NOTES
(1) Even before Pearl Harbor, the War Plans Division (WPD) occasionally produced maps, such as this, presenting a tabulation of Army strength in the overseas bases. On 3 January 1942, WPD began regularly to issue a Weekly Status Map, showing the current and projected area. These maps were continued by WPD’s successor, OPD, until the fall of 1944 (for example, Charts 2 and 3). The data contained in these maps did not necessarily correspond with other statistical records kept in Washington or in the field. But this simplified accounting was the most reliable rough summary on Army deployment readily available to General Marshall and the whole War Department for planning purposes. See Cline, Washington Command Post: The Operations Division, pp. 87, 129-30.
(2) Figures shown as “After 1941” and “War” in Chart 1 are predictions for the end of 1942.
(3) Dashes (--) in columns indicate “Unknown.”
