"Viva Os Boers" by O J O Ferreira records that Wessels (Policeman, age 36),was interned at Caldas da Rainha together with his wife , 1 son and 6 daughters. A second son named Jan Harm Caldas Wessels was born in Portugal, but died on 10 Feb 1902. No mention is made of Wessels being on Kruger's Bodyguard.
8 members of the Bodyguard (indicated as such on the PoW Register) were taken Prisoner in Pretoria on 9 August 1900, so Wessels and his family must have left Pretoria at an early stage and crossed the border into Mozambique late in September 1900
The bodyguard were all ZARP's, as was Wessels. Also : the Medal Advisory Board accepted the service details on his Vorm "B" so there cannot be any doubts about it. I just commented on the data supplied by Ferreira
