November 23, 1863 – Major General Ulysses S. Grant began efforts to break his Federals out of Chattanooga by assaulting forward Confederate positions at the base of Missionary Ridge.
By this date, Grant was finally ready to break the two-month siege of Chattanooga, conducted by General Braxton Bragg’s Army of Tennessee. According to Grant’s plan:
- Major General William T. Sherman’s Federals would launch the main attack on the Confederate right on Missionary Ridge, north of Chattanooga
- Major General George H. Thomas’s Federals would demonstrate against the Confederate center from within Chattanooga
- Major General Joseph Hooker’s Federals would await developments in front of Lookout Mountain, southwest of Chattanooga
As the day began, Sherman’s three divisions, along with one of Thomas’s divisions, were still on their way to their attack positions.
Meanwhile, Major General Bushrod R. Johnson’s Confederate division was moving off Missionary Ridge, having been ordered by Bragg to board trains at Chickamauga Station and reinforce Lieutenant General James Longstreet’s Confederates laying siege to Knoxville, to the northeast. Major General Patrick R. Cleburne’s division was to follow, leaving Missionary Ridge virtually undefended.
Confederate deserters soon filtered into the Federal lines and claimed that their comrades on Missionary Ridge were retreating. When Grant received this news, he wrote, “The truth or falsity of the deserters should be ascertained at once. If he is really falling back, Sherman can commence at once laying his pontoon trains, and we can save a day.”
But when Grant learned that Sherman was not yet ready to attack, he directed Thomas to proceed against the Confederate center anyway. Thomas deployed two divisions of Major General Gordon Granger’s IV Corps, supported by XI Corps under Major General Oliver O. Howard. These Federals, totaling about 14,000 men, were to conduct a “reconnaissance in force” on Orchard Knob, a 100-foot-high foothill on Missionary Ridge, in the front-center of the Confederate line.
Granger’s two divisions, led by Major General Philip Sheridan and Brigadier General Thomas J. Wood, assembled in full military dress as if to conduct a formal review about a mile in front of the Confederates’ forward line. Grant, Thomas, Granger, Howard, and Assistant Secretary of War Charles Dana watched the “parade” from Fort Wood, in the Federal rear.
The Confederates, part of Major General John C. Breckinridge’s corps, came out of their defenses to watch what they thought was a “military pageant.” Breckinridge watched with Bragg from atop Missionary Ridge. As the Federals moved across the open plain toward the Confederate line, Bragg dismissed the movement as a review. Breckinridge said, “General Bragg, in about 15 minutes, you are going to see the damnedest review you ever saw. I am going to my command.” Still skeptical, Bragg nevertheless wrote Cleburne, who was loading his troops on trains at Chickamauga Station, to “halt such portions of your command as have not yet left at Chickamauga.”
At 1:30 p.m., an hour after the “parade” began, a cannon fired from Fort Wood signaling the Federals to charge the enemy line. They advanced without artillery support to further deceive the Confederates into complacency. The Confederates hurried back to their defenses, but as the Federals came on, each defense line collapsed into the next until the Confederates were pushed all the way back up Missionary Ridge.
The Federals planted their flag on Orchard Knob around 3 p.m. Thomas notified T.J. Wood via signalman, “You have gained too much to withdraw. Hold your position and I will support you.” Major General Francis P. Blair, Jr.’s division advanced on the Federal left and XI Corps came up on the right to secure the line. This enabled Thomas to bring his entire army (i.e., the Federal center) up to the foot of Missionary Ridge.
Bragg sent another, more urgent, message to Cleburne: “We are heavily engaged. Move rapidly to these headquarters.” At least 5,000 Confederates of Johnson’s division and part of Cleburne’s had already left for Knoxville, but at least Bragg still had the remaining 6,000 to come back and defend his right. Had Grant waited another day to advance, those 6,000 would have been gone as well.
Bragg had initially believed that the real Federal threat would be to his left at Lookout Mountain, but now he realized that the Federals planned to attack his right. He therefore ordered Lieutenant General William Hardee to pull his entire corps off Lookout Mountain except for Major General Carter L. Stevenson’s lone division.
Stevenson argued that he lacked the manpower and knowledge of the terrain to put up an adequate defense in case of attack. Bragg assured him that he would send reinforcements if Stevenson needed them, but Stevenson most likely would not since the main attack would probably come against the Confederate right. Bragg positioned Cleburne’s returning troops on the extreme right, near Tunnel Hill.
Grant moved his headquarters to Orchard Knob and modified his strategy based on this day’s unexpected success. He had initially planned to launch his main attack against the Confederate right, but now he ordered Hooker (with Brigadier General Peter J. Osterhaus’s division of Sherman’s army) to demonstrate against and possibly capture Lookout Mountain on the Confederate left. This would enable Hooker’s Federals to enter Rossville Gap and threaten the Confederate rear.
