Chickamauga is a city in Walker County, Georgia, United States. The population was 2,917 at the 2020 census. It is part of the Chattanooga, TN–GA Metropolitan Statistical Area. History Before the 1800s, the Chickamauga Cherokee settled around Chickamauga Creek, where they farmed and hunted the lands. They stayed there until their forced exodus during the Trail of Tears (1838). In the early to mid-19th century, the present town of Chickamauga was a large plantation in the rolling hills of northern Georgia. When the Cherokee Nation was divided into districts and courts in 1820, Crawfish Springs was made the capital of the new Chickamauga District. After the Cherokee removal, the first court in Walker County was held there in the former Cherokee courthouse. The local post office was Crawfish Springs. During the War of 1812, 500 Cherokee warriors from the area fought alongside General Andrew Jackson at the Battle of Horseshoe Bend, against the Creek Indians, who were aligned with the United Kingdom of Great Britain and Ireland. The battle ended in a victory for the Americans. The Lee and Gordon families greatly influenced Chickamauga's post-Cherokee history. In 1836 Gwinnett County native James Gordon established a plantation at Crawfish Springs and built a grist mill two miles east of town, on Chickamauga Creek. Lee and Gordon's Mill, which contained the area's first general store, was situated near a blacksmith shop and stagecoach stop. From 1840 to 1847, Gordon built his Doric-columned brick house (known today as the Gordon-Lee Mansion), which overlooks Crawfish Springs. The area was settled by many other farm families and life was busy and fruitful in the fertile valleys, until even this remote part of the South was visited by the sounds of cannon and guns during the American Civil War. The Battle of Chickamauga, named for nearby Chickamauga Creek, was fought on September 19–20, 1863. It involved more than 150,000 soldiers of the Northern and Southern armies. Before the battle, Union Gen. William Rosecrans put his headquarters at the Gordon Lee Mansion. During the battle, wounded and injured soldiers were cared for in the home and nearby buildings. Many Union doctors remained behind to care for their patients after the Southern victory. Parched soldiers of both sides drank from the town's namesake springs. Crawfish Springs was the site of an 1889 reunion of veteran soldiers, Northern and Southern, who had fought in the Battle of Chickamauga. Called
