The former deputy commander-in-chief of the Eighth Route Army, in accordance with the orders issued by the headquarters to counter-sweep the enemy, successively made corresponding supplementary opinions to all military regions and corps, and then the deputy commander-in-chief left Wang Jiayu, the former commander of the Eighth Route Army headquarters, and led several people through the enemy's blockade line to various battlefields in the southeast of Shanxi Province to understand the situation.

Every time he walked through a village, he saw that after being swept away by the Japanese army, the whole village was in ruins, some villages were still smoking gunpowder and flames, and the people who were killed by the enemy were lying in the villages, and he burst into tears of grief and was extremely angry.

The tragic scenes aroused the anger of the deputy commander-in-chief, and his heart was as heavy as ten thousand arrows piercing his heart, and he angrily rebuked: "The Japanese invaders are too inhumane, occupy our country's land, kill our villagers, plunder our resources, and implement a scorched earth policy. ”

At this time, the commander of the Katayama Brigade of the Fourth Independent Mixed Brigade of the Japanese Army ordered to send more than 10,000 enemy puppet troops on 20 October to launch a frantic sweep against the leaders of the Eighth Route Army on the northeast line of the Qingzhang River.

Commander Liu of the Shanxi-Hebei-Henan Military Region ordered the main division (129) to set up an ambush between the peaks and valleys of the Qingzhan River, carefully set up an ambush, and launched a counter-sweeping battle with the attacking enemy.

The 14th Regiment of the 385th Brigade was ordered to march rapidly to Qiaoba and Fenglingdu to set up an ambush to block the enemy puppet army that was rapidly advancing from Liao County to Matian, and to block the attacking enemy outside the position, so as to cover the safe transfer of the Northern Bureau of the Eighth Route Army, the heads of the party, government, and military organs of the border region, and the front command organs of the headquarters of the Eighth Route Army.

The enemy attacking in Liao County gathered more than 300 enemy puppet troops, took a truck to a thousand meters west of Qiaoba, and got out of the car to attack the 14th Regiment of the Eighth Route Army holding on to Qiaoba.

In accordance with the instructions of Commander Liu of the Military Region, the 14th Regiment held back the enemy and resolutely blocked the attacking enemy under the bridge and dam position.

The Japanese commander brandished his command knife, pointed at the position of the Eighth Route Army of Qiaoba and roared: "A regiment of the Eighth Route Army of Tuba is holding the bridge, as long as the imperial warriors of the Imperial Japanese Army launch an attack in the spirit of bushido, they will definitely kill all the Eighth Route Army of Qiaoba and Tuba, and kill them for the common prosperity of Greater East Asia——。 ”

In the eyes of the commander of the devils, as long as the Japanese army launches a strong attack, it will break through the position of the Eighth Route Army in the shortest possible time, go straight to Matian, surround the head of the border area of the Eighth Route Army, wait for reinforcements, and eliminate it in one fell swoop.

The devil commander who misjudged the situation on the battlefield did not launch three attacks in a row as he wished, but did not break through the bridge and dam position of the Eighth Route Army, but left dozens of devil corpses at the front of the position.

The devil commander didn't expect that the Eighth Route Army, which was guarding the bridge and dam position, would have such a strong combat effectiveness, and he still howled unwillingly: "Warriors of the Great Japanese Empire, we are all the best soldiers of His Majesty the Emperor——。 ”

The Japanese army launched another attack on the Qiaoba position, this should be the sixth counterattack, the 14th Regiment and the enemy fought fiercely at Qiaoba, the fight was very fierce, the strength of a regiment and a squadron of devils armed to the teeth were engaged, although they had an advantage in strength, but the weapons were far inferior to the enemy, and the position was almost broken through by the attacking enemy several times.

It was slowly getting dark, and the Japanese commander was never able to lead his troops to break through the 14th Regiment's bridge-dam position.

The devil commander desperately ordered light and heavy fire support to cover the troops for the last attack on the position of the Eighth Route Army at Qiaoba.

The commander of the 14th Regiment stood up from the position with a gun, and shouted in the face of the little devil at his feet: "All the cadres and soldiers of the 14th Regiment, fighting into the enemy group with guns, must keep their positions and cover the safe transfer of the head of the organ." ”

The soldiers of the 14th Regiment bravely jumped out of the trenches, armed with rifles loaded with bayonets, fought out of their positions and rushed into the enemy group, and engaged the enemy in a white-knuckle battle.

At the last moment of their lives, some soldiers threw down the guns in their hands, pulled the grenades on their bodies, and threw themselves at the place where the devils were crowded.

After more than half an hour of fighting with blood and fire, the Japanese commander finally killed the attacking little devils with superior forces, and the Japanese commander saw that the sky was dim and was afraid that the reinforcements of the Eighth Route Army would be surrounded, so he had to order a retreat and fled back to Liao County in a panic.

