World War II was fought between the Axis Powers (Germany in most of continental Europe, Italy dominating the Mediterranean Sea, and Japan throughout East Asia and the Pacific) and the Allied Powers (United States, Great Britain, Soviet Union, France, and China). Involving over 30 countries, about 70 million people were killed during World War II. The Allies defeated Nazi Germany and Japan in 1945, bringing the largest and deadliest war in human history to an end.

From January to June 1944, the U.S. Army 622nd Air Warning Signal Company was stationed at the Dade Battlefield Historic State Park, which was then called Dade Memorial Park. This contemporary sketch, drawn by one of the men stationed there, shows a number of tents, mess hall, supply room, shower room, and motor pool, stretching south, east and north from the area of the breastworks on the 1835 battle site. Other structures were peppered throughout other nearby areas, effectively transforming the park into an active military base.
