After the distance was determined, the cavalrymen carried their rifle slings, stuck them on the ground in the direction of due east and west, and straightened them up in a row.

Thanks to the major military operation last night, 80,000 to 90,000 people had to be pulled together like a rope to form an array.

In the desperation at that time, we hastily found a way to mark the boundary with a gun rope. Unexpectedly, we now have to plan an ambush circle, and the gun rope has become a measuring tool.

Li Mengxi stood there, watching the cavalrymen busy, extending the gun rope from the middle to the east, almost reaching the large wasteland to the east, and to the west, another three to four hundred steps in length.

In total, it is an extremely long gun rope line with a total length of more than 700 steps.

If the seven hundred steps were filled with troops, Huangfusong formed a long and narrow pocket formation and ran from one end to the other, but Huangfusong was still surrounded.

Li Mengxi felt that the encirclement seemed too big. But if he wanted to encircle Huangfu Song from a distance without Huangfu Song noticing, this was the minimum encirclement range.

If there is only a single row of encirclement, even if the soldiers are one after another and holding hands, the encirclement can be tightly drawn up and tightly sealed.

However, I have seen soldiers practice offensive and defensive tactics. To be able to fight and resist the impact of enemy infantry and cavalry, the formation must have at least three rows of spears, and it must be a tight formation.

The line of a single platoon of soldiers seemed to be tight and solid, with no flaw in it, but it collapsed immediately.

Therefore, the ambushes must be at least strong enough to form a tight formation in three rows in front and behind.

In this way, the encirclement was already very large, and it not only surrounded one crossroads, but also had to leave a large number of troops deployed in the front. The troops that could be used to ambush the crossroads were only at most one-third of the rebel forces.

There is a dilemma, if we want to encircle tightly, the array will be weak.

If the formation is tight, at least even if the army's cavalry is charging, the three columns of spears can carry it. If such a solid formation is to be set up, the troops are limited and the encirclement cannot be tightly encircled.

Li Mengxi and Guan Yu discussed, "Maybe we should use the method of sparse formation? Make the square formations piece by piece and form a close array, but make the distance between the square formations and the two formations farther apart."

In this way, the formation can be solid and tightly enclosed, even if it is sparse, it will not be exposed."

"It's just," Li Mengxi frowned as he looked at the mark of the gun rope in the distance, "there are gaps between the phalanxes. If the gaps are not long, the encirclement will not be tight; but if the gaps are too long, it will be scattered.

also.

If the enemy army comes from between the two formations, our army cannot stop it."

Regarding Li Mengxi's question, Guan Yu pondered for a moment and soon came up with a solution, "It doesn't matter." Guan Yu said, pointing to the distance, and explained to Li Mengxi, "You can fill the gaps in the formation with your cavalry.

The conflict between one cavalry unit and ten cavalry units is as great as that of ten infantry units.

Among the two infantry formations, if the distance between the infantry formations is several formations wide and there are dozens of cavalry in the middle, it will be enough to guard the gap, enough to frighten the enemy, and enough to fight."

Li Mengxi suddenly understood and nodded.

Li Mengxi had an unexpected gain. He originally thought that guarding was the commander of the infantry, and defense was not a specialty of the cavalry. The cavalry should be good at attacking or making roundabout assaults.

However, due to its strong maneuverability and wide combat radius, if the cavalry is to attack and defend, the defensive area and the battlefield that the cavalry can defend with the same force is much larger than that of the infantry.

One hundred paces in length, the ten cavalrymen separated each other, each cavalry was intimidating for ten paces, and at a distance of ten paces, the cavalry could kill from one end to the other in a breath.

As for the infantry, the infantry must guard a hundred steps in length. If they spread out to defend, there will be only one person at a step, making them vulnerable.

It is possible for ten cavalry to defend a hundred paces in length for a long time, but it is extremely difficult for a hundred infantry to hold a hundred paces in length.

The infantry formations were rearranged into strong formations, lined up solidly, and gaps were created. The gaps were filled with cavalry, so that limited troops could be used to build a huge encirclement network that was both tight and solid enough.

The ambush array is ready.

Take a thousand-man team as one unit, and the thousand-man team forms three horizontal rows of gun formations. There is a huge gap between the gun formations and the gun formations. The gap is fifty paces wide. Ten cavalry are divided into a team and guarded by a single cavalry.

Five steps.

Then comes the meticulous planning process.

At the ambush line, the position of the infantry formation, the starting point of the infantry formation, and the position of the cavalry formation are marked in detail.

Because the ambush line is far away from the road and is not easily exposed, when leaving a mark, there is no need to look for trees as camouflage. Just follow the straight line drawn by the gun rope and dig pits along the straight line to mark the mark.

.

Markers are unified on the left and equally spaced apart.

Wherever the mark is, it is the starting point of the gun formation, not the end.

During Li Mengxi's inspection in the past, he discovered a small problem. If there is only one pit at the marking point of each queue, it seems that there is no way to line up the queues.

Because of the direction, there is no reference target in the wild. There is a pit on the ground. If we line up at the pit, then the queue will line up on the pit when facing south and north, and we will also line up on the pit when facing east and west.

The queue is not only a factor of position, but also direction.

Li Mengxi thought about it briefly and came up with a perfect solution.

When he ordered his soldiers to dig pits, they used a hoe to remove a layer of soil between the pits along a straight line to connect the pits.
