SAFF for that period shows Pte. Stewart, S (Killed), Fisher J.P. (Killed), Rensburg, P (Sl.Wd) and Muller H (sl.Wd) at Oudtshoorn on 17/9/01. As they were members of the CDF, I assume the action took place in the Cape. There was a series of actions around Oudtshoorn in Sept.1901 during the pursuit of Theron. Suggest a study of Maurice Vol.4 pages 283-284 and deeper research might reveal more.
Maurice relates a series of actions in and about the mentioned area during the pursuit of Theron's commando in September 01. Maurice also mentions that a certain Lt/Col. Burke was "in command of the local troops in this district" - which lends support to any supposition that local CDF lads were on duty (or even part of) the main British columns.
