Additional Information
Last Known Activity:
Grayback’s 10th war patrol, her most successful, was also her last. She left Pearl Harbor, 28 January, 1944, and by 25 February had sunk three ships and damaged three others. On 27 February she sank another ship but was apparently attacked by carrier based aircraft (according to Japanese reports) and sunk. Commander Moore was listed as Missing in Action and later declared dead 12 January 1946.

Description The plan of the Pacific subseries was determined by the geography, strategy, and the military organization of a theater largely oceanic. Two independent, coordinate commands, one in the Southwest Pacific under General of the Army Douglas MacArthur and the other in the Central, South, and North Pacific (Pacific Ocean Areas) under Fleet Admiral Chester W. Nimitz, were created early in the war. Except in the South and Southwest Pacific, each conducted its own operations with its own ground, air, and naval forces in widely separated areas. These operations required at first only a relatively small number of troops whose efforts often yielded strategic gains which cannot be measured by the size of the forces involved. Indeed, the nature of the objectivesùsmall islands, coral atolls, and jungle-bound harbors and airstrips, made the employment of large ground forces impossible and highlighted the importance of air and naval operations. Thus, until 1945, the war in the Pacific progressed by a double series of amphibious operations each of which fitted into a strategic pattern developed in Washington.
