While the two of them walked towards the East Palace, Xia Hongsheng said to Li Chengqian: "Your Majesty, let you stay in Dingzhou to supervise the country, in my opinion, there are two purposes. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo”

"Which two purposes?" Li Chengqian asked.

"This is the first one...... It's for logistics. I told you, and you've experienced it yourself. Fighting a war is not only a matter of soldiers, but also a matter of strategy, but also logistics. No matter how desperate the soldiers are, no matter how shrewd their plans are, if the logistics are not good, they will all be in vain. Xia Hongsheng said to Li Chengqian as he walked: "The soldiers and horses have not moved, the grain and grass go first, and no matter how majestic the general is, he can't do anything without food." Since ancient times, due to problems with grain and grass, the enemy has cut off the grain route, and there have been countless cases of defeat. Therefore, in war, the issue of grain and grass must be given the highest priority, and it is useless to fight as many battles as there is as much grain and grass as there is. And, as I told you, logistics is not as simple as food. In addition to the food in this mouth, there are also those that are used in the hands, worn on the body, and stepped on under the feet...... The clothing, food, shelter, transportation, eating, drinking, and Lazar of all the soldiers can be said to be all logistics. When a large army fights, the food, drink and consumption required by hundreds of thousands of people is a huge number, and it is impossible for all of these things to move forward in tandem with the army. Therefore, it is particularly important for those who coordinate logistics in the rear. ”

While talking, the two had already arrived at the East Palace, Li Chengqian asked people to find their own clothes and give them to Xia Hongsheng, and then asked eagerly: "Brother Sheng, tell me about it while you change!" ”

Xia Hongsheng changed his clothes and said: "Let's take the previous dynasty as an example, the entire Sui Dynasty attacked Goguryeo four times without victory, and from a military point of view, poor logistics supply is the main reason. In the eighteenth year of the emperor's reign, the Han Dynasty led the Mabu army from Hebei to defeat Goguryeo. Later, when I came to Emperor Yang, Emperor Yang personally conquered Goguryeo in the eighth year of the Great Cause, and it was an unprecedented occasion at that time, and I think you have read it. "One hundred and thirty-three thousand eight hundred people", so many people, almost all of their grain and grass came from Liyang and Luokoucang, and then concentrated in Zhuojun through Caoyun; The armor staff is concentrated in Gaoyang. And the feeder doubles. What is that concept? It is as many as more than 2 million people who go to transport logistical supplies for the army at the front. The tragic scene caused by such large-scale labor is endless, and I won't say much to you. In the ninth year of the Great Cause, during the second expedition to Goguryeo, Yang Xuangan took advantage of the dissatisfaction of the grain transporters to set off a rebellion, which you just said. In the tenth year of the great cause, Emperor Yang attacked Goguryeo for the third time, and at that time the world was already in turmoil, and he did not return to the army, so he had to take Goguryeo to send Hu Sizheng to beg for a rough end. It can be said that the world of the former Sui was dragged down by the logistics required for the conquest of Goguryeo. ”

Li Chengqian nodded and said, "Yes, I just read about Yang Xuangan's change, so I feel that Chang'an should not be left empty." ”

Xia Hongsheng said with a smile: "The ministers of the DPRK and the Central Committee naturally have this kind of worry. Zheng Yuan, the assassin of the past, also went to the song, saying that Liaodong is far away, the grain transportation is difficult, and Dongyi is good at defending the city, and it cannot be attacked. The military financing and transportation of the conquest of Goguryeo were directly related to the stability of the current situation, so His Majesty could not but consider this issue in the first place. Hebei Province is the source of food and grass for the army on land. His Majesty took Tai Changqing Wei Ting as the feed envoy, and Cui Renshi, the servant of the Ministry of Civil Affairs, as his deputy, from all the states of Hebei to the degree of moderation, and listened to it cheaply. Wei Ting divided the labor to supervise Hebei Caoyun, and Cui Renshi divided labor to supervise Henan Caoyun. The grain and materials from all over the country will be concentrated in Youzhou by land and Cao, and Suyingzhou will be transported from Youzhou to the north, and Sugu Daren City will be stored in the east, and these two places will be used as the base for front-line logistics supply. ”

"Then according to this, if it is necessary for grain and grass logistics, I should also sit in Youzhou!" Li Chengqian asked rhetorically.

