New Jersey welcomes the world to Rockingham State Historic Site this summer for the 250th Birthday of the United States. Rockingham was George Washington's final wartime headquarters. Arriving from New York, Washington stayed at Rockingham from August 23, 1783 and left November 10, 1783. While at Rockingham, Washington entertained guests, issued his Farewell Orders to the Army, and learned the United States became formally independent with the signing of the Treaty of Paris.

THIS EVENT TAKES PLACE AT HILLSBOROUGH LIBRARY, 379 S. BRANCH ROAD, HILLSBOROUGH TOWNSHIP NJ 08844. Author, Arthur S. Lefkowitz will talk about his book: "George Washington's Indispensable Men: Alexander Hamilton, Tench Tilghman, and the Aides-de-Camp Who Helped Win American Independence." While history has immortalized George Washington, it has largely forgotten those who helped to propel him to greatness—the thirty-two men who served as his aides-de-camp during the Revolutionary War. Washington relied heavily on these men—among them a young Alexander Hamilton—for help in formulating policy and strategy. "George Washington’s Indispensable Men" details the fascinating and sometimes tragic lives of these aides, providing a new and refreshing look at the American Revolution. Presenter: Arthur S. Lefkowitz is known for tackling offbeat but interesting subjects that present a research challenge. All of his books deal with some aspect of the American Revolution and his unique subjects include the story of the American Turtle submarine; the 1775 Arnold Expedition; the wartime exploits of Aaron Burr and George Washington's Revolutionary War aides-de-camp. His latest book is titled "George Washington's Revenge".
