The history of the 1st Cavalry Division
Part of the original British Expeditionary Force, the division went to France in August 1914. Originally titled as the Cavalry Division, it was renamed as1st Cavalry Division on 16 September 1914 when a second division was formed. It remained on the Western Front in France and Flanders throughout the war. The division took part in most of the major actions where cavalry was used as a mounted mobile force, and also many others where the troops were dismounted and effectively served as infantry, including:
1914
