The First Kentucky Brigade became part of the Atlanta Campaign on May 7, 1864, when they left their winter camps and took up positions on Rocky Face Ridge. The regiment became part of the fighting retreating force as Maj. Gen. William T. Sherman pushed the Confederates further back toward Atlanta. At the Battle of Dallas near New Hope Church, the First Kentucky Brigade made an unsupported charge, losing 51% of its strength. At the Battle of Jonesboro on August 31, 1864, the brigade was ordered to attack the entrenched federal position. At an unseen deep ravine, the attack came to a halt. The following day, the Confederates were overwhelmed when two-thirds of a Union Army division attacked and began to surround their positions. Many of the men of the 2nd Kentucky Infantry, 6th Kentucky Infantry, and 9th Kentucky Infantry were captured. The remnants of the brigade fell back and managed a successful defense against the Union assault, bringing it to a halt. On September 4, only 500 men were present for duty in the entire First Kentucky Brigade.
