Overview: The main content of this episode: On October 14, 1952, the 8th Group Army of the United States launched a fierce artillery attack on the Volunteer Army's position. This time, Vanfrett's attack target was the forward position of the Volunteer Army's central front south of Mount Wusheng, Shangganling, while his opponent was the brave and skilled Volunteer Army's 15th Army. This was one of the most brutal battles in the Korean War, and behind the struggle for every inch of land was the spirit of Chinese soldiers who dared to face strong enemies and sacrificed their lives.
