Eric Herschthal, a staff writer for The Jewish Week, is currently researching a book on the early American republic. His writings have appeared in The New Republic, The New York Observer, and elsewhere.It’s hard not to feel bad for the Founding Fathers these days. After all, it is the Civil War’s moment. This year marks the 150th anniversary of the beginning of that ghastly war, and for the next five years it will get the lion’s share of attention. The challenge facing any historian writing a popular history of the Founders today, then, is to show that what they fought for—freedom, and independence—were not simple canards; that when the Founders wrote in the Declaration of Independence “all Men are created equal, that they are endowed by their Creator with certain unalienable Rights,” they actually meant it.That is the challenge facing John Ferling, a respected historian of the American Revolution, in his new book, “Independence: The Struggle to Set America Free.” To tell his story, he seizes on an underappreciated but profoundly significant moment in the eight-year War of Independence—the decision to not merely compel the British to reverse a series of onerous acts, but to break away from the empire entirely, and declare themselves a free and independent nation.
