Ulysses S. Grant

If Ulysses S. Grant were a drink, he'd be straight whiskey—no chaser, just like his battlefield tactics. In the 'Greatest Presidents' league, he's the underdog with a beard, battling through scandals like a champ. And in the 'Greatest U.S. Generals' arena? The man's a legend who basically told the Civil War, 'You're gonna end on my terms!' Fans are split: some say he's a strategic genius, others just can't get past the fact that his horse probably had better public relations skills.
