War Office and predecessors: Secretary-at-War, Secretary of State for War, and Commander-in-Chief, In-letters and Miscellaneous Papers

Papers of the Secretary-at-War and the Secretary of State for War are arranged under the various military stations or public departments from which they were sent, or under the subjects with which they deal, or alphabetically by the name of the writer.

The War Office In-Letter books have been arranged in three main groups for listing pursposes. The first includes all the books of original dispatches from various commanders, the second consists of the correspondence received from other government departments, and the third of correspondence from other correspondents, arranged roughly by the alphabetical order of the surnames of the senders. This third group will be found however to include also certain correspondence which might be expected to be found in the volumes of the first two groups. It has been divided into two series - the first consisting of foolscap volumes, the second of smaller volumes.
