I also heard that US Grant got lost when he was trying to find Vicksburg. He ended up in a whorehouse in New Orleans and wasn't heard from for 12 days.
Fortunately, there wasn't any Internet then, so they were able to cover it up.
Oh, yeah, and where is he now? He liked Louisiana so much that, after retiring from politics, he moved to the Gulf Coast, and runs a fishing boat with his good friend, Bob Dylan, right outside of Delacroix.
