The mission of Camp Mills was initially the preparation of Army units prior to their deployment to Europe in
World War I. It was established as temporary tent camp in September 1917 as a place to mobilize the
42nd Division, made up of
National Guard units from various states. After the 42d left for the
Western Front in
France, the
41st Division followed, occupying the camp from October to November 1917. The camp was then ordered to be abandoned, but reestablished April 4, 1918, as a part of the New York Port of Embarkation at
Hoboken,
New Jersey to obtain additional facilities for troops in transit to Europe. Camp Mills was expanded to a cantonment with wooden buildings for the accommodation of thousands of troops, who arrived from training camps across the United States. The units waited until they could be scheduled for embarkation whereupon they would travel by trains of the
Long Island Rail Road (LIRR) to board ferryboats for the overseas piers in Brooklyn or Hoboken and loaded onto troop ships. Those ships transported troops primarily to the ports of Liverpool, England, or Brest, France. Facilities at Camp Mills included a hospital, warehouses, bakery, delousing plant and other facilities. It eventually consisted of about 1,200 buildings with a capacity of 46,000, including space for 40,000 transients (about half in barracks, half in tents), a 500 inmate detention camp and 5,500 members of a permanent garrison. A very large number of American soldiers shipped out to France from Camp Mills, at its peak in September 1918, over 31,000 troops were stationed there. Notable individuals who were assigned during World War I were:
Douglas MacArthur,
Wild Bill Donovan,
Joyce Kilmer and
Father Duffy among them.
F. Scott Fitzgerald was a soldier at Camp Mills. With the end of World War I in November 1918, Camp Mills served as a demobilization center processing thousands of troops back into the United States. When the last returned during the summer of 1919 the camp was ordered to be abandoned and sold, although operations continued until garrison troops were transferred elsewhere on March 31, 1920. In 1938 Camp Mills was incorporated into
Mitchel Field as part of an Air Corps expansion. ==Aviation Concentration Center==
