nsville Pass, near which and over Elk Ridge a road passes through Solomon's Gap of Elk Ridge.
From the top of this gap is a rugged way along the ridge leading down to its southern projections and limits, by which infantry only could find foothold.
That southern point is called Maryland Heights. Two brigades-Kershaw's and Barksdale's — under General Kershaw were ordered to ascend Elk Ridge, march along its summit, driving off opposition, and capture the enemy's position on the heights.
General Semmes was left near the pass, over which the troops had marched with his own and Mahone's brigades, the latter under Colonel Parham with orders to send a brigade to the top of Solomon's Gap to cover Kershaw's rear.
General Wright, of Anderson's division, was ordered with his brigade and two pieces of artillery along the crest ridge of South Mountain to its projection over Riverton.
General Cobb was ordered with his brigade along the base of Elk Ridge, to be abreast of Kershaw's column.
