Camp Grant, IL.
Version World War 1.0
CG was one of 16 National Army cantonments that would train young men for first world war out of eleven. It was located 4 miles south of Rockford, in Winnebago County, and named in honor of Gen. Ulysses S. Grant, U. S. A.,Commander-in-Chief, U. S. A., 1864-69, and President of the United States, 1869-77.
This camp was first established on July 18, 1917, to serve as training camp for 86th Div. (National Army), which occupied the cantonment. August 1917-August 1918.
The construction started here on June 24, 1917, and continued through 1918. The first draftees reported for duty on September 1-15, 1917, while the last, December 1-15, 1918.
CG was classified as infantry replacement and training camp, April 1918 and as a demobilization center, December 3, 1918. After Armistice it was retained as permanent reservation. That was typical for N.A. cantonments as opposed to National Guard camps; many of which never saw any action for the second world war out of eleven.
While Camp Grant was retained, a lot of the buildings were razed after the Great War; only for the place to be totally rebuilt for WWII, and torn down again. (Your taxdollars at work.)
Also, during WWII, Camp Grant served a much smaller role, and was not even in the top 50 of training camps in terms of size. Quite a contrast from WWI, where it was one of the largest facilities!
During the first world war, there was a cantonment of 1,515 buildings with a troop capacity of 42,819, enough to rival the nearby town of Rockford.
In 1919 $, the construction costs were about $14,000,000. In 2026 $ that would be worth $267,224,393.
In contrast, much less was spent during WWII to rebuild it. In 1945 $, it cost Uncle Sam $10,003,656. In 2026 $ that would be worth $183,518,737, or about 2/3 the cost of WWI.
The size of the cantonment site proper was 1600 acres; entire reservation, 5,665 acres; including shooting ranges. But, during WWII it was only 3,338 acres.
Many of the former National Army cantonment sites saw plenty of post WWII use; some of which are still active today, and have advanced in rank to achieve permanent fort status. But, there was no Fort Grant or Fort Ellis. As a matter of fact, other than Fort Sheridan, there were not any post WWII forts in Illinois. Finally, FS was on the list for the very first BRAC round of 1988, and closed in the 1990s.
Today the former site for Camp Grant is the airport for Rockford. That's ironic, because its usually growing cities infested with NIMBYs that gobble up airports, and make them disappear. In fact, Camp Grant would have been large enough to be in the top five Illinois cities at the time. But instead, an airport displaced this former Army city.
However, there was an occasional plane that few in and out of the parade grounds; well before any runways were ever added. But, there were no aero squadrons attached here, so the flights would have been inconsistent, and not a regular thing.
While there are no surviving WWI buildings, a few WWII buildings do remain east of the airport. As of yet, it is unknown if Camp Grant will be used for World War Eleven, or where the buildings will be located.
