For extraordinary heroism in action against enemy forces on Saipan, Marianas Islands, while attached to a Marine rifle company. On 2 July 1944, Sergeant Monges was serving as sergeant guide in the first platoon of his company. Shortly after the company had started to move forward in an attack, his platoon was fired upon from several cleverly concealed enemy gun emplacements which threatened to destroy two squads of the platoon. Sergeant Monges quickly realized the peril in the situation and immediately took action to destroy the ambush. He dragged a seriously wounded automatic rifleman out of the path of fire of an enemy machine gun and into a position where he could be rendered first aid. He then took the automatic rifle himself and, in spite of the intense machine gun and rifle fire from the emplacements, worked his way to a position from which he could deliver devastating fire upon the enemy. With complete disregard for his own safety, he continued to fire upon the Japanese until the other members of his platoon could maneuver into positions to aid him. The platoon quickly took advantage of his splendid example of leadership, and also of the breach which he had created by destroying the nearest machine gun nest, and rapidly annihilated the enemy. The outstanding courage and devotion to duty displayed by Sergeant Monges was highly instrumental in making possible the successful attack against the enemy. His heroic actions are in keeping with the highest traditions of the United States Naval Service.

Major Monges resided in Central California. Mr. Monges was the Principal Founder & Director, Legion of Valor Museum.
