“I have done the best I could for my country; to the last I have done my duty as I understand it.  That I must have made many mistakes I cannot deny.  I do not see any great blunders; but no one can judge of himself.  Our consolation must be that we have tried to do what was right.” – Major General George B. McClellan, upon being relieved of command of the Union Army of the Potomac, 1862
