The battery did not participate in the Kentucky Campaign, from June to October, 1862. The unit's muster roll for the period July to August 1862, and again in October 1862 list the battery's station as Camp Randolph, Georgia. It appears that Roberts' Battery was transferred from Liddell's Brigade to the reserve artillery of the army at the reorganisation at Chattanooga prior to the invasion of Kentucky although no definite order to that effect can be found. Swett's Mississippi Battery was assigned to Liddell instead. The battery then became part of The Army of Middle Tennessee when that unit was organized in October 1862. It was then transferred to cavalry service und Brigadier General Nathan B. Forrest, probably in late October. Major Rice E. Graves, Chief of Artillery of Major General John C. Breckinridge's Army of Middle Tennessee, reports on 11 November 1862 that Roberts' Battery along with Freeman's Tennessee Battery had been assigned to Forrest's Cavalry Brigade. The battery at this time comprised 2 six-pounder guns and 2 12-pounder bronze howitzers. Graves also provides information on the disposition of the batteries that made up Montgomery's Battalion. Brigadier General Forrest praised the conduct of Captain J.H. Wiggins, commanding Roberts' Battery in his report of the action at Nashville on 5 November 1862. Sometime prior to The Battle of Stones River the battery was transferred from General Forrest to General Wheeler's Cavalry.
