The Atlanta Campaign began in May 1864 in a year which would see Douglas's Battery fight in 16 battles or skirmishes. During the campaign, the battery fought at Resaca, Peachtree Creek, and Ezra Church. The battery was assigned to Major A. R. Courtney's artillery battalion in John Bell Hood's corps. When Hood became the army commander, Stephen D. Lee assumed command of the corps. During the Battle of Atlanta on 22 July, Douglas's Battery was sent into action at 4:00 pm with Thomas C. Hindman's division. The cannoneers found it difficult to inflict damage on their enemies because the Union soldiers fought from entrenchments. However, the battery acquired four 12-pounder Napoleon cannons that were captured from the Federal army. Lieutenant Bingham noted that while the battery's original guns were worn out, the Napoleons were new guns. Douglas wrote, "I have much the finest battery I have ever had and perhaps the finest in our army".
