New York State Police Troop K recounts the story of the celebrated troop that served the people of New York from 1917 to 1950. With superb photographs, the book highlights events in the historic Hudson Valley area. Troop K, in its role as a cavalry unit, had direct connections to Theodore Roosevelt's Rough Riders and served special duty at West Point, during World War II, and after the death of Pres. Franklin Roosevelt. Originally the troop patrolled the state's southeastern corner from Albany out to the east end of Long Island. Today Troop K has 400 members and a territory covering Columbia, Dutchess, Putnam, and Westchester Counties.
