In a hurry, winter goes and spring comes.

Deng Ai knew that if Cao Liang could make a choice, then spring would be the best time. The winter was extremely cold, the snowy weather was icy, the summer was unbearable, and the heat was hot. These two seasons were undoubtedly not a good time to send troops. Therefore, according to common sense, spring and autumn were the most ideal seasons to send troops.

Autumn is too far away. According to the current preparations of the Wei army, he can be invested in the attack at any time. Therefore, Deng Ai concluded that Cao Liang would not extend the preparation time. If he wanted to launch an attack this year, he would definitely choose spring first.

Since Yang Hu captured Jiaozhou last fall, the entire preparations for the attack on Shu have been accelerated. Many military resources have been continuously transported from the Central Plains to Guanzhong. Cao Liang specially arranged logistics officials to supervise grain transportation and grass delivery.

This undoubtedly freed Deng Ai from the heavy logistics affairs. After all, according to previous practice, as the governor of Yongliang and the governor of the Zuojun, Deng Ai needed to be fully responsible for all the affairs of the expedition, including the transportation of grain and supplies.

After all, before the troops move, food and grass take the lead, especially the major events like attacking Shu, which cannot be achieved without sufficient logistical support.

If Deng Ai devotes most of his energy to raising and preparing food and supplies, it will definitely consume a lot of his time and energy, making his time to prepare for strategies and tactics become tight and affecting the overall situation.

So Cao Liang first considered this issue. After all, Deng Ai is no longer young. People over 60 years old are much worse than those when they were young. Cao Liang arranged logistics supplies to prevent Deng Ai from being distracted and thus he could concentrate on preparing for the battle.

Moreover, not only Deng Ai's side, but also Du Yu and Yang Hu's side, Cao Liang also arranged a special person to be responsible for the supply of food and grass. The current tasks of the three governors are all prepared for the battle with all their hearts and prepared strategic matters without distraction. They don't have to worry about all the complicated matters.

The transportation of grain and grass materials in Yang Hu in Jiaozhi and Du Yu in Xiling is relatively simple. It is a transportation route that can continue to be carried by sea routes. All the grain and grass materials are transported directly to Jiaozhi County, and after landing there, they are transported to Longbian.

In Xiling, transportation is simpler and more convenient. Using the Yangtze River waterway, food and supplies can be continuously transported to Xiling.

The grain and grass needed for Jiaozhi and Xiling can be provided by Jingzhou and Yangzhou counties in the former territory of Wu. The main source is Wu County. Wu County is known as the hometown of fish and rice. The granary of Wu State is definitely not a false reputation. Now, half of the grain and grass supply of the two major armies of the Wei army and the navy are from Wu County, which shows the wealth of Wu County.

In contrast, it is more difficult to replenish grain and grass in the Guanlong area. The Guanlong area has been wars for years, and the fields are extremely barren, so it is basically impossible to achieve self-sufficiency. This time, the grain and grass to be prepared for this expedition are several times that required, so the local output of Yongliang alone cannot meet the needs.

However, the prefectures and counties in Guandong have long been peaceful and their economy is gradually recovering. The eight states of Jiqing and Yanxi have been supplying food and supplies for the 80,000 people of the Left Army, which is naturally more than enough.

But the key problem is that in terms of transportation, both people in the south have water and sea to transport grain and grass. The grain channels are smooth and the transportation efficiency is extremely high.

The northern states have long and near roads. If it is spring, summer and autumn, there are still waterways of the Yellow River and Wei River that can be used. Now it is winter. The Yellow River and Wei River are frozen thousands of miles away and cannot be transported. They can only transport the food and supplies collected by the Kanto prefectures to Guanzhong by land.

The mode of land transportation was extremely expensive, but Cao Liang made great determination to conquer Shu this time, so he had to complete the task at all costs. The court issued a mobilization order to collect hundreds of thousands of civilians and transport food and grass to Guanzhong through corvee.

The grain and grass from other prefectures and counties in Guandong were first concentrated in Luoyang, and then uniformly transported to Chang'an. During the whole winter, there were crowds of people on the long Guanluo passage. The Wei court used this method of crowds to solve the difficulties in scheduling food and grass. Before the beginning of spring of the sixth year of Xing'an, all the grain and grass supplies were over-ordered as planned.

Without this worries, Deng Ai basically no longer has to consider the issue of logistics supply. Moreover, with the in-place food and grass, the Battle of the Conquest of Shu was put on the agenda in full swing.

The correspondence between Deng Ai and Cao Liang also became frequent. Deng Ai and Yang Hu were unable to go to Jiangling to meet Cao Liang in person. Fast horse communication has become the main way for them to communicate. Many of Cao Liang's strategic arrangements were also conveyed to Guanlong and Jiaozhou through letters. Deng Ai promptly reported the preparations for Yongliang and the strategy of attacking Shu to Cao Liang.

Although there has been no war in Guanlong in recent years, Deng Ai has never forgotten his responsibilities. He sent many scouts and spies to explore Shu, gained a certain degree of understanding of the deployment of Shu army in Hanzhong and Yinping, and proposed targeted attack plans.

The biggest difficulty of Wei's attack on Shu was the steep and difficult road of Shu. In history, Wei's two military forces against Shu were both failed due to geographical advantage. Therefore, if we want to take over Shu and not solve the problem of geographical advantage, then attacking Shu would definitely have no result.

However, this time Jiang Wei adopted the defense plan of gathering troops and gathering valleys, which was a good thing for Deng Ai. First, Jiang Wei gave up the defense of the outside world, which could allow the Wei army to easily attack Hanzhong along several old ways, and would not make the Wei army unable to move forward because the Shu army set up an ambush at the dangerous pass.

As long as the Wei army enters Hanzhong, the battle situation may not be what Jiang Wei expected. Jiang Wei's main defensive method of gathering troops and gathering valleys was to establish three major defensive fortresses, Seoul, Lecheng and Yangping Pass, and build a mutually supportive defense system on the Hanzhong Plain. If the Wei army fails to attack the city, they will inevitably be trapped by food and grass and cannot last long. The Shu army will harass it with a small group of guerrillas, which will make the Wei army exhausted and will retreat after a long time.

Therefore, Deng Ai proposed a targeted strategy of separating but not surrounding and surrounding but not attacking. For the Han Le City in the hinterland of Hanzhong, he adopted the method of encircling but not attacking. For the Yangping Pass, the gateway from Hanzhong to Shuzhong, he sent heavy troops to attack him. As long as he could break through Yangping Pass, the overall situation would be alive. Not only did the Wei army have the opportunity to go south to Jiange, but the enemy of the Han Le City was like a turtle in a jar, and was at your fingertips.
