@ Jetsfan - great historical comparison. Yes, Scipio beat Hannibal at Zama, but Hannibal and his army were hardly at their zenith. And Hannibal, of course, goes down in history as the great general, while Scipio is nearly unheard of outside nerd circles. Yet in defense of Scipio, he managed to conquer Spain while Hannibal floundered in Italy. Hannibal was the brilliant tactician; Scipio knew how to win wars. An excellent comparison indeed.
Now, concerning Chancellorsville - I will concede the point there, that was a truly brilliant battle, Lee's finest, and I don't think Grant has a single set-piece battle to match it. My argument is that Grant's Vicksburg *campaign* was a series of tactical successes that led to a crushing strategic victory, and that Lee has no comparable campaing. And while Grant had even numbers in that campaign, the terrain heavily favored the defender. But Grant had the supreme respect of his fighting men, every bit as much respect as Lee commanded in his army. However, Grant never got the post-war love that Lee got, probably, as noted by someone else above, because of a combination of his alcoholism and his utter incompetence as a president.
Grant is a sort of tragic figure to me. He seems to have failed at everything in his life - at least in his public life and career - except a few years as a wartime officer. He was the man of the hour, the general who saved the Union, but history has passed him over in favor of Lee. Scipio is indeed an apt comparison, and I would add Wellington to the list. Which leads us to a new thread......
