On 15 July, all units of the North China Front Army gathered in Zhangbei County, first of all, the 21st Division, which was the landlord, "defeated" the main force of Yang Chengwu's army, which was originally stationed in Zhangbei County, and occupied the county seat of Zhangbei. Subsequently, the main force of Gu Shoufu's department was frustrated under Jining City, and the main force of the 26th Division also came to Zhangbei County.

At present, the small city of Zhangbei County has gathered three integrated divisions and regiments of the North China Front Army, plus two reading brigades and one infantry brigade, with a total strength of 70,000 people, not counting the nearly 30,000 puppet army units that have cooperated with various units in the battle.

The goal of this eastward expansion has long been determined, that is, to completely eliminate the main force of Han Yunhua's army, solve the worries of the Great Empire, and completely build the northeast and north China of China and the Mongolian Xinjiang region into the rear base of the empire, so as to lay the foundation for the empire to realize the imperial hegemony of the common prosperity of Greater East Asia.

However, after this period of arduous fighting, all units of the North China Front Army have a relatively clear understanding of the combat effectiveness of Han Yunhua's troops, and they must not treat this branch army as an ordinary branch army, otherwise they will suffer a big loss.

Throughout the more than 20 days of fighting, although the Great Empire dispatched more than 100,000 troops, plus the puppet army and various divisions, brigades and regiments used to contain other units of the Eighth Route Army, the total strength of the army reached almost 1780,000 people, but the results achieved were very limited, although the old nest of Han Yunhua's troops was almost destroyed, but the troops suffered heavy casualties, and the materials and ammunition consumed alone could not be made up for in a short time. However, almost all the strongholds with military value are still in the hands of the Chinese army, including Daqingshan and Haojia Dazhai, the final strongholds of Han Yunhua's department, and of course, Jining, the largest city in Chahar, it can be said that this military operation of the North China Front only drove Han Yunhua from Chahar to eastern Hebei, and in fact, the main force of Han Yunhua's department was not fatally hit.

The war has been going on until now, no one dares to and cannot underestimate this previously unknown Chinese army, fortunately, Zhangbei County has been taken, and now what Gu Shoufu and others have to do is to quickly advance eastward, complete the encirclement of the main force of Han Yunhua's army, and recapture Chengde.

On July 15, at about eight o'clock in the afternoon, the army in Zhangbei County began to march to Chengde. According to the combat order issued by the North China Front Headquarters, Gu Shoufu led his Sixth Division and the three puppet infantry divisions of Li Shouxin's department from Zhangbei County to the north to attack Guyuan. The commander of the 26th Division, Lieutenant General Hou Guan Chun, led the 26th Division, the 39th Infantry Brigade and a puppet army garrison regiment to attack Fengning in the east. Finally, the commander of the 21st Division led the main force of the 21st Division to return to Zhangjiakou with the 3rd Brigade to return to Zhangjiakou, and then pass through Beiping, and then directly attack Chengde from Beiping.

Soon after the army was launched, all departments of the Inner Mongolia Military Region received the news, and the first to receive the news was undoubtedly Yang Chengwu. The army was menacing, heavy troops pressed the border, and tens of thousands of elites poured into Zhangbei County, making Yang Chengwu wisely choose to retreat. Although he also had more than 20,000 troops in his hands at that time, including the absolute main assault brigade of the Inner Mongolia Military Region. But compared to the three-way army of the army, the little force in Yang Chengwu's hands is nothing, and Zhangbei County is not the same as Jining, there are no complete fortifications like Jining, if Yang Chengwu's troops are surrounded by devils in Zhangbei County like Yang Ruihua's department, the ending will definitely be completely different from the ending of Yang Ruihua's department.

At eight o'clock in the evening of the 15th, Yang Chengwu received the news that the main force of the devils had moved eastward, and immediately ordered the troops to assemble. Now that the main force of the devil has left, the remaining Yamashita brigade is just a brigade that has been disabled by Yang Chengwu, and the threat to Yang Chengwu's department is really limited. Therefore, Yang Chengwu felt that as long as he had trouble with the devil again, then the pressure on the commander's side would definitely be reduced. Even if the devil doesn't send troops back, he will leave a part of the troops to defend himself, and the troops used for the attack will definitely be reduced, and he can be regarded as indirectly helping the commander.

