The formation of the Seabees before March 5
On December 28, 1941, Rear Admiral Ben Moreell, Chief of the Bureau of Yards and Docks (BUDOCKS), requested specific authority to activate, organize, and man a unique, very special organization that would support the Navy and Marines in remote locations and defend themselves if attacked — the Naval Construction Battalions. On January 5, 1942, he was given that authority and the original Battalions were formed at a new Naval base in Davisville, Rhode Island.
The first naval construction unit to actually deploy from the United States left Davisville, Rhode Island, less than two weeks later on January 17, 1942. It was designated the First Construction Detachment. The 296 men arrived at Bora Bora on February 17, 1942.
On March 5, all Construction Battalion personnel were officially named Seabees by the Navy Department. Admiral Moreell personally furnished them with their motto Construmus Batumius, or We Build, We Fight. A logo, the Fighting Bee, was created by a Rhode Islander at Davisville.
1942: The designation of construction battalions as Seabees and the use of the distinctive insignia on major items of construction equipment were officially approved by Rear Adm. Ben Moreell.
1955: It was in 1955 that the Seabees first celebrated their birthday on March 5. Before that the birthday had been celebrated on December 28, the date in 1941 that authority was requested from the Chief of the Bureau of Navigation to recruit enlisted personnel for the Seabee units. However, because so many men were usually on leave for the Christmas holidays and because of the heavy financial strain that attended the holidays, it was almost impossible for everyone to participate in a suitable celebration. Therefore, Rear Adm. John R. Perry, Chief of the Bureau of Yards and Docks, decided to change the celebration date to March 5, the date the personnel of the construction battalions were granted official permission to assume the name Seabees. Rear Adm. Perry felt this would assure a more favorable observance of the birthday.
