The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Sergeant Silvio Sanguedolce (MCSN: 275762), United States Marine Corps, for extraordinary heroism and conspicuous devotion to duty while serving as Forward Observer for a Mortar Platoon with the Third Battalion, First Marines, FIRST Marine Division, during action against enemy Japanese forces in the Matanikau River Area, Guadalcanal, Solomon Islands, on the night of 23 October 1942. When heavy enemy fire disrupted communications and caused serious casualties among members of the half track crew, Sergeant Sanguedolce risked his life to help in reestablishing lines and by his skillful and determined efforts enabled his Mortar Platoon to resume operations. Returning to his post, he fearlessly exposed himself to hostile fire and continued his dangerous task of observing the fire of his platoon until he was killed by the enemy. He gallantly gave up his life in the service of his country.
