Yes, in fact there are three versions about this, there's your version, Col de Kock's version and Mr Ras' version.  The one being that Roelf Venter placed those things after ...(indistinct) and arrived after three hours, Col de Kock's version, that he obtained these from the office, Piet Retief, from W/O Pienaar and Mr Ras says that he had it.  Do you know which version is the truth here?
