The 20th Division of the Japanese Army appeared very suddenly, which could not help but make Han Yunhua think of something else. The Inner Mongolia Military Region is also a large military region with a population of 1.5 or 600 million and an army of more than 100,000. This time, the 20th Division of the Japanese Army quietly went north, did it come to the Inner Mongolia Military Region? And how many 20th divisions are there in the whole of North China.

Han Yunhua did not believe that the Japanese army was coming at the Nationalist Government, although there were still a few troops controlled by the Nationalist Government in the southern Hebei region, but there was no need for the Japanese to use an infantry division to deal with it, both in terms of quantity and quality. The strength of the Eighth Route Army in the entire Hebei region is much stronger, not to mention the old force Jin-Cha-Ji Military Region, even the later established Inner Mongolia Military Region has a very strong influence in Hebei, and just last year, with the strong support of the party Central Committee and the Eighth Route Army Headquarters, the Central Hebei Military Region was established in the central Hebei region.

Such a huge strength is definitely not what the Japanese army wants to see, and the foundation of the Japanese army's ruling power in North China is also in the Hebei region, which is also one of the reasons why the Communist Party can openly shout out that the battlefield behind the enemy line is also the main battlefield of the anti-Japanese battlefield in the later stage of the Anti-Japanese War.

Even during the first Battle of Wuhan, when the Japanese army was already overstretched, the Japanese army did not stop sweeping public order in Hebei, which shows that the Japanese attach great importance to Hebei.

This time, is the beginning of a sweep in the northern transfer of the 20th Infantry Division? But this does not make sense logically, and others may not be clear, but Han Yunhua can see very clearly that the Japanese army now has a lot of troops in the south, and it is an exaggeration to say that it is a million troops, but there are still 500,000. However, in this North China region, there are only five divisions and two independent brigades, and the total strength is less than 200,000.

Although the Japanese army hyped up their brilliant achievements south of the Yangtze River in the newspapers, Han Yunhua also saw clearly that the Japanese army was strong in the middle. Most of the troops were quietly transferred to the south to fight the Battle of Wuhan, while the troops left in Hebei, Shandong, Shanxi, Henan, Chahar, Suiyuan, Rehe, Anhui, and other provinces and cities in North China were less than six divisions, of which Shandong Province accounted for nearly two divisions, and the First Army of Shanxi Province also accounted for more than two divisions, that is to say, there was only one division in the entire Hebei Province. Han Yunhua really admired such a troop arrangement, but the secrecy work of the Japanese army still made Han Yunhua feel very emotional, before the second battle of Wuhan, the Japanese army in North China transferred three divisions, but on the Chinese side, neither the Communist Party nor the Kuomintang knew any news. When the numbers of the three infantry divisions appeared on the battlefield of the Battle of Wuhan, the Chinese side came to an understanding.

Han Yunhua of Henan and Anhui provinces is not going to do anything, because on the one hand, these two provinces are not the main sphere of influence of the CCP, and the strength of the CCP in these two provinces is extremely limited, and it is not even comparable to a few small warlords in this province. In addition, the geographical location of these two provinces is close to the Yangtze River, so they are in the auxiliary battlefield of the Second Battle of Wuhan, so Han Yunhua and the entire Eighth Route Army have no way to hold the two provinces.

Although he was extremely unwilling, Han Yunhua could only give up dealing with the Japanese army in Henan and Anhui provinces. But Han Yunhua will not be polite to the Japanese troops in Hebei, Shanxi, and Shandong. Maybe Han Yunhua's actions were too much, and the headquarters of the Japanese North China Front felt the pressure, if this 20th Division was transferred north to protect itself, then Han Yunhua would not be worried. But if the Japanese army wants to make any moths, then Han Yunhua must be prepared. …,

Han Yunhua still couldn't find a clue after analyzing and analyzing, but this matter could not be ignored, so Han Yunhua had no choice but to order the two brigades of the Second Brigade and the Third Brigade to intensify the attack on Handan while ensuring the complete annihilation of the Japanese army in Feixiang County. As for the Japanese reinforcements from Shimen, Jiang Yunshan ignored them for the time being, it was useless to intercept them, and the comprehensive force of nearly 6,000 people in an infantry wing, a cavalry wing, and an artillery wing was definitely not comparable to the Yamazaki brigade.

If the 2nd and 3rd Brigades wanted to swallow so many Japanese troops in one gulp, the result would definitely not be much better.

At the same time, Han Yunhua also had to take precautions and report the information of the mysterious movement of the Japanese army to the Eighth Route Army. After all, the 20th Division of the Japanese Army was originally subordinate to the battle sequence of the First Army of the Japanese Army stationed in Shanxi, and the sudden northward movement of the 20th Division also had a great impact on the Eighth Route Army in Shanxi.

The headquarters of the Eighth Route Army also attached great importance to the information reported by Han Yunhua, at this time Mr. Zhu had already returned to Yan'an, and only Mr. Peng was still commanding the operation on the front line in Shanxi, after receiving Han Yunhua's telegram, Mr. Peng immediately convened a meeting of several senior cadres of the headquarters, and Nie Rongzhen, commander of the Shanxi-Chahar-Hebei Military Region, and Liu Bocheng, commander of the 129th Division, who were working at the headquarters, were also asked by Mr. Peng to participate in the discussion.

