The Branch did not obtain a permanent home until October 1919; thus a large amount of important material did not become available until it was unpacked and sorted after this date, and it was then found necessary to re-write an account of the initial operations already partly drafted.
The British Expeditionary Force in France in 1914 was not acting independently, and formed only a small part of the Allied Armies engaged; it has therefore been necessary to include an account of the action of the French and Belgian forces sufficient to provide a proper framework for the British operations.
