I am still working on my Great Great-Grandfather's unit, the 13th/16th Battalion Georgia Calvary.
Relatively speaking, there were a very small unit, between 2500-3000 men. I am endeavoring to extract all of the information contained in each man's CSR that has survived.
Some CSR's have very little data, some have 20-50 pages, for example, my ancestor's CSR only contained 1 card and on that card his name was spelled incorrectly. My problem is reading the hand writing on the documents, because it has poor penmanship or because they needed to sharpen the pencil because the writing is so pale.
I am grateful for all of the knowledgeable people on the various boards for their able assistance.
