The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Silver Star to First Lieutenant (Infantry) Mario Estrada (ASN: 0-2033790), United States Army, for conspicuous gallantry and intrepidity in action while serving with Company E, 8th Cavalry Regiment, 1st Cavalry Division, in action against the enemy on 4 February 1951 near Chayang-ni, Korea. Lieutenant Estrada and his platoon were under orders to attack and seize Hill 30. As the platoon advanced upon their objective, the enemy opened fire on them with machine guns and small arms. Lieutenant Estrada immediately ordered his platoon to attack and placed his machine gun where it would provide the most effective overhead fire. He then assumed the lead position, inspiring and encouraging his men to such an extent that the enemy was routed from his positions with heavy casualties. After the positions had been secured, the enemy immediately launched an overwhelming counter-attack which momentarily set Lieutenant Estrada’s platoon back. Lieutenant Estrada again, without any regard for his personal safety, led his platoon against the enemy, personally killing four enemy soldiers with hand grenades. By his actions, the platoon successfully beat off the enemy attack, and the hill was secured. Lieutenant Estrada’s performance of duty with gallantry set a very high example for his men and inspired them to such an extent that this difficult mission was accomplished even in the face of overwhelming enemy numbers. His gallantry reflects great credit on himself and the military service.
