The history of this failed expedition is well charted by historians, and Barrallier's frequently disparaging assessments of Gogy as 'useless' have been echoed by some historians who perceived both his disturbingly violent treatment of his wife, who accompanied the expedition, and his seemingly mercurial behaviour as 'obnoxious' and troublesome.
(16) This detailed local and cultural knowledge must have been explained to Barrallier by Gogy, as the only other Aboriginal people in the party at this stage of the expedition were Gogy's wife, whom Barrallier infrequently mentions, and his young son Gogy.
(18) These parallels between Gogy and Bennelong, which I will tease out in this paper, suggest that Gogy's actions were likewise performative and strategic.
However, unlike Phillip, who eventually became partially aware of Bennelong's strategic endeavours throughout the course of their friendship (spanning a number of years and including Bennelong's journey back to Britain with the governor at the end of his commission in 1792), (19) Barrallier knew Gogy for less than two months, so remained oblivious to the motives behind Gogy's confusing actions.
(20) Gogy's contemporary, Boongaree, from Broken Bay who moved to Port Jackson for instance, circumnavigated Australia with Matthew Flinders on the HMS Investigator from 1801 to 1803 encountering various Aboriginal strangers speaking foreign tongues.
As we have seen, Gogy quickly attached himself to Barrallier, and he arguably found this to be a privileged position that he alone wanted to occupy and so jealously guarded.
It seems that in response Gogy attempted to insinuate himself back into Barrallier's favour.
Towards the end of the expedition, Gogy seemed especially determined to show Barrallier that his allegiance was to the French surveyor and not the Gandangara 'natives'.
Yet Gogy's attempts to forge an alliance with Barrallier seemed to fall on deaf ears, as Barrallier instead attributed these actions to his guide's obsequiousness.
Gogy's motive for fostering a close alliance with Barrallier, not to mention the four redcoats who accompanied the expedition, became apparent during one of their excursions from the depot into the mountains.
As a result, Gogy appeared to have changed tactic, and thereafter attempted to prevent Barrallier from having further contact with Goondel and his men.
Gogy's most notorious and perplexing performance was a violent assault on his wife.
