The 1st Battalion, 112th Infantry Regiment draws its origins from Civil War era units, including the 13th, 15th, and 17th Pennsylvania Regiments and still maintains the right to possess the silver bands and battle streamers awarded for battle service in the Peninsula and Virginia 1861–1863 campaigns and for participation in the battles of Manassas, Antietam, Fredericksburg, Gettysburg, the Wilderness, and Spottsylvania. On 22 November 1878, the battalion was organized as the 16th Regiment, Pennsylvania National Guard. The regiment consisted of companies from Erie, McKean, Venango, Elk, Warren, and Crawford counties. The units were located in Erie (Co A), Bradford (Co C), Oil City (Co D), Cooperstown (Co E), Franklin (Co F), Ridgeway, Pennsylvania (Co H), Warren (Co I), and Titusville (Co K).
