A clasp inscribed "Relief of Mafeking" will be granted to all troops under the command of Colonel Mahon, who marched from Barkly West on May 4th, 1900, and all troops who were under Colonel Plumer's command between October 11th, 1899, and May 17th, 1900, both dates inclusive, and who were south of an east and west line drawn through Palachwe.
It seems surprising that this one - as a single clasp - does not surface more often. Just now I had a quick run through my old Kaplan roll for the RofM and there are quite a few of the Rhodesia Regt. who are down only for that clasp. I suppose some might have served with other units later on; Kaplan does show a number did so serve. However that still leaves quite a few. Any ideas?
