Unable to capture the Solomon Islands, Bougainville has become a U.S. submarine base, with ocean-going submarines already frequenting the Ogasawara Islands, the Bass Strait, and the Balintang Strait, attacking Japanese freighters and, occasionally, near Taiwan, Japanese supply fleets passing through the straits.

The Taiwan Strait is the busiest area for Japanese military transport, and American submarines are increasingly turning their attention here, of course, most of the time in the waters north of Kenting, and the planes of the Tainan Air Force often see submarines roaming the sea, sometimes one, sometimes two. But north of Keelung, it's less common.

Eisaku Sato did not dare to take it lightly, enemy submarines are rare, and it does not mean that they will not appear around the Noh codename. If the captain of the U.S. submarine happened to pass by and spotted the huge, motionless ship, he would most likely attack. Now there are only 6 destroyers and luck that can protect this valuable salvage ship, and in a way, luck is more important than destroyers.

So far, the disability rate of divers who have gone down is 10%, which means that one in ten people will be left with lifelong disabilities due to latent disease, most of them are heart-lung blood vessels or eardrum rupture. The news that came below was still only half cut.

Japan's precious divers and helium resources are slowly being depleted. On the bright side, the enemy still hasn't set their sights on here.

Yamashita Fumi, who was on the front line, was appointed as the temporary commander of the Southern Army, and Army General Anan Yuki, who succeeded Terauchi Shouichi, was on his way and could take up his post in a few days.

The base camp realized the most terrible situation. It is Chief Chu Ting's army, and the US Navy may take a joint operation to directly cut off the entire road traffic and sea transportation line. Imagine that Trung Chu's army captured Vietnam and the U.S. Navy appeared in the South China Sea, and the connection between the huge southern combat group and the mainland would be completely cut off. It was under these circumstances that Anan was entrusted with the important task of going to the south to put out the fire. The military department took into account that Anan was a general who was good at decisive battles, and now it was not a wise general who was good at skillful warfare, but a person who had the determination to resist to the death, and such a person would cooperate better with Yamashita.

In the afternoon of the same day, Yamashita received the news that Major General Yasujiro's 48th Brigade had entered Phnom Penh, and the whole process did not encounter the enemy, who left two hours early. Left behind a devastated palace.

The king led his family at the gate of the palace to greet Major General Akashi, crying and telling about the brutal sacking of the Chinese army, and even snatching an ancient painting from the emperor, and he mentioned Marshal Terauchi's death-defying death at the last moment. Everyone who heard it was moved to tears.

Yamashita decided not to return to the army for the time being, that must be what Chu Tingchang wanted to see, and he had to block the road to give Chu Tingchang a problem. He knew that Shizuo Yokoyama's 8th Division was approaching, and that the 6th Division would soon land in Phnom Penh. It's too late to restrict Zhou Youfu from running around behind him, but he can wait for him to consume fuel and ammunition and stop. He received information that the oil depot in Phnom Penh had been destroyed in time, that the enemy had not gained much, and that the enemy's ammunition should not be replenished. Using a set of experiences from the Japanese Army, he came to the conclusion that the enemy would not be able to sustain himself. According to the army's own statistics, the daily consumption of materials by mechanized wings is 10 to 20 times that of ordinary infantry wings. It is almost impossible to sustain such a deep battle with the enemy.

Zhou Youfu did not weaken according to the idea of the mountain, and he set his sights on the Japanese strategic airfield in Wudong, north of Phnom Penh.

The airfield was originally under the direct jurisdiction of the Southern Army, but because it was far away from various battlefields, it only served as an air transport hub, and there were no fighter bomber units stationed there.

The airfield was heavily guarded, with a large number of 75-mm anti-aircraft guns and even two 120-mm anti-aircraft guns. There were a large number of * and * in the warehouse, which were originally intended to be shipped to various battlefields, but these* were enough to blow up the two runways of the airport several times, and if the Japanese had understood the purpose of Chu Tingchang, they should have blown up the airfield instead of holding on to it. However, the Japanese commanders did not yet understand the rudimentary form of mobile warfare, let alone vertical supply and airborne operations behind enemy lines.

Before Zhou Youfu's troops arrived, Le Duan's guerrillas had already provided information about the enemy's airfield garrison and the surrounding terrain in advance. The airfield is located on a plain, with a Japanese military highway on one side and a water network on three sides. The Japanese garrison of the airfield was the 25 Airfield Brigade and the 75 Field Anti-aircraft Artillery Brigade, with a total strength of 2,000 people.

When the enemy received the news of the occupation of Phnom Penh, he immediately began to prepare for battle, but the Japanese commander who was garrisoning here did not spend his limited * on blowing up the runway, he probably thought that he could hold out. So they buried * on the road, and deployed large-caliber anti-aircraft guns to the side facing the road. The flat-firing power of these Type 88 75-mm anti-aircraft guns far exceeds that of the 37-mm tank guns of Zhou Youfu's tank unit. This is probably the confidence of the Japanese army.

The guerrillas only superficially reported on the radio that the enemy had more than a dozen anti-aircraft guns, but the scouts' observations of the enemy's weapons could only be drawn on a map, and the map was difficult to inform the rear through radio statements. So it's a mess.

