U. S. Grant: Pipe Smoker?

"The cigar was an example of the change that stemmed from fame. Learning that he had kept one clamped in his teeth that critical afternoon at Donelson, whenever he was not using it like a marshal’s baton to point the direction for attack, readers had sent him boxes of them to express their admiration, and since Grant had never been one to waste things, least of all good tobacco, the long-stemmed meerschaum that had given him so much satisfaction in the past was put away while he concentrated on smoking up those crates of gift cigars."