The captain of the Okazaki Brigade of the Fourth Independent Mixed Brigade of the Japanese Army led more than 600 little devils to frantically pounce on the waterwaist arsenal of the headquarters of the Eighth Route Army.

Captain Okazaki didn't know that in this deep mountain, there would be a hidden waterwaist arsenal of the Eighth Route Army, but because he was not familiar with the terrain and landform here, he blindly invaded here, trying to hunt down and kill the head of the command organ of the border area of the Eighth Route Army along the route of Xijing, Huangyagou Valley, and Zuohui.

Shuiwaist Arsenal, is the commander-in-chief and deputy commander-in-chief of the Eighth Route Army, chief of staff, in the 39th year, personally entered the Huangya Valley to investigate, and found that in the Huangya Valley in the south of Licheng County, Taihang Mountain, there is a natural cave, which is the Huangya Cave.

Huangya Cave is located in the middle of the mountain, surrounded by mountains on all sides, dangerous peaks and cliffs, only there is a crack in the south, called a line of sky, can enter and exit three or four people side by side, and the narrow place can only allow two people to pass.

The commander-in-chief and deputy commander-in-chief of the Eighth Route Army, as well as the chief of staff of the former commander, believed that this place was not only hidden, but also that the mountain was dangerous, and that the outer entrance of Huangya Cave was small and the inside was very hollow, so they immediately decided to move the headquarters arsenal to Huangya Cave.

The Huangyadong Arsenal has developed into an arsenal that produces more than 500 rifles and a large number of guns and ammunition per month, and can also repair mortars.

The deputy commander-in-chief of the Eighth Route Army, who was inspecting various battlefields, learned that the Weng Lang Heights were in danger of being held and that the Japanese troops had entered the Huangyadong Valley, and the deputy commander-in-chief not only shouted angrily: "Order that the responsibility of the commanders who evacuated the Weng Lang Heights without authorization be strictly investigated and punished by military law." ”

In order to protect the safety of the Huangyadong Arsenal, the deputy commander-in-chief ordered the 772nd Regiment and the 16th Regiment of the 386th Brigade to quickly reinforce Huangyadong and repel the Japanese devil troops who entered the Huangyagou Valley.

At this time, the Huangyadong factory area is surrounded by mountains, and the outside world can communicate with the outside world in addition to a line of sky, and then there is a small road to climb to the top of the mountain, and after going down the mountain, you can go directly to the headquarters of the Eighth Route Army in Wangjiayu, Wuxiang County.

Along a passage down the valley, there is a narrow mountain stream at the exit of the mountain pass, which winds and turns, and it is easy to get lost if you are not familiar with the road.

Along the narrow mountain stream sheep intestine path that is thousands of meters deep, go outward, two cliffs, two sides of the peaks are connected, from the crack into the deep stream of a line of light, only to see a line of sky, this is the dangerous line of the sky corridor.

At the promenade below the first line of the sky, a wide waterfall plummets straight down to a thousand feet, and the flowing water continues all year round.

The Eighth Route Army Headquarters Arsenal built in Huangya Cave, in order to facilitate access and to prevent the enemy puppet army from waiting for an opportunity to enter, a suspension bridge was erected in the first-line heavenly corridor, and the suspension bridge was lowered to pass, so that you could go out of the mountain stream to Liaoxian, Shexian, and Lucheng outside the mountain.

Once the enemy is discovered, immediately put away the suspension bridge, the road breaks the cliff, block the foreign enemy, it is difficult for the enemy to pass through the waterfall and enter the Yellow Cliff Cave.

Built on the periphery of the factory outside the cave, each entrance and exit is fortified with two blockade lines and three minefields, and it is difficult for the enemy to directly enter the factory through the minefields and two blockade lines.

In order to ensure the safety of the equipment in the factory area, there is a secret passage dug in the plant area, and once the enemy attacks, it will immediately pass through the underground passage to quickly withdraw the machinery and equipment and technicians, as well as soldiers and workers into the Huangya Cave.

If the enemy breaks through the blockade line and minefield of the factory, the commander will immediately evacuate the equipment and personnel to the top of the mountain through the secret passage in the cave, and then transport the equipment to the cave dug in advance along the small road leading to Shexian, Liaoxian, and Lucheng.

At the main peak of Huangya Mountain, which is more than 2,000 meters away, the arsenal has built strong fortifications, deployed three-layer firepower positions, and condescendingly attacked the attacking enemy who stepped into the factory area.

The Eighth Route Army's Huangyadong Arsenal, although very hidden, was still informed by the Japanese North China Front Headquarters, and sent troops to reconnoiter and harass many times, and the former deputy commander-in-chief of the Eighth Route Army Headquarters was the second time that the Japanese army stepped into the narrow mountain stream of Huangya Mountain, and in order to ensure the safety of this important military base, the 772nd Regiment and the 16th Regiment were ordered to reinforce quickly.