After more than two hours of analysis and discussion, the leaders of the General Headquarters unanimously agreed that the 20th Infantry Division suddenly went north not for the Shanxi-Chahar-Hebei Military Region, and certainly not for Han Yunhua's headquarters, because it should have been aimed at the newly established Jizhong Military Region, and the reason was probably because Han Yunhua's headquarters had done too much in southern Hebei, and the Japanese North China Front Army could not bear it, but Han Yunhua's instructor, who had just been formed, did not have a good reputation, and the Japanese army seemed to have included them in the Jizhong Military Region, thinking that they were "making trouble" in southern Hebei Because it should be a unit of the Jizhong Military Region, it was decided to send troops to attack the nest of the Jizhong Military Region and completely solve the hidden dangers in Hebei Province before the Inner Mongolia Military Region launched a full-scale attack.

As soon as the analysis of the headquarters came to a conclusion, the entire conference room suddenly fell silent, and the big guys had crawled out of the sea of corpses and blood, and they were very sensitive to war. In particular, Division Commander Liu, one of the gods of war of the Republic, saw the fighter plane, and after about two years of development, the development speed of the 129th Division was not much slower than that of Han Yunhua's division. On September 30, 1937, the headquarters of the 129th Division led the 386th Brigade, the 769th Regiment, the Teaching Regiment, the Cavalry Battalion and other units, totaling more than 9,100 people, from Fuping County, Shaanxi, to cross the Yellow River to the east and go to the anti-Japanese front in North China, leaving the 385th Brigade Headquarters and the 770th Regiment and the battalions of engineers, baggage, artillery, and spies in the Shaanxi-Gansu-Ningbo Border Region. In October, according to the decision of the Central Committee of the Communist Party of China, the political commissar system was restored to units above the regiment level, and Zhang Hao was reappointed as the political commissar of the division (succeeded by Deng Xiaoping in January 1938). Wang Weizhou served as the political commissar of the 385th Brigade, and Wang Xinting served as the political commissar of the 386th Brigade. On October 19, the 769th Regiment, the advance unit of the 129th Division, attacked the Japanese frontline airfield in Yangmingbao, Dai County, Shanxi Province, at night, destroying 24 aircraft. Then, the main force of the division advanced to the Pingding and Xiyang areas south of the Zhengtai (now Shitai) Railway, attacked the Japanese troops advancing westward along the Zhengtai Railway, and successively won victories in the battles of Changshengkou, Qigancun, Huangyadi, and Guangyang. In mid-November, in accordance with the instructions of the Central Military Commission of the Communist Party of China and the headquarters of the Eighth Route Army on the establishment of an anti-Japanese base area based on the Taihang and Taiyue mountain ranges, the 129th Division deployed in the area east of the Tongpu Railway, south of the Zhengtai Railway, and west of the Shijiazhuang-Cixian section of the Pinghan Railway.

In order to restrain the Japanese army's attack on the Yellow River defense line and cooperate with the Kuomintang Army in southern Shanxi and the Eighth Route Army in the northwest and southwest of Shanxi, the 129th Division launched traffic sabotage battles and ambush warfare along the Zhengtai Railway and the Handan (Dan) Chang (Zhi) Highway in February and March 1938, and successively won victories in battles such as Shentouling and Xiangtangpu, and annihilated more than 2,000 Japanese troops. From the beginning of April to the 27th, under the command of the headquarters of the Eighth Route Army, the 129th Division fought together with the 344th Brigade of the 115th Division, the 1st and 2nd Columns of the Decisive Death Squad, and smashed the "Nine-Route Siege" of more than 30,000 Japanese troops in the southeast of Shanxi, recovered 18 county towns including Liaoxian (now Zuoquan) and Licheng, and consolidated and expanded the Shanxi-Hebei-Henan anti-Japanese democratic base areas. In late April, in order to carry out guerrilla warfare on the plains, Xu Xiangqian led the 769th Regiment and the 689th Regiment of the 115th Division to advance into southern Hebei and expand the base area in southern Hebei; The 386th Brigade developed into northern Henan and opened up anti-Japanese base areas in the mountainous areas of Anyang, Linxian and Huixian in northern Henan. In order to strengthen the building of local armed forces and unify the command of various guerrilla detachments, the Shanxi-Hebei-Henan Military Region was established. After more than a year of struggle, the troops of the 129th Division have been greatly developed, and an independent brigade (Chen Zaidao as the brigade commander and Song as the political commissar) and supplementary regiments and cavalry regiments have also been formed; and combined the 769th Regiment, the Independent Regiment, and Wang Naigui's detachment into the new 385 Brigade (Chen Xilian served as the brigade commander and Xie Fuzhi served as the political commissar); In addition, the basic guerrilla detachments were organized into advance detachments, independent detachments, and independent guerrilla detachments. By October 1938, the 129th Division had grown to more than 50,000 men. In late December, the 129th Division led the main force of the 386th Brigade and an advance detachment to advance into southern Hebei and northwest Shandong, and in January ~ March 1939, together with the troops of the Southern Hebei Military Region, smashed the "sweep" of more than 30,000 Japanese puppet troops, and won the victory in the battle of Xiangchenggu. After March, when the focus of the Japanese army's "sweep" shifted to the mountainous areas, the main force of the 129th Division returned to the Taihang anti-Japanese base area and smashed the Japanese army's summer "sweep" of the Taihang Mountains.

With full trust in the combat effectiveness of the 129th Division, Division Commander Liu believed that it was possible and necessary to carry out a large-scale military strike against the Japanese army, and the main goal was to carry out continuous sabotage battles on the Baijin, Deshi, Zhengtai, Pinghan and other railways and major highways, and if the war went well, it could smash the Japanese army's "cage policy" ...... in one fell swoop.
