The U.S. Navy suffered such high personnel losses during the campaign that it refused to publicly release total casualty figures for years. However, as the campaign continued, and the American public became more and more aware of the plight and perceived heroism of the American forces on Guadalcanal, more forces were dispatched to the area. This spelled trouble for Japan as its military-industrial complex was unable to match the output of American industry and manpower. Thus, as the campaign wore on the Japanese were losing irreplaceable units while the Americans were rapidly replacing and even augmenting their forces.
