George:

The only copies of the enlistment oath that I have seen was in the CMSR for men sworn into two Louisiana regiments (Gray's 28th and the 31st) who were enlisted in 1862. I have none for the men of the 12th Louisiana enrolled in 1861. Point is these enlistment papers should be in the individual CMSR already - they are not in a separate file as far as I know.
