The Battle of Resaca, from May 13 to 15, 1864, formed part of the Atlanta Campaign during the American Civil War, when a Union force under William Tecumseh Sherman engaged the Confederate Army of Tennessee led by Joseph E. Johnston. The battle was fought in Gordon and Whitfield Counties, Georgia, and is generally viewed as inconclusive.

Joseph Eggleston Johnston was an American career army officer, serving with distinction in the United States Army during the Mexican–American War (1846–1848) and the Seminole Wars. After Virginia declared secession from the United States, he entered the Confederate States Army as one of its most senior general officers. From 1888 to 1889 he was a vice president, from 1889 to 1890 president, of the Aztec Club of 1847.
