That would be Caledon River not Caledonian Ranger

I found it quite interesting that 'the recruit was offered free passage from a port in this country to a port in British South Africa'

Have you any idea what or where 24 Troop was? He was transferred from there the The Caledonion River South Office. Were these places in the Cape Colony? I think the Rouxville District was in the Orange River Colony (OFS)
I'm trying to establish where and when he served.
