On 5 March, with the arrival of Master Chen, the atmosphere on the front line suddenly became tense, and the Japanese reconnaissance planes that arrived close to reconnoiter from time to time pushed this tension to the first place.

At 8:10 p.m. on the 5th, Master Chen ordered the troops on the front line to prepare and launch an attack on the Japanese army at Sichakou twenty minutes later. Of course, Master Chen also knew that such a large-scale operation could not be concealed from Lieutenant General Yasui Toji, because Han Yunhua had played a surprise attack in the eastern Hebei region, more than 60,000 troops appeared in the eastern Hebei region silently, and the Japanese puppet army was defeated, and finally even the provincial capital city of Rehe was lost, and after this war, the economy of the eastern Hebei region regressed for more than ten years, and the rubble of Chengde City has not been cleaned up until now. Therefore, the Japanese puppet army in eastern Hebei is very sensitive to the infiltration of the Eighth Route Army, and the investigation is unprecedented, so Master Chen is ready to blatantly attack this time.

Of course, Yasui Toji is not a vegetarian, when he learned that the number of Chinese troops entering Guyuan County exceeded 20,000, Lieutenant General Yasui Toji was also surprised, although 20,000 troops did not have much pressure on the always confident Lieutenant General Yasui Toji, after all, the Japanese puppet army in eastern Hebei combined exceeded 70,000. Although he looked down on the security forces (puppet army) in North China like all Japanese officers, Lieutenant General Yasui Toji still did not think that with this mere 20,000 men, the Chinese army could take advantage of his second and fourth divisions.

To be on the safe side, Lieutenant General Toji Yasui dispatched an infantry wing and an artillery wing on the 4th to urgently reinforce the Japanese puppet army at the four forks. After the First Battle of Saibei, Han Yunhua's forces expanded to Guyuan County. However, due to the strength of the Second Division, coupled with the Sixth Division, the 21st Division, the 26th Division, the 3rd Independent Mixed Brigade, the 4th Independent Mixed Brigade, and the 1st Infantry Wing in North China, the elite Japanese troops gradually approached Han Yunhua's headquarters, so Han Yunhua wisely chose to retreat, resulting in only half of Han Yunhua's headquarters in the entire Guyuan County, and the remaining half was still in the hands of the Japanese army. Because Han Yunhua's troops occupied the county seat, the Japanese army built a strong defense line at the four forks 30 kilometers away from Guyuan County, and also sent heavy troops to guard it.

Knowing that the number of the Shina troops in Guyuan County exceeded 20,000, coupled with the estimation of the combat effectiveness of Han Yunhua's troops, Lieutenant General Yasui Toji believed that the strength of the two infantry brigades at Sichakou would definitely not last long, so he ordered the commander of the 30th Infantry Wing, Suzuki Shigeichisa, to lead his troops and the 2nd Cavalry Wing to reinforce Sichakou.

Sichakou is a traffic artery, to the east you can enter Longhua Chengde, to the north you can enter Duolun, to the south you can go straight to Fengning, to the west you can reach Guyuan Kangbao. The geographical location is very important, coupled with the terrain is easy to defend and difficult to attack, so the Japanese army built a solid defense line here to prevent the Inner Mongolia Military Region from entering eastern Hebei.

After the general offensive began, the 1st Battalion of the 88th Regiment served as the main attack of the battle, and the 1st Battalion of the Fire Support Regiment and the 1st Battalion of the Artillery Regiment were responsible for fire cover. After five minutes of shelling, the soldiers of the first battalion skillfully approached the Japanese position, at this time the Japanese position was filled with gunsmoke, and it was impossible to see the devils in the enemy's trenches clearly, but the very experienced battalion knew that this artillery bombardment was not a big threat to the devils with strong fortifications, so the first round of attack was very cautious.

Sure enough, when the soldiers of the first battalion approached a distance of less than eighty meters from the Japanese position, the Japanese position suddenly became lively, and all the light and heavy firepower opened fire on the first battalion at the same time, and the Japanese artillery also began to counterattack. Ten minutes of retaliatory artillery bombardment caused a lot of casualties, but fortunately there was an artillery regiment to suppress it, otherwise the Japanese artillery alone would have been enough for the soldiers to drink a pot. What made Yiying feel even more tricky was that the devils of the second division had a terrifying shooting accuracy, and in just ten minutes, more than 50 people in the first battalion were shot in the head, and it seemed that the devils on the opposite side were all marksmen. And what they are holding in their hands is not an ordinary 38 big cover, just like the special combat team of the Inner Mongolia Military Region, every bullet has to bite flesh and drink blood, and the name of elite is indeed well deserved. Seeing the strength of the Japanese army, Master Chen was really afraid that these troops in his hands would not be able to bear this heavy responsibility.

