Xue Yue was a first-class general in the Kuomintang army; he made outstanding meritorious contributions in the War of Resistance Against Japanese Aggression, commanding the famous "Battle of Changsha" and was also the general who destroyed the largest number of enemies in China's War of Resistance Against Japan.
However, this unique set of "Heavenly Furnace Tactics" failed when the Kuomintang and our party were fighting for Hainan Island.

The Japanese army was arrogant and arrogant, and they looked at Changsha with a tiger's eye, and the "Heavenly Furnace Tactics" disintegrated the Japanese army's conspiracy
Hunan was an important grain station in China, an important base for grain transportation of the Kuomintang during the War of Resistance Against Japanese Aggression, and the Japanese army had always been eyeing it here, wanting to capture Changsha to block the Kuomintang's supply line, so as to wear down their will to resist the war and realize their plot to occupy China.
In 1939, the Japanese army began to formulate plans to attack the Hunan region, and then gathered a large number of troops to invade the areas where the Kuomintang troops in the Hunan region were stationed, and the commander-in-chief of this war, Okamura Ningji, was extremely excited and seemed to be determined to take Hunan.
However, the Kuomintang guarding Hunan did not eat dry food, and they saw that the focus of the Japanese attack was Changsha, so they stepped up their defenses in the areas along the Changsha line and decided to lure the enemy here to annihilate them in one fell swoop.
In the previous battles, the Japanese army was the first to occupy various transportation resources, using these advantages to attack the Kuomintang army, making them invincible, and finally defeated.
This time the Kuomintang army learned its lesson, they used all means to destroy the roads and railways along the Hunan and Jiangxi regions, and the local people also knew that this was anti-Japanese resistance, and they helped the Kuomintang army to demolish them together, making it difficult for many large weapons of the Japanese army to transport.
However, despite this, the Japanese army relied on its own advantages to burn and loot in the border area, killing many innocent civilians and snatching a large amount of food.
The Second Battle of Changsha was still at a disadvantage, because of the mistakes of the command of the Ninth Theater, so the Japanese army once occupied Changsha, the Kuomintang army suffered heavy losses, the defeat of the first two battles made the Kuomintang army begin to reflect on its own strategy and tactics, Xue Yue proposed the famous "Heavenly Furnace Tactics".
In fact, during the previous Battle of Wuhan, Xue Yue had used the "Eight-Character Pocket Tactic" similar to the "Heavenly Furnace Combat Method", but the principle of the "Eight-Character Pocket Tactic" was relatively simple, that is, to lure the enemy deeper, then surround the enemy and annihilate it in one fell swoop.
The "Heavenly Furnace Method" is to concentrate all the troops in important combat areas, divide them into three roads, left, center, and right, and then quickly form an encirclement circle to surround the enemy in the middle and beat them up, so that no matter how they flee, they cannot escape, and then they can completely annihilate the enemy army.
This method of warfare did indeed achieve amazing results, and even Okamura Ningji was surprised by Xue Yue's tactics, he never thought that the Kuomintang army would be so powerful, beating his proud "emperor elite" to the head, and the head of the Japanese army in this war, Anan Weiji, had never encountered such a tough opponent, and he was dismissed after the defeat of the war.
The Defense of Changsha dealt a great blow to the arrogance of the Japanese army, ruining their ambitions to destroy China, and after this battle, Xue Yue was awarded the Order of the Blue Sky and White Sun.
The Heavenly Furnace Tactics could hold the attack of the Japanese army, why could it not defend Hainan Island
Xue Yue's "Heavenly Furnace Tactics" resisted the repeated attacks of the Japanese army during the War of Resistance Against Japanese Aggression, and also beat the enemy to the point of not daring to continue to attack, but in the campaign to liberate Hainan Island in 1950, Xue Yue's army obviously had more than 100,000 people, so why did he finally lose Hainan Island?
First of all, Xue Yue was not valued by Chiang Kai-shek, who had always attached great importance to his concubine troops, so he did not care about Xue Yue's army for a long time, and he himself did not get much use, and it was only when the Kuomintang was completely defeated and needed to save the situation that Xue Yue was reactivated.
At this time, it was no longer a foreign war, and it was inevitable that people would be upset when they beat their own people, so Xue Yue did not have much hope for defending Hainan Island.
Secondly, the terrain of Hainan Island is complex, as long as the People's Liberation Army wants to land, there are many ports to land, Xue Yue can not judge where they will land from, and most of the combat areas of the "Heavenly Furnace Tactics" have only one centralized location, so the "Tianlu Tactics" are not suitable for the Hainan Island Campaign.
The third is that the People's Liberation Army has made full preparations for landing on Hainan Island, they have prepared more than 2,000 ships in advance, they have also loaded a large number of weapons and ammunition, and the number is as high as 120,000, plus there are also Qiongya columns led by our army that have been fighting in the Hainan Island area, with as many as 20,000 people, so the direction of this war has been basically clear.
The People's Liberation Army quietly landed on Hainan Island at night, and then joined forces with the local Qiongya column to attack the Kuomintang troops together, leaving Xue Yue to be attacked on both sides, and the famous "Heavenly Furnace Tactics" had no way to use it, so the Platony successfully liberated Hainan Island, and Xue Yue later followed Chiang Kai-shek to Taiwan.
Facts have proved that any famous method of warfare must be used under conditions adapted to it, and at that time, the liberation of Hainan Island was already the trend of the times, and even if Xue Yue used his troops like a god, it would be difficult to save the defeat.
