Some of Bergh's earliest work at the Cape included leading bartering trips to the neighboring as well as to the more remote kraals such as those of the Hessequas, a Khoi tribe, in search of livestock and in particular cattle.
[4] In addition to these, one of the earliest accounts of Bergh's expeditions included leading a small party of colonists assembled to recapture and return to the Colony three men, who had escaped a few days earlier, which he did.
In 1682, shortly before his scheduled trip to Vigiti Magna, Bergh was despatched instructed to investigate and retrieve any surviving treasures from the stranded English ship Johanna,[5] which had was wrecked near Cape Agulhas on 8 June 1682.
[6][7] During this expedition, Bergh and two other members of his group inscribed their names on the face of a rock near the site of a spring[8] (later to become known as "Berghfontein", and designated as a former South African National Monument) as well as discovered and spent the night in a large cave (later to become known as "Heerenlogement", and which was used subsequently by numerous later explorers, including Van Der Stel himself).
[9] As a result of his experience in 1682, van der Stel again chose Bergh to lead another expedition in 1683 to the Namaquas, the people from the North who came to trade copper ore at the Castle.
In July 1686 Bergh was once again despatched in the direction of Cape Agulhas to search for the wreck of the Portuguese ship, Nostra Signora de los Milagnos, which had run aground and been abandoned and which Company officers had subsequently purchased.
Bergh chose the former and left for Ceylon shortly thereafter on 29 December 1690 (without his wife) on the ship Pampus,[12] where he remained for five years until 1695 before being allowed to return to the Cape, once the scandal of his previous conviction had dissipated amidst the Burghers.
Soon after his return the Cape, it appears Bergh's previous conviction was not held against him and he was appointed Captain of the Garrison by the Governor and took up residence in a grand home on the Heerengracht (currently Adderleystraat) next to the church.
In addition to his home on the Heerengracht, Bergh was also the first owner of the farm De Hoop, located close to the town (on the site of present day Gardens), the remaining buildings of which still exist today and are operated as historic luxury accommodation[15] as well as two bungalows in Piquetberg.
