up in Botswana, he spoke Tswana fluently and all of the askaris and people that worked with him was people that were clued up with the Botswana set-up of the African National Congress.   Then there was another group under W/O Paul Van Dyk who was mainly Eastern Transvaal, because he worked Swaziland for quite few years, I think five years and mostly people, ANC cadres or askaris who infiltrated and knew the Swaziland set-up very well.   In the same way I operated in another region and there was a fourth group, so when talking about Koos Vermeulen was working from his base, when not needed as a whole party, as a whole Vlakplaas group in one specific area like for instance in November 1981 with the Mningi killings in Durban.
