On the Main Menu we haveBoer War 1899-1902. Could I suggest you add 2 categories : First Boer War (1880-81) and Anglo Dutch/Boer Skirmishes (Pre 1880)
This last one would be the home for British Occupations of the Cape, Congella, Boomplaats, etc
I second Henk's excellent suggestion. It would separate the lineage of the two numbered Anglo-Boer Wars from that of the Frontier Wars. The former were fought between two competing groups of Colonists in South Africa, while the latter were between the Colonists of both types and the indigenous tribes of the country.
