Royal Navy and ships

Hello All - I have managed to purchase a QSA / WWI trio to Alfred Harry Wallis. His QSA is named Capt AH Wallis, Southern Rhodesian Volunteers. His 1914-15 Star to Capt S.A.E.C, and his BWM & VM to Lieut. I have his MIC and his WWI service is confirmed. Any info on his Boer War service would be very much appreciated. best regards Thomas
