The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting the Soldier’s Medal to First Lieutenant (Corps of Engineers) Robert William Siemer, United States Army, for heroism at the risk of life not involving conflict with an armed enemy, in the Republic of Cambodia on 22 May 1970. First Lieutenant Siemer distinguished himself by heroism while serving in the Republic of Cambodia. After setting the charged to detonate, First Lieutenant Siemer noticed a helicopter was in-bound to the fire base and was heading to the area in which the demolitions were set to explode. He rushed back to the area with a demolitions specialist to insure the charges were disarmed, but as the specialist was about to cut the fuse the demolitions exploded and injured the two of them. His concern for the welfare of his fellow soldiers and devotion to duty was in keeping with the highest traditions of military service and reflects great credit upon himself, his unit, and the United States Army.
