Continuity mistake: When Bromhead is standing on the burning roof firing his pistol at the Zulus running about below, you can see there's no gun smoke or muzzle flash from the barrel. It looks as if he's just pointing it around.
Factual error: The Swedish missionary Otto Witt is portrayed as a drunkard who encourages the soldiers to abandon their posts. In reality Otto Witt helped the defense by helping to build the barricades. He later volunteered to assist as a lookout on the nearby hill. He departed before the battle to join his wife and two daughters at a nearby farm.Robin Allen
Continuity mistake: During the lull before the attack on the hospital, when Pte. Hook walks over to the doorway to speak to somebody, his suspenders are dangling down from his waist. A minute later, when the camera angle changes, his suspenders are suddenly up over his shoulders. Then, when the camera angle changes again, his suspenders are back down again.
Continuity mistake: During one of the first Zulu attacks, a local is walking behind Chard carrying a box of ammo with a bayonetless rifle slung over his shoulder. The man is hit by a bullet and goes down. Chard quickly checks the man and then realises he's being charged by three Zulus. He shoots the first with his pistol, runs out of ammo so makes a grab for the dead mans rifle which now suddenly has a bayonet attached to it.
Deliberate mistake: The Zulus sniping on the defenders from the mountain are armed with Martini Henry Rifles implying they were taken from the dead at Isandlwhana. This couldn't have happened as the Zulus attacking Rorke's Drift did not fight at Isandlwhana, they were only the reserves. The looting of the camp was done by those who fought there. The Zulu snipers used old muskets.
Factual error: Conversely Corporal Allen, portrayed as the model soldier, was demoted from sergeant (his previous rank) for drunkenness before the battle.
Factual error: Henry Hook in fact retired from the Army as a Sergeant-Instructor, hardly the barrack-room lawyer as which he is portrayed.
Continuity mistake: During the battle in the hospital, when Hook bayonets a Zulu up against the wall, the bayonet clearly goes under the armpit, not through as the mark left on the wall afterwards would suggest.
Factual error: At the begining of the film, Chard and Bromhead do not know one another and during the preparations for the defence it is indicated that Chard and Commissary Dalton do not know each other. Chard had actually been stationed at Rorke's Drift for several days before the battle and knew both Bromhead and Dalton.
Factual error: Several of the Martini-Henrys shown in the movie are later models that could not possibly have been present at Rorke's Drift. These include the Mark III, Mark IV, and several variants of the Francotte Cadet and Boer ZAR Contract Westley-Richards (neither manufactured until 1895) along with Bromhead's hunting rifle. One of the Zulus is even carrying a Martini-Enfield .303 Carbine, not manufactured until 1899.
Continuity mistake: One shot of the Zulus attacking is shown in reverse - all the Zulus appear to be left handed.
Factual error: Another commissary (senior to Dalton) and an army chaplain (who distinguished himself by handing out ammunition during the battle) were also present in the garrison.
Factual error: When private Hitch is wounded, he is shot in the leg. He was actually shot in the shoulder. The bullet shattered his shoulder blade and he was invalided out of the Army as a result.
Factual error: The webbing the British soldiers wear is incorrect. They are wearing Slade Wallace which is 1888 onwards. They should be wearing 71 Valise pattern.
Continuity mistake: Colour Sergeant Bourne goes one on one with a large Zulu warrior and kills him. Later, this same Zulu warrior is alive & well.
