The chargé d'affaires also carried out correspondence with several other diplomatic missions in the Mediterranean and Europe and was specifically tasked with maintaining the neutrality of the port of Malta and the Order of Saint John with European powers. The correspondence is now housed in 33 boxes with each box organized by city. The letters are primarily in French, but also include Spanish, Italian, Arabic, Turkish, Greek and other Mediterranean languages. One can find both official and personal correspondence in the collection, including a broad range of topics from the political affairs of France, the Ottoman Empire, and North Africa, to details about shipping, trade, slavery, and the Order of Saint John of Jerusalem. Related records can be found in the Archives diplomatiques, Archives nationales of France, and Series 9, Correspondence of the Archives of the Order of Malta at the National Library of Malta.
