In the early days of the War of Resistance Against Japan, the Japanese army occupied a large area of the mainland, and the first goal of the Japanese army was to capture the coastal areas of the mainland in order to attack Nanjing, the seat of the National Government. Although the Japanese army captured Nanjing, the Nationalist government moved to Chongqing, the hinterland of the mainland, but despite this, the Japanese army still did not give up the plan to attack the seat of the citizen government, and Shaanxi, as a strategic place to open up the hinterland of the mainland, will naturally become the focus of the Japanese army's attack, but the Japanese army can not be attacked.
There were four reasons why the Japanese army could not conquer Shaanxi.
First, during the War of Resistance Against Japanese Aggression, the Japanese army's troop strength arrangements were comprehensively rolled out, in order to prevent the lone army from going deep and being attacked, the Japanese army basically advanced forward in many aspects, but if it wanted to capture Shaanxi, open up the hinterland of the mainland, and then attack Chongqing, it was necessary to send an army to go deep alone and lay down Shaanxi. In this way, if shaanxi is attacked, it will inevitably be sniped by the mainland army in the north and south directions, and the Japanese army will certainly suffer heavy casualties, which the Japanese military does not want to see.
Second, the terrain of Shaanxi is longitudinal and ravine, connected by mountains and rivers, and inconvenient transportation, which makes it difficult for the semi-mechanized troops of the Japanese army to advance. If the Japanese army chooses to enter Shaanxi to fight, their motorcycles and transport vehicles cannot play a role in the harsh terrain of Shaanxi, which will greatly increase the marching time.
At the same time, the terrain environment of Shaanxi's crisscrossed ravines is very convenient for sniping, and the semi-mechanized troops of the Japanese army are moving slowly in Shaanxi territory, which also provides a better opportunity for our army to snipe the Japanese army. Therefore, after the Japanese army enters Shaanxi, it will certainly encounter surprise attacks from time to time, and in the face of the high mountains and mountains of Shaanxi' terrain, they will not be able to effectively impact our army, so a small sniper is enough for the Japanese army to drink a pot.
This requires some people to ask, since this is the case, then the Japanese army chose to first put down Shaanxi, attack the southern and northern regions of Shaanxi, and after occupation, fully spread out the troops, and form a closed encirclement of Shaanxi, will it not be able to capture it? This brings us to the third issue.
Third, the Japanese army was selective in attacking mainland cities, and they would always invest a lot of troops in developed cities and resource-rich cities along the mainland coast, such as Shanghai and northeast China. At that time, Shaanxi was economically backward, resources were scarce, and the Japanese army invested too many troops in the southeast battlefield of the mainland, so it was still a little difficult to form a siege of Shaanxi.
On the other hand, in addition to attacking the mainland, the Japanese army also opened up a battlefield in Southeast Asia, hoping to launch an offensive from the Burmese region to the western regions such as Guangxi, Yunnan, and other regions of the mainland. It should be known that at that time, the materials provided by the United States to the Kuomintang troops were transported to the inland from here, and the Japanese army wanted to cut off the material transportation line of the Kuomintang troops, so it invested a large number of troops. However, in order to prevent this situation, the mainland immediately organized the Chinese Expeditionary Force to effectively attack Japan, and the Desire of the Japanese Army to invest a large number of troops to cut off the material transportation line of the Kuomintang army was also broken by the Mainland Expeditionary Force.
Secondly, because of the Japanese attack on Pearl Harbor and declared war on the United States, the United States and Japan opened up a new battlefield in the Pacific, and in order to resist the powerful United States at that time, Japan had to send a large number of troops and provide a large number of materials, which led to the increasing shortage of Japanese troops in China, and the supply of materials was delayed. At that time, there was a saying that I believed we were all familiar with: "The devil has entered the village!" In order to meet daily needs, the Japanese army began to sweep the rural areas of the mainland and other areas, scavenging for food and other supplies.
These circumstances led to their inability to further advance the army to the inland, and since they could not implement a comprehensive strategy and did not dare to go deep alone, how could they possibly capture Shaanxi?
Fourth, Shaanxi at that time was the base area of our army, and our army was stationed here for a long time, very familiar with the terrain and terrain, and most of them launched attacks in the form of guerrilla warfare. Under these circumstances, our army is depleting the japanese army's living strength little by little, and the Japanese army has not yet waited for a formal attack on Shaanxi, and it is estimated that the troops have been choked by us enough.
In addition, there is another aspect, and that is the solid level of Tongguan. As the first line of defense to open the gate of Shaanxi, Tongguan is easy to defend and difficult to attack, and the Japanese army will stop at nothing to lay down Tongguan. Since the Japanese army captured Taiyuan in 1937, the aircraft circling over Tongguan and the artillery in the city have not stopped, and the Japanese army wants to break through Tongguan by aircraft bombing and shelling, and it turns out that they think of Tongguan too simply. For 8 years, until the Japanese surrendered, Tongguan was not captured by them.
In general, it was too difficult for the Japanese army to capture Shaanxi, and even if they could fight it, they would pay a heavy price, and with the formation of the national war of resistance on the mainland and the joint efforts of the World Anti-Fascist Alliance, Japan's defeat was doomed.
