The Hobart Gap is a pass and road through the Watchung Mountains in Northern New Jersey. During the American Revolutionary War, Hessian General Baron Wilhelm von Knyphausen attempted to seize the Hobart Gap, now crossed by present-day Route 24, in order to attack the American headquarters in Morristown for the British. He was met with successful resistance by General Nathanael Greene, and was eventually defeated by the Continental Army and the New Jersey Militia at the Battle of Springfield.
