[17] Jenkins was assigned to command IX Corps in Korea, receiving promotion to lieutenant general and serving until he was wounded, after which he was evacuated to the U.S. to recuperate.

In October 1952, Jenkins led a successful counterattack in the Chorwon Valley to defeat a North Korean attack, for which he received the Distinguished Service Cross.

Despite the extreme dangers from intense and continuous enemy artillery and mortar fire, General Jenkins remained in the danger area and served as a constant inspiration to his subordinate commanders and soldiers throughout the first phase of the battle, during which the friendly troops fought the superior and fanatical enemy to a standstill.

After the enemy attack was successfully stopped, General Jenkins remained in the battle area, prepared and launched a counterattack.

The skillful leadership and prolonged outstanding demonstration of personal courage shown by General Jenkins under extremely hazardous conditions constituted vital elements in the successful conclusion of the battle.
