Chickamauga and Chattanooga National Military Park Historian Jim Ogden will lead a hike on Saturday, from 9:30-11:30.
Mr. Ogden will talk about the Union Army's effort in late October 1863, that opened a new supply line into then-besieged Chattanooga.
The 2.5-mile round trip walk will go through the historic gap in Stringer's Ridge and down to the banks of the Tennessee River at Brown's Ferry.
Meet at the Chattanooga Bakery parking lot at 900 Manufacturers Road.
