Interesting color-printed battle plan showing the operations of General G. W. Morgan in the Cumberland Gap, Tennessee. General Morgan's actions resulted in the capture of the Cumberland Gap for the Union. The Union occupied the Gap for three months.
The map names a number of important authorities as its sources:
- Bvt. Brig. Gen. O. M. Poe's Map of East Tennessee.
- Bvt. Brig. Gen. J. H. Simpson's Map of Kentucky and a portion of Tennessee.
- Col. W. E. Merrill's Map of Middle and a portion of East Tennessee.
- Maj. S. S. Lyon's Maps and Sketches of Cumberland Gap and vicinity.
