July 22, 1864. Harrow´s 4th div. (composed of Walcutt´s, Oliver´s & Williams´ brigades), 15th A.C. [Union] occupied this sector between Leggett´s Hill & the Ga. R.R., which was the outer Confederate line until abandoned that morning.
When Coltart´s & Benton´s brigades of Brown´s div., Cheatham´s A.C. [Confed.] assaulted this sector, Oliver´s & Williams´ troops gave way under a like pressure that broke Morgan Smith´s line at the railroad, only to return at Harrow´s command & re-possess it in a resurgent wave that restored it & the broke section northward. This action is pictured in the Cyclorama of the Battle of Atlanta in Grant Park.
