I do find it a bit odd that there’s a statue of Confederate General Lee at Antietam and not one for Union General McClellan, and it was General McClellan who won the Battle of Antietam.
So erect one of McClellan.
Perhaps he doesn’t have a statue because he didn’t get along with Lincoln.
McClelland didn’t ‘win’ so much as he ‘failed to lose’. Antiedam was an opportunity to crush the ANV on the wrong side of the Potomac River. Instead McClelland had to settle for a very narrow strategic victory — he did deny Lee’s vision of a victory on “Union Soil”. But only just. The ANV got away.
Had McClelland actually exercised command on his various corps commanders and made a coordinated assault something in Lee’s army would have broken. Most likely at the stone bridge where his lines were thin.
