Damn! You beat me to it! I was gonna mention Col. Joshua "The Fightin' Professor" Chamberlain coming out of Bowdoin. Funny that the trustees wouldn't give him a leave of absence to enlist, so he asked for a year off to study in Europe and they approved, of course.
He was there at Appomattox Courthouse at the end. Between he and General Gordon, and, of course Lee and Grant, they did a beautiful thing there. Imagine how horrible it might have been had someone other than those gentlemen been in charge. The healing began right there. Too bad so many want to keep picking the scab, even to this day. ":^/
