Enlistments

Early in the war many Confederates enlisted for twelve months.

The Confederate Conscription Act of 1862 required men to serve three years.

My question:

Were the initial one year enlistee's required to serve an additional two years, which would equal three, or three years from the time the law was enacted ?

I've read much conflicting info on the above, even that later on men were required to serve for "the war" making the three years rule meaningless.

Thank you,

D.W.
