Bradstreet continued westward. He did not know yet that his unauthorized diplomacy was angering his superiors. He reached Fort Detroit on August 26, where he negotiated another treaty. In an attempt to discredit Pontiac, who was not present, Bradstreet chopped up a peace belt the Ottawa leader had sent to the meeting. According to historian Richard White, "such an act, roughly equivalent to a European ambassador's urinating on a proposed treaty, had shocked and offended the gathered Indians." Bradstreet also claimed that the Native Americans had accepted British sovereignty as a result of his negotiations, but Johnson believed that this had not been fully explained to the Native Americans and that further councils would be needed. Although Bradstreet had successfully reinforced and reoccupied British forts in the region, his diplomacy proved to be controversial and inconclusive.
