Since Gil Harang led the army back ten miles, the stone gate was temporarily calm.

Chief of Staff Sun Dingliao seized the opportunity to adjust the deployment, remove the wounded, replace them with new soldiers, strengthen the fortifications at the junction of the Dongshimen Fort and the Great Wall, repair the barricades that were damaged by the startled horses, and clean up the dead and wounded horses along the way.

The local people were very careful when cleaning up the dead horses. They first took off the harness, took off the horseshoe, cut off the horse's mane and tail, and carefully preserved it; Carefully plan the knife according to the wound of the horse, and strive to peel off the maximum area of the horse's skin; Remove the horse meat, and the remaining horse bones are dried or can be sold for money.

The hot weather can't hold the horse meat, and for a while, from the stone gate to the front of the stone gate, there is the smell of stewed meat.

This state of affairs lasted until the end of the day, when the relieved Manchurian soldiers began to attack Dongshimen Mountain again.

Yang Liulang, who was in charge of defending East Shimen Mountain, felt very strange.

The Manchurian soldiers were not as crazy as they were yesterday.

Under the long-distance bombardment of the red-coated artillery, the Manchurian soldiers organized several charges as if they were pretending, and as soon as the battery counterattacked, the Manchurian soldiers immediately withdrew far away.

gave Yang Liulang the feeling that the Manchurian soldiers were insincere in attacking the Dongshimen Fort.

Yang Liulang told the chief of staff through the walkie-talkie, and Sun Dingliao was not sure what the Manchurian soldiers wanted to do.

It stands to reason that horses are a kind of impatient livestock, and after such a wild run last night, the Manchurian soldiers should let the horses rest for two days before they can make big moves. Perhaps the Manchurian soldiers are simply absent-minded when they hit the Dongshimen Fort now.

In the evening, the local people rushed to report that the locals who had gone into the mountains to "pick up bargains" had found a large number of Manchurian soldiers marching west in a tributary valley on the west side of the Shimen Waterway.

Sun Dingliao hurriedly summoned Guo Shimason, Wen Muzuo and several other locals to come over to understand the terrain.

Several people said that this valley road is a dead end, and if you want to move forward after reaching the end, you can only climb the mountain.

But once you cross the mountain, you can go down to the golden ditch twenty miles away on the west side of the Shimen Waterway.

Sun Dingliao was suddenly shocked into a cold sweat.

Because although the south side of the Golden Ditch is flat, the north side is almost impassable, and it is extremely unlikely that the Manchurian soldiers will take the Golden Ditch. The coalition forces were limited, and Sun Dingliao gave up on arming in Jingou at the beginning. It can be said that the only strength of the coalition army in Jingou is the dozens of Tumut defenders in the ancient barrier city of Nankouzi in Jingou.

Because I don't know when the Manchurian soldiers set off, I didn't estimate when the Manchurian soldiers would arrive at Jingou.

The military situation is urgent, and the chief of staff now has almost no troops to send!

Accounting to calculate, Sun Dingliao squeezed out part of the troops of Shimen Barrier City, led by Kong Youxing and Niu Li'er, and immediately went out of Shimen and rode along the foot of Qingshan Mountain to aid Jingou, and then Wen Muzuo led a part of the people to arrive on foot.

Sun Dingliao was very anxious in his heart, why didn't the third battalion that he said he should have arrived yesterday still arrived?

……

In addition, Sun Yi and Yang Ritian led three battalions to reinforce Jiuyuan, and arrived at Zhaojun's tomb in the evening after a day and a night of drifting on the Yellow River.

The allied waterjet armored ships, as they are called, are still reed rafts in the final analysis, with neither beds nor toilets. Sun Yi was so sick in the so-called cabin that his bones were sore, and as soon as he saw the riverbed on both sides turned to stone, he immediately ordered the whole army to stop the ship and dock.

This is a natural ferry, because in ancient times, Jinjin originated in the golden ditch and joined the Yellow River here, so the name is Jinjindu.

The people who moved west on the north bank of Jinjindu were in an endless stream, and they stopped to watch when they saw a large army coming to help. When they learned that it was Tabu Nang who led the troops to recruit in person, they offered the best goat's milk to eat.

Jia Daoshi, the military advisor who went ashore, pointed to the mound on the south bank and told the soldiers the story of Zhaojun's exit, and Bu Shijiu seriously interrupted Jia's story to ask for advice: "There are no less than a dozen places on this grassland known as Zhaojun's tomb and Zhaojun's tomb, do you know which one is true?" ”

Jia Daoshi was speechless.

