What the horses of your army have done...

Randy takes a look at Lincoln's wisecrack and answers the question - in detail - about what McClellan's horses had done.

I would add just one point: McClellan failed to embark most of his cavalry for the Peninsula - the formations not embarked when the "hold order" was issued fell to McDowell. Organized by Pope for his campaign, they were then ruined by the time McClellan got them back for the Maryland campaign. Let that set the stage for what Randy presents.
