The banner of "Adhering to the Level 1 Hero Class of 202.9 Highland". In July 1952, during the spring and summer consolidation operations during the War of Resistance against the United States and Aid to Korea, the 4th Squadron of the 7th Company of the 343rd Regiment of the 115th Division of the 39th Volunteer Army was ordered to carry out the task of defending the unnamed highland in the east of 222.9. 222.9 East Nameless Highland is also known as Old Bald Mountain. This mountain, with an altitude of only over 260 meters, has a small area but a very important geographical location. It is not only an important commanding point in the enemy friendly buffer zone, but also a necessary path to Seoul (now Seoul). On July 18, 1952, Class 4 headed towards Old Bald Mountain by night. After entering the position, the 4th Squad actively repaired the fortifications and carried out rigorous camouflage. On the 21st, the enemy launched a fierce artillery attack on Old Bald Mountain, and Squad 4 quickly entered the tunnel to conceal and prepare for battle. At around 21:00, about 2 platoons of enemy troops used the rainy night to sneak attack the position of the 4th Squadron. As the enemy approached the forefront of our army, Class 4 squad leader Liu Zuo heard the sound of iron objects colliding nearby and judged that the enemy was sneaking towards me. The soldiers of Class 4 immediately jumped out of the tunnel and launched a fierce attack on the enemy. The enemy commander was killed on the spot. Taking advantage of the chaos, Liu Zuocai led the entire team to carry out a counterattack and, after a 2-hour fierce battle, annihilated more than 50 enemy soldiers, repelling the enemy's attack. On the early morning of the 22nd, a sudden sound came from the foot of the mountain, and the enemy army touched it again. The soldiers of Class 4 responded calmly and suddenly opened fire when the enemy entered a distance of 30 meters from the position, repelling the enemy's attack again. Machine gunner Wang Yi jumped out of the trench and bravely fired with his machine gun. After multiple injuries, he fell to the ground and threw grenades. More than 4 soldiers in the class may be seriously injured, unconscious, or sacrificed heroically. With the Fire support of the company and platoon, the 4th squad wiped out more than 200 enemy troops and held the position. The enemy's repeated attacks failed, and they became angry with embarrassment and began to carry out destructive bombings on Old Bald Mountain. At 5:30 on the 22nd, nearly one battalion of enemy troops, supported by planes, artillery, and tanks, launched a more intense attack on the 4th Squadron position, with 2 enemy squadrons advancing into the 4th Squadron position. Ni Xiangming, the deputy squad leader of the 4th Squad on the surface position, was fearless in the face of danger, leading soldier Zhou Yuande to cleverly use fortifications and craters as support, constantly changing positions to throw grenades at the enemy, and continuously repelling several small-scale attacks. With all the bullets running out, Ni Xiangming fired his last grenade and died with the enemy. When the enemy approached the tunnel, Liu Zuocai, who was heavily injured, organized the wounded to repel the enemy's multiple attacks and ultimately defended the tunnel. At dawn on the 23rd, our army's main force bravely counterattacked, recaptured the surface position and held on to the old bald mountain. In this battle, four squadrons of soldiers fought fiercely for four days and nights, repelling 13 enemy attacks more than ten times their own, annihilating more than 500 enemy soldiers, and firmly holding onto the strategic point of Old Bald Mountain. After the war, the headquarters of the Volunteer Army awarded a banner to the 4th class of "Level 1 Hero Class Adhering to the 202.9 Heights". For 71 years, this flag has become the soul and root of the hearts and feet of generations of soldiers from Class 4. On the road to building a strong military, they take inheriting the spirit of the battle flag as their own responsibility, actively participate in training and preparing for battle, and continuously continue to write new glories.