The speed of the army's attack was very fast, and by 10 o'clock in the morning of the 16th, Gu Shoufu's headquarters had reached the territory of Guyuan County, although there was still a considerable distance from Guyuan County, but the large and small strongholds, traffic arteries, and commanding heights of strategic value along the Guyuan Road were all taken by the Sixth Division. The speed of the 26th Division's march was not slow, and Lieutenant General Houguan Chun did not order the troops to rush desperately like Gu Shoufu, but divided the troops into three offensive echelons, and its vanguard troops had already reached the territory of Fengning, which was less than 30 kilometers away from the county town where the 1st Supplementary Corps Regiment was stationed.

Despite this, there was no tension at all in Han Yunhua's temporary headquarters, and the news gathered by various departments made a large group of staff officers and cadets in the headquarters unanimously believe that although the war was likely to be further expanded, in a few days, the entire North China region would blossom everywhere, and the devils and their puppet regimes would be greatly damaged even if they did not collapse, and it was by no means possible to restore the original level of prosperity in a short period of time.

Of course, this kind of emotion also infected Han Yunhua, although the war is imminent, such an emotion is taboo for soldiers, and there is a suspicion of being a rival. But Han Yunhua gave way, and the judgment of these young staff officers was still very correct. He had already ordered the Saibei Army Division and the Second Brigade of the Provisional Reading Force led by Shen Yuquan to prepare for a surprise attack on Guisui and Baotou, and as long as his order was given here, the other side would capture these two big cities as soon as possible.

At five o'clock in the afternoon of the 16th, Gu Shoufu's headquarters launched a full-scale attack on Guyuan County, and the 3rd Regiment of the 1st Supplementary Corps stationed in Guyuan reluctantly retreated after resisting to the death for three hours. At the same time, Fengning County was also attacked by devils. However, stationed in Fengning is a regiment of the First Supplementary Corps, the combat effectiveness of this regiment is very strong, after the capture of Chengde, Han Yunhua specially added a large number of weapons and equipment to this regiment, and the heavy machine guns alone were increased by 30 at once, and there were countless light machine guns and rifles. Even mortars, grenadiers, 75mm mountain artillery, and field artillery, which are in great short supply in the army, have been added a lot, and it can be said that the first regiment is now armed to the teeth, and it is not inferior to the 6th Division, the most elite division in North China, and it is not at all comparable to a second-rate garrison division like the 26th Division. Therefore, the first regiment took advantage of the favorable terrain outside Fengning County to block the 26th Division. In order to achieve the task of holding back the enemy, a regiment specially seconded a squad of special combat personnel from the headquarters to block the troops along the way, especially the officers who wanted to shoot a large number of devils.

The combat method of the first regiment was still very effective, and under the continuous harassment and resistance of the first regiment, the marching speed of the 26th Division was extremely slow, and the angry commander of the 26th Division, Lieutenant General Houguan Chun, smashed his beloved porcelain teacups of the Ming Dynasty in China.

However, the sharpness of the 26th Division has been lost, and even if Lieutenant General Chun of Korea scolds Baga in the back, it will be in vain. The speed of the march of the troops, who lay down at the sound of gunfire, can be imagined, and it was not until about ten o'clock in the evening of the 16th that the first and second substitutions of the 26th Division converged, and the speed of the troops was considered to be faster.

The battlefield in eastern Hebei is already full of rumors, and the devil's fighter planes will go to Chengde almost every two hours to inspect the vicinity, and once they see a target of slight military value, they will bomb it. The most unfortunate thing is a group of unscrupulous tomb robbers, who were seen by the devil's pilots when they were digging in the deep mountains, thinking that the Eighth Route Army was digging tunnels or building trenches.............
