The military transport plane landed at Nanning Airport, and Ouyang Jian stepped off the plane with several Ministry of Defense officials. Bai Chongxi, commander of the 4th Theater Theater, Du Luming, commander of the 5th Army, and Zheng Dongguo, chief of staff, and other generals greeted them at the airport. Du Luming and Zheng Dongguo are both in the first phase of Whampoa, Ouyang Jian, as an alumnus of the first phase of Whampoa, Du Yuming and Zheng Dongguo should be "old acquaintances", and Ouyang Jian is not bad at all in terms of qualifications. Bai Chongxi and Ouyang Jian are also old acquaintances, so there is no need to introduce the scene of the meeting in detail.

Since Zheng Dongguo concurrently served as the commander of the Rongyi Division, Du Yuming only introduced the two division commanders under his command, and Ouyang Jian shook hands with the 200th division commander Dai Anlan. inquired in detail about the situation of the ministry, which caused the generals to be confused, thinking that Ouyang Jian had a special relationship with Dai Anlan. When Ouyang Jian shook hands with Qiu Qingquan, the commander of the 22nd Division, and Liao Yaoxiang, the deputy commander of the division, he was just polite. Qiu Qingquan belongs to Huangpu Phase 2, Liao Yaoxiang belongs to Huangpu Phase 6, and they have become Ouyang Jian's "juniors" in terms of qualifications, but their names Ouyang Jian are naturally familiar.

The 5th Army was an elite unit newly formed before the start of the Shonan defensive operation. After the Japanese army occupied Guangzhou, in order to cope with the situation in the south and ensure the security of Guangxi and Hunan, Lao Chiang installed all the military equipment aided by the international community in the Fifth Army. The 1st and 2nd regiments of the 5th Army are equipped with 78 Soviet-style T26 tanks, 100 German-style armored fighting vehicles, and more than 400 American-made Ford trucks. In addition, the heavy artillery regiment under the army is equipped with 24 150-mm heavy guns, and it can be said that the weapons and equipment of the 5th Army are the most powerful in the units of the Central Army.

The victory in the defensive operation in southern Hunan gave Lao Jiang full confidence. After the end of the Shonan defensive operation, the Japanese army realized that the land war could no longer achieve its operational objectives. For this reason, the commander of the North China Dispatch Army, Okamura Ninji, sent a letter to the base camp to consolidate the occupied area while avoiding fighting with the elite troops of China. It is proposed to use the huge fleet to achieve strategic objectives along the coast of China, completely blockade China's coast, and cut off all ties between China and the outside world.

The Japanese base camp adopted Okamura's suggestion and ordered the formation of the General Headquarters of the Chinese Dispatch Army in early May, with its headquarters in Nanjing. He also appointed General Nishio Toshizo as the commander-in-chief and Itako Seishiro as the chief of staff, and successively formed the 60th Army, the 70th Army, and the 80th Army. The Japanese base camp believed that it was temporarily impossible to take Hunan and Jiangxi by land, so the strategic plan was adjusted as follows: Occupy the southern coast of China, first cut off the external passage of the Guangxi coast, cut off the Yunnan-Vietnam railway between Vietnam and Guangxi and Yunnan, and then cut off the supply line of the Yunnan-Burma highway.

The Japanese base camp believed that while cutting off the external supply lines of Chinese mainland, the Japanese army went north to take Nanning and Guilin, forming a north-south attack and preparing to attack Sichuan. At present, Germany is invincible in Europe, and a tacit understanding has been formed between Germany and Japan, and it is just a paper away from an open covenant. The international situation was very favorable to the Japanese army, and Germany completely attracted the attention of Britain, France, and the United States, and Japan naturally wanted to speed up its conquest in Chinese mainland.

The Japanese base camp issued an order to form the 21st Army, with its headquarters in Guangzhou. The 5th Division, the Guards Division, the 38th Division, and the 55th Division of the Japanese Army were requisitioned and transferred to the 18th Division, the 104th Division, 4 Army Aviation Wings, two heavy artillery brigades, and one armored brigade in Guangzhou to form the 21st Army Combat Corps, with a total strength of 200,000 troops. The commander-in-chief of the Chinese Dispatch Army, Nishio Toshizo, appointed Lieutenant General Michiro Furujo as commander of the 21st Army, responsible for directing the operation. In order to achieve the purpose of the campaign, the Japanese army dispatched the 5th Fleet, including two aircraft carriers, and more than 80 large and small warships to support the operation.

When the Japanese army was moving militarily, the Ministry of National Defense also learned of the Japanese army's southern battle plan, and Lao Chiang ordered the 5th Army to go from Hengyang, Hunan to Guangxi to join the 4th Theater, and at the same time ordered Bai Chongxi to serve as the commander of the 4th Theater to be responsible for commanding the operation. Before departing from Chongqing, Ouyang Jian and Lao Jiang had a secret conversation for an hour, Ouyang Jian proposed to form a strong defense line on the Nanning and Wuzhou lines, and blocked the Japanese army on the Nanning line to the greatest extent.

On the plane, Ouyang Jian carefully calculated, it was now mid-May. According to the speed of the Japanese army's build-up, it was necessary to complete the campaign preparations in September at the earliest, and launch an attack in October, which was not much different from the original history. The only change was due to its own butterfly effect, after the Japanese army occupied Shantou, it did not make a move on the coast of Fujian. In order to avoid fearless battle losses, the Japanese army abandoned the battle plan to occupy the coastal areas of Fujian. After the end of the defensive operation in southern Hunan, Ouyang Jian submitted a report to the headquarters of the Eighth Route Army.

