He seems to be counting earlier wars or battles in the naming of "Boer Wars". Whereas at least in the English speaking places I've lived, we refer to two, the first being 1880-81, the second being 1899-1902. Any other battles or wars use different naming rules.
Does he now? under what circumstances was Natalia(Natal) annexed by the British? what conflict was that?
Did the Boers buy land into the area before its official annexation by the British?
