Compared with the Polish campaign in history, Germany is more prepared today, so the number of troops invested is also larger, the total number of front-line troops exceeds 1.2 million, if you add reserves, it will exceed 2 million, and Germany's weapons and equipment are far more advanced than when they invaded Poland in history, taking tanks as an example, not only the number of more than 3,500, but more than one-third of them are currently the first Panther tank. In the face of such an overwhelming liliang, the Polish army in this time and space is still difficult to resist even if they have long known the concept of "blitzkrieg". And when the million-strong Soviet Red Army also launched a full-scale offensive from the Eastern Front, there was no suspense about Poland's demise

On December 25, the German and Soviet armies met at the Bug River, and both armies were secretly alarmed by the strength of the other, so that the Soviet-German Non-Aggression Pact lasted longer than in history. Organized resistance in Poland continued until December 31, a day also considered the day of the fall of Poland, but the Polish government did not surrender to Germany or the Soviet Union, and a small number fled to Britain and France to form a government-in-exile, while the rest were mostly martyred

After the German invasion of Poland, Britain and France quickly declared war on it, but the attitudes of the two governments were very different. British Prime Minister Winston Churchill has always advocated being tough on Germany, so he hoped that the combined forces of the two countries would take advantage of the main German invasion of Poland and march on the German mainland to force it to withdraw from Poland. However, French Prime Minister Daladier, who had decisively betrayed the French Communist Party and thrown himself into the arms of the big capitalists not long ago, was frightened by the overwhelming offensive of the German army and did not dare to let the French army leave the strong Maginot Line. He refused to send troops on the grounds that he hoped that the Germans would continue to attack the Soviet Union eastward after gaining the passage.

Although Churchill was tough, he was not a reckless man, and naturally knew that without the assistance of the French, the limited number of British land forces alone would not be the opponent of the German army at all, so although he did not know how many times he scolded Daladier and France, he finally had to align with France and agree not to launch a ground attack on Germany for the time being, and in this way, Germany was given time to suppress the Polish people's resistance and prepare for the next attack

But. The British did not need to rely on the help of the French at sea. Although the British Royal Navy suffered heavy losses due to the unexpected destruction of the main forces of the two Far East Fleets, the British Royal Navy was still far stronger than the German Navy, even if only eighty percent of the ships remained, after Churchill ordered a naval blockade of Germany. Germany's maritime communications were soon completely cut off

The naval blockade of the British inflicted huge losses on Germany. Fortunately, after the improvement of Soviet-German relations, the Soviet Union was willing to provide them with land access. So that the secret cooperation between China and Germany can still continue, but the Soviet Union is a potential enemy of the two countries after all, in order to avoid leaking too many secrets. The two countries had to end scientific and technological exchanges ahead of schedule, but fortunately, China's rare minerals can continue to be sold to Germany, but unlike in the past, when science and technology could be exchanged for resources, Germany could only pay hard currency to buy in the future, but fortunately, after occupying Poland, Germany grabbed a lot, and Germany could still afford to pay, at least temporarily

In addition, Mustache's original wishful thinking of continuing to "trafficking in human beings" as he had done after the occupation of the Czech Republic was also cancelled, and he had to resort to concentration camps against the Polish rebels, but the Jews who hated the disease were the most imprisoned in it

It was a bad feeling to be strangled, and Germany soon sent several German-class armored ships (pocket battleships) out to sea to break the diplomatic battle, hoping to lure the main force of the British Royal Navy away. On the other hand, although the French naively hoped that the Germans would start a war with the Soviet Union, they did not dare to slack off on the defense of their country, considering that North Africa was no matter how important it was, it was not as important as the mainland, Daladier decided to withdraw part of the army from North Africa, leaving enough troops to keep the big cities and lines of communication, and the French navy, which had nothing to do for the time being, was sent to secure the most elite coastal zone in the North African colonies. But before the French government's order was issued, Daladier received a shocking news, "The Chinese have attacked?" Vietnam? From the sea? ”

Hu Weidong has always liked to surprise with his troops, but this time he chose to have three marines under the cover of a naval fleet land on the coast of South Vietnam and attack Saigon, the most important city in French Indochina, which was not a military adventure.

Since the main force of the Second Far East Fleet was annihilated by China's naval and air forces, although the British still have some ships in Southeast Asia, they no longer dare to leave the Singapore naval base too far, which makes the Chinese navy, although not strong, easily gain sea supremacy in the northern and central waters of the South China Sea. On the premise of having sea supremacy, it is naturally easy for the Chinese marines to land on the beach, and at the same time, because the French never thought that the Chinese army would choose to attack from the sea, it is natural to deploy most of their forces north of the Red River.

And Hu Weidong's choice of this offensive route also refers to many lessons in history, because Vietnam has always had an anti-Han tradition since it became independent, so it has been conquered by the Central Plains Dynasty many times in later history, but these wars ended in Vietnam without exception, even the Yuan Empire, which is incomparably strong, can not help this small power in southern Xinjiang, is it really so difficult for the Vietnamese to conquer?

But the later colonial aggression of the French is enough to show that Vietnam is actually not so difficult to deal with, if it were not for the Chinese Black Flag Army to help them withstand for a while, I am afraid that Vietnam will be annexed by France early. The Vietnamese were vulnerable to the French, and although there were reasons why their weapons and equipment and army organization were inferior to the enemy, Hu Weidong keenly saw a point that has been overlooked by many historians, that is, unlike China, which attacked Vietnam from north to south, the French invaded Vietnam from south to north

Hu Weidong also discussed this with Taizu, who was well versed in history, and Zuihou finally came to a conclusion. It turned out that the northern part of Vietnam was mountainous and poor, and if the enemy came from the north, the existence of these mountainous areas on the one hand increased the difficulty of the attack, and on the other hand, even if the attacker occupied part of the mountainous area, the economic gains would inevitably outweigh the losses, and at the same time, the elongation of the battle line increased the pressure on logistics and supplies (to be continued......
