On December 29, 38, the Japanese Fifth Division had occupied Nanning, Guangxi for more than a week, and although the soldiers and civilians of Nanning had resisted desperately a week earlier, there were less than 3,000 defenders in Nanning. So even if nearly 10,000 soldiers and civilians desperately tried to stop the Japanese attack. However, it still failed to withstand the attack of Japanese planes and artillery and fell.

It was also on this day that Wang Ching-wei, a bigwig of the Nationalist Government, issued a telegram expressing his willingness to negotiate peace with Japan for the two countries, but in fact he had defected to the enemy.

Since Wang Ching-wei was the vice chairman of the Nationalist Government at this time, and his position within the party was second only to Commander Chiang, Wang Ching-wei's defection to the enemy led to a response from a large number of local warlords who were unwilling and suppressed by the Nationalist Government.

At the same time, because Wang Jingwei has always been strict with himself in the Nationalist Government and has no bad habits, he has always faced the world. Therefore, when Wang Jingwei, with the support of the Japanese, secretly formed a new Nationalist Central Committee in Shanghai, he received not only the response of many old warlords, but also a large part of the so-called capitulation elite.

And because of Wang Jingwei's gentle hand, he not only got many warlords to take the initiative to vote, but also recruited more than 100,000 prisoners of war of the Nationalist Army, and Wang Jingwei's arrogance soared for a while.

On the other hand, Commander Chiang of the Nationalist Army was hit hard in Chongqing, and on the one hand, he had to strictly guard against the bribery of various party and government officials in Chongqing by Japanese spies, and on the other hand, he had to guard against Wang Jingwei's co-optation of party and government officials.

At the same time, due to Wang Jingwei's rebellion, Wang Jingwei pulled away more than 100,000 troops, which is equivalent to the Japanese army having more than 100,000 allies out of thin air.

Under these circumstances, Commander Chiang was unable to fight back at all, so he could only seek self-protection first, so his original plan to counterattack the Japanese army in a short period of time had to be forcibly stopped.

And with Wang Jingwei and Commander Chiang fighting in the ring, the Japanese army, which had become the end of the crossbow, just repaired it in order to fight again. Although at this time, the Japanese army in various parts of the Republic of China was in a state of rest. However, the Japanese army thought that it was not a problem to deal with a small Hainan Island.

Therefore, after the 21st Army of Guangdong occupied Nanning and cut off the direct connection between Hainan Island and the mainland. The troops began to divide into two routes, preparing to attack from the Qiongzhou Strait and Sanya, the southernmost corner of Hainan.

In their minds, there are at most 10,000 or 20,000 regular troops on Hainan Island, and they dispatched dozens of warships of the Fifth Fleet and mixed brigades from Taiwan. There are also two wings of the 104th and 18th divisions and two wings of the Marine Corps, with a total strength of more than 30,000 troops.

With more than 30,000 elite Japanese troops, attacking Hainan Island, which was defended by only one or 20,000 Chinese troops, the Japanese army thought that by comparing the strength alone, the Japanese army was already killing chickens with a knife.

Moreover, the attacking troops were joint operations of the army, navy, and air force, and there were two air wings in Zhanjiang with a total of 100 planes to support the attack on Hainan.

The Fifth Fleet even dispatched the First Air Force, which will carry 100 planes from the aircraft carriers Akagi and Chiyoda to conduct a landing operation in Sanya.

On February 3, 1939, after several reconnaissance of Hainan Island, the Japanese army had discovered huge batteries located in the Qiongzhou Strait, on both sides of the strait.

With these forts, the Japanese warships did not dare to land from both ends of the strait, and more importantly, with the batteries at both ends of the strait to defend them, the Japanese army could not organize troop transports to forcibly land on the other side of the Qiongzhou Strait.

In the end, the Japanese decided that the Fifth Fleet would protect hundreds of ships carrying 20,000 Japanese troops and make a detour to the bay near Sanya, the southernmost tip of Hainan Island. The Japanese army will first carry out air strikes on various important cities in Hainan before carrying out a full-scale landing operation.

However, in order to better cooperate with the southern landing operation, it is also to test Hainan's final hole card. The Japanese first took off eight fighters from Zhanjiang and prepared to bomb the batteries on both sides of the Qiongzhou Strait.

However, the Japanese planes encountered great trouble in their first tentative bombing mission, because the batteries on both sides of the Qiongzhou Strait all had tightly camouflaged air defense positions.

However, if the Japanese army thought that these two batteries were only defended by a few anti-aircraft positions, it would be a big mistake, what they did not know was that Hainan had already had a secret weapon to deal with these Japanese air forces.

When the eight Japanese planes had just arrived over the Qiongzhou Strait, they were first intercepted by 16 planes of the Hainan Air Force.

Then, after a short air battle, the four Japanese planes saw that they were running early, and only four Japanese planes were shot down.

However, the four escaped Japanese planes did not return home, and they flew directly at a low altitude and fled straight to the strait battery of the Hainan Escort Army.

