After lunch, everyone came to the sand table classroom early, because a competition in the afternoon was a sand table deduction. This is another exchange that examines the ability of the cadets on both sides to command operations.

Under the leadership of the team leader, the Japanese personnel followed the Chinese team members in, and the personnel of both sides gathered in front of the huge sand table model to inspect the condition of the sand table model together.

Xiao Linghu knew that this model had been here for a long time, and the last lesson they had taught last time was to use this sand table to practice the follow-up situation of the "128 Songhu War of Resistance Against Japanese Aggression" in 1932 four years earlier.

The Japanese are also carefully looking at the entire sand table, which is a topographic model of the Yangtze River Delta with Shanghai as the frontier and Nanjing as the backing, with rivers, towns, railways, highways, and even small villages with only a few families marked.

In fact, the Japanese have long been familiar with China's topography, and they have been sending spies to survey China's territory for many years, and their maps are more accurate than the official Chinese maps, which also shows their ambition.

The Japanese have long been very clear about the terrain of this sand table, so there is no need to hide it from them.

After the Chinese and Japanese team members watched for a long time, the Chinese liaison officer Shangguan Hong first said to the Chinese team members: "Everyone has seen this sand table, this is the map of the Shanghai-Nanjing-Hangzhou region near Shanghai, mainly the topographic map of Songhu. As he spoke, he glanced at the ten team members present and said the title of this exercise: "Today's topic is, if there is a war between China and Japan in the Shanghai area, who can win!" ”

The Chinese team members all nodded, this topic is also closely related to the facts, China and Japan are tense, maybe there will really be another battle in the Shanghai area.

While the Chinese team members were thinking, the Japanese team leader, Kuramoto Miya, also told the Japanese team members the topic of today's exercise in Japanese, but contrary to the silence of the Chinese team members, the Japanese team members immediately became excited, and it seems that they also had this similar military chess practice class in school.

Then, the hosts of both sides introduced the rules and conditions of the exercise to each team, and the winning rule is very simple, that is, whoever occupies the Shanghai area will win. However, the conditions are not complicated, and in the case that the two countries do not expand the war and are limited to local wars, they will only achieve their goals by purely military means.

The Japanese side was the main attacker, and the number of troops that could be mobilized was 100,000; As the defending side, the Chinese side can mobilize 300,000 troops.

The Japanese army was deployed in the Hongkou Concession of Shanghai, with 3,000 troops, 10 warships on the Huangpu River and Yangzijiang River, and 2,000 marines. One division of 15,000 men was located in North China, and the other 80,000 men were based in the Japanese mainland, and they had to be transported by warships to reach Shanghai, and they could only arrive in batches and steps.

The Chinese army was dispositioned, the closest was in Suzhou, with three divisions, and then Chinese troops were stationed in various cities around Shanghai, the farthest being an army group in the direction of Nanjing.

In terms of troops, the Chinese side has the upper hand, but considering the issue of weapons and troops, the exercise was carried out according to the casualty ratio of China and Japan to one, and the 300,000 Chinese troops against the 100,000 Japanese troops were also evenly matched.

However, Xiao Linghu knew that the combat effectiveness of the Chinese and Japanese armies was far from being three-to-one, and he had heard his father, Xiao Huang, who was a senior staff member in the General Staff Headquarters at this time, say that if China and Japan went to war in an all-out manner, compared with the combat strength between the two countries, he was afraid that only five Chinese soldiers would not be able to withstand the last Japanese soldier. This deduction is calculated according to the casualty ratio of the two sides to three to one, which is really high-valued.

After the conditions of the two sides are finished, in order to save time, so the two sides only allow one person to operate on the sand table, as for the discussion later, it can be carried out in private, once one party moves, the other party must carry out the corresponding action within two minutes, if it is overtime, it is regarded as no action.

After the two team members discussed, Xiao Linghu naturally became the captain of the Chinese side, and Tachibana Jun naturally became the captain of the Japanese side.

After guessing the coin, Xiao Linghu won the first move, so he could get out of the first part.

The so-called sand table deduction is actually just a high-level form of military chess.

As the starting point of the first move, Xiao Linghu discussed with a few classmates and immediately pushed the two divisions in Suzhou to the Japanese concession in Hongqiao, Shanghai, with the simple purpose of occupying the bridgehead established by the Japanese in Shanghai and driving these Japanese soldiers into the sea. In order to prevent Japanese reinforcements from coming from the sea, he mobilized five divisions from the rear to deploy defenses on the Yangtze River and Huangpu River along the line from Liuhe, Wusongkou and Wangjiawan, in order to prevent the landing of Japanese troops at sea.

After a moment's thought, Tachibana Jun reacted to Xiao Linghu's offensive. First of all, relying on the original Japanese concession forces near Hongqiao in Shanghai, relying on strong fortresses and fortifications, to block the attack, and at the same time using warships, carrier-based aircraft and other weapons in the Huangpu River and the Yangtze River to provide strong fire cover, on the one hand, a division was transferred from North China to rush to Shanghai from Tianjin; On the other hand, two divisions were quickly transferred from the Japanese mainland to reinforce the Japanese army in Shanghai. Because of the limited transportation capacity, the Japanese mainland troops had to wait for the transport ships to turn around before they arrived one after another.

In the face of the stubborn resistance of the Japanese in downtown Shanghai, Xiao Linghu besieged with the strength of two divisions, which was indeed stretched, even if the Sino-Japanese and Japanese forces were compared to three to one, the three thousand Japanese defenders were equivalent to nearly 10,000 ** defenders, and then the defenders were guaranteed by fortifications and fortresses, so the theory of the five attacks in the "Art of War" required five times the strength of the troops if they wanted to take the Japanese barracks. In addition, because the Japanese army had the support of warships and air planes on the Huangpu River, it was difficult to shake even five times the number of troops, so Xiao Linghu could only transfer two more divisions from the rear into the downtown area of Shanghai and besiege the Japanese barracks in Shanghai with the strength of four divisions.

On the tenth day of the battle, the Japanese reinforcements arrived one after another, first landing on the front line of Baoshan and Chuansha along the Yangtze River, and fighting fiercely with the five divisions of the squadron deployed here in advance.

The five divisions of Jiangfang were obviously not enough, so the follow-up squadrons also drove to Jiangfang in a steady stream, and at most, it had reached ten divisions. According to the first type of class A, the full strength of the infantry division should be more than 12,000 people, but in reality, aside from the shortage of non-combatants and empty salaries, it is very good that a division can have more than 8,000 people, even if it is 10 divisions, according to the ideal state, the strength is only more than 80,000 people.
