 Sherman erred when he assumed that all of Johnston's army had marched from Adairsville, as Hardee had, to Kingston.This resulted in his ordering his forces concentrated here—discovering later that the Confederates were east at Cassville and not at the Etowah River south of Kingston.On May 19 Union generals Daniel Butterfield and Joseph Hooker, the new XX Corps, were headquartered at the house of Confederate Colonel Hawkins F. Price, a state senator who had voted for Georgia secession in 1861.
