It's the same for me too, alas...
But for the question n°3, it's the Lt The Hon.William Vereker, Because:
Early in the battle of Isandhlwana, he lost his horse when the 24 th collapsed,he found another ,and what about to ride off when one of his black infantryman claimed it.Vereker gave up the horse,and stayed to be killed in the camp.
He sacrifices himself for a single black warrior, all in 1879, what a beautiful soul ...
For the question 2, it's the Mtuyisazwe regiment, as they are incorporated into one of two regiments of the most aggressive (uKhandempemvu) and according to my tastes, they are the most beautiful shields ...
For the first question, going to the troop Edentale of the NNH, that are really too original, even compared to other black cavalrymen ... and have shown at Kambula, how they were smart ...
Cheers
