Stevens returned to command in time for the Bristoe Campaign and the Battle of Mine Run, remaining in the artillery brigade of I Corps. When the Army of the Potomac was reorganized before the Overland Campaign of 1864, the 5th Maine Battery was assigned to the Reserve Artillery. In that formation it took part in the Battle of the Wilderness, although little engaged. The battery was assigned to the artillery brigade of VI Corps under MG Horatio G. Wright on May 17, during the Battle of Spotsylvania Court House. The battery supported infantry of VI Corps during the Battle of North Anna as well. At the Battle of Cold Harbor, Stevens was able to place his guns in earthworks near the Gaines Mill Road to support the VI Corps line. On June 3, Stevens had his gunners fire canister at the Confederate works to support Wright's attack. Stevens also reported silencing a Confederate battery.
