I've decided to start up a project of my own and I've wondered, what can you tell me about the historical characters America interacted with during the Revolution? Preferably George Washington. Do you know where I can look for strips or more information?
As far as Hetalia goes, there are no specific historical figures that America is shown interacting with during the American Revolution. Washington was only mentioned once in text after a strip: http://www.hetarchive.net/scanlations/xmas2011/kur.php
This page has a strip with a character some have theorized to be Washington, but there's no information confirming whether it is or not: http://www.hetarchive.net/scanlations/xmas2011/2011_12_6.php
That's all I can offer.
