This is a great in-depth look at how George Washington and American troops emerged victorious and gained independence in the American revolution. 1776 (2005) looks at both sides of the war, both English and American, through journals, diaries, articles, and other war documents to paint a vivid picture of what happened.
David McCullough even puts in clarifications to some of the facts that were written by soldiers at the time so they more accurately reflect what happened in battles. The writing is very accessible and easy to follow compared to some historical books that are bogged down by dated language. If you are a fan of history, this is a great book to look at for more information on the American revolution.
