Good list Redguard. Think your the first to mention Caeser. As for Lenin, I'm unaware if he held any military rank, but he was a leader that vastly changed Russia forever. Could you give me/us some background on if he actively planned military operations? I'm pretty sure he did, just need some clarification.
OSTHEER IS DONE WHEN IT'S DONE!
Personally I wouldn't consider Lenin, Stalin or Hitler military leaders. If you include them you can include any US President since they're technically Commander-in-Chief or even the Queen.
Lenin and Stalin for debate I suppose. Hitler on the other hand was just a Corporal (heh) and should be ranked on the top of Worst Military Leaders of all time.
Ho Chi Minh (not because I'm a Vietnamese, yes I'm a Vietnamese, he made things from NOTHING dude!)
