Abstract: The purpose of the work is to clarify and detail the data of historiographical research on the problems of recruitment and material support of the Kostroma militia as one of the militias of the III district.
Among the sources, documents from the collections of the Russian State Military Historical Archive, the Russian State Historical Archive and the State Archive of the Kostroma Region are considered. The documentary data are compared with the texts of the works of K.A. Voensky, V.R. Apukhtin, N.N. Vinogradov and others.
An important component of the information sources, which has not been updated to date in historiography, are the mechanisms of recruitment, staffing, calculation of financing and provision of fodder, as well as instructions on accepting money and military property, accepting donations, resolutions on uniforms and equipment of warriors, issues of armament and training of recruits, as well as supply of the Kostroma militia. The documents allow us to establish the course of the discussion about the figures of giving warriors from noble estates and mechanisms for overcoming contradictions. In addition, the archives contain information about the social and everyday problems of the inhabitants of the province in connection with the events of 1812-1814 and ways to solve them. Special attention is paid to the problem of the coincidence of the time of recruitment and recruitment into the militia in 1812-1813 among the burghers of the Kostroma province.
The results obtained make it possible to clarify the chronology of the formation of the Kostroma province militia, to detail economic and financial indicators, such as: the size of donations, the burden on various estates when donating money and in kind, the size of salaries and one-time allowances for militia members.

Abstract: The article is devoted to the history of the Kostroma militia during the Patriotic War of 1812 and aims to clarify and detail the data of historiographical research on the regimental commanders of the Kostroma militia as one of the militias of the III district. Among the sources, documents from the collections of the Russian State Military Historical Archive, the Russian State Historical Archive and the State Archive of the Kostroma Region are considered. The documentary data are compared with the texts of the works of K.A. Voensky, V.R. Apukhtin, N.N. Vinogradov and others. The service records of the militia leaders are considered in the most detail. Archival materials are presented, which reflect the activities of the militia regiments in the Foreign campaign of 1813–1814. The generalization of biographical information made it possible to assess the military and managerial potential of the Kostroma militia. The analysis of biographical information on personalities, especially those related to military service before the campaigns of 1812–1814, aims to provide a reasoned assessment of both their personal merits and the overall results of the actions of the Kostroma militia. According to the results of the study of biographical information of the leaders of the Kostroma militia of 1812–1814, there are grounds for a number of conclusions. Firstly, the general command and militia regiments were headed by people with serious military experience: participants in the campaigns of the 1780s – 1790s, associates of A.V. Suvorov, participants in the military campaigns of 1805–1807. Secondly, among the commanders of military units there were persons with experience of civilian managers. And finally, it is particularly worth noting the full staffing of the militia regiments: from warrant officers to senior officers. This made it possible to put a man with military training at the head of each militia unit. As a result, the militia had high training and discipline, which was manifested in the Foreign campaign of 1813–1814 and when participating in military operations.
