The moon sank into the clouds for a while, and then revealed half of his face from the clouds, which made the road in front of the Chu army on the snowfield dim and bright. The light is not important, the important thing is that there is no snow for several days and the roads are solid. The 170,000-strong army lined up in a horizontal formation of more than fifteen miles, but the formation of each soldier marching was a column. As he walked, the Chu army, the Zhao army, and the Wei army opened up between their fronts.

According to the regulations of foot soldiers, the Chu army walked thirty-eight steps per minute, that is, seventy-six gui; Six feet is a step, each step is 1.35 meters. Each hour has 90 minutes, and the regulations stipulate that the march is 80 minutes followed by a 10-minute rest, that is, the march (if it is flat) is 4,104 meters per hour, which is 10.133 miles.

The step is the basis of all the tactical actions of the infantry, and the reason why the measurement system is different in various countries is mainly because of the different heights of the men in various countries after the rise of the infantry and the abandonment of the weekly system. The height is different, and the stride size is different. One step and six feet is customized, so the taller Zhao people are similar to the Qin people, one foot is about 23.1 centimeters, while the Chu ruler is only 22.5 centimeters, a difference of six millimeters.

The difference in each step is only 0.036 meters, but this is the most comfortable distance for a person to walk. People who are short and want to take big steps will have a lot of effort to walk; If the people are tall and the steps are short, it is not effortless, but the marching speed is too slow, so the ruler varies from country to country. This is also the reason why the height of the Chu army is less than seven feet and cannot be enlisted, the height is too short to walk long distances.

In the East, there is customization for each step, and the same is true in the West, which should be the general rule for infantry in the age of cold weapons. The Roman recruits described in the "Brief Art of War" were trained to walk in the army; Frederick himself prescribed that Prussian soldiers should take twenty-eight inch, or 0.73 meters, and seventy-five steps per minute, at the Napoleonic Statute of 1 August 1791 on the Training and Maneuvering of the Infantry, which also prescribed a cadence of two steps per step and seventy-six steps per minute.

Different armies have different pace lengths and cadences. The Chu army took thirty-eight steps per minute, and the Zhao army measured that as long as he was a trained soldier, his legs were used to walking at the same pace as the hour, whether he was training, fighting, marching, resting, ......, he maintained this pace and cadence - forty steps per minute.

For the same minute, the Chu army walked 51.3 meters, while the Zhao army walked 55.44 meters, a difference of 4.14 meters. The two armies were advancing side by side at this time, and the array would definitely have to be separated as they walked, and the gap in the front line came from this. If such a flaw is caught by the other party, it is likely to be a fatal injury.

This is also the reason why the soldiers who have been trained by the Qin army in Jiuying cannot integrate into the Chu army, their pace and cadence are different from those of the Chu army, the two are integrated into a formation, and the array is scattered as they walk. It is easy to write poems and it is difficult to change poems, and it is easy to change fists to preach boxing, it is difficult to change the use of a piece of material that has been set, and an old Yingshi pawn whose pace has been formed cannot be integrated into the Chu army array.

At this moment, the Chu army, the Zhao army, and the Wei army marched side by side towards Linzi, the Chu army rested for ten minutes every hour, and the Zhao and Wei armies had to rest for six more minutes, otherwise the distance between the two sides would become larger and larger (more than 300 meters per hour). Every time it was time to rest, the military officials rode across the whole line and rang the Duo bell, and when they heard the bell, the soldiers began to rest on the spot, and after resting, the Chu army went first for six minutes, and then the two armies of Zhao and Wei followed up, and the distance gradually narrowed and parallelized when the Duo bell rang again.

The whole army was advancing at the speed of the Chu army, and fifty-five li according to the marching plan drawn up by the shogunate would take six hours, with three quarters of an hour of food time in between. Departing at dusk, night eclipse, fixed dusk, midnight, rooster crowing, morning, dawn, scheduled to cross the Ziji Canal before dawn, and arrive at the north of Linzi City. After that, depending on the situation, the nail will eat, but it is more likely to eat the jerky in the arms.

