Two of McClellan's many triumphs are being celebrated by the USPS, which is exceedingly careful not to mention his name. They have studied their pop history well.
p.s. I should publish Adm. Porter's personal letter to McClellan (see the McClellan Papers originals) asking McClellan to credit him with the idea for the New Orleans expedition. The record on this is most interesting and absent from Civil War histories.
