Hazleton is a town in Luzerne County, Pennsylvania, United States. The population was 25,340 at the 2010 census, an increase of 8.6% from the 2000 census. During the height of the American Revolution in the summer of 1780, British sympathizers, known as Tories, concentrated from New York's Mohawk Valley, began attacking patriot outposts located along the Susquehanna River Valley in Northeast Pennsylvania. Because of the reports of Tory activity in the region, Captain Daniel Klader and a platoon of 41 men from Northampton County were sent to investigate. They traveled north from the Lehigh Valley along a path known as "Warrior's Trail," which is present-day State Route 93, since this route connects the Lehigh River in Jim Thorpe (formerly known as Mauch Chunk) to the Susquehanna River in Berwick.
