12th Battalion, Louisiana Heavy Artillery (Confederate)

Organized near Yorktown, Virginia in 1862. This unit consisted of men from three states. They served in Richmond, Virginia and then Port Hudson, Louisiana in 1862. Following the siege of Port Hudson, the officers were sent to northern prisons and the men either went home or to parole camps. Some men reorganized in late 1863 in Mobile, Alabama, but were considered an independent unit. Some men continued to serve in the 1st Louisiana Heavy Artillery. What remained of the battalion surrendered at Meridian, Mississippi on May 8, 1965.
