In March 1862 Brig. Gen. George W. Morgan sent a brigade under Brig. Gen. Samuel P. Carter against the eastern end of the Confederate defenses at the Cumberland Gap. These defenses were now held by Col. James Edward Rains after Zollicoffer's defeat and death at Mill Springs. The Confederate works were considered too formidable to be taken by direct assault and Carter's force lacked sufficient artillery to match the well placed Confederate batteries.
