The Thirteenth Pennsylvania Reserve Regiment, also known as the 42nd Pennsylvania Volunteer Infantry, the 1st Pennsylvania Rifles, Kane's Rifles, or simply the "Bucktails," was a volunteer infantry regiment that served in the Union Army during the American Civil War. It was a part of the famed Pennsylvania Reserve division in the Army of the Potomac for much of the early and middle parts of the war, and served in the Eastern Theater in a number of important battles, including Antietam, Fredericksburg, and Gettysburg.
The "Rifles" designation was a holdover from the days when soldiers who carried rifled weapons wore a special outfit, and the Bucktails carried breech-loading Model 1859 Sharps Rifles, normally only issued to sharpshooters.
