"Union Occupational Army" 1865

I just read an account in Ouida Starr Woodson's "Within the Bend" series (book two): "The 5,000 strong Union Occupational Army boarded steamboats in Mobile in April of 1865....The large force was put ashore at Claiborne in Monroe county to march overland and rendezvous with the boats at Bridgeport Landing in Wilcox County." There is more to that small reference in the book, but I am wondering if anyone has more information, or a book about it with more detail? This would have been before the official end of the war in Alabama, I think, and may be considered the start of reconstruction, at least in that part of the state. Am I right about that? Anyone with more information? Thanks
