Well document history of Sherman's cavalry during the Atlanta campaign. The author used regimental histories of the cavalry and artillery units assigned to the cavalry. It breaks the myths that the cavalry were ineffective during the campaign and deals with the failures of its superior officers ie. Stoneman, McCook and Kilpatrick. While at the same time it enlightens us to how affective Rousseau was on his little known cavalry excersion through Alabama and west Georgis. It also explains why Sherman who never had cavalry experience expected too much from his cavalry and when they failed he never assigned them a primary role even through his March to the Sea. It also explains why Sherman choose Kilpatrick as his head of cavalry on his march to the sea and refused James H. Wilson's talents which set the stage for Thomas to benefit of Wilson's skills at the Battle of Nashville. This history also gave evidence why Thomas was more affective on using Stoneman, McCook's talents in a more controlled area during the fall and winter of 1864. ( )
