From New Orleans, in May 1861 he was Captain of Company D (Virginia Guards of Orleans Parish) of the 7th Louisiana Infantry. By May 1862 he was Major of the Regiment. He was promoted to Lietenant Colonel in June on the death of Lt. Colonel DeChoisel, and was appointed Colonel to replace Colonel Hays who was promoted to Brigadier General on 22 July 1862.

The remainder of the War:

He remained in command of the Regiment, including service at Fredericksburg, Chancellorsville, and Gettysburg, through late 1863. He was captured in action at Rappahannock, Virginia on 7 November 1863, and passed through the Old Capitol Prison, Washington DC, on 11 November enroute to Johnson's Island, Ohio. He was a prisoner there for the remainder of the War until paroled 12 May 1865.

He was Lieutenant Governor of Louisiana (1872). In 1874 he may have been a leader of the "White League", a vigilante group which temporarily displaced the (Republican) Reconstruction government in Louisiana by armed action known as the "Battle of Liberty Place" - in the city of New Orleans, then the state capital - 14 September 1874.
