Zhao Yu didn't know much about horses in his previous life, because he had rarely been in contact with real horses in that era, which also made his more understanding of horses come from books and film and television dramas, which inevitably have exaggerated elements, so that he and Wang Yinglin in front of him do not understand the real ability of horses, but have more blind faith in the descriptions of horses full of imagination and feelings of their ancestors, so that the world has illusions about war horses.

Therefore, when Zhao Yu heard that a horse ran to death at the sports meeting, the degree of surprise can be imagined, and it also gave him the idea of having an in-depth understanding of war horses. This is really not known, and when I check it, I was shocked, and the myth of the war horse traveling thousands of miles every day was shattered. And these have also become his magic weapon for winning all battles in the Tieba debate, and the data he cited also came from real examples in the past, which stunned those war horses 'Xiaobai'.

How fast can a cavalry run? In fact, if you lose your armor, you can march very quickly. Zhao Yu once found an extreme example, the flying general in the First Sino-Japanese War - Ye Zhichao. It is about 250 kilometers from Pyongyang to Dandong, and it is said that it can run in only one day and night, which is more powerful than the legendary whirlwind general, and can be said to have turned like a tornado. In this process, Ye Zhi was naturally on horseback, but even then it was far beyond the normal cavalry travel speed. It is conceivable that in order to save his life, Ye Zhichao does not know how many war horses he has killed, but it is appropriate to award him the title of 'Horse Slaughter'!

Of course, the above examples are somewhat extreme, and most of them are rumors of the time, so we should not believe them all. The modern and accurately recorded cavalry march record consulted by Zhao Yu was created by the famous Soviet general Budyonny, who pursued and killed the White Army for 1,100 kilometers in 40 days, which is called a miracle, but even then it is only about 25 kilometers per day. Of course, there are also factors such as the different types of war horses used by the Soviet army and Ye Zhichao's horses, and the endurance of Mongolian horses is better.

Even so, modern scientific calculations show that Mongolian horses can only travel 60 kilometers in eight hours, but this sport is called horse walking. If you use a running one, it will inevitably be a dead horse. However, this also proves a certain possibility, if you are prepared to ride three horses on wheels, it is possible to exceed the limit of 60 kilometers a day. Although the horse that runs with it will also consume physical strength, it is much better than a weight-bearing horse, and after sixty kilometers, leave the tired horse behind, change the horse to continue running, and carry it for a while, but this distance should not be too far, otherwise the horse will definitely be tired.

Zhao Yu thought that these were modern things, and the ancient prevailing conditions were not as good as those of modern times, and consulted the relevant data of ancient times. It was discovered that Xiahou Yuan recorded in the history books during the Three Kingdoms period had the reputation of "five hundred in three days, one thousand in six days" in Cao's army. In the Han Dynasty, one mile is more than 400 meters today, so his three-day march is more than 200 kilometers in modern times, but in fact it is only less than 70 kilometers per day.

Zhao Hao felt that with this record, the Mongolian cavalry would not exceed too much, because the probability of continuing to get out of the matter was very high, you must know that the war horse was a more precious property than a person at that time. In the Gulf War, the US military raced 260 kilometers in 89 hours, and defeated the Iraqi army with a modern command system like lightning, and its speed was only 70 kilometers a day!

One can imagine how shocked and chaotic it would be when it was hit by such a blow at the communication speed of the ancient army. Liu Bang was the biggest victim of this, he was beaten by Xiang Yu's blitz with 560,000 against 30,000 cavalry in Pengcheng, and even his children were thrown out of the car. Therefore, Zhao Hao thought that the marching speed of the ancient cavalry was actually about sixty kilometers, of course, this is still light cavalry, if it is a heavy cavalry in armor, then the horse can never be ridden in the march, and the speed of walking is basically the same. The march in actual combat was even slower by half, and a famous general like Budyonny could walk less than 30 kilometers a day, and if he went farther, he would have to overdraw his horsepower.

Whether the infantry could keep up with the cavalry was a controversial topic, but in ancient times it was an uncontroversial one. The cavalry has six legs, but you only have two legs, and fools know that the infantry will not be able to outrun the cavalry. In fact, Zhao Yu knew that it was not uncommon in modern warfare, and the Red First Army flew to capture the Luding Bridge for 25 hours and marched 240 miles.

If this is still a record of a one-day and one-night rapid march, then the four-day pursuit of Du Yuming in the Huaihai Battle in the War of Liberation can be called the limit, and he did not run away in a car. The People's Liberation Army (PLA) has to travel 300 kilometers in four days, and even if it marches in a straight line, it has to walk more than 70 kilometers a day. Even on a longer march, the Red Army marched an average of 37 kilometers a day, surpassing Budyonny's record.

