1967: At a dedication ceremony, the NMCB 9 campsite was named in honor of Utilitiesman Plumber 2nd Class James Miller, who was mortally wounded on February 6, 1967.
1943: The Seabees introduced their secret weapon on the beaches of Sicily: the famed magic boxes, steel pontoon sections which revolutionized the strategy of amphibious warfare. The German and Italian defenders were dug in along the northern coastline of Sicily where the best beaches were located. There was only one thing wrong with the German strategy. They had not heard of the new development for joining pontoons to form invasion causeways. Capt. John N. Laycock, CEC, developed a method to join pontoons together by angle iron and bolting pads so that a string of these connected pontoons became a solid structure of cantilevered integrity. On July 10, 1943 the Allied armada appeared off the southern coast between Scoglitti and Licata, and sent infantry ashore across long strings of steel pontoons. Other pontoon structures constructed by the Seabees included the rhino ferry and the landing tug. Each was made by simply putting together a couple dozen pontoons and an outboard motor.
1945: The 6th Special Naval Construction Battalion (NCB) inactivated at Oahu, Hawaii.

1958: When dissident elements in Lebanon threatened to overthrow the government of that country, the U.S. 6th Fleet cruising in the Mediterranean was sent to Beirut to establish and maintain order, at the request of the Lebanese government. Seabees of Amphibious Construction Battalion (ACB) 2 attached to the fleet participated in the action with their pontoon causeways when U.S. Marines landed, and again when the Marines re-embarked several months later. The men of ACB 2 not only participated in the landings, but the battalion’s Beach Salvage Teams also reclaimed broached boats and swamped vehicles, and improved beaches and roads. In addition, the Seabees in Lebanon built a road from the beaches to the Beirut airport.
1944: ACORN 10 was decommissioned. (Used during World War II, an ACORN was a tailored unit designed to carry out the rapid construction and subsequent operation of a landplane and seaplane advance base. Each ACORN had a construction battalion attached to it, as well as trained personnel to operate the control tower, field lighting, aerological unit, transportation, medical, berthing and messing facilities. A Construction Battalion Maintenance Unit (CBMU) also accompanied each ACORN to maintain the base after the initial construction was completed and the construction battalion had been withdrawn. During the war, ACORNs were sent to such places at Guadalcanal, Espiritu Santo, Green Island, Rendova, Treasury Island and Majuro.)
