Who is this person?

I don't know much about U.S. Grant, but I'm pretty sure that he is the one who said this during the Mexican war. The story that I heard was that the army was so slow in advancing on Monterey that even the pack animals got lazy, and Grant had to get them moving -- and did so routinely and with no angry outbursts. Same method works on most children...

I remember thinking at the time that it was hard to believe that a military man never used profanity.
