As a Kannada historian, Banasum published "Banglodaya",[7] a book about the creation of Bangladesh; and "Bharata-Pakistana Samarada Itihasa[8]" History of Indo-Pak War; the books demanded considerable labour and his meetings with the military personnel at various levels culminated in another monumental work on the biographical sketches of one hundred warriors from Karnataka who fought in the Indo-Pakistani War of 1971, some of whom lost their lives in the war. The book "Karnatakada Veera Yodharu[9]" (Kannada: ಕರ್ನಾಟಕದ ವೀರಯೋಧರು) (Brave Warriors of Karnataka), was released in 1972 by General K. M. Cariappa.[10] He also wrote biographies of Sir M.
