The Reb and the Redcoats by Constance Savery
This is one of the possible resources listed for RC History's Connecting with History Volume 4A (American History).
A captured American soldier-colonist, the Reb, is held at a private residence in England. The action of the Revolutionary War is far away, but the book shows some of the effects on those who return from war or have friends and family in harm's way. It's a book about honor, chivalry, friendship, and seeing the humanity of those who are our political enemies.
It would be appropriate for reading aloud to the whole family and I think I'd like it a lot better than reading Mr. Revere and I, which I'll have as an option for First Son (sixth grade) or First Daughter (third grade) to read independently.
The links above are affiliate links at RC History. I purchased this book directly from the publisher, Bethlehem Books, during one of their many great sales. (I actually purchased the Kindle version from the publisher a year ago, but we didn't get to this unit last year and I took advantage of a sale to get a real book for the kids to read.)
