Bumped.
As I mentioned in another thread, when I first started reading about Sheridan when I was a boy, I was generally given the impression that Sheridan was a great general, part of a "triumvirate" along with Grant and Sherman that won the war for the North. As I have delved more deeply into the campaigns of 1864, this idea has fallen apart. As the commander of the cavalry of the Army of the Potomac, he basically dropped the ball completely when it came to scouting and reconnaissance and completely botched clearing the roads for the advance from the Wilderness to Spotsylvania. He won the Battle of Yellow Tavern, with odds of three-to-one in his favor, but he certainly can't claim personal credit for the killing of Jeb Stuart (which belongs to Private Huff). And his raid really didn't accomplish much of any importance. Later on, Wade Hampton and Fitzhugh Lee trounced him at Trevilian Station.
As commander of the Union forces in the Shenandoah Valley, Sheridan had about 40,000 men against Early's 15,000. Yet he still nearly botched the Third Battle of Winchester through the simple mistake of funneling most of his army through a single defile. He failed to pursue Early after both Third Winchester and Fisher's Hill. He underestimated Early so much that his army was surprised and nearly routed at Cedar Creek.
I give Sheridan high marks for his ability to inspire men in the field, but I can't really consider him that good a general.
