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.
For thousands of years the pass in the mountain range was an important aspect of the traditional Lenape Minisink Trail.
From the pass, the trail led to a landing at the best place to ford what the Native Americans called the Fishawack (the Passaic River).
Route 24 was recently redirected around the old road in order to retain the historical downtowns of the colonial villages through which the trail led.
