At 4 a.m. the North Koreans began an artillery barrage on the division's positions along the 38th Parallel. The artillery bombardment was quickly followed by ground attacks by the NKPA's 1st and 6th Infantry Divisions. It became part of II Corps after the first fall of Seoul, and was part of the defensive line to slow the North Korean advance from Seoul to Taejon. It subsequently fought in the Battle of Pusan Perimeter.http://www.history.army.mil/brochures/KW-Outbreak/outbreak.htm The Korean War: The Outbreak United States Army Center of Military History CMH Pub 19-6 William J.

The entire city was secured by 10:00 that day.http://www.history.army.mil/brochures/kw-unoff/unoff.htm The Korean War: The UN Offensive CMH Pub 19-7 Stephen L.Y.

The division's 15th Regiment passed through Yongbyon and continued toward Unsan without opposition. In the lead were elements of Company D, 6th Medium Tank Battalion, which also passed through Unsan without incident. Just before 1100, as the tanks approached a bridge one and a half miles northeast of the town, enemy mortar fire destroyed the bridge. Engaging the enemy force, the soldiers reported a half-hour later that at least three hundred Chinese troops were in the hills just north of Unsan. The 12th Regiment, the second division unit in the column, turned west when it arrived at Unsan, and also ran into Chinese forces just beyond the town. The CCF's attacks against the 1st Division continued on the twenty-sixth but eased up the following day."http://www.history.army.mil/brochures/kw-unoff/unoff.htm The Korean War: The UN Offensive 26 Stephen L.Y.

At nightfall the 1st Battalion controlled the northern approaches to the Samtan River, except for portions of the 15th Regiment's zone on the east side. The battalion's position on the left was weak; there were not enough soldiers to extend the defensive line to the main ridge leading into Unsan. This left a gap between the 1st and 2d Battalions. East of the Samtan the 15th Regiment was under heavy attack, and shortly after midnight it no longer existed as a combat force.http://www.history.army.mil/brochures/kw-unoff/unoff.htm The Korean War: The UN Offensive 27 CMH Pub 19-7 United States Army Center of Military History Stephen L.Y.
