For Vietnam, the loss of the mountainous areas eased the financial burden and allowed them to organize stronger resistance. The enemy is getting weaker and weaker, and the Vietnamese army is getting stronger and stronger, and the tropical disease with a high mortality rate in ancient times is more lethal to the enemy army in the north than the Vietnamese army itself, so it is not surprising that ancient China has never been able to conquer Vietnam, in fact, the situation in North Korea is similar, but North Korea does not have tropical disease to help, so its performance is not as strong as Vietnam

If you attack from the south to the north, the situation is completely different, first of all, southern Vietnam is an easy and difficult to defend plain, and the foreign enemy can take it at a relatively small cost; At the same time, South Vietnam is far richer than the North, and grain production accounts for more than half of Vietnam, so after losing the South, Vietnam's money and food will not be enough to maintain its original army size, and the Vietnamese army will only fight weaker and weaker, on the contrary, the enemy army can make up for the loss of war by fighting the war, and at the same time, the huge economic benefits obtained from the occupation of South Vietnam can also strengthen their will to war, so that its upper echelons will resolutely carry out the war to the end, so it is not surprising that Vietnam was destroyed by the French army in the first place.

Therefore, after Hu Weidong discovered that the Chinese navy, which was still not strong, could seize sea control over most of the South China Sea, he immediately came up with the idea of following the example of the French army in attacking Vietnam from the south to the north. In a sense, this can be regarded as "treating others the way they do." "That's it

After the PLA landed in southern Vietnam, the French troops in the north hurriedly withdrew south, but the mountainous terrain was difficult to travel, and the road traffic was seriously damaged by the Chinese Air Force. It must be explained that although the various new aircraft developed by the French army before and after World War II in history are unknown in later generations, their performance is first-class, and the army can only be blamed for worshipping too quickly. The government capitulated so early again. But. The number of aircraft deployed by the French army in Asia cannot be compared with the Chinese Air Force fighting in the neighboring mainland, and the increasing number of J-1 equipment of the Chinese Air Force is like a cheating existence for the fighters in service in various countries during this period, after the super ace Zhong Ming changed to the J-1. In the first month of the war alone, hundreds of French planes were shot down. And his landline did not suffer any serious trauma. Undoubtedly the best proof of this

It is worth mentioning that the J-1 is not only fast, has a high ceiling, but also has excellent horizontal maneuverability, and its protection is also extremely good. Because the epoxy-hardened paulownia wood was as hard as steel, and the French aircraft were not equipped with large-caliber cannons, they could not do effective damage unless they hit at close range. Therefore, the losses of the J-1 in air combat are very small, if you do not count the results of the anti-aircraft guns, for every J-1 shot down by the French army, they will lose more than 50 aircraft, how can this be fought?

While the French army was retreating southward with difficulty, the more than 50,000 elite soldiers of the Chinese Marine Corps rushed north along the line of communication by car and even armored vehicles, sweeping away the scattered French troops along the way, and seizing the opportunity of the main force of the French army to withdraw to Hanoi before they had time, with the strong fire support provided by the destroyers and frigates that sailed up the river into the Red River, they immediately launched a fierce attack on the second largest city in Vietnam. But in the end, it was still unable to resist the marines who were far superior to the PLA in terms of both numbers and combat effectiveness, and it was only three days before the entire city of Hanoi was liberated

After learning that Hanoi had fallen and the lower reaches of the Red River had been blockaded by Chinese warships, the remaining French officers and soldiers were all dead, and with the only remaining piece of territory, they could not feed the 300,000 French troops north of the Red River in any case, and even if the PLA did not attack, most of them would starve to death. The desperate French first tried to force their way across the Red River, but were bombarded by the Chinese navy's naval shells. He then returned north to try to enter China to get supplies, but was bled by Hu Weidong's strong defensive line

The two failed attempts left the French with more than 100,000 casualties and little ammunition, while the Chinese army, which had suffered only a few thousand casualties, still maintained an offensive capability of almost 10 percent. The remnants of the French army, which did not dare to fight the PLA any longer, had to retreat westward into Laos, hoping to divert to Thailand to get food. But the French army has forgotten a very fatal point, all the way is mountainous, and when it comes to mountain warfare, who is the opponent of the PLA in the world? What is especially terrible is that the speed of the PLA's mountain march is more than twice as fast as that of the French army, which cannot be fought and defeated, and there are people who continue to lose their lives because of various poisonous insects and beasts in the tropical rainforest along the way, and the morale of the French army continues to decline along the way, and Zuihou finally completely collapses

By the end of January 1941, the Chinese army had basically liberated most of the French Indochina colony, during which more than 70,000 French soldiers had been killed, more than 200,000 prisoners had been captured, and another 40,000 or 50,000 were missing in the vast primeval mountains and forests

In the process of liberating the French colonies in Southeast Asia, China also sacrificed more than 10,000 commanders and fighters, at least half of whom died not from the guns of the French army, but because of tropical diseases and the poisonous insects and snakes unique to the tropical rainforest.

In any case, the PLA's attack on the French colonies was a good one, but it wasn't here that really started the first move. Hu Weidong was not sure how much he could help China until he heard from Kerim, so he devised another plan, just in case, to directly threaten India, which was vital to Britain, in order to force a voluntary peace suture. At this time, Fang Yongle's Tibetan military subdivision had already converted many Gurkha soldiers captured last time, so Hu Weidong ordered Fang Yongle to lead his army out of the Sikkim Pass, and under the leadership of these foreign "liberation fighters", liberate Nepal, an important source of troops for the British Indian colonial army, on the one hand, weaken the British army, and on the other hand, directly threaten Delhi and put pressure on the British government.

Due to the continuous increase of troops during the confrontation, the total number of British troops in India at this time was at least 150,000, even if Burma was not counted, and even more than 300,000 if the colonial troops were included. In comparison, Fang Yongle's field troops are only more than 30,000 people, which is too few, and when fighting in the southern foothills of the Himalayas, the British still have absolute air supremacy, but Hu Weidong is full of confidence in this former love general, and Fang Yongle did not disappoint him (to be continued......
