The British Expeditionary Force (BEF) was the six-divisions the British Army sent to the Western Front during the First World War. Planning for a British Expeditionary Force began with the 1906–1912 Haldane reforms of the British Army carried out by the Secretary of State for War Richard Haldane following the Second Boer War (1899–1902).
Field Marshal John Denton Pinkstone French, 1st Earl of Ypres,, known as Sir John French from 1901 to 1916, and as The Viscount French between 1916 and 1922, was a senior British Army officer. Born in Kent to an Anglo-Irish family, he saw brief service as a midshipman in the Royal Navy, before becoming a cavalry officer. He achieved rapid promotion and distinguished himself on the Gordon Relief Expedition. French had a considerable reputation as a womaniser throughout his life, and his career nearly ended when he was cited in the divorce of a brother officer while in India in the early 1890s.
I Corps was an army corps in existence as an active formation in the British Army for most of the 80 years from its creation in the First World War until the end of the Cold War, longer than any other corps. It had a short-lived precursor during the Waterloo Campaign.
Sir Ian Standish Monteith Hamilton, was a British Army general who had an extensive British Imperial military career in the Victorian and Edwardian eras. Hamilton was twice recommended for the Victoria Cross, but on the first occasion was considered too young, and on the second too senior. He was wounded in action at the Battle of Majuba during the First Boer War, which rendered his left hand permanently injured. Near the end of his career, he commanded the Mediterranean Expeditionary Force in the Gallipoli Campaign of the First World War.
The Mediterranean Expeditionary Force (MEF) was the part of the British Army during World War I that commanded all Allied forces at Gallipoli and Salonika. It was formed in March 1915, under the command of General Sir Ian Hamilton, at the beginning of the Gallipoli campaign of the First World War.
General Sir Horace Lockwood Smith-Dorrien, was a British Army General. One of the few British survivors of the Battle of Isandlwana as a young officer, he also distinguished himself in the Second Boer War.
The Territorial Force was a part-time volunteer component of the British Army, created in 1908 to augment British land forces without resorting to conscription. The new organisation consolidated the 19th-century Volunteer Force and yeomanry into a unified auxiliary, commanded by the War Office and administered by local County Territorial Associations. The Territorial Force was designed to reinforce the regular army in expeditionary operations abroad, but because of political opposition it was assigned to home defence. Members were liable for service anywhere in the UK and could not be compelled to serve overseas. In the first two months of the First World War, territorials volunteered for foreign service in significant numbers, allowing territorial units to be deployed abroad. They saw their first action on the Western Front during the initial German offensive of 1914, and the force filled the gap between the near destruction of the regular army that year and the arrival of the New Army in 1915. Territorial units were deployed to Gallipoli in 1915 and, following the failure of that campaign, provided the bulk of the British contribution to allied forces in the Sinai and Palestine Campaign. By the war's end, the Territorial Force had fielded twenty-three infantry divisions and two mounted divisions on foreign soil. It was demobilised after the war and reconstituted in 1921 as the Territorial Army.
IV Corps was a corps-sized formation of the British Army, formed in both the First World War and the Second World War. During the First World War the corps served on the Western Front throughout its existence. During the Second World War it served in Norway and Britain until it was transferred to India, which was threatened with attack after Japan entered the war.
Field Marshal William Edmund Ironside, 1st Baron Ironside, was a senior officer of the British Army who served as Chief of the Imperial General Staff during the first year of the Second World War.
The II Corps was an army corps of the British Army formed in both the First World War and the Second World War. There had also been a short-lived II Corps during the Waterloo Campaign.
The Reserve Army was a field army of the British Army and part of the British Expeditionary Force during the First World War. On 1 April 1916, Lieutenant-General Sir Hubert Gough was moved from the command of I Corps and took over the Reserve Corps, which in June before the Battle of the Somme, was expanded and renamed Reserve Army. The army fought on the northern flank of the Fourth Army during the battle and became the Fifth Army on 30 October.
The Allies of World War I, Entente Powers, or Allied Powers were a coalition of countries led by the United Kingdom, France, Russia, Italy, Japan, and the United States against the Central Powers of Germany, Austria-Hungary, the Ottoman Empire, Bulgaria, and their colonies during the First World War (1914–1918).
General Sir Archibald James Murray, was a British Army officer who served in the Second Boer War and the First World War. He was Chief of Staff to the British Expeditionary Force (BEF) in August 1914 but appears to have suffered a physical breakdown in the retreat from Mons, and was required to step down from that position in January 1915. After serving as Deputy Chief of the Imperial General Staff for much of 1915, he was briefly Chief of the Imperial General Staff from September to December 1915. He was subsequently Commander-in-Chief of the Egyptian Expeditionary Force from January 1916 to June 1917, in which role he laid the military foundation for the defeat and destruction of the Ottoman Empire in the Arabian Peninsula and the Levant.

He played an important role in the war, leading the 4th Division in the retreat of August 1914, and commanding VII Corps at the unsuccessful diversion of the Attack on the Gommecourt Salient on the first day on the Somme and at the Battle of Cambrai in November 1917.

In the campaign that followed, he commanded the 5th Field Company, before going on to lead the 8th Field Company and the 4th Pioneer Battalion on the Western Front.
