Factual error: Lieutenants Chard (Stanley Baker) and Bromhead (Michael Caine) and nearly all the soldiers defending Rourke's Drift are clean-shaven. Between 1860 and 1916 all British army personnel, from Field Marshall to Private were not allowed to shave their upper lips. The army rigidly enforced this rule. Thus, all the soldiers defending Rourke's Drift sported moustaches. Many had beards, too.
Factual error: The film seems - through dialogue from the soldiers and the preacher - to suggest that the Zulus were the aggressors ("savages") in this in the actual Anglo Zulu war. In fact the British had crossed illegally into Zululand to provoke a war. The crossing point of the Buffalo river into the Zulu kingdom was Rorke's Drift - and so the Zulu attack on it was not from savage whimsy, but came from a Zulu contingent eager to see action as they were reserves at Isandlwana.
Answer: Absolutely correct. This exact scene is in my DVD of Zulu. They may have changes when the TV version aired, but this definitely in the original.
