I ahve to gow with Stonewall Jackson. As a motivator and tactician he accomplished so much with so little. He gave the army of Northern Virginia the offensive lena that carried them from 1862-1863. i am a big Lee fan as well, but I don't think he was flawed as an offensive general - he needed to keep that Army together and in that he failed.
Patton is on the list as well - as is McArthur. I am a big admirer of Vinegar jor stillwell and i think Pershing is underrated.
Crazy Horse is there is you exapnd the defintion and David Pertaeus amy be re-defining American military doctrien for teh new century.
I'm tired of reading about Nazis - who do you think ranks at the head of the class for American mlitary leaders?
