This time, the Japanese's vanguards were the 1st Division, the 8th Division, the 9th Division and the 5th Division, the 6th Division, the 7th Division, and the 6th Division, the 7th Division, and the six A-level divisions transported from the local area some time ago. This was just the vanguards passing through the border. More than 800,000 Japanese were gathered in the three eastern provinces.

The Japanese's strategic intentions are very clear, and it is impossible to drag them down. The Japanese's strategic steps are very simple. The army went south along the railway road to Dingbeiping, Dingbeiping, Dingzhou, Dingxuzhou, Dingzhou, and Dingzhong, and Dingzhong, and Dingzhong, ending the war in the first battle, Dingbeiping, Dingzhou, and Dingzhong, and Dingzhong, and Dingzhong, and Dingzhong, ending the war in the fourth battle.

The Japanese felt everything went smoothly in the first two days of marching. Often, the opponent's cavalry ran away from afar and saw the power of the Kwantung Army. There was nothing except the occasional mines on the road. But after two days, the Japanese couldn't hold back. The march was too smooth. The casualties were less than three digits, and they were far from the number of mines encountered when they marched in the pass. Moreover, the people in the village along the way could not see any of them, and the pig, cattle, sheep, chicken and flower girls were not like this.

A month has been enough for the Ministry of Military Affairs of Peking to play the scorched earth war. Originally, Rehe was ruined by the Japanese two years ago, and they died and fled, and it was not an exaggeration to say that nine out of ten families were empty. In the past two years, those who were thinking about the houses and fields had retreated with the front-line garrisons. They knew what the Japanese were like when they came. Except for a small number of whom were willing to stay in Chengde as a tyrant to help defend the city, the remaining Rehe people took their families and retreated to the Yanqing Shunyi area in the suburbs of Beijing.

The Japanese did not understand, but Jin Batian knew one thing. The front line was arranged according to the ideas of the Nanjing General Staff Headquarters from the beginning. The combat idea was eight words, luring the enemy into depth, gathering and annihilation. The entire Three North National Defense Line was not a long snake formation like the Maginot Line, but a three-dimensional and deep national defense line fortification.

It would be impossible to use the fortifications of the front national defense line to block more than 100,000 Japanese devils, but I am afraid that the Japanese will not be willing to chew on the hills. The Japanese devils have no pit at all. The border is so long, even if you are the iron barrels run by Chahar, I will take a detour to attack Shanxi and Shaanxi. So in order to maximize the interests of the fortifications of the national defense line at one time, the Ministry of Military Affairs of Peking has formulated a plan to use Chengde as bait to attract the largest number of Japanese devils to gather and annihilate them. In order to make the Japanese's plan to use war to support wars and extend their supply lines, the scorched earth anti-Japanese strategy is necessary.

The Japanese were passing by many observation posts in the national defense fortifications along the way, but the top did not order the attack, and the bottom was still holding it back.

After the Japanese invaded Rehe territory, Jin Batian breathed a sigh of relief. It seemed that the confidentiality work of the national defense line was done well. Before the Japanese came, Jin Batian was afraid that the national defense line project would leak news. The Ministry of Military Affairs also issued strict orders, and the troops entering the national defense line fortifications were allowed to enter and not leave before the end of the battle.

There is only one main road with countless fortifications in the national defense line that is hundreds of kilometers long and has countless fortifications. Each fortification represents a position. The passages and fortifications are hung with biogas lamps that are turned on for 24 hours. Jin Batian is so careful in the toilets here, of course, need to build biogas pools instead of using electric lights. Before each army enters, the signs they want to enter have already been hung in advance. The person who hangs the signs as required will come out later than the army enters.

On July 1st, Jin Batian got the news of the Japanese's advance and gathered more than 300 people under his command on radio. Jin Batian said, "There is a tough battle here in Chengde. I want to hand over a hundred 150mm mortars to you to send to the Chengde front line. You know how many shells you can bring. Even if Chengde can't defend it in the end, I will leave you a way out. How about it, will anyone not go?"

Everyone stepped forward and said in unison: "No."

