Smoke darkens the sky over the Marine Barracks complex at the Pearl Harbor Navy Yard; Marine in foreground appears to be holding his head in disbelief. Marines at far left in background appear to be unlimbering a 3-inch antiaircraft gun.
Meanwhile, the comparatively few Marines of Lieutenant Colonel Bert A. Bone’s 1st Defense Battalion—most of which garrisoned Wake, Johnston, and Palmyra—made their presence felt. Urged on by Lieutenant Noyes, one detail of men immediately reported to the battalion gun shed and storerooms, and issued rifles and ammunition to all comers, while another detachment worked feverishly assembling machine guns. Navy Yard workmen—enginemen Lokana Kipihe and Oliver Bright, fireman Gerard Williams, and rigger Ernest W. Birch—appeared, looking for some way to help the Marines, who soon put them to work distributing ammunition to the machine gun crews. Soon, the Marines at the barracks added the staccato hammering of automatic weapons fire to the general din around them. Meanwhile, other Marines from the 1st Defense Battalion broke out firefighting equipment, as shrapnel from exploding antiaircraft shells began to strike the roof of the barracks and adjacent buildings.
At about 0820, Majors Roberts and Benner reached the Marine Barracks just in time to observe the beginning of the Japanese second wave attacks against Pearl. Roberts found that Lieutenant O’Halloran had gotten the 3d Battalion ready for battle, with seven .50-caliber and six .30-caliber machine guns set up and with ammunition belted. Under Captain Harry O. Smith, Jr., commanding officer of Battery H, Machine Gun Group, 3d Defense Battalion, the 3d’s Marine gunners had already claimed one Japanese plane shot down. Lieutenant Noyes was, meanwhile, in the process of deploying seven 3-inch guns—three on the west end of the parade ground and four on the east.
Sergeant Major Leland H. Alexander, of the Headquarters and Service Battery of the 3d Defense Battalion, suggested to Lieutenant O’Halloran that an armed convoy be organized to secure ammunition for the guns, as none was available in the Navy Yard proper. Roberts gave Alexander permission to put together the requisite trucks, weapons, and men. Lieutenant Colonel Bone had the same idea, and, accordingly dispatched a truck at 0830 to the nearest ammunition dump near Fort Kamehameha. Bone ordered another group of men from the 5-inch battery to the Naval Ammunition Depot at Lualualei just in case. He hoped that at least one truck would get through the maelstrom of traffic. Marines from the 2d Engineer Battalion made ammunition runs as well as provided men and motorcycles for messengers.
Meanwhile, Roberts directed Major Benner to have the 3d Battalion’s guns operational before the ammunition trucks returned, and to set the fuzes for 1,000 yards, since the guns lacked the necessary height-finding equipment. The makeshift emplacements, however, presented less than ideal firing positions since the barracks and nearby yard buildings restricted the field of fire, and many of the low-flying planes appeared on the horizon only for an instant.
Necessity often being the mother of invention, Roberts devised an impromptu fire control system, stationing a warning section of eight men, equipped with field glasses and led by Lieutenant Swartz, in the center of the parade ground. The spotters were to pass the word to a group of field musics who, using their instruments, were to sound appropriate warnings: one blast meant planes approaching from the north; two blasts, from the east, and so on.
Taking precautions against fires in the temporary wooden barracks, Roberts ordered hoses run out and extinguishers placed in front of them, along with shovels, axes, and buckets of sand (the latter to deal with incendiary bombs); hose reel and chemical carts placed near the center hydrant near the mess hall; and all possible containers filled with water for both fighting fires and drinking. In addition, he ordered cooks and messmen to prepare coffee and fill every other container on hand with water, and organized riflemen in groups of about 16 to sit on the ground with an officer or noncommissioned officer in charge to direct their fire. He also called for runners from all groups in the battalion and established his command post at the parade ground’s south corner, and ordered the almost 150 civilians who had showed up looking for ways to help out to report to the machine gun storeroom and fill ammunition belts and clean weapons. Among other actions, he also instructed the battalion sergeant major to be ready to safeguard important papers from the headquarters barracks.

Prior to Roberts’ arrival, Lieutenant (j.g.) William R. Franklin (Dental Corps), USN, the dental officer for the 3d Defense Battalion’s Headquarters and Service Battery, and the only medical officer present, had organized first aid and stretcher parties in the barracks. As the other doctors arrived, Roberts directed them to set up dressing stations at each battalion headquarters and one at sick bay. Elsewhere, Marines vacated one 100-man temporary barracks, the noncommissioned officer’s club and the post exchange, to ready them for casualties. Parties of Marines also reported to the waterfront area to assist in collecting and transporting casualties from the ships in the harbor to the Naval Hospital.
By the time the Marines had gotten their new fire precautions in place, the Japanese second wave attack was in full swing. Although their pilots selected targets exclusively from among the Pacific Fleet warships, the Marines at the barracks in the Navy Yard still were able to take the Japanese planes, most of which seemed to be coming in from the west and southwest, under fire. While Marines were busily setting up the 3-inch guns, several civilian yard workmen grabbed up rifles and “brought their fire to bear upon the enemy,” allowing Swartz’s men to continue their work.
