Best thing to do is get a copy Art Bergeron's book on Louisiana Confederate Units. It will contain a listing of command and company officers, for both the Confederate Guards Response Battalion, that in late 1863 was blended in to the Consolidated Crescent Regiment. Would suspect you might these names here.
Also, according to Booth's Book (a listing of Louisiana Soldiers) it shows him sick in Richmond in July and August of 1862. Being discharged soon there after. So he may not have been a 'combat effective' soldier, but as a pre-war shoemaker, could help the war effort by making and repairing shoes. Here is what Booth's Book said.

Interesting to read that he seems to drop off the scope and no record, at least in Booth's that he was ever in the Consolidate Crescent Regiment. Please note that Booth's, while it has a lot of information, is lacking is some areas.