Master Chen saw through the telescope from the light of the fires that exploded from time to time on the battlefield that the first attack of the 1st Battalion of the 88th Regiment was repulsed in less than half an hour, and in addition to the wounded who were brought down, at least 60 corpses were left on the battlefield. Master Chen was shocked and felt relieved at the same time, you must know that under this kind of intensity of attack, it is already a miracle that only less than 100 people are lost in a round of attack, if his original 386 Brigade is used in this battle, at least five or six hundred people will be lost in this charge alone. But on the other hand, if it weren't for this elite, he wouldn't dare to take the initiative to provoke the well-known elite of the Japanese army. Master Chen was also deeply shocked by the combat effectiveness of the 88th Regiment, which was worthy of being the elite created by Han Yunhua and Li Dayong, and its combat experience and the quality of its soldiers were extraordinary. The Japanese army was so dense with fire, but not a single soldier panicked, and when he was wounded, he only lurked in the position and did not move, and after retreating, people knew that they were injured, because on that occasion who moved and who died. The inexperienced ones are likely to lose their lives in a single face, and they can still count on the troops to withdraw from the battle in such an orderly manner as a battalion. ,

What surprised Master Chen even more was that in less than 20 minutes, the first battalion once again organized an attack, and the remaining more than 500 soldiers were divided into two echelons to attack, the first was almost all light and heavy machine guns, submachine guns and other automatic firepower, and the second echelon was all soldiers armed with rifles. The fire support regiment was seconded to the battlefield by a battalion with weapons and men, and it seems that the commander of the first battalion is ready to win with firepower.

Wang Yuanhua said in Master Chen's ear: "Wang Yunkai, commander of the first battalion of the 88th Regiment, is a commander who was personally taught by the commander, and his command ability is very outstanding and courageous. In the first Battle of Saibei, he led a platoon to hold the empty city, inducing the main force of the Japanese army to pounce on Fengning, creating an opportunity for the main force to sneak attack Chengde, and was later promoted to company commander by the commander, and was promoted to battalion commander after the expansion of the unit. He is one of the officers that the commander focuses on cultivating, and at the same time, this guy is also a bold master, except for the commander, no one else wants to transfer him without a good reason. This time this guy is ready to work hard, even the first battalion of the fire support regiment was brought to the front line by this guy, hey, I don't know what crooked ideas this guy used............"

Before Wang Yuanhua's words were finished, Wang Yunkai's side began to attack, the difference from the previous time was that this time the attack of the first battalion was obviously much more violent, the first batch of attacking troops was as many as 700 people, and the heavy machine guns were as many as 55, and the first battalion of the fire support regiment was all sent to the battlefield by Wang Yunkai. The artillery regiment was covered by fire, and the Japanese positions at the four forks were once again shrouded in firelight, and violent explosions came one after another, and from time to time there were ghost soldiers who were blown out one after another.

Taking advantage of this opportunity, the soldiers of the first echelon quickly moved to the front of the Japanese army and other positions. This time, the artillery regiment shelled for a much longer time, and the shells fell less than 30 meters away from the first battalion, and the shrapnel of the shells was likely to hit their own people.

"Ask the artillery regiment what's going on, don't you know that our troops are also on the position?" Master Chen asked with some confusion. The artillery commander knew that he was an old Red Army who had followed the chairman from Jiangxi all the time, and he was calm and experienced in combat, so he was not the kind of person who didn't care about the life and death of his own people, so why did he fire artillery without any scruples?

Soon the guards came back and reported: "Report to the division commander, Regiment Commander Li reports that it was Battalion Commander Wang who called him to ask him to do so, and Battalion Commander Wang is ready to advance to a distance of 50 meters from the Japanese position under the cover of artillery fire......

Master Chen was shocked again, no wonder this army could win the battle, these soldiers are real Predators, not only cruel to the enemy, but also cruel to their own people, they will never back down when it is time to sacrifice, what a group of lovely people.

At this time, not only Master Chen was shocked, but even the supreme commander of the Japanese army, Suzuki Shigeichi Sasa, who was directing the battle not far away, was also shocked. The Japanese artillery wing was hurriedly ordered to open fire on the temporary positions of the 1st battalion, but because the distance between the two sides was less than 50 meters, shells fell on the Japanese positions from time to time.

At this time, the artillery of the Chinese side stopped attacking, and at the same time a battalion launched an attack, and intensive fire was pounding on the Japanese positions. The Japanese infantry, who had just recovered from the shelling of the squadron, had not yet organized an effective counterattack when they were assaulted into the trench by a battalion of fighters armed with machine guns.

Subsequently, the follow-up units of the 1st Battalion quickly attacked to support the first echelon in attacking the first line of defense of the Japanese army. After half an hour of hand-to-hand combat, the defenders of a large Japanese battalion wisely retreated.

Less than two hours after the start of the battle, the first line of defense of the Japanese army collapsed on all fronts, and under the command of commander Shigeichi Suzuki, the second line of defense was also the last line of defense of the Japanese army, and compared with the first line of defense, the second line of defense was weaker in terms of geographical location and firepower configuration.

In the first encounter, the 1st Battalion of the 88th Regiment of the 77th Independent Division lost 286 men, killed 98 people, seriously wounded 108 people, and lightly wounded 70 people. The 1st Battalion of the Fire Support Regiment lost 133 people, 64 killed and 67 wounded. The corpses left on the position by the Japanese army were 288 people, and the wounded could not be counted. In the first encounter, the independent 77th Division had an absolute advantage, and the Japanese 2nd Division not only lost the first line of defense at the four forks, but also suffered heavy losses in troops.
