Bald Hill was located a couple miles east of Atlanta. In an effort to slow the Federal advance on the city, Maj. Gen. Patrick Cleburne's Division and elements of Maj. Gen. Joseph Wheeler's Cavalry Corps defended this position on July 21, 1864, against Maj. Gen. Francis P. Blair's XVII Corps. The Confederates were entrenched on top of the hill facing east, the Federals attacking up the slope. Both sides fought to a standstill after a small but very fierce battle, Cleburne stating that it was "the bitterest fight" of his life. The fight produced over 1,000 casualties; Blair had lost around 700 men and Cleburne near 300.
The Confederates withdrew from the position that night, Cleburne's linking up with the rest of Lt. Gen. William J. Hardee's Corps and marching around the Federal Army of the Tennessee's left flank, culminating in the Battle of Atlanta the following day.
The hill was also a critical terrain feature in the Battle of Atlanta, July 22, situated at the Federal center and again fiercely contested by both sides. It would later be known as "Leggett's Hill," after Brig. Gen. Mortimer D. Leggett, who's division attacked the hill on July 21 and defended it on July 22.
Like the rest of the Atlanta battleground, today the hill is completely paved over. It was leveled during highway construction in the 1960s and is now the intersection of Moreland Avenue and I-20.
