The unit was ordered to Centreville where it joined the Artillery Reserve
under Col. W. Pendleton. In April 1862 they moved back to Richmond
and thence to Yorktown. Prior to the Seven Days battles, Pendleton
reorganized the Reserve Artillery and placed Captain Kirkpatrick's
Battery in William Nelson's Battalion. In 1863 it was placed in the Second
Corps under Lee. At the end of May 1864, Kirkpatrick's men had not
had a single death due to enemy action. However on June 2 at Cold
Harbor the battery was caught in fire that left six men dead or mortally
wounded and nineteen wounded. The battery was refitted and moved via
Lynchburg to the Shenandoah Valley. Nelson's units took part in the battles
of Monacacy Junction, Third Winchester, Fisher's Hill, and Cedar Creek.
On March 2 the army was overrun and most of its members were captured
at Waynesboro.
