Civil War veterans plot in Oakwood Cemetery, Allegan, Michigan

There is a curious collection of a half dozen civil war veteran burials right at the first entrance off of Western Avenue (Kellogg Street in the cemetery) to Oakwood (if you're coming from town).

What makes this group of government headstones curious is this space doesn't seem to be a specially designated area just for veterans nor does it appear to be connected with any GAR post. It's just a group of unrelated (?) possibly indigent veterans.
