The Battery sits at the tip of Manhattan and over the course of four centuries it has served as a fort, a haven for newly arriving immigrants and a refuge from city life for harried New Yorkers. On September 11th 2001 it would become the focal point for a maritime evacuation that rivaled the British efforts at Dunkirk in 1940. During the course of that day, an obscure homicide would later compel an NYPD detective to find the murderer of his partner in New York subway tunnel. The result of this investigation would shock many and would illuminate a root cause of the 911 terrorist attack on the World Trade Center Towers.
