The collection consists of correspondence, manuscripts, personal documents, subject files and printed materials. Almost half the correspondence is from Varvara (Vali︠a︡) Shakhovskai︠a︡, his wife, from whom he was divorced in 1932 but whose friendship he enjoyed until his death in 1961. A large portion of the manuscripts is in the form of a diary which, for the years 1919-1920, relates the activities of the Cuirassiers during the Civil War. The subject files deal exclusively with the Cuirassier Regiment and its veterans' organization in emigration. They include minutes, official mailings, regiment songs and poems and copies of the regiment publication, "Vestnik," for the period 1928-1931.
