Illinois sent 239 regiments and batteries into the Union army during the Civil War, but almost all of them served in the western theater. Only a little over one thousand men from Illinois fought at Gettysburg. About 140 (14%) became casualties. (See the States at Gettysburg) There are three Illinois monuments on the Gettysburg battlefield, honoring the one Illinois infantry regiment and portions of two cavalry regiments that fought here.
