During the Battle of Atlanta on 22 July 1864, Bridges' Battery unlimbered north-northeast of Atlanta and began shelling the Confederate defenses at 3:00 pm. Starting at 6:00 pm on 23 July and continuing for 26 hours, the battery bombarded the Atlanta defenses. For 12 hours, one gun was fired every three minutes, while the firing interval was increased to every five minutes for the next 14 hours. The guns fired almost every day until 12 August when the battery moved to a new position. From then until 25 August, firing was occasional. On 2 August Sergeants Dodge and Lawrence were both promoted to second lieutenant. The unit participated in the flank march from 25–30 August, ending in the Battle of Jonesborough on 1 September. During the campaign, the battery sustained personnel losses of two killed, six wounded, and four captured. Captain Bridges submitted a report on 9 September 1864 in his capacity as IV Corps chief-of-artillery. He listed the armament of Bridges' Battery as five 3-inch Ordnance rifles and noted that the battery expended 130 solid shot, 1,815 percussion shell, 1,212 fuse shell, 2,092 case shot, and 14 canister shot in the campaign.
