1967: NMCB 11 was holding a change of command ceremony at the Dong Ha Forward Combat Base in Vietnam, which had been dedicated to the memory of Senior Chief Equipment Operator Donald J. Barnes, who had been killed in action at Khe Sanh. During the ceremony, attended by many senior naval officers and distinguished guests, a reception for the new commanding officer usually followed a change of command ceremony, but in this case, the custom had to be set aside. Barely half an hour after the ceremony began, enemy forces dropped about five mortar rounds onto the base. After the first round exploded, members of the battalion and visitors ran for the nearest hole. This is significant because it undoubtedly was the first time that a Seabee brigade commander, Captain Albert Marschall, CEC, and six of his battalion commanders shared the same mortar hole during an enemy artillery attack. Thankfully, there were no casualties.
