Rome\'s most able general?

[Sean Manning]

....let us not forget that we only have our sources to guide us, and some certainly exaggerated the virtues of certain generals......others blew their own propaganda trumpets ! (J. Caesar springs to mind).
Perhaps Rome's most able general was one of those who have not had their story told by the ancient historians.....

Its not Roman, but look at the Persian civil war in which Darius the Great took over the empire. Nineteen battles in a bit over a year, and all we know is roughly when and where they occurred and who won (and even that is from royal propaganda).
