On August 30, 1928, part of the 31st Regiment of the Red 4th Army, which was left in the Jinggangshan base, adopted tactical means of combining virtual and real and combining offense and defense with the support and cooperation of the 32nd Regiment and the support of the general public, and used dangerous measures to defend the Huangyangjie, and carried out painful, fierce and clever attacks on the four regiments of the Kuomintang army in Hunan and Jiangxi. The victory of the Huangyangjie defense battle created conditions for the main force of the Red 4th Army to subsequently break the second "suppression" of the Kuomintang army and restore the Jinggangshan base.

  Be firm in confidence and be fully prepared. In mid-August 1928, after the end of the first anti-"consensus" campaign, the Hunan-Jiangxi Border Special Committee of the Communist Party of China considered that the main troops of the enemy's "consensus" army were still stuck in or around the Jinggangshan base area, and the possibility of launching a new "consensus" in the near future still exists. In order to reverse the struggle situation in the base area, Comrade Mao Zedong decided to lead the 3rd Battalion of the 31st Regiment of the Red Army to go out of Guidong and take back the 28th Regiment; the first part of the 31st Regiment and the 1st and 2nd Battalions of the 32nd Regiment were left in Jinggangshan.

  In late August, after exploring the information that the Red Army heading to eastern Guizhou had not returned and Jinggangshan had weak defense forces, the commander of the 8th Army of the Kuomintang believed that the time for the invasion was ripe, and then he conspired with the commander of the 3rd Army of the Gan Army to "suppress". The Kuomintang troops of Hunan and Jiangxi dispatched 7 regiments of troops, of which 4 regiments pointed directly at Huangyangjie.

  Huangyangjie is located north of the main peak of Jinggangshan, with a dangerous road across the mountain. It is one of the five major sentries of Jinggangshan and is the only way for the Kuomintang army to invade Jinggangshan.

  After learning about the enemy's invasion, Zhu Yunqing, Party Representative He Tingying and others kept in mind the spirit of Comrade Mao Zedong's instructions on sticking to Jinggangshan before leaving. On the basis of comprehensive analysis and comparison, "the enemy soldiers are more equipped, the coming of fiercely, the people are few, the weapons are poor, and the defense is relatively difficult" and other favorable conditions such as "I have a advantage in geographical advantages, a good mass base, and the people's support is strong", they strengthened their confidence in defending the Jinggangshan base area, and put forward the battle slogan of "swearing to stick to Jinggangshan to the death and living with the five wells of big and small" to unify the will of the troops, and determined to use the main force to block the enemy with natural dangers at the Huangyangjie threshing and harass and restrain the enemy with some forces.

  Afterwards, the troops immediately set out preparations to meet the enemy. The 1st Battalion of the 31st Regiment, which was responsible for the main combat mission, entered the Huangyangjie sentry position overnight and built five defensive fortifications that supported and connected with each other with bamboo nail arrays, bamboo fence barriers and wire mesh, stone rolling wood, trenches, trenches and bunkers. The troops went deep into various villages to mobilize the masses widely, mobilized the military and civilians to work together to carry out operations such as inserting bamboo nails, lifting stones, carrying wood, and digging trenches. They organized the Red Guards, riots and revolutionary masses to urgently produce weapons and equipment such as pine cannons, land mines, and actively raid and restrain the enemy through guerrilla methods. At the same time, the 32nd Regiment quickly seized the remaining four whistles and prepared to fight against the invading enemy and defend Jinggangshan.

  Wait for work with ease and annihilate the enemy in close combat. On the morning of August 30, two regiments of the Kuomintang Hunan Army approached the Huangyangjie whistle under the cover of thick fog. Affected by the steep mountains, narrow mountain roads and fortifications, the enemy can only adopt a fish-style scattered line crawling after fire reconnaissance. After passing the first bamboo nail and opening the gap in the second bamboo fence wall, the invading enemy is exhausted and exhausted. Zhu Yunqing seized the favorable opportunity of the enemy's slow crossing obstacles and climbing up carefully, and urgently ordered the 1st Battalion, which was waiting to work, to carry out a sudden and fierce attack on the enemy close to the position. When the enemy reacted, it was too late to hide, and the wood and stone that "fall from the sky" quickly broke into the enemy's formation. For a time, the attacking enemy's attack formation was chaotic, and a large number of enemy troops were smashed by wood and stones, bleeding from their heads and broken legs and arms. Seeing that the enemy was not in good condition, he fled everywhere, and hurriedly fell into the bamboo nail formation, with heavy casualties, and retreated continuously in a wail.

