In 1862, Union troops under the command of Gen. Ormsby M. Mitchel occupied Athens and work soon began on the construction of Fort Henderson. (Mitchel previously helped plan the daring Union scheme to steal a locomotive and destroy rail lines between Atlanta and Chattanooga that became known as the "Andrews Raid" and "The Great Locomotive Chase.") Henderson was designed as a five-sided earthen fortification. Its all-white garrison was replaced with the 110th U.S. Colored Infantry Regiment in 1863. Work on the fort continued with the construction of multiple wood-frame buildings and underground bombproof shelters, the digging of an 18-foot moat, and the encirclement of the fort with a network of abatis, or pointed wooden stakes. As Sherman's army marched through the South in the fall of 1864, Confederate cavalry under Forrest launched a raid on Athens to destroy the Nashville-Decatur Railway, which was part of Sherman's extensive supply lines.
On September 24, 1864, Confederate forces surrounded the garrison at Fort Henderson and Forrest convinced the garrison commander, Col. Wallace Campbell, that he was surrounded by a far larger force. Seemingly outnumbered, Campbell surrendered his entire 900-man garrison. The next day Forrest's men would lay siege to another fort protecting a rail line, this one at Sulphur Trestle Bridge just south of Elkmont, and also capture a much larger Union force. It was north Alabama's bloodiest battle and would also add to the aura surrounding Forrest and his military prowess. Soon thereafter, his forces abandoned the fort and moved north to continue their raids. Union troops quickly reoccupied Athens after his departure.

The Athens-Limestone Community Association currently owns the property on which the fort and former school stands, to the east of Trinity Park on County Road 29. The organization was established in 1981 with the aim of preserving the fort and the school and promoting their history. Though most of the school's original buildings no longer exist, the auditorium and a section of the school still stands as does a portion of the fort's earthworks. The ALCA is currently raising funds to rebuild the fort and create walking trails, interpretive markers, and a park and establish a museum. The ALCA is in the midst of a three-phase restoration program that includes the opening of the Pincham-Lincoln Center community center in 2015 in a renovated portion of Trinity High School, the restoration of Fort Henderson, and the renovation of Trinity High School's band room into an archives and museum.
