Pinned to a town

Civil War regiments were raised locally: each was recruited from the eligible men of one or more nearby counties, organized at a rendezvous camp, and sent to the front. In Illinois, 33 of the 196 regiments below are pinned to the specific town where they formed; the rest are recorded honestly at the state level. The largest single unit raised in Illinois was the 1 Illinois L. Art'y., with 5,660 men in the records.

To search these regiments by a family surname and read the individual men who served, with their rank, company, and side, explore any location in Illinois.
