At about half past six in the morning on July 4, Han Yunhua led more than 60,000 main forces of his department to the area of Zhen'anbao, Chicheng County, Hebei Province, and hid in a hill outside Zhen'anbao.

In order to achieve the strategic and tactical goal of taking him by surprise, Han Yunhua ordered his troops to take a break during the day and march quickly at night. Along the way, there were dozens of devil strongholds, those who could detour as much as possible, and those who could not detour were sent to the saber special operations team to quietly touch them, and they also disguised the attack scene as if they had been attacked by the local Eighth Route Army guerrillas, so until Han Yunhua and others arrived at the periphery of Zhen'an Fort, the Japanese army did not know that the thorn in their eyes was no longer in Chahar.

With 60,000 troops in hand, Han Yunhua is confident that he can give the Japanese army a big surprise, Han Yunhua believes that as long as he operates well, these 60,000 troops can definitely make trouble in North China, and at the same time, they can also give the unsuspecting devils a heart-wrenching blow.

The troops accompanying Han Yunhua on this expedition were: the Second Assault Brigade, the 77th Independent Brigade, the First Cavalry Brigade, the Second Cavalry Brigade, the First Supplementary Corps, the Second Supplementary Corps, the First Artillery Regiment and the Second Artillery Regiment directly under the Military Region, the Fire Support Regiment, the Engineer Regiment, the Field Heavy Artillery Regiment, and the Sabre Special Operations Brigade. The unit in Han Yunhua's hands has almost covered 60% of the combat effectiveness of the Inner Mongolia Military Region, so whether Han Yunhua fights well or not almost determines the fate of the Inner Mongolia Military Region and the entire Chahar region.

At about one o'clock in the morning on July 4, Han Yunhua received a telegram from Yang Ruihua, who was staying in the base area, and Yang Ruihua told Han Yunhua that on July 3, the main force of the Japanese Sixth Division stationed in Guisui (Hohhot City) had advanced 70 kilometers to the east and had reached the territory of Zhuozishan County, which was less than 20 kilometers away from the county seat of Zhuozishan, and that the enemy's vanguard had engaged in sporadic exchanges of fire with the Zhuozishan Security Regiment, with casualties on both sides.

In the telegram, Yang Ruihua mentioned that the strength of the Japanese Sixth Division was very strong this time, in addition to the complete brigades, it also newly joined the four cavalry divisions and two infantry divisions of the puppet Mongolian army Li Shouxin's department, and at the same time, the sixth division also brought a tank brigade and two field heavy artillery wings, and the entire attack group reached a terrifying more than 50,000 people.

At the same time, the main force of the 39th Brigade of the Japanese Army stationed in Datong Special City also crossed the Jincha border and began to invade the Chahar area. The 39th Brigade was originally subordinate to the 20th Division of the North China Front, but the brigade suffered heavy losses in the last major war, and the troops of the Corps stationed in Mongolia were already stretched thin after many major battles, so the 39th Brigade has never been rebuilt. This time, the two infantry wings of the 39th Brigade were not only fully replenished, but also received the establishment of a cavalry wing, and at the same time, the Japanese troops stationed in Yanggao and Laiyuan were also under the command of the 39th Brigade, so the attack of the Datong Front was also extremely fierce. At present, the vanguard of the Japanese Datong Front has entered Fengzhen County, and has also engaged in skirmishes with the peripheral troops of the provisional independent 1st Brigade, and the result of the battle is that the Eighth Route Army suffers a slight loss.

Han Yunhua saw from Yang Ruihua's telegram that Yang Ruihua was under pressure now, and Han Yunhua also knew that it was indeed a little difficult for him to let Yang Ruihua, a person who had always been engaged in political work, command the remaining nearly 30,000 troops in the base area.

Han Yunhua still knows Yang Ruihua very well, and Yang Ruihua's status in the Inner Mongolia Military Region is already very prominent. In the Inner Mongolia Military Region, in addition to Han Yunhua, the absolute backbone, only the political commissar Shen Yuquan, the commander of the Saibei Military Division, Li Dayong, and Ye Baoguo, the prestige of these three people is a little higher than Yang Ruihua, and in addition, the status of others in the hearts of the soldiers is far inferior to Yang Ruihua.

