The second battle, on June 25, 1832, is described as the last Indian battle or skirmish on Illinois soil. The graves of soldiers killed in the war's local fighting lie at the monument.","narrative":"Kellogg's Grove is a Black Hawk War battlefield southeast of Kent, Illinois, set on a knoll overlooking the Yellow Creek and Plum River valleys. Oliver W. Kellogg settled here in 1827, building a log cabin and barn on the trail between Peoria and Galena; the cabin often served as an inn for travelers. In June 1832 two battles were fought at the site. In the first, soldiers under Captain Snyder lost three men. In the second, on June 25, Major Dement's militia fought a force led by Black Hawk, and several soldiers were killed. That fight is described as the last Indian battle or skirmish on Illinois soil. Today a small county park holds a limestone monument raised in 1887, topped with cannonballs and enclosed by an iron fence. Soldiers killed in the area are buried at its foot. The cabin foundation and wagon ruts survive on adjoining farmland, and the nominated area covers 56 acres.","period_of_significance":"1827, 1832 and 1887 (specific dates given)","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"A county park of about one-half acre holds the monument, playground equipment, a shelter house and rest rooms.
