THE CAMPAIGN FOR CHATTANOOGA
On August 16th, the Union army started their forward movement. Thomas and McCook moved their corps down to the Tennessee River at Bridgeport. Crittenden moved down the Sequatchie Valley, having troops from just north of Jasper to a point above Pikeville. A part of the latter’s corps, (Wilder’s and Wagner’s Mounted Infantry) took positions along Walden’s Ridge and Signal Mountain where they were in plain view of the Confederates in Chattanooga. Numerous demonstrations were made at these points to attract the attention of the Confederates and to make them believe they were attempting to cross the river at some point above the city. They would beat on empty barrels to imitate the rolling of supply wagons. They also built huge bon-fires and would march back and forth in the flare of them. Buglers were placed at distant points where they would strike a few notes at regular intervals. They even sawed planks, boards and pieces of logs to float down the river to give the Confederates the impression they were building a pontoon bridge at some point above the city. On August 21st, a part of Wilder’s brigade advanced to Stringer’s Ridge where they shelled Chattanooga with artillery. One shell landed in front of the First Presbyterian Church at Seventh and Market streets, while services were being conducted. Some reports claim that a little girl had her leg broken by a piece of shell. However, according to the report of Confederate Gen. D. H. Hill, several women and children were killed. Today, Chattanooga’s tallest building, the Hamilton National Bank, stands on this site. The shelling of the city showed that the Union troops were on the immediate front of the Confederates. As a result, Cleburne’s division was sent to Harrison, and then distributed at every ford and ferry between the mouths of the Chickamauga Creek and the Hiwasee River—a distance of at least 50 miles. These troops were so placed in order to guard against any possible crossing by the Union troops. All of these positions were covered by rifle-pits and batteries. With the Confederates’ attention drawn in this direction, the main body of the Union army effected a crossing of the river at Bridgeport, 30 miles below Chattanooga, between August 29th and September 4th, unmolested. Thomas crossed over the Sand Mountain to Trenton, Georgia, after much difficulty.
When Bragg learned that the Union army had crossed the river below him he evacuated Chattanooga during the 8th and 9th of September, moving 26 miles southward to LaFayette, Georgia, behind the Pigeon Mountains. This movement was made in order that he could protect his line of communications and his base of supplies, his base being Atlanta. As the last of Bragg’s army was leaving the city on the morning of September 9th, the 92nd Illinois Mounted Infantry made a reconnaissance on Lookout Mountain. They then entered the city. Crittenden’s corps followed the railroad to Ringgold, then westward to Rock Springs in pursuit of the Confederates. At this latter point, Crittenden was directly between Bragg and Chattanooga.
