The President of the United States of America takes pleasure in presenting the Silver Star to Private First Class John H. Alseth (MCSN: 1089628), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Rifleman of Company D, Second Battalion, Seventh Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 11 March 1951. When his platoon was subjected to withering hostile automatic weapons and small arms fire, which temporarily halted their advance, while participating as the assault element during a company attack against a heavily fortified enemy hill position, Private First Class Alseth, realizing the seriousness of the situation when attempts at eliminating a particularly large enemy bunker failed, moved forward through intense hostile fire with an armload of hand grenades and, reaching the bunker despite the heavy fire concentrated on him, skillfully hurled grenades into the apertures. Moving to another position, he dropped grenades into the connecting tunnels, thereby effectively denying their use to the enemy and rendering the positions untenable. Continuing his daring and aggressive actions, Private First Class Alseth succeeded in killing four of the enemy soldiers and wounding several others before he, himself, sustained serious wounds. By his valiant fighting spirit, resourceful initiative and unyielding devotion to duty in the face of extreme peril, he served to inspire all who observed him and upheld the highest traditions of the United States Naval Service.
