 Cartier left for France in early June 1542, encountering Roberval and his ships along the Newfoundland coast, at about the time Roberval marooned Marguerite de La Rocque.Despite Roberval's insistence that he accompany him back to Saguenay, Cartier slipped off under the cover of darkness and continued on to France, still convinced his vessels contained a wealth of gold and diamonds.He arrived there in October, in what proved to be his last voyage.
