1st Regiment, Louisiana Heavy Artillery (Regulars)(Confederate)
This unit was organized 5 February 1861 and was part of the Louisiana State Army, later transferred to the Confederate Regular Army. The regiment was headquartered at the New Orleans Barracks, but companies served at various forts defending New Orleans. In May of 1862, the regiment was ordered to Vicksburg where they fought until surrender in July 1863. Grant, not wanting to care for 30,000 prisoners of war, immediately paroled the unit. By January 1864, the regiment was in Mobile, Alabama. After brief stints in Meridian and Tupelo Mississippi, the unit returned to Mobile and garrisoned the batteries until surrender 8 May 1865 at Cuba Station, Alabama. The men were paroled at Meridian as part of Taylor's army.
"Units of the Confederate States Army" by Joseph H. Crute, Jr. contains no history for this unit.
Companies in this Regiment with the Counties of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first. Many Louisiana units were known by a local designation or nickname. Follow both the regiment and company name as well as other organizational names.
