The multi-faceted Revolutionary War career of Benjamin Tallmadge included operations as a dragoon commander, intelligence and counter-intelligence officer, and master of combined land-sea operations. Tallmadge fought in the battles of Long Island, White Plains, and Germantown, and defended the Patriot population in the no-man's-land of Westchester County against British and Tory raiders. After Washington rewarded him with his own legion, he unleashed bold raids on British-occupied Long Island from his bases in Connecticut. All the while, he ran Washington's most active espionage ring in New York and Long Island. Reversing roles, he played a key role in foiling Benedict Arnold's plot to betray the American stronghold of West Point to the British. Tallmadge's Revolutionary service graphically illuminates the struggle in the region that witnessed the most continuous, relentless, often pitiless, fighting of the struggle. In particular, this book describes the internecine quality of the fighting in politically-divided Long Island and Westchester, and details how the struggle continued without let-up even after Yorktown. Though Tallmadge's fascinating post-war career receives careful attention, the book focuses on his Revolutionary War service.

In 1778, two years after the British forced the Continental Army out of New York City, George Washington and his subordinates organized a secret spy network to gather intelligence in Manhattan and Long Island. Known today as the "Culper Spy Ring," Patriots like Abraham Woodhull and Robert Townsend risked their lives to report on British military operations in the region. Vital reports clandestinely traveled from New York City across the East River to Setauket and were rowed on whaleboats across the Long Island Sound to the Connecticut shore. Using ciphers, codes and invisible ink, the spy ring exposed British plans to attack French forces at Newport and a plot to counterfeit American currency. Author Bill Bleyer corrects the record, examines the impact of George Washington's Long Island spy ring and identifies Revolutionary War sites that remain today.
