Anglo Boer War - Is there any way to get more information

Is there any way to get more information relative to the casualties which were comparatively few?. According to the Memorial of Herbert Campbell Maw, He Died on 14th May 1906 having been killed while serving with the Natal Forces in the Zulu Rebellion. I am a direct relative of Herbert and currently have in my possession his QSA Medal (4 clasps) and Natal Rebellion Medal (without clasp).
