Walton Walker
The division's 19th and 34th regiments had engaged the North Korean 3rd Infantry Division and the North Korean 4th Infantry Division between 13 and 16 July and suffered 650 casualties among the 3,401 men committed there. On 18 July, the Eighth Army commander, Lieutenant General Walton Walker, ordered General Dean to hold Taejon until the 20th so that the 1st Cavalry Division and 25th Infantry Division could establish defensive lines along the Naktong River, forming the Pusan Perimeter. As the North Korean push against the US units forced them back, 31 US troops were killed in the Chaplain-Medic Massacre.