Sun Yi relieved the siege of Jia Daoshi: "It doesn't matter which one is true, the important thing is why there are so many places on the grassland that claim to be the tomb of Zhaojun?" ”

Jia Junshi stroked the feather fan, "Ah! People have fixed their minds that this has been the case inside and outside the Great Wall since ancient times. Now the people of Jinguo are eating pot pulp, precisely because our army is the benevolent and righteous teacher who saves the people from fire and water and relieves the people from hanging upside down. ”

The captain of the communication corps, the orphan boss Wang Changsheng, hurriedly came to Sun Yi with the radio.

Sun Yi's portable shortwave radio has an electronic barometer, and Sun Yi has already instructed the boss to turn on the computer regularly to record the air pressure, in order to grasp the arrival of the rainy season in advance.

The first thing the boss did when he went ashore was to turn on the radio, but he didn't expect that there was a conversation between Sun Dingliao and Yang Liulang on the radio, and the content was that a team of Manchurian soldiers was going to go over the mountains to Jingou, and the two were urgently mobilizing troops. The boss interjected into the conversation, but the two of them didn't seem to hear at all.

Sun Yi glanced at the green mountains dozens of miles to the north, and sighed that he finally realized the benefits of a copycat machine.

Practice has proved many times that the transmitting power of the two copycat walkie-talkies that Sun Yi bought online not only exceeds the standard, but also seriously exceeds the standard.

Now the location of the two walkie-talkies is on the mountain, and their signals can be transmitted to the radio station in Jinjindu, but the signal of the radio station in Jinjindu cannot be transmitted to the walkie-talkie on the mountain.

Sun Yi immediately decided that the three battalions would abandon the boat and land here, and he and Yang Ritian would lead the direct reinforcement of Jingou.

The current three battalions are very different from the previous three battalions.

After experiencing several battles, Sun Yi slowly gained some experience, and he felt that one of the major characteristics of the Ming Dynasty's troops was the slow marching speed.

The Ming army basically traveled 30 miles a day, and the Manchurian army could travel up to 50 miles a day, and this slow speed of movement made the army's movements without suddenness and secrecy at all.

In later generations, the ordinary marching speed of the communist army was more than 5 kilometers per hour, and the daily march could reach 50 or 60 kilometers, and the main tactic was to fight behind enemy lines.

In the 80s, the standard of the infantry test of the Nationalist Army was to pass a march of 50 kilometers a day in full armor, a daily 70 km march in full armor, and a pass of 100 kilometers every 24 hours for a forced march in full armor.

They are all of the same race, why is there such a big difference?

After the analysis, Sun Yi concluded that the problem was not people.

Later generations may have better physical strength, but the people of the Ming Dynasty were more able to endure hardships, and the two can be completely offset.

The problem lies in the logistics of the army.

Regardless of the Ming army or the Manchu army, the materials that must be carried when going out on the expedition are weapons, armor, camp tents, grain and grass. Depending on the class, you may also need to carry additional horses, tinkerers, artillery, and so on.

A pair of cotton armor in the Ming Dynasty weighed fifty or sixty catties, and the daily consumption of two catties of grain by the soldiers was calculated, and ten days was twenty catties, plus weapons and basic survival materials, and a soldier's entourage was at least 100 catties.

The transportation of these materials can only be done with the help of livestock, and the daily consumption of an ordinary horse is "a bunch of grass, three liters of beans", and the weight is calculated as fifteen catties of grass fodder and two catties of concentrate fodder per day.

If all the horse's feed is carried, ten days is one hundred and seventy pounds, which means that another horse is needed, and this other horse needs another hundred and seventy pounds of feed......

Therefore, the grass for the horses depends on grazing on the spot, in other words, first, the horses must be given a lot of grazing time in addition to the daily march, and second, the army must march in the season and terrain where there is grass. In addition, the horses marched for days and days and had a great physical exertion, so they had to be allowed to recuperate after several days of continuous marching.

In later generations, the standard used by troops in various countries was that the weight of a single soldier should not exceed one-third of his body weight, and under this weight standard, a single soldier could march continuously at a speed of 50 kilometers a day on foot, and forcibly march 100 kilometers a day. Converted into the distance of the Ming Dynasty, it is 86 miles a day for continuous marching, and 170 miles for a day to forcibly march.

So in fact, it was not people, but the accompanying baggage of the Ming Dynasty army that slowed down the speed of the march.

In the later generations of the Second World War, the old Japanese army taught the marching speed as an example, and the standard of the combined forces of the various military departments was 24 kilometers per day, that is, 40 miles per day, which was actually not much stronger than the Manchurian soldiers.

In order to improve the mobility of the army, Sun Yi had to reduce the baggage of his entourage, and it was best to be able to carry all the baggage on the shoulders of the soldiers, as in later generations.

Sun Yide was able to bring this idea to fruition thanks to the electric three-eyed gun and composite fiber armor.

