On May 8, 1864, Maj. Gen. J.W. Geary, with Buschbeck's and Candy's brigades of the 2d division, 20th A.C., moved from near Gordon's Springs and reached the Babb Settlement at 3 p.m. McGill's Pennsylvania Battery, with 3 inch Rodman guns, was planted near Joel Babb's house and shelled the Confederate position at Dug Gap in Rocky Face Ridge. This was followed by a concerted assault up the steep scarp, with Buschbeck's brigade on the right and Candy's on the left. Repeated Federal attempts to seize the gap failed, but under cover of this engagement, McPherson's troops occupied Snake Creek Gap, 6 miles southwest.
