After two years of defeats and reverses, 1778 had been a year of success for George Washington and the Continental Army. France had entered the war as the ally of the United States, the British had evacuated Philadelphia, and the redcoats had been fought to a standstill at the Battle of Monmouth. While the combined French-American effort to capture Newport was unsuccessful, it led to intelligence from British-held New York that indicated a massive troop movement was imminent. British officers were selling their horses and laying in supplies for their men. Scores of empty naval transports were arriving in the city. British commissioners from London were offering peace, granting a redress of every grievance expressed in 1775. Spies repeatedly reported conversations of officers talking of leaving. To George Washington and many others, it appeared the British would evacuate New York City, and the Revolutionary War might be nearing a successful conclusion. Then, on September 23, 1778, 6,000 British troops erupted into neighboring Bergen County, New Jersey, followed the next day by 3,000 others surging northward into Westchester County, New York. Washington now faced a British Army stronger than Burgoyne's at Saratoga the previous year. What, in the face of all intelligence to the contrary, had changed with the British?

Grand Forage 1778: The Battleground Around New York City by historian Todd W. Braisted explores the battles, skirmishes, and maneuvers that left George Washington and Sir Henry Clinton playing a deadly game of chess in the lower Hudson Valley as a prelude to the British invasion of the Southern colonies.
