Illinois Civil War Regiments

Illinois Civil War Regiments

The state of Illinois during the American Civil War was a major source of troops for the Union army (particularly for those armies serving in the Western Theater of the Civil War), and of military supplies, food, and clothing. Situated near major rivers and railroads, Illinois became a major jumping off place early in the war for Ulysses S. Grant's efforts to seize control of the Mississippi and Tennessee rivers.

Illinois contributed 250,000 soldiers to the Union Army, ranking it fourth in terms of the total manpower in Federal military service. Illinois troops predominantly fought in the Western Theater, although a few regiments played important roles in the East, particularly in the Army of the Potomac. Several thousand Illinoisians were killed or died of their wounds during the war, and a number of national cemeteries were established in Illinois to bury their remains.

Besides President Abraham Lincoln, a number of other Illinois men became prominent in the army or in national politics, including Ulysses S. Grant (a resident when the war started), John M. Schofield and John A. Logan. No major battles were fought in the state, although several river towns became sites for important supply depots and "brownwater" navy yards. Several prisoner of war camps and prisons dotted the state, processing thousands of captive Confederate soldiers.
