On this day 97 years ago, August 30, 1928 (July 16, 1928 in the lunar calendar), the Battle of Huang Yangjie was fought. "The sound of cannons on Huang Yangjie was loud, and it was reported that the enemy had fled in the night". This is a verse by Mao Zedong describing the scene of the Battle of Huang Yangjie in the words "Xijiangyue ¡¤ Jinggangshan". The Battle of Huang Yangjie was a battle in which the Fourth Army of the Chinese Workers and Peasants' Red Army defended the Jinggangshan Revolutionary Base during the Second Domestic Revolutionary War. Huangyangjie is located on The North Face of Jinggangshan, with an altitude of more than 1,300 meters. It is one of the dangerous outposts of Jinggangshan. In August 1928, Zhu De led the main force of the Fourth Army of the Red Army to southern Hunan, and Mao Zedong led a part of the Red Army to Guidong to meet the main force of the Fourth Army of the Red Army. Only a small number of troops were left in Jinggangshan, resulting in the emptiness of The enemies of the Hunan and Jiangxi provinces took advantage of the fact that the main force of our army had not returned, and launched a second "encirclement and suppression" against the Jinggangshan base area. On the morning of August 30, the first division of the Eighth Army of the Hunan enemy, with the support of the Jiangxi enemy, launched a fierce attack on the Huangyangjie position on Jinggangshan. The first battalion of the 31st Regiment of our army guarding Huangyangjie, led by the party representative He Tingying, with the support of the Red Guards and the masses, launched a fierce battle with the enemy on the dangerous terrain that was condescending from Huangyangjie. Due to the limitations of the terrain, the enemy's forces could only be in formation, climbing up one by one, and each force must maintain a certain distance, otherwise it would not be able to shoot. Therefore, although the enemy has the strength of one division, it can only use the strength of one battalion in the line of fire at most. The Red Army was arranged at the forefront by one platoon in a row, and the other two platoons were hidden behind the side, waiting for the opportunity to attack the enemy. The third company was resting at the back, preparing to replace the commanders and fighters of the first company. At that time, due to the lack of guns and ammunition, each soldier only had three or five bullets. In order to save bullets, the enemy did not fire when they were far away, and then suddenly opened fire when they were within the effective range. In this way, our army fought from morning to afternoon, repelling the enemy's many attacks. At about four o'clock in the afternoon, just as the enemy was reorganizing the attack, the soldiers brought up the only mortar that had been brought to Jinggangshan since the Nanchang Uprising, and fired three shells at the enemy, one of which was falling on the enemy command position When the enemy heard the sound of cannons, they thought that the main force of the Red Army had returned to Jinggangshan and did not dare to fight again. They took advantage of the opportunity of clouds and fog in the evening and fled. This battle killed and wounded more than 200 enemy troops. The Huang Yangjie defense battle successfully defended the Jinggangshan strategic base, creating conditions for the main force of the Red Fourth Army to return, break the enemy's second "encirclement and suppression", and restore the base area.
