Best after action reporting/reading (books or vintage accounts)

Forgive me if this belongs elsewhere but I didn't see a more appropriate forum area. I was wondering if anyone could recommended some reading options on the history and status of the Isandlwana battlefield after battle. I've read a few accounts here and there, mostly about the army's night camp on the site but I was hoping for something that focused on the state of the field and casualties immediately after the battle, the burials, exhumations, memorials, and history of the site itself. I've found slightly more information on this concerning Rorke's Drift but I am open to reading on the same topic for any of the Zulu War sites. Cheers,
