The campaigns of Nadir Shah's troops in Dagestan are devoted to several specialized studies published in the form of monographs, many articles, the preparation of which involved a wide range of sources and diverse literature. At the same time, it cannot be said that it is exhaustive. Interesting information resources about the events of 1741-43 in Dagestan, still not properly studied, include information from Europeans who visited the region in the 30s-40s of the XVIII century. Among those who left written evidence, the Englishman Jonas Hanway and the Frenchman Louis Bazin, who were well acquainted with each other. The first of them published a four-volume collection "Historical account of British trade through the Caspian sea" (London, 1753). The fourth volume contains interesting information about the campaign of Nadir Shah. The events of 1741-43 in Dagestan are described in Chapter XXIX, parts of which are translated from English in this article. The second of them in his letter, written in 1751, describes the events, which he witnessed, because he was in Derbent at the time of arrival there Nadir Shah. The article contains a translation of a passage of a letter from the French language, published in "Instructive and curious letters" (Paris, 1780). The analysis of narratives showed that Bazin's stories served as the main source for Hanway. At the same time he had messages from Europeans who were in the Russian and Persian service, from the Russian military and government officials and, possibly, Persian subjects, which allowed him to make a more informative message.