As a result, before reaching the area of the battery, it was suddenly attacked by ground anti-aircraft fire, so two more fighters were shot down on the spot.

Seeing that things were not going well, the other two planes hurriedly gave up their bombing mission and turned their noses and fled in the direction of Guangzhou, while the Hainan fighters that were chasing after saw that the two Japanese planes were fleeing in the direction of Guangzhou and did not pursue them; they circled over the strait and announced to the Japanese troops in the distance that the Qiongzhou Strait was sacred and inviolable under the escort of the Hainan Air Force.

And the Japanese air brigade lost six fighters just by showing up in the Qiongzhou Strait. This huge loss deeply stimulated the 21st Army.

"How is that possible? Eight fighters, without even seeing the shadow of the artillery, almost wiped out? The First Air Wing of the 21st Army in Guangzhou, Wing Commander Major General Saki asked in disbelief.

"Report to the general, according to the two pilots who returned, their plane was intercepted by the Hainan Air Force as soon as it reached the skies over the Qiongzhou Strait.

And it seems that the enemy knows everything about us in the air. Our planes have not yet reached the skies over the straits, they have been waiting there for a long time. An Air Force staff officer responded.

"This is impossible, could it be that we have agents of the Hainan Escort Army in our army, and they told the Hainan Air Force about the flight route of our plane?" In the headquarters of the 21st Army, an army commander asked.

"Impossible, it will take less than an hour for our plane to fly from Zhanjiang to the Qiongzhou Strait, and the entire strait is 90 kilometers long, and any place can become a breakthrough for the Air Force.

And the final offensive route of our planes is also random, and even our command itself does not know which route the attacking planes are taking, and how can the enemy's spies know? The commander of the air wing was more professional, and he immediately guessed that it could not be that the air force department had infiltrated enemy spies and caused an ambush of enemy planes on the flight path.

"Could it be a coincidence?" The army asked again.

"This is also impossible, our pilots came back to report that the enemy's fighters were hiding in the air, coming straight to our group, obviously the other side came prepared, it could not be a hasty encounter.

If it was an encounter, how could we, the elite pilots of the Imperial Japanese Army, lose more than half of the enemy planes that had not yet been killed.

And after we lost four aircraft, the enemy ambushed anti-aircraft guns on the course of our aircraft. That thing wasn't easy to transport.

The fact that the enemy was able to arrive at the designated place in a short time and ambush us must have mastered our whereabouts, and they must have some advanced equipment that can detect the whereabouts of our planes from a long distance. That's why we can make such a perfect response. After a brief moment of surprise, Major General Saki had regained his usual calm thinking.

"How is this possible, how can there be equipment in this world that can detect aircraft, planes are thousands of meters in the air, and they fly so fast.

If the Chinese had this kind of equipment, why didn't they use it when we attacked Shanghai, and why didn't they use it when we attacked Nanjing, but they would use it when we attacked Hainan, which had no strategic goals. Army Dazuo asked.

"What's so strange about that. As early as three years ago, the French and British had already developed ships that could detect distant sea movements in the dark, and a year earlier, the British company Marconi had begun mass production of such targets for the British military that could detect air and sea operations.

Scientists of our empire are also stepping up the development of this device, which is called radar. As far as I know, this kind of equipment is being developed not only in our country, but also in the United States and the Soviet Union, which can detect the enemy thousands of miles away.

It's just that I didn't expect that in China, which has no industrial base, it will also find the world's latest equipment. ”

"Could it be that the Hainan Escort Army already has the kind of radar that the general said, and if this is the case, then our Air Force will no longer be able to carry out surprise attacks on the Chinese army. And the landing force that we have assembled on the sea is in a dangerous situation. Army Dazuo was surprised.

"The course of war does not change because of one or two pieces of advanced equipment. According to our intelligence, Hainan is Li Tie's base camp. With Li Tie's close relationship with European countries, it is not unusual for him to purchase such advanced equipment from Europe.

Moreover, such equipment is scarce even in European countries, and it is impossible for them to sell it to the Chinese government in large quantities. That's why we've only come across this kind of equipment in Hainan.

Obviously, Li Tie deployed the radar in the Qiongzhou Strait to blockade the Qiongzhou Strait, but you should not forget that the whole of Hainan is surrounded by the sea, and it is impossible for Li Tie to deploy this kind of radar on the entire Hainan Island.

Therefore, we can land from any location, and as long as our air force first bypasses the Qiongzhou Strait and then enters Hainan Island from the east and west, it will certainly be able to evade the radar on Hainan Island and achieve the goal of a surprise attack. ”

Hearing the detailed explanation of the captain of the Saki Aviation Wing, everyone present had the feeling of seeing the blue sky through the clouds. They slapped Major General Saki's ass vigorously.

And after Major General Saki deduced that Hainan Island had such an advanced weapon as radar, he did not change his final attack plan. Rear Admiral Saki believes that Hainan's air force must not be strong, and he can send as many fighters as he can to forcibly attack Haikou.

He believed that in the face of great strength, all intrigues and tricks would be torn to pieces by him.
