Su Ze looked at the map and his eyes fell on a city.

The most important thing in army operations is to push the line of troops.

Even in World War II when motorized troops appeared, ensuring smooth logistics routes was still a top priority.

Even the modern army relies more on logistical supplies than the ancient army, because the weapons and food of the ancient army can be directly robbed, but the weapons and ammunition of the modern army must be supplied by its own side, and it cannot even use supplies captured by the enemy, because the weapons The format is different.

Because of the importance of ensuring army logistics, when the army is fighting, it must control important nodes along the way.

Therefore, a series of "strategic locations" are formed on the map.

If the strategic points of some provinces are breached, then the terrain will be smooth and they can be captured quickly.

For example, Wuchang is a strategic location for Huguang. After capturing Wuchang, there will be a fulcrum to attack the Jianghan Plain. If you control Xiangyang and Jingzhou, you can control the entire Huguang.

Another example is that Jianmen Pass is a strategic location in Sichuan. After controlling Jianmen, you can have a commanding position over the center of Shu and attack major cities in the center of Shu at any time.

As for Henan, as a "Central Plains" region in the narrow sense of ancient times, it also has a long history as a strategic location.

There is an ancient route to attack Henan from Nanzhili.

Suiyang.

But now the city has changed its name. It was renamed Shangqiu in the 24th year of Jiajing.

Shangqiu, also known as Suiyang, has been guarding the gateway to Guanzhong since ancient times.

When Chu and Han were fighting for hegemony, although it was the fortress guarded by Liu Bang, the founder of the Han Dynasty, it was an important node in the attack on Huaibei.

The most famous battle of Suiyang was when Zhang Xun of the Tang Dynasty defended Suiyang during the Anshi Rebellion, firmly blocking Anlu Mountain's southward army, protecting the economic main artery of Jiangnan and Guanzhong, and finally consuming Anlu Mountain to death. Father and son.

Zhang Xun defended hundreds of thousands of Anqingxu rebels with one city. Later, the city was broken and Zhang Xun was killed. His ability to firmly defend the city was hailed as the most famous defender in history, and his integrity was also praised by later generations. People praise.

However, the strategic significance of the Battle of Suiyang is rarely known by future generations, and many people even do not understand why the Battle of Suiyang can be called the turning point of the Anshi Rebellion.

Or because of Suiyang's strategic geographical position.

The Beijing-Hangzhou Grand Canal dug by Emperor Yang of the Sui Dynasty was mainly divided into two sections.

The Beijing-Hangzhou Grand Canal is called a national destiny project. Although Emperor Yang of the Sui Dynasty was eager for success, this canal can be said to be an important project that changed China's strategic map.

The Beijing-Hangzhou Grand Canal goes north from Yangzhou and divides into two sections when it leaves Jiangsu.

The section that continues to the north is a very important water transportation channel from the Yuan to the Ming Dynasty and even to the Qing Dynasty. Taxes and grain from Jiangnan were transported to the capital through this road.

It can be said that if it were not for the northern section of the Beijing-Hangzhou Grand Canal, the capital would not have the geographical conditions to become a political center.

It is this Grand Canal that allows the capital to collect materials from Jiangnan through the Grand Canal, and also allows the capital's orders and troops to quickly move into Jiangnan, connecting the political center of the capital and the economic center of Jiangnan.

However, during the Sui and Tang Dynasties, the capital was not the capital of the country. The purpose of Emperor Yang of the Sui Dynasty in building the northern section of the Beijing-Hangzhou Grand Canal was to attack Goguryeo and transport military supplies.

During the Sui and Tang Dynasties, the political center of the country was Guanzhong, so the western section of the Grand Canal from Xuzhou to the west was the most important channel of the Grand Canal during the Sui and Tang Dynasties.

Suiyang is at an important node of this waterway.

Suiyang is close to the Bian River and is an important node for water transportation along the Bian River. During the Tang Dynasty, grain from the Jianghuai River was transported to Guanzhong through Suiyang.

During the Anshi Rebellion, An Lushan, An Qingxu and his son were still unable to conquer Guanzhong after capturing Luoyang. One of the important reasons was that the Tang Dynasty at that time could still control the Jianghuai River and transport these materials to Guanzhong through the Grand Canal.

So for Henan, Suiyang is the gateway to Henan.

After occupying Suiyang, the southeastern army could transport supplies through the Bian River and attack Luoyang.

Although Chen Yiqin was a civil servant, he could also fight. Therefore, Chen Yiqin focused on consolidating the city defense of Suiyang in Henan, and even established a naval force to guard Bianshui River.

Chen Yiqin invested heavily in Suiyang, and originally this line of defense was relatively stable.

Shandong was in the hands of the Ming court. The only troops Su Ze could use to attack Suiyang were Xuzhou's troops. The dispatch of Xuzhou's troops would cause the Huaibei defense line to be empty.

Although Chen Yiqin and Li Chengliang were at odds with each other before, Shandong and Henan were actually horns of each other, creating military pressure on each other and forcing Xuzhou's Southeast New Residence not to dare to act rashly.

But now there's a turnaround.

In order to consolidate Li Xun's army and control the nine sides, Li Chengliang took away two of the three towns in Shandong and the Ming Ting's new army.

Although two towns were subsequently recruited in Shandong, the new Shandong troops in these two towns were incomparable to the recruits in the three towns directly under the Ming court.

Li Chengliang also knew this. The recruits in the two towns in Shandong were all new recruits. Their weapons and equipment were also backward, their training was poor, and their combat effectiveness was very poor.

However, Li Chengliang's goal is to defend Shandong. With the Ming Ting New Army in one town and the Shandong New Army in two towns, relying on the fortifications Li Chengliang has operated in Shandong over the years, the problem of defending is not big.

However, Shandong's lack of military strength also broke the dichotomy between Shandong and Henan.

The Ming Ting army in Shandong can only defend but not attack. So can the fifth town of the Southeast New Army in Xuzhou be moved?

Xuzhou still has railways, and only a small number of mobile troops are needed to let go, and Li Chengliang may not have the courage to mobilize the Shandong Mingting to fight the southeast march.

Then let Chen Lin lead his troops to the west to attack Suiyang (Shangqiu) and capture this gateway into Henan?

If Suiyang can be captured, troops from Huguang can be mobilized for reinforcements and Henan can be captured at once.

If Suiyang cannot be attacked, Chen Yiqin will definitely ask for help from Mingting, which will consume Mingting's strength.

If the Ming court does not provide support, it will cause Henan to become even more centrifugal.

In short, attacking Suiyang is a sure-profit business.

After figuring this out, Su Ze immediately summoned people from the Army Department of the Cabinet to discuss the feasibility of this strategy.

Naturally, everyone expressed their support. The Ministry of War also stated that two thousand soldiers from the 6th Brigade who had returned from Annan for rotation training were still resting in Nanjing. These soldiers could be sent to Xuzhou to take over the defense line of Chen Lin's 5th Brigade and let Chen Lin Lin can lead all the troops to attack Suiyang.

And as a strategic front line, enough military supplies have been hoarded in the Xuzhou area to launch this attack.

Originally Su Ze's strategy was to attack Yunnan and Guizhou first and then attack Shandong. Now that Yunnan and Guizhou have surrendered and Henan has exposed its flaws, it is natural to let this opportunity pass.
