On the day before the main battle, November 23, Grant took on the main lines surrounding the city before advancing to the mountain, where the battle officially began on the morning of November 24. General Joseph Hooker then took over for the Union to make an assault on the mountain, although he did not plan to actually take control of the mountain itself. Along with men from General John W. Geary's division from the Twelfth Corps, the Union was able to capture a nearby Confederate post with no gunfire exchange thanks in part to the heavy fog that day. Unfortunately for the 1,200 Confederate troops stationed on or around the mountain, they were no match for the 12,000 Union forces that came for Lookout Mountain. Around 2:00PM that day, Rebel soldiers left the mountain in defeat.
Later that evening, General Bragg held a meeting with his fellow generals and decided to begin reinforcing nearby Missionary Ridge since they have lost the mountain. The following day, however, saw another Yankee victory after Grant launched another attack that saw the Confederate lines weaken and finally freed Chattanooga from Confederate control. This campaign soon proved to be the beginning of the downfall of the Confederacy as Grant soon announced the Chattanooga-Ringgold campaign in the days following Lookout Mountain and laid the groundwork for Sherman's famous March to the Sea the following spring.
Visitors to the park and museum can get an up-close view with cannons used during the battle as well as an incredible view of downtown Chattanooga from atop the mountain. The museum allows you to hear the tale of the battle through a miniature model that lights up whenever discussing s skirmish or full fledged firefight. Seeing the city from such an enormous height will give those a feeling of why the battle has earned the nickname the Battle Above the Clouds.
