Due to the appearance of the elite army aviation units of the Japanese army, the heavy bombers of the 10th Air Force hid at high altitudes to destroy the railway, and they became more and more ineffective. The fighters of Chennault's 14th Air Force could only rely more on the attacks on the trains on the tracks, because according to British intelligence, the Japanese locomotives were insufficient in number, and once destroyed, it seemed to be a weaker shortcoming than the railroad to recover.

In the past, the Japanese army did not have the ability to defend against the air, but according to Hashimoto's idea, anti-aircraft gun trailers stacked with sandbags were added in front of the front and rear of the train, although it occupied the transportation capacity, but the railway could be used during the day, and to a certain extent, this was also a provocation to the air supremacy of the Allied forces, in order to defend this lifeline, the Japanese made a bloody investment.

The 5th Army was forced to attack the enemy on such a morning when the heavy artillery was not ready. Although the battle that was bound to cause casualties had always been avoided by Chu Tingchang as much as possible, the strategic significance of this transportation hub and the urgency of the timing forced Chu Tingchang to launch an attack in the absence of engineers and artillery. He couldn't wait for 419 to arrive and attack comfortably.

Xu Chong was given a new mission to lead a small team of his men and do everything he could to disrupt enemy transports.

Chu Tingchang must prevent the ammunition coming ashore in Bangkok and the gasoline and diesel refined by Ringanqiang from appearing here at the same time. So he gave Xu Chong this task that required imagination.

Of course, Xu Chong quickly observed that the enemy's train hub area was heavily guarded, and the only chance was on the railway line. Overnight, he led his men and horses to the south, preparing to bury them under the railroad while it was dark*. However, he observed that the enemy had deployed armored vehicles and rolling cars on various forks, and there were cavalry patrols on both sides of the railway.

These patrol vehicles are very dense, his troops have barely penetrated the railroad side, digging up the opportunity for land-based sales under the rails, and if the mine is not planted at the right time, it is likely that it will be a rolling car that will be detonated, and the consequence is that the enemy can repair the blown up railroad tracks within 2 hours, and the entire rear enemy will rush into the forest to chase and kill him. He had to study the rules of the enemy's trains, but then he realized that the enemy's transportation was no longer regular. They rely entirely on efficient scheduling capabilities to start planning.

It dragged on until daytime, and he couldn't do it. You can only stay at the top of the hill and continue to observe the enemy's movements. During the day, the enemy continued to use the railway to strengthen transport, which seemed to be emboldened, and several air raids by the Flying Tigers were also repulsed. Seeing that there was no way to make a difference, he saw that the train in the south of the mountain was speeding forward, and on the north side of the mountain, a steam was also approaching.

Xu Chong was far away from the railway and could see such a scene, but the two military vehicles on the same railway, separated by a mountain, could not see each other. He realized that the enemy was going to be bloody. Moreover, it is not like the enemy is busy making mistakes, and even the place where the two trains will meet, it seems that there is a choice.

Xu Chengran felt that 419 and Team Leader Lin might have returned, although Chief Chu told him that he had received the signal of 419, but the Gulf of Thailand was far away from here, and the drone whip could not reach it.

It had been a long time since he had searched for 419's signal on the radio, because without the support of drones, those things seemed useless. Now the modified walkie-talkie is being thrown away in the jungle not far away, on his half-track.

Xu Chong couldn't leave the reconnaissance post, so he called a soldier and asked him to pick up the Motorola walkie-talkie, if the 419 drone was nearby, it might receive a signal, but it was not absolute. The communication of the drone is quite directive, and if 419 does not think that this area has its own people, it may not broadcast encrypted to this area to save power.

He continued to lie on the top of the hill, watching the Japanese train approach without hesitation, without any signs of slowing down, and it seemed that a collision was inevitable.

The Japanese train, loaded with wounded, moved forward at full speed. The driver noticed a steam behind the hill ahead, and he thought there might be trouble, so he sounded the whistle. Sure enough, there was a whistle from behind the mountain. But in the blink of an eye, the ammunition transport army column on the mountain has emerged. Both sides see each other at the same time and start braking.

It was easier said than done for the two 70-kilometer trains to stop, especially the one that rushed down the slope, and it took him at least 600 meters to stop himself.

Xu Chong used a telescope to fully observe the efforts of the Japanese to prevent the catastrophe from happening, but the laws of physics cannot be changed by hysteria. With a huge inertia, the two trains collided together, one of which overturned on the spot, and the other twisted into a ball and all derailed.

Xu Chong's walkie-talkie did not receive any 419 signal, so he returned to the half-track with the radio and brought good news to Chu Tingchang, informing him that there would be no supplies from the enemy all day today.

Lieutenant General Nishioh Ojo, deputy chief of staff of the Southern Army, personally went to the Japanese army headquarters in Bangkok, and was originally going to read out a commendation order for Hashimoto in front of the officers, but he temporarily got a telegram of the train collision, which made him angry, and at the commendation meeting, he gave Hashimoto two big mouths.

Hashimoto covered his face in astonishment, and then someone showed him the telegram. The telegram indicated that the southbound train was running as usual, but the northbound train, no one gave him an avoidance signal, but how was this possible? He launches the same information with 4 channels at the same time, how can the enemy possibly do something?

