For the forces of General MacArthur's Southwest Pacific Area the reconquest of Luzon and the Southern Philippines was the climax of the Pacific war. Viewed from the aspect of commitment of U.S. Army ground forces, the Luzon Campaign (including the seizure of Mindoro and the central Visayan Islands) was exceeded in size during World War II only by the drive across northern France. The Luzon Campaign differed from others of the Pacific war in that it alone provided opportunity for the employment of mass and maneuver on a scale even approaching that common to the European and Mediterranean theaters.
