During demonstrations on Rocky Face and in Crow Valley by 4th and 23d Army Corps troops, the northern line of Dalton’s defense works crossed the road here. Stevenson’s division of Hood’s Army Corps held this sector, with its left at Cheatham’s line at Signal Station on Rocky Face and its right at Ault’s Creek, east, on May 9, 1864. Stevenson’s men repulsed the 23d Army Corps in Crow Valley and also turned back the desperate attempt by Harker's and Wagner's brigades of Newton’s division, 4th Army Corps, to break Stevenson’s left at and near the top of Rocky Face, where Pettus’ and Brown’s brigades were posted behind stone breastworks that are still there.