Therefore, whether it is more endurance or than running, the PLA infantry has surpassed the average level of cavalry, and has repeatedly set the most fierce marching records in history. The conclusion is that in nature, horses must be faster than people. In the history of warfare since modern times, cavalry has also been faster than infantry in most cases, but there is no particularly obvious advantage between the two and the middle.

After Zhao Yu arrived in this era, he faced not only the problem of lack of horses, but also the problem of insufficient troops. When he went to Qiongzhou, he combined modern experience to train troops, so that the infantry could quickly maneuver on the island to make up for the shortage of troops. However, it was found that it was difficult to replicate in fact, because the infantry army with cold weapons as the main equipment had to maintain a strict formation when marching, and also considered preserving the physical strength of the soldiers for combat, so the general marching speed was limited to 30 miles a day.

Obviously, in the era of cold weapons, horses still ran faster than people, but not much, especially when marching in large armies, there were no Mongolians

Cavalry is several times more mobile than the ancient infantry. Because the cavalry also had to take into account the problem of physical strength, when the cavalry was put into the battlefield, it was mainly a shock battle, so it was necessary to maintain the physical strength of the sprint, if the forced pursuit was carried out regardless of the horsepower, even if it reached the battlefield, it was meaningless.

Zhao Yu felt that Cao Cao's army chased Liu Bei back then, and was killed by Zhao Yun seven in and seven out at Changban Slope, and was blocked by Zhang Fei's more than 20 horsemen on the Dangyang Bridge and did not dare to pass, because Cao's 5,000 cavalry raced 300 miles in one day and one night. Thinking that Cao Jun's horsepower has been exhausted, seeing that the enemy army is in front, but he can't catch up, can't run, and can't fight, it is not strange to end up like this, but it has fulfilled the courage of Zhao Yun and Zhang Fei.

But now Zhao Yu is full of confidence that the Great Song Infantry Army can compete with the Mengyuan cavalry in terms of speed at the moment, and its confidence comes from their own changes. At present, the main infantry of the Song Forbidden Army was fully equipped with muskets, abandoned heavy armor and cold weapons, and reduced their burden, coupled with strict training and good food, so that their personal physical fitness was guaranteed.

More importantly, the use of firearms allows the battlefield output to no longer rely solely on the physical strength of soldiers, so that they can allocate more physical strength to the march. It is guaranteed that during the long march of forty miles a day, the combat effectiveness will not be reduced. It can reach the speed of 100 miles a day in an emergency with a rapid march, of course, this speed cannot be maintained for a long time. Although it is still inferior to the cavalry, the gap is not so big.

The army of the Mengyuan army stationed in the Central Plains has given up its nomadic life and turned to maintain its existence in the form of tuntian, which will inevitably rely more on logistics supplies, but the consumption of cavalry is far greater than that of infantry, and when logistics is poor, it will fall behind the infantry. The reason is simple, horses have a strong load-bearing capacity and are equally expensive.

According to estimates, the food consumed by a war horse is almost equivalent to the amount of ten people. A person can carry a ten-day ration on his back, and according to the daily consumption of two liters, the weight is about twenty-two catties, which is completely bearable. And it is already very hard for the war horse to carry a person, and it is impossible to march with more than 200 catties of grain, even if there is forage replenishment on the way, it is necessary to eat food to ensure the physical strength of the war horse.

Some people will say that the Mongol soldiers also have two or three auxiliary horses to share the burden, but do not forget that the auxiliary horses also have to eat, and they also have to carry their share of grain and grass. Of course, if there is a complete logistical supply and a reliable baggage team at the front, it is still possible to ensure a high marching speed. At present, in order to increase the speed of the march to achieve the effect of surprise attack, Timur can rely on garrisons and prefectures along the way to replenish the territory.

However, 100,000 soldiers were fed by horses and horses, which was a huge number, which was an extremely heavy burden for each state and county, which forced Yuxi Timur to detour through Tongzhou to reduce the burden of logistics and supplies, and also had to carry some grain and grass to ensure the need to enter the Song Dynasty, and to capture a state and county with more grain reserves to obtain supplies to ensure the needs of subsequent operations. And this will inevitably slow down their marching speed, and it will also give Zhao Yu the time needed to dispatch his troops......

"So Your Majesty has decided to transfer part of the besieging army back to Jiangnan to participate in the battle to encircle and annihilate the enemy who invaded the south?" Wang Yinglin finally understood the meaning of what he had just said, and took a sip of wine before frowning.

