Let's see--in order:
1. Benedict Arnold. I know he was a good general; however, I think Washington accomplished far more (winning battles isn't everything) and Nathaniel Greene I also feel is better than Arnold. In the latest list, none are in the top 100 anyway. I'd rank them Greene, Washington, and then Arnold.
2. Patton is off the top 100 at this point. The problem with WWII American generals is that they all worked as a team and it is very difficult to distinguish who really could even be on this list.
3. Suvorov has been climbing, from 23rd originally up to 6 now. I find it difficult to rank him higher due to the lack of a marquee opponent.
4. Alexander has been at the top from the start; the way I see it, the top 4 are far above the rest. I would agree with you that Genghis is the only other real choice for 1, and I don't think his exploits really beat out Alexander. Though it is close.
5. Caesar. I am comfortable with him at #12.
6. Rommel. Rommel has an extraordinary number of people both bashing and supporting him. The way some tell it, any halfway decent general would have won in the desert... I'm holding him low due to the secondary theater nature of his conquests.
7. Constantine and Basil II. I never have enough info on some of the older generals. I didn't even put Basil on until this list...
8. David. He took a hill-country group of semi-autonomous tribes, welded them into a unified army and expanded to the Euphrates and the border of Egypt. The Bible mentions several flanking tactics... I consider the Bible more accurate than any other of the ancient documents on historical matters.
9. Sforza. Another new addition, and one with whom I am unfamiliar. I don't have enough info on what he did, having never studied the condotierro extensively.
10. Gustavus Adolphus. I consider him one of the greatest innovators, thus his high ranking. He started out at #4 on this list and has since dropped to #10. He made Sweden a superpower, which is saying something.
Thanks for the comments, guys! Keep them coming!
