During the Civil War, military units, including the Fifth Tennessee Infantry Regiment, organized on the courthouse lawn. Henry County sent more than 2,500 volunteers to the Confederacy and earned the title “Volunteer County of the Volunteer State.” In March 1862 General Ulysses S. Grant ordered four companies and a battery of artillery into Paris. The Union forces attacked an encampment of 400 Confederate soldiers but retreated toward Paris Landing after a short engagement. In October 1864 General Nathan Bedford Forrest began his Johnsonville campaign at Paris Landing, where he captured four Union gunboats, fourteen transports, twenty barges, twenty-six pieces of artillery, $6,700,000 worth of property, and 150 prisoners.