  Subsequently, the Hunan Army organized two attacks in a dense formation. In the absence of ammunition, the 1st Battalion of the 31st Regiment fully relied on Huangyangjie natural dangers and fortifications, and conquered the enemy with rocks and rolled wood to hit the attacking enemy. The invading Hunan Army retreated after leaving behind a large number of corpses.

  Attack the key points and retreat to the enemy. At around 16 o'clock, the enemy decided to take a desperate bet. First, they concentrated all their firepower to bombard and suppress the fortifications of the 31st Regiment's defensive position, and then rushed towards the Huangyangjie sentry position in a dense formation like an ant colony. Faced with the powerful enemy's offensive, Zhu Yunqingxun was about to transfer the spy company responsible for the general reserve team to the position to enhance defense, and at the same time mobilized a newly repaired mortar with only 3 shells. Although the artillery soldiers of the 31st Regiment carefully measured the shooting distance and fired calmly, the first two shells fell into the enemy group and became duds. When the officers and soldiers were extremely anxious, the only remaining last shell happened to accurately hit the enemy command post. In an instant, dozens of enemy troops were killed and injured. With a sound of cannon, the enemy's command post was removed, scaring the enemy's courage, causing the enemy's morale to be in chaos.

  The 31st Regiment took the opportunity to start a full-scale counterattack. In an instant, the defensive officers and soldiers at the Huangyangjie whistle, rioters and local people cooperated closely, and wood and stones on the positions were fired, gunfire and red flags were everywhere, creating a powerful momentum for the main force of the Red Army to return to Jinggangshan. The rock rolling wood poured down towards the enemy formation, and grenades exploded among the enemy group. The enemy army, who did not know the truth, immediately panicked and fled in a hurry. The Red Army soldiers and rioters at the Huangyangjie whistle took advantage of the situation to raise bayonets and wave the darts, and rushed towards the enemy like a tiger going down the mountain. The enemy troops who were already fleeing all over the world saw the situation and had no fighting spirit, and rushed to throw away their weapons and equipment and fled in a hurry. That night, the terrified and invading enemy took advantage of the dense clouds and mist in the mountains and retreated from the Jinggangshan base overnight.

  While the 31st Regiment was hitting the enemy who was invading Jinggangshan base at the Huangyangjie whistle, the 2nd Battalion of the 32nd Regiment, the Red Guard and other forces, while closely monitoring the movements of the invading enemies, flexibly adopted offensive operations such as "taking advantage of the opportunity to approach Suichuan to force the enemy to withdraw troops and rescue, and repeatedly attacked along the way to disrupt and delay", actively undermining the enemy's joint "suppression" scheme, causing all enemy troops to be exhausted and frightened. After learning about the Hunan Army's crushing defeat, the Gan Army had to escape overnight.

  The remaining troops in Jinggangshan base area defeated the crazy attacks of several times their enemies within one day, winning the victory in the battle to defend the Huangyangjie. This battle slammed the strong momentum of the joint "suppression" between the Kuomintang Hunan and Jiangxi armies, and greatly boosted the morale of the military and civilians in the Jinggangshan base area. On the way back to Jinggangshan, Comrade Mao Zedong happily heard the news of the victory of the Huangyangjie Defense War and wrote "Xijiangyue·Jinggangshan": "The flags at the foot of the mountain are in sight, and the drums and horns on the top of the mountain are heard. The enemy's siege is numerous, and I remain unmoved. I have already been tightly blocked and have become more united. The sound of cannons in the Huangyangjie is loud, and the enemy's escape is reported at night."
