Thank you for that proposal. You are correct, and my apologies for always being fixated with Natal. There is a precedent for starting the numbering that early. The Frontier Wars in the Eastern Cape are often thought of as the three for which the SA 1853 Medal was awarded, but, as the heading for this section of the forum indicates, they actually spanned the period from 1779 to 1879, and so should be numbered accordingly.
To the Cape Occupations and Congella could also be added the Battle of Boomplaats and its aftermath, since that too was a prelude to the two currently recognised Anglo-Boer Wars. I suppose it could be argued that the preliminaries were battles rather than wars, and Britain's enemies were then called 'Dutch' and not 'Boers'.