However, this telegram arrived at the headquarters of Chu Tingchang, and a miracle happened. All the chaotic information was sorted out clearly, in fact, when Zhou Youfu was 15 kilometers away from the airport, he got the map of attacking the fortified position thrown by the liaison plane of Chu Tingchang's headquarters, and every gun position of the enemy was drawn very accurately. This is, of course, the credit of the 419 drone. Moreover, through the accurate mapping of the UAV, the firing range and dead angle of these gun positions have been roughly obtained, so that Chu Tingchang directly gave Zhou Youfu an attack order. He was asked to bypass the front and attack from the low-lying areas on both sides.

Zhou Youfu had some doubts about Chu Tingchang's plan, and when he followed the 5th Army to South China, he suffered losses in the water network area, and saw several tanks stuck in the rice fields and could not climb out, only to be destroyed by the enemy. Especially in the current situation, the airfield is empty on all sides, and even if the troops are outflanked by the rice fields on three sides of the water network, the enemy's anti-aircraft guns can still turn their guns to strike at their moving tanks. Unbeknownst to him, of course, accurate synthetic aperture radar terrain detection showed that even though the enemy could see the tanks moving around at any time, the anti-aircraft guns they deployed were all located at a high position, and there was a shortage of lethal high and low firing ranges. This point was something that Chu Tingchang couldn't explain clearly for a while, but the offensive routes he marked were all in the lowest place.

Zhou Youfu put forward his opinion to the military department, he believed that outflanking the rice fields would slow down the tank, and it was taboo to use weak armor on the side against the enemy. He suggested either waiting until the evening and flanking or just frontal during the day. Either way, he was sure to take the airport.

Chief Chu Ting's reply only asked him to act according to his plan, and specially instructed that when outflanking, he should not stay away from the enemy's artillery because he was afraid of them, and strictly follow the designated route. Lao Zhou felt that the military seats were separated by 100 kilometers, and relying on the aerial photos taken by the Americans and the reconnaissance reports of the Vietnamese, he might not be able to grasp the overall situation, especially the requirement to be close to the enemy's artillery position, which was really incredible. But his trust in the commander reached the point of blind obedience after all. Historical experience tells him that the orders of the army commander must be carried out if he understands and those who do not understand, because in the end he is always right, and he is protected by the gods.

So he ordered his troops to be divided into two routes, divided the remaining 20 or so tanks into two teams, outflanked them from both flanks, and strictly ordered them to follow the demarcated route and not to stay away from the enemy.

Tanks and half-tracks launched an attack on the enemy's airfield.

The garrison noticed that the enemy had abandoned the frontal assault and switched to outflanking on both flanks, which was of course not a problem, and all these anti-aircraft guns had a 360° firing range, so the enemy could not run out of his hands.

But something terrible happened, the artillery could clearly see the target, but - 1.5 degrees of downward firing range, it turned out to be not enough, it was just a little bit worse, and the enemy passed under the nose.

The soldiers on the gun emplacements began to push the anti-aircraft guns with their hands and feet, but these heavy weapons were so easy to move. At this time, the machine guns on the tank could reach the enemy's gun emplacements.

For a time, the enemy was losing ground, and the Japanese commander stationed at the airfield received an order from Shangfeng to destroy the airfield immediately, but it was too late. The speed of the tank's movement was too fast, and the commander was in the airport tower, watching the tank group move rapidly in the rice fields on both sides, and then with the help of the buildings and aircraft on both sides, he killed himself. He only heard that Rommel used anti-aircraft artillery in North Africa to beat the opponent's armored troops, but why are there so many ghosts of the enemy's armored troops he encountered?

The Stuart tank stormed the airfield, and the machine guns were used* against the anti-aircraft gun emplacements that were still desperately turning their muzzles, and as soon as they hit the ammunition, they would trigger a chain explosion that would blow the emplacements into the sky.

Within 20 minutes, all the enemy's deployment was bulldozed by Zhou Youfu's tanks, and he immediately received an order from the Chu military department to ask for a reasonable runway at the airport, so he hurriedly pushed away the enemy's artillery and transport planes that had been blown up at the airport, but fortunately he had tanks of more than ten tons, which could be used as bulldozers if necessary. Then fill some of the craters with mud, and that's all there is to it for the time being.

More than 20 P38 fighters flew over the airfield in order to control air supremacy in this area, but the enemy's light fighters did not appear. In the vertical landing plan designed by Chu Tingchang, full air supremacy was not required, but he needed a certain window of time to lower the transport plane and send his supplies and Hongxiang troops, as well as a field hospital. In addition, it is necessary to bring back the seriously wounded of Zhou Youfu's troops. Since Yamashita Fengwen used his bicycle to fight a blitzkrieg and was worshiped as Japan's god of mobile warfare, Chu Tingchang was going to teach him a lesson today and let him know that bicycles are not really a trend. His group of transport planes was approaching, and at this time it was in the midst of a period of confusion in which the Phnom Penh command had been destroyed, and all the fighters on the enemy's airfields could not receive effective interception orders.