"Well, Governor Wang also knows that the development of the situation has exceeded the estimate, and only by ensuring that after the enemy invaded the south is completely annihilated, can he consider recovering Lianghuai, otherwise everything is nonsense. Therefore, the siege and annihilation of Yuxi Timur's department is the first priority, but the only force that can be mobilized is our besieging army. Zhao Yu nodded.

"Then how many people is Your Majesty going to send back?" Wang Yinglin thought about it, he couldn't wipe out the enemy who invaded the south, everything was in vain, and he pondered for a moment and asked.

"I intend to return with half of my troops, leaving only the First Army and the Imperial Protector's Guards, as well as the First Brigade and the Baggage Brigade under my command, to continue the siege. The two divisions of the Second Army were all planned, and the 4th and 5th Brigades of the Imperial Front Protector Army, the Changzhou Army, the Jiangzhou Army, and the Runzhou Army were all transferred back to Jiangnan to participate in the encirclement and annihilation operations! Zhao Hao took a bite of the side dish and said indifferently.

"Your Majesty, no!" When Wang Yinglin heard this, he shook his head again and again. As His Majesty said, far more than half of the troops were recalled, and the little emperor still wanted to leave the siege behind, which could not be accepted by him in any way.

"Why not?" Zhao Hao smiled.

"Your Majesty, "The Art of War" says: "Ten are to surround it, five to attack it, and to fight it twice." "Although Wang Yinglin doesn't know how to use soldiers, he has read military books," according to this calculation, there are no less than 30,000 soldiers available in Yangzhou City, and after some of our army's southern transfer, there are barely 40,000, which is far inferior to Sun Tzu's teachings. In addition, His Majesty left this personal commander to besiege the city, in case the enemy in the city learned of the battle, or risked death to break through the siege, would not fall into danger for His Majesty. ”

"Sun Tzu's words are right, even if we call back most of our troops, we still can't form a tenfold advantage over the enemy who invaded the south, so I still have a lot of troops left to besiege the city!" Zhao Yu nodded thoughtfully.

"This ...... That's not what the minister meant! Wang Yinglin didn't expect that the little emperor would use his own words to block himself, and he was worried that His Majesty would misunderstand, so he waved his hand again and again.

"I know!" Zhao Yu looked at his anxious white face, and said with a smile, "Governor Wang is worried about my safety, but you must also know that the siege and annihilation of Yuxi Timur is not a siege, the combat area is large, and the enemy army is mostly cavalry, with strong mobility ability, and it is fighting in the enemy territory, so there is not much to consider." This forces us to block the main road with more troops, and the slightest negligence will allow the enemy to break through the encirclement, so that our long-planned plan will fall through, and it will also shake Jiangnan, so we must mobilize troops as much as possible to block the way to it, force it into the battlefield we have set, and surround it with regiments. ”

"But once ......!" Wang Yinglin became more and more anxious when he heard this, but he didn't know how to convince the little emperor.

"Governor Wang can rest assured that I will not be so stupid, and send troops back to help the enemy find out. Now Timur can hide his traces from the sky and the sea, and I can also set up suspicious soldiers, so that the enemy cannot know that the army has left. Zhao Hao smiled and drank a glass of wine.

"The minister thought that His Majesty should return to Jiangnan with the army. First, the end of the year is approaching, and the governors of various places will enter the capital and face the saints, and His Majesty needs to deal with them one by one; The two queens and several mothers are about to give birth, and they also need to be guarded by His Majesty; The matter of recovering the two Huai still needs to be discussed and planned by His Majesty and the important ministers, and a decision is made. Wang Yinglin was silent for a moment and persuaded again.

"I can't go, if I move the camp, I will be discovered by the enemy, this is one; If the enemy finds out that our army is retreating, but they find that I am still staying here, and they do not dare to break through without permission, this is the second; Moreover, the timing of the withdrawal is not easy to grasp, which is related to the success or failure of the war, and I cannot pretend to others. As for the affairs in Beijing, the Queen Mother and Lu Xiang are in charge, and it doesn't matter whether I return or not. And to discuss the matter of recovering the two Huai, he can only bother Governor Wang to go back. Zhao Yu heard him talk about how several wives were going to give birth to children, and he still hesitated for a moment, knowing that in ancient times when medicine was not developed, even if there were many imperial doctors to take care of it, it was still a very dangerous thing, but he suppressed his desire to witness the birth of the child with his own eyes.

"Your Majesty, the minister has the heavy responsibility of following the hu, how can he leave without permission!" When Wang Yinglin heard this, he was anxious and resolutely refused......
