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. During the Battle of Stone's River, December 31, 1862, to January 2, 1863, the battery was assigned to Brigadier General Joseph Wheeler's Cavalry Brigade. During the skirmishing leading up to the battle, the battery fought as independent sections under Lieutenants J.P. Bryant, and J.W. Calloway. Lieutenant Bryan lead one gun of one section which accompanied Major General John C. Breckinridge's attack on the Union left flank on January 2, 1863. During the Tullahoma Campaign, which followed the Confederate defeat at Stones River, the battery was assigned to Brigadier General William T. Martin's Brigade of Wheeler's Cavalry. In April 17, 1863, Brigadier General William T. Martin ordered the battery to exchange two of its old guns for new howitzers. Martin was concerned that the two guns being turned in could not be moved due to their poor condition. Captain Wiggins compiled service records contain correspondence relating to Brigadier General Martin's orders to turn in two of his guns. Wiggins reports that he had two rifled guns that had become very inaccurate due to the rifling becoming worn.
