1945: One of the largest Seabee stevedore assault operations in the Second World War was handled by 11th Special NCB at the invasion of Okinawa. The assignment began in February 1945 when the battalion was joined by two base companies of untrained personnel. Indoctrination of these recruits in the Seabee stevedore tradition, “keep the hook moving,” was started immediately. The big battalion was split into two divisions of nine nine-man teams each. The divisions separated, each going to a different staging area where the 18 teams were assigned to 18 different assault ships. Once at the staging area, each team loaded its assigned vessel and then rode that vessel to Okinawa. When the ships arrived off the coast of Okinawa on April 1, 1945, they were spread the entire length of the northern beaches. These were the beaches hit by the Third Amphibious Marines. Once landed, the Seabees unloaded on a 24-hour basis. Unloading was performed under extremely hazardous conditions. Enemy air raids persistently hammered at the shipping. Fourteen casualties were suffered by the 11th Special NCB during the early stages of the campaign. On the day after the invasion, April 2, 1945, six cranes, five bulldozers and a number of floodlight trailers were on the beaches as far north as Nago on the still bitterly contested Motobu peninsula. When the discharge of assault cargo was completed, the Seabee stevedores had a lull of about a week before the second echelon of supply ships arrived. However, during this week the men were not idle. They did excavation and construction work, roughed in roads and helped install anti-aircraft emplacements. Despite the week-long pause in stevedoring and the reduction of working time due to air raids, the end of April saw more than 70,000 tons of ammunition, guns, vehicles and supplies safely ashore and in the hands of the swift-moving assault forces.
