British Expeditionary Force order of battle (1914)

The British Expeditionary Force order of battle 1914, as originally despatched to France in August and September 1914, at the beginning of World War I. The British Army prior to World War I traced its origins to the increasing demands of imperial expansion together with inefficiencies highlighted during the Crimean War, which led to the Cardwell and Childers Reforms of the late 19th century. These gave the British Army its modern shape, and defined its regimental system. The Haldane Reforms of 1907 formally created an Expeditionary force and the Territorial Force.

The British Army was different from the French and German Armies at the beginning of the conflict in that it was made up of professional soldiers who had volunteered, rather than conscripts.^[1] It was also considerably smaller than its French and German counterparts.^[2]

The outbreak of the First World War in August 1914 saw the bulk of the changes in the Haldane reforms put to the test. The British Expeditionary Force (BEF) of six divisions was quickly sent to the Continent.^[3]

This order of battle includes all combat units, including engineer and artillery units, but not medical, supply and signal units. Commanders are listed for all formations of brigade size or higher, and for significant staff positions.
