I’ve been to Rorke’s Drift and it was an interesting site. The Lutheran Mission is still there and Isandlwana is a few miles across the river and up the road. Fortunately for the Brits, the Zulus were unfamiliar with the rifles they picked up from Isandlwana as there was bluffs behind looking down on the Brits position at Rorke’s Drift and in the hands of skilled shooters shooting at the defenders would have been like shooting at fish in a barrel. Hollowood did a later move after Zulu called Zulu Dawn which was about the wiping out of the Brit’s regiment at Isandlwana. For one who wants to watch both just flip the sequence and watch Zulu Dawn before Zulu to get the complete historical picture Hollowood style.
(I’ve corrected the spelling of Isandlwana in Morgan’s passage.)
