THE BUCKTAILS AT THE DEVIL'S DEN, the sixth novel in the Bucktails Civil War series, returns the battered regiment to the defenses of Washington. Instead of the soft duty they envisioned there, the riflemen are harassed continually by Rebel guerrillas and the Gray Ghost, John Mosby. The action intensifies when the First Rifles are ordered on the double-quick march to catch Lee's invading Rebel Army at Gettysburg. The Bucktails' brutal counterattack from Little Round Top and their bloody skirmish at the Devil's Den add another heroic chapter to the illustrious history of the 42nd PA Volunteers.