Xia Hongsheng shook his head with a smile and said, "Cheng Qian, if you are just a courtier, if you are for logistics, then you must go to Youzhou." But you're no ordinary courtier! Dingzhou, Zhongshan County in the Han Dynasty, Dingzhou in the Later Wei Dynasty, and Later Zhou and Sui Dynasty have been in it until now. It is also called Boling County, with the shoulders and backs of Zhenji, and the elbows and armpits of Youyan. Guanshan is dangerous, and the west is enough to face the Yun Dynasty. The river and land circulate, and the east can also be the sea. Its topography is also the Xiongjun County of Hebei. Although it is not as a place for grain and grass distribution like Youzhou, it is located in the hinterland of Hebei Province, and it is the hub of land transportation from the Central Plains to the northeast, and it is actually an important place for military supplies. Sitting in its place, you can supervise Hebei, remote control Henan, and go to Yongji Canal not far away, which can be said to be a key place to move the whole body. If there is a prince in charge, coupled with the assistance of Gao Shilian, Ma Zhou, Liu Bo Liu and other talents, it is enough to solve the worries. Cheng Qian, Your Majesty has done this, and handed over such an important place to you to sit as the governor, how can it not trust you?! ”

"It turns out that my father is thinking like this!" Li Chengqian listened to Xia Hongsheng's words, and was quite moved, and said: "I must do my part well and live up to my father's high expectations!" ”

Xia Hongsheng had already put on his clothes, and the two of them went back to Li Shimin, and while walking out, Xia Hongsheng said again: "Yes, Your Majesty does have high hopes for you. Let you sit in Dingzhou, in addition to supervising logistics matters, another reason is to deter and prevent Xue Yantuo. ”

"Xue Yantuo?" Li Chengqian was stunned for a moment, and then he was stunned again: "Brother Sheng, I understand!" The Tang Dynasty has now wiped out the Turks and Tuyuhun, and Xue Yantuo has become the strongest in the north. Goguryeo has always had communication with those people in the north, and often cited them as Austrian aid, hoping to become a horn to fight China, and this has always been the case since the Northern and Southern Dynasties to this day! Sheng, Xia and other prefectures have always been important towns to guard against Xue Yantuo, and the distance between them and Dingzhou is much smaller than the distance from Chang'an, and it is also closer to Liaodong. Moreover, Dingzhou can go straight to Mobei through the Flying Fox Road, in case Xue Yantuo is really variable, Dingzhou can directly command Shengzhou, Xiazhou and other places, and the army of Liao can also directly turn Dingzhou to Xue Yantuo! ”

Xia Hongsheng nodded: "That's right!" As for the other reason, it's purely for your sake. ”

"Oh?" Li Chengqian was stunned.

"As the crown prince, you have learned a lot of things for so many years, you have seen a lot of the world you should see, and you have heard a lot of things you should hear, Your Majesty has also cultivated you for so many years, you have to give an explanation to the courtiers, so that they feel that this prince is worthy of their continued assistance in the future, and will not disappoint the country they have built." Xia Hongsheng said: "Dingzhou is the key place after this expedition to Goguryeo, the former is the foundation of the army, and the latter is the foundation of the Tang Dynasty. In front of you, you have to lead the logistics of the army to ensure the smooth progress of the army. After that, you have to deal with national affairs, so that Datang is still in order and operating normally. This task is not unimportant, and it cannot be said that it is not arduous. If you can handle it properly, make a good impression on the courtiers. Then the courtiers will be more convincing to you. You can also make a name for yourself and prove your ability. Only in this way will you be able to convince the people without relying on your majesty's majesty, but on your own ability. (To be continued.) )
