Ostensibly the journal was written “to beguile the tedium of a camp life, and without the remotest intention of publication,” but a careful study of the text would reveal that the purpose was to draw the attention of the English people to the state of affairs in the northwest frontier and to the possibility of annexing Punjab after the death of the ailing Ranjit Singh. Osborne’s account of the discipline and efficiency of the Sikh army carries the suggestion that it was inferior to the British army, though superior to the forces of other princes of India.
