Turtle Submarine Attempts First Naval Attack

As the American Revolutionary War intensified around New York, inventor David Bushnell developed the Turtle, a one-man wooden submersible designed to attach explosive charges to British ships. On September 7, 1776, Sergeant Ezra Lee piloted the craft into New York Harbor under cover of night, targeting Admiral Richard Howe's flagship HMS Eagle. Lee maneuvered beneath the vessel but struggled to drill through its copper-sheathed hull due to the tool's limitations and strong currents. The attempt failed when the bomb detached prematurely and exploded harmlessly nearby, alerting the British without damaging their ship. Though unsuccessful, the mission marked the first combat use of a submarine in naval warfare.
