The main campaign to resist U.S. aggression and aid Korea-Shangganling campaign
19521June 14, the US military launched an attack on the positions defended by the Volunteers 15 Army in Shangganling area. The battle lasted for 43 days and went through three stages: in the first stage, the two sides fought fiercely around two highland water positions; In the second stage, the surface position was occupied by the US military, and the volunteers launched tunnel warfare with the enemy. In the third stage, the volunteers launched a decisive counterattack to force the enemy to stop attacking. In the Battle of Shangganling, volunteers killed or injured more than 25,000 prisoners.
Comments: The Battle of Shangganling is the most intense battle in the positional warfare stage. Relying on the tunnel and supported by deep artillery fire, the volunteers successfully resisted the continuous onslaught of the enemy with superior forces and firepower, creating an example of insisting on defensive operations in the history of modern war. The victory of Shangganling campaign indicates that the volunteers have completely mastered the initiative of the whole frontal battlefield. Since then, the "United Nations Army" has never launched a large-scale attack.

1in June, 953, just as the parties were preparing to sign the armistice agreement, Li Chengwan deliberately destroyed the negotiation agreement in the early morning of June 18. In order to ensure the stability of the situation after the armistice in Korea, our army decided to fight again and selected the position of the South Korean army south of Jincheng as the target of attack. On July 27th, the fighting ended. In the Battle of Jincheng, the Volunteers annihilated 53,000 enemies and consolidated the occupied position of 160 square kilometers.
Comments: The Battle of Jincheng was the last battle of the War to Resist US Aggression and Aid Korea. This campaign is the only battle-scale position offensive operation carried out by the volunteers in the whole war, and it is a pioneering operational practice in the history of our army. The campaign carried out the guiding principle of "slow but steady", concentrated superior forces and firepower, and formed a powerful offensive force. The victory of the campaign ensured the stability of the situation after the Korean armistice.
