Rouh had earlier earned a field commission and been awarded the Silver Star medal of gallantry during the Battle of Guadalcanal for action on October 9, 1942.
Carlton Rouh enlisted in the United States Marine Corps as a private one month after Pearl Harbor and fought in three Pacific campaigns.
First Lieutenant Rouh had been moving his mortar platoon near the top of a small coral ridge in preparation for digging in for the night, according to a field dispatch from SSgt James F. Moser Jr., a Marine Corps Combat Correspondent.
For these actions, Rouh was presented with the Medal of Honor by President Harry S. Truman at a White House ceremony on June 15, 1945, which included presentations to fellow Marine recipients Everett P. Pope and Luther Skaggs Jr., as well as Army recipient Gino J. Merli, for their heroism during actions in the Central Pacific and European theatres.
The President of the United States takes pride in presenting the MEDAL OF HONOR to for service as set forth in the following CITATION: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while attached to the First Battalion, Fifth Marines, First Marine Division, during action against enemy Japanese forces on Peleliu Island, Palau Group, 15 September 1944.
mortar observation post, First Lieutenant Rouh made a personal reconnaissance of the pillbox and, upon entering, was severely wounded by Japanese rifle fire from within.
Emerging from the dugout, he was immediately assisted by two Marines to a less exposed area, but while receiving first aid, was further endangered by an enemy grenade which was thrown into their midst.
Quick to act in spite of his weakened condition, he lurched to a crouching position and thrust both men aside, placing his own body between them and the grenade and taking the full blast of the explosion himself.
His exceptional spirit of loyalty and self-sacrifice in the face of almost certain death reflects the highest credit upon First Lieutenant Rouh and the United States Naval Service.
His heroic conduct, maintained at great risk in the face of grave danger, was in keeping with the highest traditions of the United States Naval Service.
