ANSWER
I can attempt.   In the Western Transvaal itwould have been possibly Captain Kraus or Brigadier Loots.   Inthe Eastern Transvaal it could have been Captain Dietlis(?). In the far North I don't know, I can't think who it might havebeen.   I don't know about the Northern Cape.   Then in my ownregion it would have been a number of different persons, it couldhave been Captain Van Jaarsveld or Captain Loots, it could havebeen either of them.
