You can sum up his generalship as this: From start to finish, he never lost a battle.
And he never stopped coming after you. That was his true strength. In a couple of battles, he was close to even with his opponent (I think but am not sure it was that way at Doneldson and at Cold Harbor, he had a numerical superiority but not by much). He just took the initative and kept going.
In truth, he was a scary little guy to have after you. He never stopped, he never gave up and he would try just about anything.
But, in a different line of thought. Anybody have any idea what a battle between Lee and Sherman would've looked like? Not the early Sherman, and not the late Lee. But when both were in their prime (Sherman in 1864 and Lee in the Spring of 1863). Lee has the services of Jackson and Longstreet. Sherman has Sheridan and Thomas.
Any thoughts?
