context_page_description: The British Army during World War I fought the largest and most costly war in its long history. Unlike the French and German Armies, the British Army was made up exclusively of volunteers—as opposed to conscripts—at the beginning of the conflict. Furthermore, the British Army was considerably smaller than its French and German counterparts.
  During World War I, there were four distinct British armies. The first comprised approximately 247,000 soldiers of the regular army, over half of which were posted overseas to garrison the British Empire, supported by some 210,000 reserves and a potential 60,000 additional reserves. This component formed the backbone of the British Expeditionary Force, which was formed for service in France and became known as the Old Contemptibles. The second army was provided by the approximately 246,000-strong Territorial Force, initially allocated to home defence but used to reinforce the BEF after the regular army suffered heavy losses in the opening battles of the war. The third army was Kitchener's Army, comprising men who answered Lord Kitchener's call for volunteers in 1914–1915 and which went into action at the Battle of the Somme in 1916.
context_section_description: In August 1914, there were 28,060 officers in the British Army, of which 12,738 were regular officers, the rest were in the reserves. The number of officers in the army had increased to 164,255 by November 1918. These were survivors among the 247,061 officers who had been granted a commission during the war.
  Most pre-war officers came from families with military connections, the gentry or the peerage; a public school education was almost essential. In 1913, about 2% of regular officers had been promoted from the ranks. The officer corps, during the war, consisted of regular officers from the peacetime army, officers who had been granted permanent commissions during the war, officers who had been granted temporary commissions for the duration of the war, territorial army officers commissioned during peacetime, officers commissioned from the ranks of the pre-war regular and territorial army and temporary officers commissioned from the ranks for the duration of the war alone.
  In September 1914, Lord Kitchener announced that he was looking for volunteers and regular NCOs to provide officers for the expanding army. Most of the volunteers came from the middle class, with the largest group from commercial and clerical occupations (27%), followed by teachers and students (18%) and professional men (15%). In March 1915, it was discovered that 12,290 men serving in the ranks had been members of a university or public school Officers' Training Corps (OTC). Most applied for and were granted commissions, while others who did not apply were also commissioned. Direct commissioning largely ceased early in 1916, from then most new officers had served in the ranks first, even if in a unit of potential officers.
  Once a candidate was selected as an officer, promotion could be rapid. A. S. Smeltzer was commissioned as a Second Lieutenant in 1915, after serving in the Regular Army for 15 years. He rose in rank, and by the Spring of 1917 had been promoted to Lieutenant Colonel and was commanding officer of the 6th Battalion, The Buffs (Royal East Kent Regiment).
  Along with rapid promotion, the war also noticeably lowered the age of battalion commanding officers. In 1914, they were aged over 50, while the average age for a battalion commanding officer in the BEF between 1917 and 1918 was 28. By this stage, it was official policy that men over 35 were no longer eligible to command battalions. This trend was reflected amongst the junior officers. Anthony Eden was the Adjutant of a battalion when aged 18, and served as the Brigade Major in the 198th Brigade while still only aged 20.
  The war also provided opportunities for advancement onto the General Staff, especially in the early days, when many former senior officers were recalled from retirement. Some of these were found wanting, due to their advanced age, their unwillingness to serve, or a lack of competence and fitness; most were sent back into retirement before the first year of the war was over, leaving a gap that had to be filled by lower-ranking officers. Criticism of the quality of staff work in the Crimean War and the Second Boer War had led to sweeping changes under Haldane. The Staff College, Camberley was greatly expanded and Lord Kitchener established another staff college at Quetta for Indian Army officers in 1904. Nonetheless, when war broke out in August 1914, there were barely enough graduates to staff the BEF. Four-month-long staff courses were introduced, and filled with regimental officers who, upon completing their training, were posted to various headquarters. As a result, staff work was again poor, until training and experience slowly remedied the situation. In 1918, staff officers who had been trained exclusively for static trench warfare were forced to adapt to the demands of semi-open warfare.
  During the course of the war, 78 British and Dominion officers of the rank of Brigadier-General and above were killed or died during active service, while another 146 were wounded, gassed, or captured.
