The Isogu cluster was the first to complete the assembly, and the basic sequence included the 112th Division that boarded from Dalian, the 122nd Division that landed from Nampo to Changyuan in North Korea, the 134th Division that landed at Yingkou, and the 80th Brigade that landed on Dandong. All of these troops did not have time to wait for their full strength and unload their heavy weapons, and they began the battle with urgency. This was, of course, an order given by Sakagaki's last telephone call with Isoya.

Itagaki himself set out from the West Palace, and the troops under his command were even less, and the main forces were the 1st Mobile Brigade and the 63rd Division, as well as some engineering units. Itagaki decided to start ahead of schedule because he realized that this battle must not be evenly matched, and the enemy must be defeated quickly.

Of course, he is not blind and unscrupulous, but he has the right time, and if he continues to delay, his offensive intentions may be seen through by the enemy and he will be defensive. In addition, he already has a new set of tactics for continuous attacks along the Mekong River, which is supporting his rapid attack. He wanted to quickly defeat Zhou Youfu, and then turn around and eliminate Huang Tianyang. During this period, the technical preparations for the air-dropped nuclear bomb were probably about the same.

To put it simply, he wants to use the transportation capacity of the Mekong River to devote the troops and supplies that arrive later to the front line in greater depth, and if he only lands along the coast, the troops that arrive later will inevitably stay away from the battlefield that continues to extend westward. He wanted to take advantage of the Mekong Valley's extensive shipping routes to give full play to his maneuverability and fleet firepower, so as to offset the mobility and firepower of Zhou Youfu's tank troops. If he gave up these advantages, he thought it would be difficult for him to eat Fu Zhouxuan. The river network zone was obviously more advantageous to the Japanese army, which had naval superiority, and not to the Chu Ting Chang Army, which consisted of pure ground forces. Of course, he had two trump cards in his hands, one of which was the 1st Mobile Brigade, and the other was a newly improved anti-tank *. The new * can be fired from vehicles, the firing range has been increased to 2 km, and in addition to attacking opposing vehicles, it is also possible to attack positions.

Zhou Youfu had been waiting for Shangfeng's counterattack order, but he didn't wait until the enemy's assembly was completed.

He had never doubted the command of Pavilion Chief Chu, but this time, Lao Zhou was a little complaining. He never went to a regular military school, and he relied on his own groping to fight. The only trick is to keep the enemy in a vicious circle of rushing/retreating/hasty defense/continuing to collapse with a sudden attack. However, during the month-long sit-in, Chu Dinh Chang only tinkered in the rear, but did not launch an attack on the vulnerable enemy troops ashore, and watched the 112th Division from Da Nang to Tri Phi go all the way north, make peace with the remnants of Hue, and then join forces with the 80th Brigade that landed from Haiphong and used the railway to go south, and finally became the climate.

During this period, any surprise attack could drive the enemy who had not gained a foothold into the sea, or at least destroy their stockpile near the landing site, and then carry out repeated attacks, so that the enemy could not gather his forces until he was exhausted. He was confident that his troops could complete such a short offensive without being found by the enemy to use nuclear bombs, but Chu Tingchang never let him go, but let him focus on building rear roads and pontoon bridges, and seemed to have made up his mind to retreat.

After the Isogu cluster completed the initial assembly, began a tentative offensive, Chu Tingchang also ordered Zhou Youfu's 43rd Group Army not to implement the best at rapid detour behind the enemy, but to carry out the position that the troops are not good at to hold, and now the enemy finally leaked out of the fangs, gathered two ways to attack, and the division of troops and defense will obviously fall into a war of attrition, and Chu Tingchang gave him permission to retreat, it seems that he is constantly building bridges on the rear river, Chu Tingchang has long been prepared to retreat, he wants to withdraw to the Vietnam-Cambodia border, although the depth of Vietnam is not large, and it can be fought back in a few days, but Commander Chu's fear of *, so he retreated tactically, is really a bit too much. Zhou Youfu himself has personally seen the power that sweeps through everything, and even the deafness has only recently been raised, but he thinks that he can actually deal with it, as long as Chu Tingchang's hexagram can be more timely.

The South Road Sakagaki cluster was very violent, but fortunately, the information of the Vietminh was relatively accurate, and Lao Zhou was able to use his mobile combat skills to a limited extent, constantly killing and wounding the enemy.

Zhou Youfu could clearly see the enemy's intention from the map, that is, to launch a pincer offensive from the north and south to surround him. As early as in the operations in Chinese mainland, the Japanese army repeatedly tried to outflank the two ways to launch an offensive and eliminate the effective forces of the national army, but they never succeeded because of the lack of mechanized strength, and finally either fought a nonchalant war of attrition, or let the national army slip through the gaps. This time seems to be no exception, the enemy army is like a clumsy python, slowly coming along the Mekong River.

Even if there were a large number of transport ships that gave the enemy a superficial advantage of fast troop transport, the lack of landing ships was the biggest drawback, and the cargo ships unloaded troops, required complex maneuvers (soldiers needed to climb from transfer nets to sampans), and could not unload heavy weapons.

Zhou Youfu felt that it was delusional for the enemy to surround him, of course, it was also true that the giant python could always entangle animals far more flexible than himself. Viet Minh's intelligence indicated that tanks had appeared in the rear of Sakagaki, but Zhou Youfu judged that perhaps it was just that, as usual, the tanks were just an embellishment of the Japanese infantry rather than a separate main force.

