Apparently, the Pilgrims did more than wear buckle shoes and funny hats and forge friendships with Native Americans. Who were they, exactly, and how pure were they? In her new book, The Wordy Shipmates, author Sarah Vowell, funny-voiced contributor to National Public Radios This American Life and author of Take the Cannoli, investigates. She discovers that -- surprise! -- while Americas founders were, indeed, deeply principled, they were also quite feisty and often vengeful and violent.
