[1] Louis Hébert graduated from the United States Military Academy in 1845 and was assigned as a brevet second lieutenant to the construction of Fort Livingston, Louisiana.

[3] He then served in Confederate operations in the Cape Fear District in North Carolina first in artillery and then as chief engineer of the department.

[3] After the war Hébert was an editor and publisher of a local St. Martin's parish newspaper, Iberville South, and taught at several private schools.

[3][4] Louis Hébert died January 7, 1901, on the east bank of Bayou Teche, 6 miles (9.7 km) north of Breaux Bridge, Louisiana, where he was interred.

[3] Because his burial site was located on private land, with assistance from the Sons of Confederate Veterans on October 26, 2002, Hébert's remains were disinterred and moved to St. Joseph Catholic Cemetery in nearby Cecilia, Louisiana.