His battalion and company-level composite units, from time to time, maneuvered to the rear of the enemy, striking at the baggage troops and the slowly moving transport ships in the river, and repeatedly handed, the 75mm guns carried by the half-track could effectively destroy the enemy's cargo ships. But the enemy also seemed to be prepared, carrying quite a few light anti-tank weapons (*), and even some cargo ships were equipped with such weapons. These weapons caused some losses of Zhou Youfu's troops.

In previous campaigns, the Japanese army had been engaged*, but the results were not ideal, the shortcomings were pride, the speed was too slow, and the turning rudder efficiency caused by low speed was not good, and the new batch underwent some improvements. These weapons made Lao Zhou suffer a little.

Tao Mingzhang conscientiously wrote about the examples of encounters with the enemy's anti-tanks, and conscientiously summed up the lessons and strategies. Although Zhou Youfu looked down on Tao Mingzhang in his heart, he carefully looked at these internal references about the enemy's new weapons.

Tao Mingzhang summed up three ways to deal with the enemy's anti-tank*, one of which is smoke. He picked up a few unexploded bombs, saw the copper wires connected to the back, and judged that it was manipulated by the rear personnel, so at a long distance, smoke should be released to make the sighter lose his accuracy. This trick always works.

The second method is to maneuver the vehicle quickly, especially when * is close and has no time to release the smoke when it is too quick to make a quick turn, which will make the enemy* unable to keep up. This kind of thing is quite clumsy, once the turn is too big, it is easy to lose control, most of the time it loses lift and falls to the ground, and there are also tears off the control line and flies around. However, Zhou Youfu's troops found that they might be able to get rid of the turn during the battle, but they did not find that the enemy's ammunition fell to the ground or flew indiscriminately. Apparently the enemy improved the launch and maneuvering.

The third way is to meet the attack with frontal armor in the worst-case scenario. However, this experience was still ineffective, and the Japanese army improved the hollow-charge warhead, so that the jet armor penetration depth reached more than 60 mm, and the previous experience was no longer effective.

Sakagaki is waiting for his opponent to keep coming, so that he can entangle his opponent. He knew that his strategic intentions could not be hidden, and the enemy could see it long ago, and the only thing that could confuse the opponent was the unhurried advance speed of his troops, which would make the enemy who had the advantage of mobility feel that it was not a big problem, but he kept his last hand, which was the 1st Mobile Brigade, which was the only fully equipped unit in the Japanese army in Vietnam.

The sluggish, cold-blooded serpent hides the last sharp blow, and those prey that are alive and kicking always die from the enemy.

Lin Xiuxuan's reconnaissance unit found traces of the enemy's tank units from time to time, usually Viet Minh sightings and tracks on the ground, but it was too late to verify the above information, and there was no information on the size of the enemy's troops, and the lack of no one made the intelligence reduce by eighty percent, and the lack of radio monitoring made the remaining intelligence sources discounted. Lin's intelligence team could only use night vision devices to cross enemy rears at night, but it was difficult to see the tracks on the ground and the tank paint at night. This allowed the enemy's machinations to be hidden.

Zhou Youfu's troops repeatedly attacked the flanks of the enemy along the river, and although they continued to annihilate small groups of enemies, they failed to slow down the enemy. Now it was time for Sakagaki to change his pace and surprise his opponent, he sent a plane to drop an order to Isogu north of Dalat, and finally coordinated the main points and time of the attack, and launched the attack.

Major General Iwamoto's mobile brigade suddenly emerged from the rear of the Japanese army, and the purpose of this attack was to seize the bridge and key obstacles behind Zhou Youfu.

For the inexperienced Japanese tank forces, the missions were unavoidable, but there was a great ingenuity hidden here.

Iwamoto's 1st Wing and the following tank task force used 35 Stewart tanks captured from the Henan battlefield, and the tank livery still used the blue sky and white sun, which was completed after the East India was unloaded, and was not bothered to modify after it was delivered to Tang Enbo, almost exactly the same as the Chu Ting Chang. In the Central Plains fiasco four months ago, most of the tanks ran out of fuel and had to be abandoned. In order not to fall into the hands of the enemy, the commander's final order was to say that the tanks would sink into the Yellow River, and such an order would obviously make the driver take too much risk, so the order was carried out in disobedience, and finally these tanks in the shallows during the dry period were dragged ashore by Gangmura Ningji without much effort.

The chariots had been disembarked from Saigon under tarpaulins, and the Viet Minh agents were unrecognizable when they watched from a kilometer away. Now it's time to put it to the test. Of course, in addition to the original American tanks, Iwamoto's troops were also accompanied by many veterans who could speak Chinese. The 1st Mobile Brigade is stationed in the northeast all year round, and many of them speak Chinese perfectly, even faster than most of the southern soldiers of Chu Tingchang. On the eve of the attack, they began to eavesdrop on the phone calls of Zhou Youfu's troops while secretly approaching the front line, and also established some radio communication to learn the most advantageous position to penetrate through the gaps of the Chinese army.

Before sunrise, the task force secretly drove away from the Japanese line and advanced towards the set goal. They will get into the gap between Zhou Youfu and He Bisheng, avoid too much contact, and implement the plan, but some key information, which did not appear in the conversation with the Chinese tankmen, is that Zhou Youfu's engineering unit has just laid a minefield in the gap.