Although Yang Ruihua was born in political work, he was also very talented in military command, and when he was the county magistrate in Yan'an, Yang Ruihua commanded a battalion of troops to annihilate a group of horse bandits of more than 1,000 people.

However, the rapid improvement of Yang Ruihua's status was also after he arrived in the Inner Mongolia Military Region, and at that time in Yan'an, although his ability was very strong, he could only succumb to a small position as a county magistrate. It's not that the political atmosphere in Yan'an is good, but that Yang Ruihua's background is not very popular with some people in the party.

Yang Ruihua was born in a traditional capital family in Beiping, and the Yang family was very powerful in Beiping and the entire North China region, but after the Japanese army launched a full-scale invasion of China, the Yang family quickly became a super fat in the eyes of the Japanese army. ,

After the Japanese army occupied Beiping, they hoped that Old Man Yang, that is, Yang Ruihua's father, would take up the position of the maintenance chairman of the Beiping area, but when Old Man Yang righteously refused. Old Man Yang is a hard bone, although the devil is coercive and tempting in every way, Old Man Yang just refuses to bow his head.

When the devil saw that the soft was not good, he began to use force, wanting to force the old man Yang out of the mountain, they sent someone to arrest Yang Ruihua's eldest brother and second brother into the gendarmerie in Beiping, and at the same time sent someone to seal up all the factories of the Yang family, but the old man Yang was still indifferent, that is, he did not agree to the devil's request.

However, the family is unfortunate, the old man Yang is not afraid of the death and oppression of the devil, but the direct descendants of the Yang family have not inherited the excellent genes of his old man, Yang Ruihua's eldest brother and second brother were arrested by the devil into the gendarmerie, and were intimidated by the devil, and the devil took these two soft bones to a prison set up by the devil in Beiping, and after watching the whole process of the Japanese army's interrogation of the "prisoner", Yang Ruihua's eldest brother and second brother quickly rebelled, and soon entered the Beiping Provisional Government controlled by the Wang puppet regime to hold important positions. When the old man Yang heard the news, he immediately vomited blood and died, and Yang Ruihua, who managed all the businesses of the Yang family in Shanxi, quickly broke off the relationship with his two elder brothers and hid in Taiyuan with part of the family property.

But Yang Ruihua's two elder brothers did not care about their brother's affection at all, and instructed Japanese agents to assassinate Yang Ruihua in Taiyuan. At that time, Yang Ruihua also quietly returned to his house in Taiyuan City several times, but his wife and daughter were no longer there, and there was still no news, and then in order to thank the underground party comrades for saving their lives, Yang Ruihua joined China ** and was sent to Yan'an to work.

But Yang Ruihua's background has made him not reused in Yan'an, with his education and ability, he can show his skills in economy and academics, but it is difficult to believe that a "big capitalist" young master-like figure has experienced too many apostasy, not to mention that his two elder brothers are still holding important positions in the puppet government in Beiping, to put it bluntly, they are being traitors, so Yang Ruihua has not been reused in Yan'an.

However, Yang Ruihua is indeed a rare highly educated talent in **, although many people in the party do not look down on him, but still let him serve as a county magistrate, but refused to let him take charge of the military. Yang Ruihua himself also knows his own situation, so although he has great ambitions in his heart, the reality is that he is indeed inferior to those old people who have fought all the way from Ruijin, Jiangxi, such as Han Yunhua, a young man who is only in his twenties.

However, this situation has changed rapidly since he came to the Inner Mongolia Military Region, where he was quickly promoted by Commander Han Yunhua, from a small county magistrate to a senior cadre at the military region level, in charge of all the large and small government affairs in the base area and the logistics work of more than 100,000 troops in the Inner Mongolia Military Region.

Now he is even more directly commanded by the nearly 30,000 troops in the base area, Yang Ruihua said that there is no pressure, and even he does not believe it.
