After sending Murong Fu away, Li Tong discussed the issue of army supply with his staff.

He sent a lot of materials to Heyuan this time, which was enough for the Heyuan army to maintain until the early autumn harvest. But the premise is that the Heyuan Army still follows the previous method of focusing on defense and ploughing and fighting. However, now that the overall strategy has changed, it is natural that there will be higher requirements for munitions.

Regardless of some unexpected situations, any war with clear operational objectives and complete overall planning is fought with logistics, including the Tibetan army, which has relatively low logistical requirements.

According to the ideas of Li Tong and Heiya Changzhi, the counterattack on Qinghai was mainly divided into three steps. The first step was naturally to seize control of Chiling and open up a channel for the army to attack Qinghai.

This process will last for about a month, and it is not easy for a Tibetan garrison in Chiling to be equally brave, and it is not easy to completely grasp the Chiling passage. Second, at present, it is the spring ploughing and farming is busy, and the main force of the Heyuan Army is defending at the eastern foot of Chiling, which can also ensure the safety of the cultivation environment and try to grab a batch of tuntian.

The second step is to preliminarily assemble the army through Chiling and sweep the Haidong region of Qinghai after occupying a certain advantage in Chiling.

In this step, the main force was about 20,000 people, mainly to use the Zhuhu vassals to participate in the war, spread out the battlefield as much as possible, scatter the troops, and destroy the various operations of Tibet in the Haidong region to the greatest extent. As for the time, it was chosen in early summer.

In early summer, Longbian warms up, and all the water enters the flood. The Tang Army chose to attack at this time, and it could also rely on a part of the water transportation profits, although it was not large, but it could also reduce some logistical pressure to some extent. Moreover, the climate at this time was pleasant, which was more conducive to the exertion of the combat effectiveness of the Tang Army.

On the other hand, due to the improvement of the aquatic and grass environment, all pastoral areas have entered the most important golden season of the year. Cattle and sheep need to be sheared, give birth, and return to animal power. Therefore, this season is similar to the autumn harvest in the farming season, and it is bound to be more difficult for the Tibetans to recruit herdsmen for war.

Therefore, the offensive during this period, even if it could not annihilate the Tibetan army, must also disrupt the rhythm of production in its pastoral areas and put the herdsmen around Qinghai in a difficult situation.

After the completion of the battle objectives at this time, the Tang army was to rely on Chiling, stationed in Haidong on the spot, and began to transport various construction materials to the Haidong area, and built the city along the periphery of Qinghai.

The third step of the war was chosen in early autumn, but it was not so much that they chose it, but that the opposite Tibetan side would definitely launch a counteroffensive at this time. The main task of the Tang army at this stage is to hold on to the Haidong region, as long as it can hold on to Haidong and consolidate the results of the war, then this battle can be said to be the victory of the Tang army.

Such a war plan also shows that although Li Tong and Heizhi Changzhi are not small, they also have to recognize a fact.

That is, after more than 30 years of occupation and digestion of Tuyuhun, Tubo has established its home advantage, and it is difficult to completely expel it from Tuyuhun after one or two wars.

Therefore, there is no need to madly establish slogans such as "Luo Shan Dao", a little simpler and realistic, Haidong Dao is already very satisfied, and even Chengfengling, Dafeichuan and other southern Qinghai regions dare not look in.

Of course, such a battle plan is not just wishful thinking, but a choice that is more conducive to the development of one's own strength in light of the real situation and mobilization mode of both sides.

Although all the people in Tibet are soldiers, they also pay attention to farming and animal husbandry at three times and military exercises at one time, and cannot be levied anytime and anywhere. Moreover, due to the insufficient output of the unit land itself, the number of people who can support it is also very limited, so except for a limited number of areas such as the royal capital Luosuchuan, there are not too many densely populated areas, and the period of mobilization and collection is very long.

Although the situation of Tuyuhun is slightly better than that of Tubo itself, it does not belong to the local forces of Tubo, and after so many years of heavy labor, suffering in the front and enjoying in the back, it is inevitable that there will be deep resentment, and the efficiency of expropriation and issuance is also not high.

Of course, considering the internal turmoil in the Tang Dynasty, Qinling had already had the idea of entering the army, and may have gathered a group of troops in advance.

This is also one of the reasons why the Heyuan Army did not dare to advance lightly, controlling Chiling, and dispatching scouts in the Haidong region in advance to watch the battlefield situation. In the face of an opponent like Qinling, there is no big mistake in being careful, the previous two big defeats were mainly lost in recklessness.

In this way, the time span of the whole war lasted for more than half a year, and it was necessary to take into account not only the subsequent increase in troops, but also the consumption of building a city in Haidong, and the investment in supplies was also massive.

Especially in the process of building a city in Haidong, if the Tibetan counterattack is too fierce and the tug-of-war is fierce, the consumption of the army will also surge. Therefore, according to the estimates of Li Tong and Heizhi Changzhi, the materials needed for this war should be increased by three to five times on the basis of the materials sent to Heyuan.

This number is really amazing, you must know that Li Tong spared no effort to support in order to ensure the safety of Longyou this time, and the prison guards in Shendu City and the harvest of raiding his house in Chang'an, one-third of the total amount was directly pulled to Longshang.

In other words, even if he emptied the savings of the entire Chang'an Shogunate now, it would be far from meeting the needs of this war. Therefore, it is not easy for Li Tong to make such a determination, but this is the price that Gaozong needs to pay for despising Tibet.

While thinking about it, Li Tong wrote and drew on the paper, listing several major material needs.

