With the liberation of Yihezhuang, the north of the two counties of Lijin and the area of the Yellow River estuary in the northeast were all liberated, which also opened up the connection with the Jilu border area. At the same time, the Lubei District Party Committee of the Communist Party of China quickly dispatched working groups to these newly liberated areas, and successively established the Working Committee of the Reclamation District, the Anti-Japanese Democratic Government of the Reclamation District, and the five district committees and governments of Yong'an, Minfeng, Tinghe, and Luozhen.

From then on, the Eighth Route Army's troops further expanded their vertical and horizontal and circuitous areas, and immediately after that, they successively established consolidated and reliable rear areas and anti-Japanese base areas in various reclamation areas, thus achieving a fundamental change in strategy, and playing a decisive role in persisting in guerrilla warfare on the plains and striving for final victory in the northern Shandong region, especially in the Yellow River estuary area.

With the continuous expansion of the base areas, the vigorous development of the anti-Japanese situation, and the rising anti-Japanese sentiment in various places, the Japanese devils are increasingly feeling the crisis from all directions.

Soon after, the Japanese army generally implemented the "cage policy and the three-light policy" in all base areas in northern China, and Hebei, Shandong, and Shanxi were lined with artillery towers, crisscrossed by trenches, and densely covered with barbed wire. The successive sweeps have made the people of Hebei, Shandong, and Henan miserable and suffered heavy losses, and the situation in the already resource-poor base area has become even more difficult.

In order to carry out the frenzied "iron wall encirclement" sweeping strategy, the Japanese army gathered more than 5,000 Japanese puppet troops in Jinan, Weixian, Huimin and other places, divided their troops into five routes, and surrounded the area of Huangcaopopo, where the head of the Lubei Military Region of the Eighth Route Army was located, in a vain attempt to wipe out the newly established liberated areas and people's power of our party in one fell swoop, and encircle and annihilate the main force of our army.

At dawn that day, the sound of gunfire suddenly came from all directions, and immediately following the sound of gunfire, the correspondent hurriedly ran over and reported to Commander Yang Guofu: Many enemies have suddenly surrounded the barren grass slope, and the 2nd and 4th regiments of the Eighth Route Army in front have formed a fan-shaped attack from the east and west sides, and the organs and masses of the military region are requested to move quickly.

When Commander Yang Guofu heard this, he was secretly surprised: Fortunately, after the Battle of Yihezhuang, the main force of the Eighth Route Army quietly moved to Beidawa to rest, otherwise it would have been really cold to let the devil make dumplings. Without further ado, Commander Yang immediately ordered the regiments directly under the Military Region to quickly cover the transfer of the masses, with the machine gun company opening the road and the guard company guarding the way, and he himself led the organs of the Military Region to take advantage of the anti-Japanese trenches and grassy slopes that had been dug earlier to choose an opportunity to break through the encirclement covertly.

On the east and north sides are the sea and the mouth of the Yellow River, with a vast depth space, which is the rear of the Eighth Route Army; To the south and west are large fields and important areas of the county occupied by the enemy, which are the enemy's territory. Commander Yang judged that the current enemy must have deployed heavy troops on the east and north sides, with the purpose of first blocking the rear route of the Eighth Route Army and gradually implementing the advance plan to the south and west. On the one hand, he ordered the organs of the military region to quietly move to the south, and on the other hand, he led the machine gun company to rush to the north in coordination with the second and fourth regiments, assuming a posture of breaking through to the north. Sure enough, a large number of enemies were slowly drawn over, and the battle gradually stalemate.

On the position, as the newly captured Type 92 heavy machine gun of the Eighth Route Army suddenly sounded, the devils soon discovered that this machine gun was the one they had taken from the Eighth Route Army in the last battle. So the enemies from all walks of life were eager to take revenge and began to rush wildly, desperately trying to recapture the heavy machine guns. Seeing that the enemy was successfully attracted, Commander Yang decisively gave the order: the machine gun company organized several light machine guns to cover alternately, and the heavy machine guns fought and retreated, moving left and right, leading the enemy's nose from north to west; He led the guard regiment to cover the rapid retreat of the military district organs from the south. In the end, it was agreed that the two roads would converge in the northeast barren valley.

Then, the sound of gunfire was intermittent, left and right, far and near, and the time was slowly approaching noon.

To the south of the battlefield, not long after the team led by Commander Yang Guofu turned around, the group was quietly retreating along a weedy trench. Unexpectedly, when I looked up, I collided with a group of enemies who were searching from the east.

The devil commander not far away suddenly discovered Commander Yang's jujube red war horse, and immediately commanded the outflanking, shouting loudly: .

"There are officials on the Eighth Road, don't shoot guns, catch them alive! ……”

As soon as he heard this, the air in the trench immediately became tense.
