The film gives a good overall version of the events although the way they are portrayed in the film is not totally accurate. This doesn't detract from the impact of the film. The film does portray also the courage of the Zulus. It must have taken much for them to attack against a defended position, bare footed, and in many cases only armed with an assegai and a shield. It is unlikely that the weapons used against the defenders were taken from the dead at Isandhlwana since Prince Dabulamanzi kaMpande and his regiment had not taken much part at Isandhlwana but wanted to have some glory.
Some details ought to be mentioned though.
Rev. Witt was not a drunk. There were two parties who warned the post of the possible approach of the Zulus and told of the events at Isandhlwana . The command at the station was not decided between Chard and Bromhead on the basis of date of commission, it was decided by Capt. Having then checked the army list Spalding said to Chard 'I see that you are senior, so you will be in charge. The Natal Horse Contingent which arrived at Rorke's Drift from Isandhlwana were actually deployed for defence but thought that their position was useless and then withdrew.
