Help with Civil War military records?

[ELCore]

My mother recently turned 80, and for the occasion I decided to attempt a genealogy. I believe one James Runnels Dowler was my great great great grandfather. (I say "believe" because this genealogy stuff is tricky!)

From fold3.com, I have some records of his service in the Civil War: muster-in, returns, muster-out, and pension applications.

I think the terms and conditions do not allow me to post the images here, but I can attempt a transcription if anybody here has the knowledge and desire to help me to understand them better. Or, perhaps, somebody can refer me to another site.

Thanks.
