First of all I would like to commend Julian & Frederic for their latest assays.
If you think about it, over that past couple of years, more first hand accounts (of Isandlwana) have been discovered and their contents put into context.
If you divide the battle into 3 or so stages – Discovery & Preliminary movement (A), Zulu assault (B) and say, British retreat or last stands (C)
An awful lot now seems to have come to light about the latter stages of the battle(C) - both for some individuals and for various units involved – even down to naming a number of individuals in AWDs last stand and many myths (or rather misconceived ideas) have been laid to rest – such as the location of Anstey’s stand (if there was such a thing, in the conventional 'last stand' idea).
Quite a lot is known about the actual battle its self (B) - hopefully Symon's Part 2 will add more to the knowledge pool
However ‘A’ still poses a problem – (perhaps because the small number of British who witnessed the discovery of the impi) and they left few accounts for posterity and it is hard to decipher the events and/or locations
The last big theory was TMFH but that still causes debate.
Maybe sometime in the future a dusty old letter will be found that helps throw some light onto that section subject
