The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to Private Arnold Lee Sardeson (ASN: US-55209325), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving as a Medical Aidman with an Infantry Company of the 224th Infantry Regiment, 40th Infantry Division. Private Sardeson distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Mandae-ri, Korea, on the night of 1 May 1953. On that date, Private Sardeson was Aidman for a United Nations patrol that was forced to withdraw under an intense enemy mortar and artillery barrage. Upon hearing the cries of men wounded in the action, he voluntarily left his bunker and went to their aid. He treated one man and carried him back to the main line. With no thought of his own safety, Private Sardeson returned to forward area, treated a second comrade, and evacuated him to the rear. Noticing a wounded Korean soldier lying completely exposed to the enemy barrage, Private Sardeson again braved the heavy incoming fire and ran to his assistance. While treating the third United Nations soldier Private Sardeson was killed instantly by an enemy mortar round. Through his courageous self-sacrifice and unflinching devotion to duty, he personally saved the lives of two comrades. The extraordinary heroism displayed by Private Sardeson on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
