After the end of the third campaign to resist the United States and aid Korea, our volunteer army began to organize the fourth battle quickly, and the first place they chose to attack was Hengcheng, where they invested 13 divisions. That night, 10 divisions of the Volunteer Army launched an attack on the Korean army in Hengcheng, launching a full-scale night raid
By the next morning, the ROK positions were already surrounded by volunteers, and in this case the U.S. army ordered a retreat, but a regiment of the ROK 3rd Division was surrounded on the north side of Hoengseong, and only a small part of the troops retreated to where the U.S. troops were. By the 13th, the various troops on the front line began to be confused and wanted to retreat, and in a public historical record in the United States, it is recorded that the coalition troops began to disintegrate, and everyone began to panic and want to retreat, but the road was blocked, and as the battle became more and more intense, more and more corpses were piled up.
On the left side of the mountain, Northern Goryeo's legions also began to step in and launch a fierce encirclement offensive against the Allied forces, while the volunteers who had already captured Hengcheng on the other side continued to advance south and launched an attack on Wonju, a brutal battle that lasted until April, and the American coalition suffered heavy casualties in the war.
