I am not a big fan of history, particularly about battles and wars, but this book made it all easy and interesting, I am grateful to the author for his skills and his extensive research. The sacrifices of the soldiers under the amazing leadership of General Washington should make all of us humble, and remind us of the prices of maintaining liberty that we often forget and take for granted. Very important piece of American history, and also enjoyable.
