On March 8, after the independent 77th division took the four forks, the whole army marched along the highway towards Chengde, but was stubbornly blocked by the second division in Hanjiadian, and the two sides fought fiercely for a day and night, and the independent 77th division could not advance an inch, and the troops suffered heavy casualties.

Hanjiadian is the gateway to Chengde, where the Japanese army established a stronghold as early as 35 years. During the first Battle of Saibei, when the main force of Han Yunhua's department retreated, it took the road from Hanjiadian to Guyuan, so afterwards the Japanese army established more than ten pillboxes along the mountain here. Since the largest caliber artillery of the 77th Independent Division was only 75mm, these reinforced concrete fortifications did not work at all, and the battle situation was temporarily deadlocked.

At the same time, the two regiments of the 2nd Assault Brigade of the 300th Division were successfully reunited with the northbound detachment led by Commander Nie (Rong Zhen) in Wei County, and Commander Nie also smoothly took over the command of the southern front. However, because the main field wing of the 14th Division of the Japanese Army was stationed in Wei County, and Wei County was an important military town in Jizhong, the Japanese army built a large number of fortifications after occupying Wei County, so the southward detachment besieged the county seat of Wei County for two days and one night and still did not take it, and the troops suffered heavy casualties.

On March 9, the battle situation on the southern front took the first turn, and Commander Nie, with the cooperation of the underground party comrades in the city of Wei County, attacked the headquarters of the Hashida Wing. Seriously wounded the Captain of the Hashida's Wing, Taro Hashida, caused a temporary confusion in the front-line command of the Japanese army. The 2nd Assault Brigade seized the opportunity to launch a surprise attack on the Japanese army, and after three hours of fierce fighting, the Japanese army was finally driven out of the county seat of Ulxian.

However, the main force of the Hashida United was still alive, and under the command of Deputy Wing Commander Sakata Nakasa, it was withdrawn to a small town 30 kilometers south of Ul County and waited for reinforcements.

On the periphery of the southern battlefield, the Japanese Fifth Division and the 8th and 9th Independent Mixed Brigades were rushing to Weixian for reinforcements, and in order to prevent Han Yunhua's headquarters from fleeing northward, the headquarters of the Japanese North China Front dispatched more than 150 planes and dropped a brigade of paratroopers in the mountainous area leading from Xinghe to Tianzhen on the morning of 9 July, completely cutting off the communication links between Han Yunhua's headquarters and the Inner Mongolia Military Region.

On the morning of 10 March, the headquarters of the North China Front held a news conference in Beiping, at which Major General Kunisaki, spokesman for the North China Front, declared that the main force of Han Yunhua's headquarters of the Eighth Route Army, which was extremely arrogant, had been surrounded by the Imperial Japanese Army on the line of Tianzhen and Yangyuan, and that the main force of the North China Front of the Great Japanese Empire was now making every effort to encircle and annihilate this unit, and a breakthrough had been made. In view of the threat posed by the Korean Ministry to the Great Japanese Empire and the huge losses caused, the Imperial Army of Sonyam did not accept the surrender of the Korean Army.

The North China Front can be said to have played this trick quite cleverly, and as soon as the news came out, the whole country was shaken. The eyes of the whole country are focused on the small place of Yangyuan, and the headquarters of the Central Committee and the Eighth Route Army have been telegraphed continuously by the headquarters of the Inner Mongolia Military Region, and both the national government authorities and the democratic parties are concerned about the safety of Han Yunhua's department.

At the beginning, after receiving the telegram from the headquarters of the Eighth Route Army, Han Yunhua was still a little puzzled, what kind of medicine did the two bosses take, and why did they start to retreat. Later, Han Yunhua, who knew the truth of the matter, was a little crying and laughing, isn't it just a paratrooper brigade? To put it bluntly, the Japanese paratrooper brigade is an infantry brigade that is not satisfied, and its combat effectiveness is not necessarily as strong as that of a field brigade of the Japanese army. With such a paratrooper brigade, he wanted to cut off the pace of Han Yunhua's troops going north, and General Bin Shanyuan could think that as long as Han Yunhua was willing, he could defeat this paratrooper brigade by putting together a special combat team. You must know that the paratroopers of the Japanese army are notoriously rubbish in the world, and their combat capabilities are not even satisfactory, and they are called the worst and stupidest paratroopers in the world by their teachers, the German paratrooper instructors. The Japanese paratroopers performed very badly in several battles during their stay in China, so Han Yunhua did not think that the Japanese encirclement was much of a threat to the more than 50,000 troops under his command.

But now the domestic public opinion is very unfavorable to **, and they have asked the headquarters of the Eighth Route Army to send a large army to rescue Han Yunhua's department, so at this time Han Yunhua had to take a position on this. At 8:10 p.m. on March 10, exactly 12 hours after the Japanese army released the news, Han Yunhua's headquarters issued a clear telegram on the radio: "The Chinese Civil Affairs Committee, the Central Committee, the Eighth Route Army Headquarters, the people of the whole country, all friendly troops, and all foreign friends who love and sympathize with China's suffering: Oriental clowns are grandiose and unashamed of their wolf ambitions, and they want to peep at our Chinese artifact. The country that threatens the peace of the world, and the country that will suffer at that time is by no means the Republic of China, and England, the United States, France, and the Red Soviet Union are not spared. Today, I heard that Dongyang children actually spoke wildly, wanting to encircle and annihilate our troops in Tian, Yang, and Wei counties. What is even more ridiculous is that the dignified North China Front Command actually said that it would not allow our army to surrender, but I remind His Excellency Binshan Yuan that it is still too early to make a presumptuous assertion at this time, and what happened to His Excellency Terauchi Shouichi is a lesson for you. Since Your Excellency wants to take the noble heads of tens of thousands of soldiers of our army and leave no chance of life, our troops will not spare any hand in this battle, and all the captured captives of your country will be hanged, and as for the expectation of His Excellency Binshan Yuan, it is not expected that it will be realized, so let us wait and see.........

