In 1967–1968, Charlie Battery, 1st Battalion, 13th Marines, operated as a mobile 105 mm howitzer unit in I Corps, supporting the 1st and 3rd Marine Divisions around Quảng Trị, Con Thien, and the DMZ under frequent enemy fire. During the Tet Offensive, the battery was pivotal in the Battle of Khe Sanh, delivering round-the-clock barrages under Operation Niagara to repel North Vietnamese assaults and secure supply routes. The siege, among the war’s heaviest artillery engagements, lasted until July 1968.
