The term "British Expeditionary Force" is often used to refer only to the forces present in France prior to the end of the First Battle of Ypres on 22 November 1914. By the end of 1914—after the battles of Mons, Le Cateau, the Aisne and Ypres—the existent BEF had been almost exhausted, although it helped stop the German advance. An alternative endpoint of the BEF was 26 December 1914, when it was divided into the First and Second Armies (a Third, Fourth and Fifth being created later in the war). "British Expeditionary Force" remained the official name of the British armies in France and Flanders throughout the First World War.
