During the Atlanta Campaign, Hood urged the normally cautious Johnston to act aggressively, but Johnston usually reacted to flanking maneuvers by Sherman with timely withdrawals, rather similar to his strategy in the Peninsula Campaign. One attempt by Johnston to act decisively in the offensive, during the Battle of Cassville, ironically was foiled by Hood, who had been ordered to attack the flank of one column of Sherman's army, but instead pulled back and entrenched when confronted by the unexpected arrival of a small detachment of that column.