When the Qin army beat the drum and gathered the generals, the Chu army happened to be resting and having a hot meal, and at this time the army had already walked thirty miles, and there were still twenty-six miles left from Linzi. The Qin army suddenly beat the drum and gathered the generals, and the cavalry immediately brought the news back. When Sima Shang heard the news, he said: "Qin Renjue! ”

"Throw away your armor and run away?" Xiong Jing immediately said that he did not give an order, and then looked at Sima Shang and Gongsun Mao.

The Chu army often walked thirty-eight steps per minute, fifty steps per minute, and a hundred steps per minute. The twenty-six-mile journey takes two and a half hours to walk in a regular way, and the long march is nearly two hours, and it does not take an hour to run. At this time, the coalition army was in a horizontal formation, and Xiong Jing was very worried that the two armies of Zhao and Wei would not be able to keep up, and if they couldn't keep up, it would be a flaw. At that time, the three armies will be in their own formations, repeating the mistakes of the Qin army in Niushoushui.

"Don't!" Sima Shang immediately shook his head when he heard this. He was familiar not only with the Qin army, but also with the Qi army. The Zhao army often wins against Qi, so Zhao will like to fight Qi. "The Qin people have already felt it, what is the Qi army?"

Xiong Jing was thinking about the coordination of the three armies of Chu, Zhao and Wei, and he forgot that the three armies of Chu, Zhao and Wei also had to coordinate with more than 200,000 Qi troops.

"Qi people are deceitful." Gongsun Mao interjected. "Since the Qin people have realized it, they are slow to form a formation and I am in a hurry, and I am not in a good position."

"What is good for bad at this time?" Sima Shang sighed, in fact, he didn't believe in Qi Ren, but now, what if he didn't believe it. With the Chu army here, the two armies of Zhao and Wei will not be completely annihilated. "Our army should quickly conspire with the Qi people to determine when to form a formation. The Qi army has elites, but there are many mediocre soldiers, although the strategists have a pre-drawing, I am afraid that they will not be able to do it, and at most they will form a battle. ”

"The Qin people have already felt that if it is ...... to the dawn," Xiong Jing had an impulse as he spoke. Impulsively ordered the Chu army to rush to Linzi and drag the Qin army, but this impulse was quickly dispelled by Fox Baby and others.

"I think it's the most Danming. Tomorrow is dark, how can our army fight? The fox baby asked. Dawn is between the dawn and the morning meal, to be exact, after the three quarters of the dawn. Tonight the night sky is cloudy and not clear, and once there is no moon, you can't see anything clearly.

The fox baby is like this, and Zhuang Wudi also said: "The minister thinks that it will be bright." Only after the dawn can fight, and the darkness cannot be warn. It is expected that Qi people should form a formation in Danming, and often march our army to the north of Linzi, and Danming will be arrayed. Just leave it the same. ”

When the military must obey the sky, Xiong Jing glanced up at the moon, and the moon seemed to be afraid of his angry gaze, so he quickly hid in the clouds, and the sky and the earth were dark. Seeing this scene, he nodded helplessly and said, "No change." After saying this, he was very unwilling, and then said: "If the Qin army wants to abandon the camp, the array will inevitably be chaotic." Hurry up and wait for the opportunity to attack! I also sent an order to all pawns, beware of the Qin army attacking me! ”

The advantage of the Chu army was that the Qin army did not know which direction it was in, and although the Qin army had more than 40,000 cavalry troops, it had to defend on three sides. Regardless of whether the Qin army went out of the camp or abandoned the camp and fled, the cavalry of the Chu army would give it a fierce blow.

Xiong Jing ordered, the soldiers quickly rushed to the west to give the order, when the Qi army scouts arrived, the sound of rumbling horses' hooves sounded in the west, and the cavalry led by Concubine Jing was taking advantage of the moonlight to quickly go west.