When Hashimoto was beaten, Keiji Suzuki was behind him, he was the only one who was calmer among the panicked military officers in the audience, and he waited for the telegram to pass in the hands of everyone, and then he took a look.

Hashimoto's plan, he was opposed at the time, because he knew the insidiousness of the enemy. According to Asano, communication technology could do everything in the future, and at that time, almost everyone in Japan had a portable communication tool that could be communicated at any time.

Asano never touched on specific technologies, but from his descriptions, radio communications in the future were completely different from those now. If 100 million people have portable communication equipment, it is impossible for everyone to occupy one channel, which is very unrealistic. So when Hashimoto proudly offered that he came up with the idea of sending messages on 4 channels at the same time, he felt that it was not so foolproof. But now he can't give any advice, he needs to get in touch with Kagezo Zhenzhao and inform the enemy that he may come back to conspire with Chu Tingchang. At present, Kagesa is busy laying out a new situation in the country, and it is impossible to come to Thailand, but I hope he can come up with a countermeasure.

In Chiang Mai City, Noda's artillery was fiercely returning fire, and he had the 150 artillery brigade specially allocated to him by the Southern Army, while the opponent seemed to have only 105 field artillery. Once the opponent starts a positional battle that consumes firepower and troops, Noda has a few bases, and his firepower does not suffer at all. But suddenly the supply of shells for heavy artillery stopped, while the fire on the enemy's side increased.

Chief Chu Tingchang replaced Tao Mingzhang's team and let his troops carry out earthwork in front of the enemy's position. The enemy's fire weakened, which increased the speed of work.

The 201st Division's action of digging trenches to approach the enemy increased the anxiety of the Japanese troops, and they repeatedly rushed out of their own trenches to try a decisive battle, and immediately fell into the net of fire. The 201st Division occupies all the commanding heights in the north and can clearly see all the enemy's movements, so the artillery fire came very timely.

At noon, Tao Mingzhang's 201st Division broke into the enemy's defense system first, and launched a hand-to-hand battle, although the cost was high, but it forced the enemy back step by step. The enemy could only tear down the east wall to make up the west wall, mobilize friendly and neighboring troops to support, and Zhou Youfu, who was dormant in the rear, saw through the intention, and his tank was inserted into the middle of the enemy's two troops with a clean intersperse, and penetrated 1 km behind the enemy's position. The Fifth Army's two completely different styles of troops took turns to attack, which made the opponent quite uncomfortable, and the entire system of the 14th Division showed signs of collapse.

Chu Tingchang got the news that the enemy railway was interrupted again by the United States, and it was two hours after Xu Chong's report, a US military plane flew over the scene and saw the derailment. But he had to feign surprise and call Stilwell back.

But how is this caused? He suspected that 419 had bypassed Malacca and rushed here, but Ma Qiang hadn't received the news yet, or was it really blessed by God?

In any case, the opportunity should not be missed. He transferred his 200 divisions to participate in the offensive. In addition, gather more than 40 Shermans from all 4 companies of your own side and wait for the enemy's 3rd Brigade to appear, so as to surprise Amano. He also never concentrated his tanks, and the dispersion of his forces has always been a characteristic of his troops. However, at present, it is the Japanese who have concentrated tanks, and if they want to play a big one, he is willing to accompany them to the end.

The 3rd Brigade, which was hiding in the rear, was forced to concentrate its forces and attack from the open openings of the flank positions, preparing to outflank the rear of Zhou Youfu's troops. Amano saw that this sortie was extremely dangerous, because it was impossible to have nothing in the enemy's rear, and the terrain of Chiang Mai, high in the north and low in the south, the enemy occupied all the commanding heights in the north, and any movement in the city could be discovered by the enemy in advance, which was what he feared the most. But the order from the top is urgent, and it is necessary to take a risk. So he made a plan for a quick attack, a quick retreat, out of a few thousand, and ordered artillery to fire * at several areas in order to interfere with the enemy's judgment.

A large group of tanks quickly attacked through the smoke, preparing to suddenly appear behind the flank of Zhou Youfu's mechanized troops and launch an attack.

The Japanese tanks wanted to find an opportunity to attack the enemy's weak underbelly, that is, those thin half-tracks and Stewart tanks, and in any case their tank firepower still had a slight advantage over Stewart. Before the sortie, Amano specially reminded Captain Hirose that the battle had to be fast, as he estimated that the enemy might bring in at least one company of Sherman tanks within an hour.

Amano's caution was still not enough, and he underestimated the adaptability of the Fifth Army, as well as the vindictiveness of Chu Tingchang.

In a way, the combat effectiveness of an army is actually its ability to adapt, Chu Tingchang quickly adapted to the characteristics of Amano, this man likes to flank one-way attacks because it is more stealthy than flanking them, and he moves quickly because he is afraid of Sherman tanks. Amano used * to cover before the attack, and he didn't confuse Chu Tingchang at all, and the purpose of Zhou Youfu's attack was to attack and save him. He didn't believe that the enemy would come out of an irrelevant place, and if Amano thought that such a trick would succeed, it must be said that Tenno was still too naïve.