The use of electric three-eyed guns reduced the chances of hand-to-hand combat, making the soldier's heavy armor unnecessary; The combined composite fiber helmets and short chest armor of the coalition army were no more than 20 catties, making it possible for the coalition army to carry all the supplies on the back of the soldiers.

Because it was summer to sleep in the open, Sun Yi simply cut down the tents of the three battalions; In fact, the coalition forces did not have so many tents either.

The food regulations for the soldiers of the three battalions were that each person carried ten catties of dry food, one catty of milk lumps, one water bladder and one small packet of water purification pills.

The so-called water purification pill is a semi-finished product of explosives - sodium hypochlorite plus alum. Sodium hypochlorite is responsible for sterilization, alum is responsible for precipitation, the water purification effect is super good, and this formula is also used in field sports in later generations, but the taste of the purified water is indeed slightly unpleasant.

Coupled with the soldiers' weapons and weapons consumables, Sun Yi successfully controlled the maximum weight of ordinary soldiers in the third battalion to less than one-third of their body weight.

In this way, the third battalion can move and flexibly intersperse and fight a five- to six-day sports battle. If combined with the water transportation support of the Yellow River of the Water Division, the third battalion can be active on both sides of the Yellow River for two to three days.

In the 50s, the U.S. military had a more detailed presence: In general, marching troops had a 10-minute rest time every hour, and the speed of road marching was 4 kilometers per hour, and the speed of field marching was 2.5 kilometers per hour. The speed of the road march is 3 kilometers per hour at night and 1.6 kilometers per hour for the night field march. Under the state of forced march, the troops moved 56 kilometers in 24 hours, 100 kilometers in 48 hours, and 130 kilometers in 72 hours.

Since the weight of individual soldiers in the 50s was more than one-third of the weight of the soldiers, Sun Yiyi referred to the proportional relationship of the marching distance under various conditions in this teaching.

Sun Yi estimated that the three battalions after light equipment could guarantee fifty miles a day of ordinary marching under grassland road conditions. The forced march is because it requires night marching, and the soldiers suffer from night blindness too much, it is difficult to estimate at present, and it is hoped that it can reach a hundred miles.

If the third battalion can achieve this standard, Sun Yi will be very satisfied. Because at this time, everyone believed in Sun Tzu's Art of War: "If you fight for profit for a hundred miles, you will capture the general, and the strong one will come first, and the tired one will come later, and then eleven even." Fifty miles and fight for profit, then the general, the law is half to. Thirty miles and for profit, two-thirds to. ”

This means that a hundred-mile march can only reach one-tenth of the time on time, a fifty-mile march can only reach half of it on time, and a thirty-mile march can only reach two-thirds of the time.

In short, the generals of the Ming Dynasty generally believed that the rapid march of the army was a very risky thing and would not be adopted easily. If the third battalion could suddenly reach the enemy's eyes, it would definitely take these generals by surprise.

However, Sun Yi also paid a price for doing this, that is, the artillery of the third battalion had to be stripped away.

A tiger squat cannon weighs 100 catties, and a matching lead, gunpowder, and tiger squat bracket must be added; A general's cannon weighs 300 pounds, and in addition to lead and gunpowder, there are also necessary artillery carts and livestock.

Therefore, it was impossible for the artillery to keep up with the marching speed of the infantry of the three battalions, so Sun Yi separated all the artillery of the three battalions and organized them into a separate artillery team, and this time they acted with the naval division.

Now that it is almost dark, it is just right to test the effect of the night march of the three battalions.

Bu 19 led the fleet to continue the descent with the General Staff Department, the Second Staff Department, the Health Team and the Baggage, and Li Guang led the Third Battalion after a short rest and set off overnight along the dry Jinjin River.

Yang Ritian recruited some local horses, sent a rider to report to the chief of staff, a rider to report to Jingou Barrier City to prepare hot water, and handed over the rest to Sun Yi, Qiqige and himself and other generals to ride.

Sun Yi's guard captain Wang Sultan rode a mare and five foot guards at the front of the line.

The stuffy man carried a long wooden stick with an electric candle at the end, and the wire of the electric candle was connected to the battery on the horse's back.

The lit electric candles sizzled, illuminating a radius of dozens of feet on a moonless night.

- There's no way around it.

Hearing that Tabu Nang and Kikige were here, the people in the vicinity rushed to tell each other, and they all came to watch.

Sun Yi simply let everyone see enough.

Sun Yi taught Kikige to wave to the people on both sides from time to time, as he did.

When the people saw that the guards of Tabu Sang were holding a bright little sun, the small sun fell on the spark from time to time, leaving a puff of black smoke, and they all prostrated and kowtowed, and they did not dare to look directly.

Sun Yi's five guards were so tired that they ran back and forth to help the people up, and explained to the people that the kowtow had been abolished. Tabu Sang and Kikige look at it casually, one is not illegal, and the other is not money.
