U.S. Navy Department (June 20, 1944)
CINCPAC Communiqué No. 57
U.S. Marines and Army infantrymen are continuing to advance on Saipan Island closely supported by aircraft bombing by Army and Marine artillery and naval gunfire against severe enemy artillery fire. Our troops now hold the entire southern portion of the island from the southern outskirts of Garapan across to the center of the western shore of Magicienne Bay. Several strong pockets of enemy resistance within this area are being heavily attacked by our forces.
During June 19 (West Longitude Date), the airfields on Tinian Island were bombed by our aircraft and shelled by our surface units.
