The problem with the "total defeat" issue is that it just didn't happen in the 1860s, unless the army defeated was locked up in a fortified position... two armies on foot means those retreating can always move faster than those advancing.
Grant's "total victories," for example, were against Buckner at Donelson and Pemberton at Vicksburg; it is only late in the war that the US had the overwhelming force to destroy rebel armies in the field, whether Lee at Appomattox or Hood at Franklin.
