Transferred as part of Jubal Early's command to the Army of the Valley, the battery participated in Early's raid on Washington, fighting in numerous engagements, including Monocacy and Cedar Creek. Captain Massie was mortally wounded in September 1864, and Capt. Charles G. Snead led the remaining artillerymen for the balance of the war. The battery was then temporarily disbanded around Christmas, 1864, to conserve supplies. Those who stayed behind were captured at the Battle of Waynesboro, Virginia on March 2, 1865. After capture, they were marched to Stephensons Depot. They were then loaded onto box cars and shipped north to Baltimore, Maryland. Their final destination was Fort Delaware Prison. Members were paroled and released between June 21 and 22, 1865.
