically bought every year, broken every year), Yang Lin is full of reverie.

If a tool can be made to replace the ancient wheelbarrow to transport grain, this can not only ensure military needs, reduce logistics personnel, but also increase the mobility of troops.

There is no doubt that bicycles and tricycles are the first choice, and those who have never played with bicycles and tricycles in their previous lives are completely mechanically driven, with simple structures, and there is no obstacle to driving on this avenue, which is completely suitable for the environment at that time.

After pondering for a few days, considering that bicycles and tricycles were too shocking, they were not introduced.

But the use of two-wheeled carriages was not without problems, and the biggest problem in this era was the recruitment of horses and mules.

As mentioned earlier, in order to ensure the mobility of the army, the rogues plundered livestock everywhere they went, and because the demand was so great, they plundered not only horses, mules, but eventually even ploughing cattle.

Without animal power, just as there is no electricity in modern society, the level of farming has dropped sharply, and the whole society has returned to the era of slash-and-burn farming.

In the CD Plain, the core area ruled by the Great Western Army, due to the destruction of water conservancy and the loss of animal power, the cultivated area of local land was sharply reduced, and the CD Plain, the land of abundance, actually caused a famine.

Shunqing Prefecture in northern Sichuan has also been affected, in the first two months of the cultivation season, some people stopped animal power, but because the loss of animal power is too great, everyone is still complaining about the lack of animal power.

In order to solve the problem of animal power, many families often work as cattle workers, and everyone walks hard with farm tools on their shoulders like ploughing oxen, but even if it is so difficult, the area of cultivated land is very limited.

Although horses and mules were captured in the Battle of Shunqing, many of them had already been distributed to the displaced people who had been resettled, and after two months of collection, the mules and horses were less than half of what was needed, and it was impossible to complete the formation of the baggage transport troops.
