For conspicuous gallantry and intrepidity while serving as Flame Thrower Operator of Company E, Second Battalion, Twenty-eight Marines, Fifth Marine Division, in action against enemy Japanese forces on Iwo Jima, Volcano Islands, from 19 February to 1 March 1945. Repeatedly exposing himself to hostile grenades and machine-gun fire in order that he might reach and neutralize enemy pill-boxes at the base of Mount Suribachi, Corporal Lindberg courageously approached within ten or fifteen yards of the emplacements before discharging his weapon, thereby assuring annihilation of the enemy and the successful completion of his platoon's mission. As a member of the first combat patrol to scale Mount Suribachi, he courageously carried his flame thrower to the steep slopes and assisted in destroying the occupants of the many caves found in the rim of the volcano, some of which contained as many as seventy Japanese. While engaged in an attack on hostile cave positions on March 1, he fearlessly exposed himself to accurate enemy fire and was subsequently wounded and evacuated. By his determinations in manning his weapon, despite its weight and the extreme heat developed in operation, Corporal Lindberg greatly assisted in securing his company's position. His courage and devotion to duty were in keeping with the highest traditions of the United States Naval Service.