As soon as this plain-code telegram without a title was issued, it aroused wide repercussions at home and abroad. A few hours ago, the headquarters of the Japanese North China Front showed the reporters attending the meeting some evidence that Han Yunhua's headquarters had been surrounded, which made the entire Chinese nation worry about the safety of this legendary general. The whole thing suddenly became confusing, and they were all speculating whether this was the end of Han Yunhua's strong crossbow, the dead duck's mouth was stiff, or there was a backup move.

This is tantamount to a letter of declaration of war, and it is a war letter issued to the North China Front Army in front of the whole world, and General Binshan Yuan has to accept it. But this is the original intention of Bin Shanyuan to hold that press conference, since Han Yunhua took the initiative to challenge, then what reason did he have to refuse. Immediately, a sternly worded order reached the provisional headquarters of the 5th Division, ordering Lieutenant General Toshiyoshi Ando to settle the battle within five days.

Lieutenant General Toshiyoshi Ando was not a dry eater, and immediately sent a telegram to Major General Yoshito Takagi and Major General Yamashita Fumi, commanders of the Eastern and Western Route Army, ordering them to meet at Tianzhen within two days, and then quickly move south to join forces with the Fifth Division under Yangyuan Castle.

The wish is good, but the reality is cruel, the progress of the three-way army is extremely slow, and it is stubbornly blocked by Han Yunhua's troops in Yanggao and Huai'an respectively. Not to mention the heavy casualties of the troops, they were not allowed to advance an inch, and the main force led by himself was pulled by Commander Nie to Huajialing, a mountainous area north of Wei County, to fight and consume. Commander Nie occupied the geographical advantage of the right position, and also built strong fortifications, although he took the initiative to abandon the county seat of Weixian, but the defense of the troops did not decline in the slightest. In addition, the supply replenishment site of Nie's headquarters was in Yangyuan, less than 80 kilometers away from the defensive position on the southern front, while the Japanese army's supply station was in Laiyuan County, hundreds of miles away. Therefore, after three days and three nights of fighting, although Commander Nie's troops suffered heavy losses, the losses of the Japanese army were also quite small, and what was even more terrifying was that the spirit of the troops had dropped a lot, and it was less than two days since the five days given by His Excellency the commander, and Lieutenant General Ando Toshiyoshi was extremely anxious.

The battle on the southern front fell into a stalemate, and no one could help anyone in a short period of time, although from the overall point of view, the Japanese army still had the advantage, but Han Yunhua's department was not without a chance to turn the tables. However, Han Yunhua's order to the commanders of each unit was quite strange, on the premise of ensuring casualties, try to delay the Japanese troops in front of him, and the time must be more than five days.

Lieutenant General Yasui Toji, commander of the garrison in eastern Hebei, did not expect that the attack of the Independent 77th Division would be so sharp, and under the light enemy, the Sichakou defense line was defeated by the Independent 77th Division in one night, and the 7,000 defenders fled back less than 4,000, and most of them were wounded of varying degrees of severity. Fortunately, the bunker group in Hanjiadian played a big role, and a wing was stunned to block the independent 77th Division for three days and three nights, causing great troop losses to the independent 77th division.

According to Lieutenant General Yasui Toji's prediction, as long as the troops, weapons and ammunition are sufficient, the Hanjiadian position can become the western gate of the entire eastern Hebei. During this time, he also investigated clearly, and there were only more than 15,000 people in the 77th Independent Division of China, and there were only more than 20,000 troops in some miscellaneous units. The defeat in the battle some time ago was just that he underestimated the enemy, and now as long as Han Jiadian drags this branch of the army, and then sends a large army to go around the back of the branch army, this branch of the army will definitely collapse in a short time under the front and rear attacks.

This kind of tactics of bypassing the rear army and flank of the attacking enemy army is the most commonly used tactic of the Japanese army, and the general squadron will not care about the safety of the flank, let alone build the flank and rear flank positions. After the 77 Incident, Seishiro Itagaki's Fifth Division marched south from Chahar, and the cities of Zhangjiakou and Datong were captured one after another. In order to reverse the military decline, Yan Xishan, commander of the Second Theater of Operations, ordered more than 30 divisions of the Jin Sui Army and the Central Army to join the Japanese army in a battle at Xinkou.

Due to unfamiliarity with the Japanese army's combat methods and the lack of unity of command, more than 30 ** divisions actually fought to a draw with one of Itagaki Seishiro's divisions, and no one could help anyone. In desperation, Itagaki Seishiro then ordered a partial division to send troops to Niangzi Pass to attack the flank of the Jin Sui army, and the front-line troops who were afraid of being wrapped in dumplings were suddenly confused, Yan Xishan did not give the order to the front-line war and was quickly defeated, and finally more than 100,000 or 200,000 people ran out of hundreds of kilometers in a few days, and tens of thousands of people were killed and wounded and captured, and the second theater of the Xinkou Battle was defeated. So Lieutenant General Toji Yasui is ready to teach the independent 77th Division a lesson as well, and let the squadron see what the real tactics are.
