The September 1864 Civil War Battle of Sulphur Trestle, in Limestone County, cut a crucial Union supply line and was a victory for the Confederate forces under Gen. Nathan Bedford Forrest. The engagement over the railroad bridge was the bloodiest to take place in north Alabama.
By 1864, Union forces had advanced deep into Confederate territory, even into Alabama. The food, ammunition, clothes, and weapons required to continue their campaigns were transported primarily via railroads to troops fighting the war. One of these, the Alabama and Tennessee Railroad, ran south from Nashville, Tennessee, through southern Tennessee and northern Alabama to Decatur, Morgan County, on the banks of the Tennessee River. From Decatur, the railroad connected with another line that extended east to Chattanooga. This line thus provided a continuous route for supplies that were offloaded from boats on the Cumberland River in Nashville and then sent via train to support Union forces in Chattanooga.

On Saturday, September 24, 1864, Confederate general Nathan Bedford Forrest's troops, about 500 mounted cavalry and infantry, who had just enjoyed a victory over a much larger force of Union troops in the town of Athens in Limestone County, six miles south of Sulphur Creek, advanced north with the intent of destroying the trestle. Confederate scouts engaged in a brief skirmish with a Union patrol late on Saturday evening, and the Union forces withdrew into the fort's perimeters; the opposing sides exchanged gunfire sporadically throughout the night. Forrest's troops were in position and ready for battle before dawn the next day. In the early hours of Sunday morning, September 25, Forrest's artillery opened fire against the earthen works.
The approximately 1,000 Union troops garrisoning the fort returned fire, but they had only two 12-pound artillery pieces versus Forrest's eight cannon. Although the Union defenders had the advantage of a fortified position, Confederate artillery and sharpshooters were able to fire down on the Union troops from the higher ground surrounding the fort. From their superior positions, Forrest's artillery reportedly poured 800 rounds into the fort in a little more than two hours. Union troops tried to take cover in the fortification's buildings, but the artillery fire either destroyed the structures or set them afire.
About mid-morning, a brigade of troops under the command of Col. David Campbell Kelley charged across the open field on the valley floor, losing a number of soldiers in this advance. Unable to breach the fort's defenses, they took up positions in a ravine within 100 yards of the fort. From there they fired continually at the defenders. The tide was clearly in the Confederates' favor. The cannon fire and the deadly accuracy of Confederate sharpshooters had decimated the Union ranks.

The Sulphur Creek trestle bridge is believed by some scholars to have influenced Civil War veteran and writer Ambrose Bierce's story, "An Occurrence at Owl Creek Bridge." Although the story recounts the hanging of a southern sympathizer in Tennessee and not a battle, the location described in the story strongly resembles the Sulphur Creek scenery, which Bierce had visited as a member of the Ninth Indiana Infantry while helping to repair the railroad in 1862. The gap that the trestle spanned was later filled in with dirt, and the railroad bed is now part of the Richard Martin Trail that runs from Veto at the Tennessee boarder, south to Hays Mill.
