The regiment engaged in numerous stiff fights during the Atlanta Campaign in the summer of 1864; it saw the elephant in the face of heavy fire at Resaca, was hurled against enemy fortifications at Dallas, and won and held enemy trenches at the point of the bayonet at Gilgal Church. The regiment began the campaign with 600 men, but by the time Sherman's army reached Atlanta three months later, its strength had been reduced to 175.
