On the morning of Nov. 23, 1864, the main body of the 20th Corps of the Union Army, commanded by Gen. A.S. Williams, reached Milledgeville from Eatontaon. The Corps marched down Jackson Street to this point where companies were formed into line. With bands playing, the Corps marched by the Capitol Square and camped on the east side of the Oconee River. General Henry W. Slocum, commander of the left wing, occupied the Milledgeville Hotel which stood four blocks east of this point.