There has not been a war in the past two years, so there is no income. Jin Batian only gave a lieutenant-level national crisis salary of 30 yuan, which has long been a mercenary. Whenever he has time, he is not only the eight major hutongs but also the eight major hutongs. He is called "General Cai" and "As a lieutenant-level national crisis," of course, in order to learn from General Cai, a lieutenant-level national crisis salary of 30 yuan is far from enough. In the past two years, everyone has become accustomed to not being able to make ends meet. He sees that he has the opportunity to make money, and naturally he will not let go of it.

"Okay, **Even there are other than me, get in the bus and set off."

There are 150 ten-wheeled trucks in a row, which is also a little help from Jin Batian to Chengde. After all, the vanguard of the Japanese have five A-level divisions of 180,000 troops. Can the Sichuan Army defend Chengde be able to defend Chengde? Now there is no clue. The only way to defend Chengde is that Chengde is not very different from the plan of the Beijing Military and Political Department. Chengde is in the middle of the Rehe River, and there are underground fortifications of the national defense line around the southeast, west and north. The significance of guarding Chengde is to attract the largest number of Japanese soldiers to enter the encirclement in Rehe. As the saying goes, how can a tiger be obtained without entering the tiger's den? Can a Japanese be deceived without spending some capital?

On the 150 ten-wheeled trucks, in addition to 100 150 mm mortars, there are also a large number of mortar shells, as well as canned supplies and other supplies.

The Japanese marched to Chengde for a few days and did not attack immediately. The first thing they thought was to give Chengde defenders a little color to see the morale of the defenders. So sixty Japanese fighters and forty-eight light bombers flew over Chengde from Shenyang Airport.

"The Japanese aircraft group took off from Shenyang, with the target of the southwest. About one hundred aircraft."

Song Ziwen's determination is very simple. If you send one, I will be able to stop you: "Order the 1st Division of the Peking Air Force, one, two, three, and four fighter brigades, all targeted the Japanese troops and aircraft."

At this time, the first division of the Peking Air Force had six aircraft, two in groups. One flight squadron had three squadrons and eighteen aircraft, and one flight squadron had three squadrons and fifty-four aircraft. The first division of the Peking Air Force had nine fighter brigades, three bomber brigades and two transport aircraft brigades. The entire division had more than 1,000 pilots and more than 6,000 ground staff. Most of the main technical personnel came from the Northeast Army Air Force and Northeast Aviation School, the former poaching team.

The Japanese did not know that Jin Batian had already dismantled two of the carrier-based radars and sold them to the Ministry of Military Affairs of Peking. (The Japanese don’t know what radar is) Not long after the Japanese aircraft took off in Shenyang, the aircraft from the Ministry of Military Affairs of Peking also took off. The P26 fighter was still not outdated at this time, at least it was much stronger than the Japanese biplane and could also hang two small bombs.

Just as the Japanese were waiting for their planes to blow up the defense line (the order of defending the city is the highlands outside the city, the city gates, the city walls, and the street fighting), the sky was buzzing, and there were countless aircraft forming several formations in the air flying from the south. The officers and soldiers on the defense line were holding telescopes and saw the paint on the plane and shouting: "Our plane."

Then thousands of people shouted in and out of the city: "Our plane."

The Japanese knew that the shouts from the opposite side and the sound of planes in the air were vaguely heard, and the Japanese knew that it was not good. The troops immediately ordered the evacuation of air defense. However, the people could not escape the artillery. Small bombs of forty-five kilograms fell from high altitude on the Japanese artillery positions. This bomb with a power of more than 105 howitzers. A bomb fell by hundreds of square meters nearby, and the guns were often flattened to the ground by the shock waves of the bombs, and the artillery naturally dispersed.

The plane later left the bomb still on the Japanese cars and tanks. When the plane arrived at the end had no valuable target, it threw the bomb into a place with a large number of Japanese people.

After four hundred bombs were thrown away, more than two hundred planes left to find the bad luck of the Japanese plane. The machine gun bullets were left for the Japanese plane.
