Washington Light Artillery was originally organized to be attached to the Hampton South Carolina Legion. However, it never served with that command. After being stationed in South Carolina, the unit moved to Virginia and was assigned to Stuart's and R.P. Chew's Horse Artillery. It fought with the Army of Northern Virginia from the Seven Days' Battles to Cold Harbor, then was involved in the Petersburg siege south of the James River. Later it joined B.C. Manly's Battalion of Artillery in the Army of Tennessee and was active in North Carolina. The company lost 1 killed and 4 wounded during the Seven Days' Battles, had 4 officers and 75 men at Gettysburg, and surrendered on April 26, 1865. Captain James F. Hart was in command.
