In additional to collecting pre-1920 Red Sox and RI Breweriana, I am a pretty involved student of the American Revolution and have been for over thirty years. I happened to run across the episodes of this series that dealt with the Revolution and all I can say is that this is the most horrendous documentary I have ever seen on the subject (I was actually involved in the filming of the original History Channel documentary on the Revolution back about 15 years ago). Most documentaries fall short of being perfect in this period, but this show was blatantly WRONG most of the time. The History Channel should be ashamed of itself for putting out such a piece of trash. I know that may sound harsh, but if a program was completely wrong about baseball, you would all feel the same way. This "documentary" obviously never consulted appropriate historians and relied on talking heads that know nothing of the subject.
I can't comment on any of the other episodes as I did not watch them. I do know that some friends who are students of the Civil War did not have many promising things to say about that episode. Sorry to bust anyone's bubble who thought this was a good series. It was simply terrible. You should see the comments on similar forums like this that deal with history. Unfortunately, the History Channel has gone away from history. They're more involved in putting things out like Ice Truckers, Pawn Stars, and the like which have little to do with history.
Seeing that the original intent was to see pieces of "Americana" here's one from the Revolution. A Proclamation printed in RI for the distribution throughout the state announcing the Cessation of Arms between the United States and Great Britain. Probably the only one known to exist.
