The marquis de La Chétardie was the first French envoy to Russia invested with the title of ambassador. This honor, denied to Peter the Great, was accorded to his niece Anna, although the two countries were then on the waning of their first armed conflict. La Chétardie’s mission in St. Petersburg revealed both his qualities and weaknesses. A polished, experienced courtier, an expert conversationalist at home in fashionable gatherings and punctilious about court ceremonial, he failed at every project he undertook. Nevertheless, some of these failures were not his alone. Having played a minor role in the coup d’état that put Elisabeth on the throne, he acquired a favor from which he was unable to profit for long. He miscalculated the resources of Russian and Swedish belligerents. Several blunders connected to the exacerbated xenophobia of the Russians, although less his responsibility than his government’s, made him a pariah. Having been denied the role of mediator promised by the sovereign during the ongoing conflict, he was obliged to request his recall. Upon returning to France, he developed a project for an alliance among France, Russia, and Sweden that would have replaced the system of « barriers, » sacrificed Poland, and overturned the prevailing diplomatic system. His second mission was unhappy and brief as a result of his conflict with the Vice-Chancellor Bestoutchef, a conflict that could only end in the fall of one of them. It was La Chétardie who was removed because of his overconfidence in the security of his codes. Thus did the first French embassy to Russia end in confusion. Despite his seductive appeal, La Chétardie had failed in his mission and grand projects.
