After Li Jing handed over the responsibility of logistics security to Chen Fei, Chen Fei could only open his mobile phone to find information about logistics supply lines in later generations, after all, there are many materials to find in later generations. And these later generations of military strategists have undergone a lot of improvements and various additions, which are all very experienced. If it can be used in ancient warfare, then it is naturally the best.

"Vertical resupply? Side resupply? Pregnant! Chen Fei said.

Chen Fei quickly informed Li Jing that he had a good solution.

"General Li, in the past, our army used to use the method of vertical supply, which is very unfavorable to our army. We usually use the supply line and the army is a 'D' shape. The horizontal one is our army, and the vertical one is our supply line, and this situation is very unfavorable to our supply line. ”

"First of all, both sides of his supply line are exposed to the enemy, so that the enemy can attack from both sides, and cut off our supply line at any time. In this way, not only will we have to form another army to protect the supply line, but the supply route will be relatively long. If we are in this 'D' pattern, that is, we must transport all the materials to the army, and the material resources consumed are also increasing, and then the cost of transportation is very large, so we are not under great pressure on the supply line. ”

Li Jing took a look at the supply mode of this "D" character, which is also the so-called vertical supply, and the supply line and the army are in a vertical line. This method of supply is easy to be harassed and cut off by the enemy, and it is very dangerous to cut off the supply line. But Li Jing couldn't think of any way to solve it. This method of vertical supply has always been used in ancient times, so Li Jing doesn't think there is anything wrong with this method. That's how everyone uses it, so what's the problem?

"Do you have any good ideas?" Li Jing asked.

Chen Fei immediately said, "We might as well try the side supply!" ”

"Oh? Side replenishment. What does this mean? Li Jing asked.

Chen Fei immediately wrote a "two" on the paper, and then turned the paper ninety degrees to form a vertical "two".

"General Li, look at this 'two', if I put him upright, it will be two lines. The long line can be compared to our army, and the short line can be compared to the supply line. Here's how to do it. Our supply is actually parallel to the army, so there are many benefits. ”

"First of all, our security, our main army can be responsible for helping our supply lines to maintain security. Look. The long line here is the main army, so if the enemy wants to attack our supply line from this direction, it will inevitably pass through our main army. But they will inevitably not be able to conquer the main army, once the main army is overcome. There is no need for the supply lines to exist. In this way, one of the directions of our supply line can be said to be absolutely safe. Originally, we were going to defend in two directions. Now that we just need to defend in one direction, then the defensive pressure on our supply line is much lower. ”

"On the other hand, we can also reduce our transportation capacity by a lot. We can unload while transporting, so that we can unload at the bottom of the army, and then unload all the way, so that there are fewer and fewer things transported, so that we can gradually clean up. But in the old way, all the supplies had to be transported through the farthest distance. This not only lengthens the supply line, but also consumes a lot of capacity. As a result, the cost of replenishment is huge. ”

Chen Fei vividly explained to everyone the method of side supply, this kind of side supply is actually studied by later generations, which can protect the safety of supply materials on their side as much as possible, and can also make the materials achieve the maximum effect with the least capacity. And those generals were also surprised, they didn't expect that supplies could still play like this, this is really not simple. Originally, everyone didn't pay attention to the supplies, but they were able to play flowers in Chen Fei's hands, which made everyone feel that Chen Fei was still very capable.

"However, we have to adjust the direction of the attack! We were supposed to attack the Turks from a direct frontal attack, but if this flank supply was used, it would have to be changed to an oblique attack. Li Jing said.

However, Chen Fei said: "General Li, in fact, there is nothing wrong with this. The Turkic steppes are all plains, and there is no complicated geographical environment, so we can quickly sweep up from here. It doesn't matter if it's a direct frontal attack or an attack from the flanks, that's okay. As for the Turks, they can only be gradually squeezed into our living space, either they will go to Mobei, or they will submit to us from now on. However, I think the possibility that they can choose to go to Mobei is very low, after all, the weather is very cold now, and going to Mobei at this time is simply taking the initiative to find death. The Turks are very 'greedy for life and afraid of death', so I think they will choose to surrender. ”

Although this side supply needs to change the plan of the march, it does not change much for the overall strategic situation. Everyone's purpose is also to squeeze the living space of the Turks step by step, and then let the Turks either flee to the north of the desert, or submit to the Tang Dynasty. This time is the coldest time for the Turks in decades, and if they flee to Mobei at this time, I am afraid that the casualties will be very heavy. Once in Mobei, the cold weather was enough to make them miserable. So they only have one way, and that is to surrender to the Tang Dynasty, otherwise they will die.

And the change of this supply line did not affect Datang's plan, but was able to maintain Datang's supply security. So there are not too many problems for the military, so Datang can also solve this logistical problem.

"Pass the order, let the soldiers change their plans, and then change the army and the supply line to a 'two' shape, so that we can ensure the safety of the supply line!" Li Jing said.

Soon, the army immediately began to change its marching methods with Li Jing's order, and then began to prepare for changes step by step. The adjustment of the strategic march route this time can maintain the safety of the army's supply line, which can be said to make the Northern Expedition to the Turks more smooth.
