[Illustration: National Archives Photo 80-G-279375 _Ford Island, seen on 10 October 1941 from much the same angle as Japanese bomber pilots viewed it on 7 December._] Infamous Day: Marines at Pearl Harbor _by Robert J. Cressman and J. Michael Wenger_ On the afternoon of 6 December 1941, Tai Sing Loo, the colorful Pearl Harbor Navy Yard photographer, arranged with Platoon Sergeant Charles R. Christenot, the noncommissioned-officer-in-charge of the Main Gate at the Navy Yard, to have his Marines pose for a photograph between 0830 and 0930 Sunday morning, in front of the new concrete main gate. The photo was to be for a Christmas card. As war clouds gathered over the Pacific basin in late 1941, the United States Pacific Fleet operated, as it had since May 1940, from Pearl Harbor. While the security of that fleet and for the island of Oahu lay in the Army’s hands, that of the Navy Yard and the Naval Air Stations at Pearl Harbor and Kaneohe Bay lay in the hands of Marines. In addition, on board the fleet’s battleships, aircraft carriers, and some of its cruisers, Marines provided security, served as orderlies for embarked flag officers and ships’ captains, and manned secondary antiaircraft and machine gun batteries--seagoing duties familiar to the Corps since its inception. The Marine Barracks at Pearl Harbor comprised a Barracks Detachment and two companies, A and B, the men living in a comfortable three-story concrete barracks. Company A manned the main gates at the Submarine Base and Navy Yard, and other “distant outposts,” providing yard security, while Company B enforced traffic regulations and maintained proper police and order under the auspices of the Yard Police Officer. In addition, Marines ran the Navy Yard Fire Department. Elements of Marine defense battalions made Pearl Harbor their home, too, residing in the several 100-man temporary wooden barracks buildings that had been completed during 1940 and 1941. Less commodious but no less important was the burgeoning airbase that Marines of Marine Aircraft Group (MAG) 2 (later 21) had hewn and hammered out near Barbers Point--Ewa Mooring Mast Field, home for a Marine aircraft group consisting of fighting, scout-bombing, and utility squadrons.
