　　During the Korean War, an American soldier was the first to be killed in action near Jochiwon on July 3, 1950. An American medic performed an autopsy on the corpse by elevating the head and taking the pulse. The battle of Jochiwon broke out from July 9 to July 11, and on July 8, the American troops retreated to Jochiwon after an urban battle developed in Cheonan City.

　At around 3 p.m. on July 9, a North Korean tank unit invaded the retreating Jochiwon position, and at 6 a.m. on July 10, the North Koreans sent a reconnaissance team ahead and fired heavily to confirm the deployment status of the American forces by whether they returned fire. They then launched a mortar attack. At 8:30 a.m., American soldiers were attacked by mortar positions in the rear. At 9:00 a.m., the North Korean forces began a full-scale attack. At 11:35 a.m., the North Koreans occupied the left side of the American battalion and attacked the front line and even the left rear. Mistakenly believing that the North Koreans were on the verge of falling or had fallen, the U.S. forces launched a furious fire on their own positions. American soldiers left their positions one after another. At 12:05 p.m., the U.S. troops finally decided to retreat and issued an order. They were ambushed as they carried mortar shells from Torichi-in to the outpost.

　At about 1:00 a.m. on July 11, American troops arrived at the 1st Battalion's position. North Korean troops and guerrillas entered the position. At 9:30 a.m. on July 12, a North Korean battalion attacked the left side of the American battalion amid supporting artillery fire and pushed in from the opposite side, disrupting the American battalion around noon. On July 12, the U.S. forces withdrew from Joriwon to the southern bank of Geumgang.