Liu Youqiu and the others only knew that His Royal Highness King Yong intended to attack Chiling, but they did not know the specific military plan, and when they saw the figures listed by His Royal Highness, they couldn't help but be dumbfounded. 2020

"There are 50,000 to 60,000 war horses, more than 100,000 pack horses, 80,000 people, and 2 million taels of military rations...... Your Highness, don't you want to attack Luosa City directly? This—this is really ......."

Liu Youqiu frowned, surprised by His Royal Highness King Yong's magnificence, and at the same time worried.

Among these military supplies, war horses, pack horses and other livestock are still down, although the Longyou pastoral affairs are slightly sluggish compared with the beginning of the country, but the crowding can still be made. But with so many animals gathered in the source of the river, it was also a troublesome matter to raise food.

As for the required military force, the Anxi garrison has made the people of Longyou Prefecture miserable, and King Yong in Longzhou also heroically said that he wanted to reduce the mediocrity of the prefectures, which is naturally a headache.

But the most troublesome thing is the military rations needed. This is the most important, and at the same time compared to the requirements of King Yong, the gap is also the largest, Liu Youqiu sighed: "Now in the states of Longyou, the valley is worth three million Hu, deducting the preparation of materials in the states for disaster prevention, can draw up for the military less than one million Hu......"

When Li Tong heard this number, he couldn't help frowning: "Huge Longyou, there is so little grain controlled by the government?" ”

It must be known that the town of Heyuan Army cultivated thousands of hectares of land in its heyday, with an annual income of more than 5 million hu.

Although not all of them are as suitable for reclamation as Shanzhou, where the Heyuan Army is located, there are large tracts of land suitable for cultivation in Liangzhou, Lanzhou, Weizhou, Ganzhou, Guazhou, Taozhou, and other prefectures. Although it is not as large-scale as the Heyuan Army, the annual rent is not a small amount.

Compared with the huge volume of Longyou, the accumulation figure mentioned by Liu Youqiu is simply ridiculous.

Liu Youqiu withstood the terrifying gaze of His Royal Highness King Yong, although this was not his main responsibility, but he still explained stubbornly: "So such a thin reserve, one is that the Longbian states are indeed inferior to Guannei and Heluo. The second is that there are frequent side affairs, and it is difficult for the treasury to survive Chen Gu for many years......"

When Li Tong heard this, he couldn't help but be silent again, not to mention anything else, just the four towns of Anxi were lost and recovered, and the defeat of Wei Zhi's western expedition during the Yongchang period had already greatly damaged the vitality of Longbian. The situation in this situation is already complicated, and there has been no nameless pastor to govern the people's livelihood for a long time, and it is indeed not called a great governance.

Zhuzhou has more than 300,000 grains, this number is very large, and it can be apportioned among the states, each state is only a hundred thousand grains, and the 100,000 army can eat clean in less than a month.

However, these accumulated grains will also be used to maintain the operating expenses of the state capital and cope with various situations, which are already in danger under the safety line, and once they are transferred to the military, the livelihood of Longyou will become more difficult and cannot withstand any fluctuations.

"Longyou is not without food, but it is not under the control of the government. This realm is mostly a wide township, and the mansions in Zhuzhou are just ordinary, only because of the turbulence of the border, they are accustomed to accumulating valleys and preparing for trouble, and they are not happy to sell in the market. There are also Zhuhu Prefectures that are gradually accustomed to cultivating mulberry, but they pay their own tribute and do not go to the household department, so they are also rich in reserves, and people can't afford it. ”

Li Tong breathed a sigh of relief when he heard this. It is difficult for a good woman to cook without rice, and if Longyou is really hungry and can't squeeze out any oil and water, he is helpless. But as long as there is money and food, no matter where it is hidden, it is nothing more than looting.

Of course, looting is also a matter of strategy. Violent law enforcement, like in Chang'an, which directly raids homes, is not universally applicable in Longyou. After all, those nobles in Chang'an were parasitic under the imperial power, and they couldn't escape if they wanted to.

But these wealthy families and Hu chieftains in Longyou are not highly compliant, and once they are persecuted too much, they may rebel on a large scale, so they still have to pay attention to rhythm and strategy.

If you want people to obediently hand over the money and food, although there are thousands of means, you can't get rid of coercion and temptation. In this regard, Li Tong is an expert, and as soon as his eyes roll, many ideas came to his mind.

"Tell the states, retrieve the registered high-ranking households, because of the reclamation, ten acres are turned, and the high-ranking households in the prefectures will report to each other, and the fields will be awarded."

Although Datang's meritorious service system has long been broken, it still has a certain attraction among the people. The twelve turns of Cexun mean that as long as the family has 120 hectares of land, they can be awarded the Pillar Kingdom. It's not to make you bankrupt, just report it, and it's beautiful to think about it.

And as long as the high-ranking families in the states are willing to report, it means that they still have a high degree of recognition of the imperial court's meritorious system, and their obedience is higher, and they will be better to operate in the future.

According to the current level of cultural popularity, Li Tong estimates that there should not be many households who know that Emperor Wu of the Han Dynasty "calculates and sues" flowers. Although the method is a bit disgraceful, it is also for the sake of the community.

Since you own so much land, it means that you enjoy the convenience of more border army protection, and it is reasonable to pay some money and food to help the army. Otherwise, if you really wait until Tubo Kou enters Longyou, it will really be a mouse saving rations for the cat, and he wants to cry without tears.

For the high-ranking families of the Tang Dynasty, Li Tong also has to pay attention to a strategy. But for those Hu chiefs who are already rebellious, they are much more rude.

After talking about the decree of reclamation, he said in a murderous voice: "Have you sorted out the list of Huzhou chieftains who have not given gifts?" ”
