A history of the Water Resources Branch of the United States Geological Survey: volume 4, years of World War II, July 1, 1939 to June 30, 1947

January 1, 1939

This period extends from July 1, 1939, to June 30, 1947, and is called the years of World War II, although it was not until December 1941 that the United States entered the war which began in Europe in September 1939. By the beginning of the period, it was evident that this country might be drawn into the conflict and a rearmament program including the draft act , effective in September 1940, was started and prosecuted vigorously prior to December 1941, when the attack on Pearl Harbor forced us into the war. Although the war was not officially ended by June 1947, President Truman proclaimed the end of hostilities on December 31, 1946, thus terminating some of his war-time powers, and by further action terminated other war-time powers as of June 30, 1947.
