CINCPOA Communiqué No. 277
Elements of the 3rd, 4th and 5th Marine Divisions made substantial advances along the whole northern sector on Iwo Island on February 24 (East Longitude Date). Their attack was made in the face of intense fire from heavy weapons and rockets but it carried northward generally about 308 to 500 yards through a maze of interlocking, or mutually supporting concrete pillboxes, blockhouses and fortified caves. All areas crossed were heavily mined. By 1800, our units had reached the middle area of the central Iwo airfield, had pushed forward several hundred yards on the west and had begun a drive which expanded our beachhead northward along the east coast about 600 yards.
In every zone of the fighting, the enemy resisted our advance to the full extent of his armament. Weapons of the “bazooka” type were employed against our tanks and the use of rocket bombs, weighing about 500 kilograms, continued. Enemy positions in the area through which our units advanced were generally reinforced blockhouses and pillboxes with four‑foot bulkheads. In a single area of about 400 by 600 yards on the east coast, our forces neutralized about 100 caves between thirty and forty feet deep.
An immediate result of the advance was apparent in a marked decrease of enemy artillery fire into the interior of the area under our control.
The attack was supported by marine artillery and by fire from heavy units of the fleet standing off Iwo Island. Carrier aircraft continued their close support of the troops and also made an attack on Chichi Jima in the Bonins.
In the south, Marines continued their mop-up of enemy strongpoints in and around Mount Suribachi. Incomplete reports indicate that 115 enemy emplacements have been destroyed in that sector.
A total of 2,799 enemy dead have been counted on Iwo Island.
The condition of the beaches showed marked improvement and unloading of supplies was accelerated.
Seventh Army Air Force bombers of the Strategic Air Force, Pacific Oceans Areas, bombed the airfield and Omura town on Chichi Jima and Okimura town on Haha Jima in the Bonins on February 22.
