1stLt Smith assaulted Guam with the 1st Division, 4th Marines on 21 July 1944. Moving his mortar platoon up from the beach in the rear of advancing riflemen, 1stLt Smith observed a wounded rifleman lying close to a hostile pillbox and, halting his men, fearlessly advanced to the aid of the Marine under a continuous barrage from the Japanese emplacement. Engaging the enemy with rifle fire and hand grenades, he held his position despite the fierce opposition and attempted to neutralize the pillbox with a flame-thrower but, failing in this, continued to move up on the enemy while firing his rifle and, although mortally wounded during the bitter hostilities, succeeded in silencing the hostile gun-battery. By his determined initiative, valiant fighting spirit and resolute fortitude in the face of terrific odds, 1stLt Smith contributed materially to the ultimate success of our forces in recapturing this vital stronghold, and his unwavering devotion to duty throughout was in keeping with the highest traditions of the United States Naval Service. He gallantly gave his life for his country.

1stLt Smith was posthumously presented the Navy Cross.
