Pfc. Roger Spradley of Stuart, Fla., and E Company, 2nd Battalion, 26th Marines, writes home during a break from guarding U.S. Navy Seabees who are rebuilding a bridge (in the background) on Route 1 between Phu Loc and Lang Co in South Vietnam's coastal lowlands. The previous bridge had been destroyed by Viet Cong shelling, and attacks continued during the reconstruction effort.