Runzhi believed that Ouyang Jian's analysis was correct, and then the headquarters of the Eighth Route Army ordered the 1st Army Corps to leave a corps in southern Fujian to serve as a defense, and let Lin lead the two corps to the south of Ganzhou, and form an east-west defense line with Xue Yue's corps to prevent the Japanese army from attacking north from the west of Jiangxi. Ouyang Jian judged that due to the butterfly effect in Jiangxi, the original historical strength of the Japanese army in the south would be changed, and there would definitely be a large increase in troops. It turned out to be 100,000 troops, but now it is highly likely to be doubled, and the Japanese army is not a fool, this is inevitable.

The original history, Bai Chongxi set up a defense line of thousands of kilometers in Guangxi and Guangdong, and the paving was too big. 400,000 troops defending thousands of kilometers of defense is undoubtedly a drop in the bucket. It was necessary to tighten the five fingers and focus on the defense, and at the same time inflict heavy losses on the Japanese army. If the Japanese army fought in the south, if the front line was extended, its logistical supply would be more difficult, and as long as the Japanese army was blocked on the Nanning line, it would also force the Japanese army to turn to Vietnam. In Ouyang Jian's mind, the Yunnan-Vietnam Railway is no longer important in the future strategy, and even the Yunnan-Burma Highway is insignificant.

The Japanese army wanted to capture Vietnam and even Burma, which was more in line with Ouyang Jian's strategic concept. The Japanese army helped drive out the French and the British, why not. In the future, the Japanese army will maintain strong military pressure on India, and Ouyang Jian knows very well how much of a threat it will be to the Americans. At present, the US oil industry in Kuwait is very large, the Persian Gulf is inseparable for the Americans, and the great changes in the Chinese battlefield will also make the Americans go all out.

In fact, Ouyang Jian's real purpose was to need the air support of the Americans, and then build his own air force. Second, the Americans need to build a modern navy for themselves, and Ouyang Jian already has a complete plan in his chest this time, so I won't repeat it here. In addition, Ouyang Jian needs the United States to provide a large amount of oil, which is particularly important, and it is absolutely impossible for future tank troops and fighters to do without oil. This battle in Guinan is related to the future strategy, and Ouyang Jian must be arranged in advance.

A convoy drove towards Nanning, and the southern scenery on both sides of the road was in full view. Bai Chongxi and Ouyang Jian sat in a car, and the two talked for a while about the experience of defensive operations in southern Hunan, and Ouyang Jian changed the topic and said: "Brother Jiansheng, Guangxi is your hometown, and it can be said that one side of the water and soil supports the other side. The people of Guangxi are fierce, and their customs are different in the south. "I didn't expect Brother Ouyang to know so much about Guangxi, I heard that you are a northerner and have never been to Guangxi!" Bai Chongxi was surprised.

"Brother Jiansheng, although I have never been to Guangxi, it doesn't mean that I don't know anything about Guangxi. When I was in school, I was very interested in the customs and topography of the provinces. It's my first time in Nanning, but I'm already familiar with Nanning in books. "Brother Ouyang, in that case, you might as well describe your impression of Nanning." "Since Brother Jiansheng has such Yaxing, I will be ugly, what I said is not right, please Yazheng."

Ouyang Jian pondered for a while: "Nanning was called Yong Prefecture in ancient times, referred to as Yong. As an ancient cultural city with a long history, Nanning is a multi-ethnic city with the Zhuang nationality as the main body. The Zhuang people have lived here for generations as indigenous people and live in harmony with the Han and other ethnic minorities. The unique natural conditions make Nanning full of green, evergreen all year round, with the reputation of green city, unique in the south. ”

"Nanning has a long history and belonged to the land of Baiyue ・・・・・・ in ancient times. The landform of Nanning is divided into five types: flat land, low mountain, stone mountain, hill and platform, and its topography forms a river valley basin with the Yongjiang River in the east-west direction as the center, and the rivers outside the four sides converge to the basin and form the state of the north and south hilly rivers, which can be described as a natural barrier, and the military value is very important ・・・・・・. After listening to Ouyang Jian's introduction, Bai Chongxi was taken aback and said: "Brother Ouyang is worthy of being a military wizard, frankly speaking, I am familiar with the topography and landforms of Nanning, but my knowledge of Nanning's history is almost blank. ”

"Brother Jiansheng, these things are all obtained from books, and they are not vivid and laughable." "Brother Ouyang, don't be modest, its description is lifelike, it's the first time I've heard such a subtle word, concise, wonderful, and it makes people think about it. I can say without exaggeration that your knowledgeable university professors would be inferior to themselves. No wonder they all praise you for your talent, and I learned this time. "Ouyang Jian's foreplay was intentional, the purpose was to make Bai Chongxi's conceit completely come to naught, because the next defensive operation would gather the five fingers of key defense, and let Bai Chongxi deploy according to his own wishes.

The convoy entered the urban area of Nanning, and dusk came. In the headquarters of the Nanning Theater, Bai Chongxi washed the dust for Ouyang Jian and others. During the banquet, Ouyang Jian talked with Du Yuming and Zheng Dongguo, and Ouyang Jian briefly said his thoughts about the defense deployment, and said that the key defense in Nanning and Wuzhou was what Lao Jiang meant. Ouyang Jian's purpose was to get Du Yuming to come forward and question Bai Chongxi's military deployment, and finally stand up to clean up the mess.

Ouyang Jian lifted out Lao Jiang, believing that Du Yuming would not doubt it. If Du Yuming questions it, the problem is simple.
