Elliott served in the Confederate States Army within South Carolina from the beginning of the Civil War in 1861 until the spring of 1864, advancing from captain to colonel. On July 30, 1864, Elliott's brigade was defending the Confederate line at Elliott's Salient near the spot the Union Army's mine blew, which precipitated the
Battle of the Crater. Elliott was asleep in a "bombproof" near the line and awakened to find the destruction and chaos surrounding him. Finding no troops nearby since he was close to the site of the explosion, he went to find his remaining men and organize a counterattack in line with a previous plan to deal with such a mine attack. After finding two of his regiments mainly intact, Elliott led them forward, positioning them to defend against an assault and to counterattack. Elliott joined
General Joseph E. Johnston's
Army of Tennessee in North Carolina, where he led a brigade of former Charleston defenders and largely untested soldiers. From January 2, 1865, through March 1865, the brigade was in Taliaferro's division of Hardee's corps. At the point where the Confederate retreat halted, in the middle of an artillery barrage, Elliott tried to reform his brigade for another assault, despite receiving a piece of shrapnel in his leg. In the event, Confederate commanders saw that the brigade was too shaken to make another attack and they were ordered simply to kneel or lie down and hold their ground. Elliott had again received another serious wound. Elliott had been sent home to convalesce from his latest wound before Johnston's surrender.
