Fort Gibson Defending the Approaches - Jersey City, NJ - Signs of History on Waymarking.com

The plaque says, "The fort that stood here on Ellis Island was part of two defensive triangles which made it almost impossible of enemy ships to approach New York City. Any ship entering the upper harbor first had to pass the guns of Fort Wood on Liberty Island and then pass though the crossfire from Fort Gibson on the west and from Castle Williams on Governor's Island to the east. In the unlikely event that a ship was able to slip through this gauntlet, it would then face an even greater challenge - passing though the second triangle, formed by Ellis Island, Governors Island and the Battery of lower Manhattan. Within this second triangle, the farthest a ship could be at any time from the guns of one of these harbor defenses would be 1,000 years. No enemy ever tried to penetrate this extraordinary defense system."
