Fort McCoy is a United States Army installation on between Sparta and Tomah, Wisconsin, in Monroe County. In 1909, there were two separate camps named Camp Emory Upton and Camp Robinson; in 1926, these camps were joined together to form Camp McCoy. Since its creation in 1909, the post has been used primarily as a military training center. A part of Fort McCoy is also used by the Wisconsin State Patrol as a training facility. History The post has been in virtually constant use since it was first formed as the "Sparta Maneuver Tract" on 14,000 acres (57 km2) in 1909. At first, the tract was made up of two camps, Camp Emory Upton and Camp Robinson. These were separated by a line of the Chicago, Milwaukee, St. Paul and Pacific Railroad that ran across the land from east to west. In 1910, the army renamed the entire tract "Camp Bruce Elisha McCoy" for the father (a Civil War captain) of Robert Bruce McCoy, a retired major general who first proposed the area as a training ground and bought part of the property on which the fort stands. In 1926, the name of the post was officially renamed "Camp McCoy" in honor of Robert Bruce McCoy, who had died in January of that year. It has gone by many different names such as Sparta Maneuver Tract; Sparta Military Reservation; Camp McCoy; and now the present, Fort McCoy. The name McCoy comes from Robert B. McCoy who was a military man, farmer and served as county judge who initially set up the land as a military camp. In 1938, the United States began a major expansion of the camp. This included the addition of over 45,000 acres (180 km2) to the post, as well as the construction of several new structures, including living quarters for the troops. This increased the camp's capacity to 35,000 soldiers. In all, the project was estimated to have cost about $30 million. The expansion was officially concluded with a new inauguration on August 30, 1942. During World War II, Fort McCoy was used as a concentration camp for approximately 170 Japanese and 120 German and Italian American civilians arrested as potentially dangerous "enemy aliens" in 1942. After the internees were transferred to other camps, McCoy was used as a training facility for units from across the country preparing to enter combat, including the segregated all-Nisei 100th
