The 5th Division was a permanently established Regular Army division that was amongst the first to be sent to France as part of the original British Expeditionary Force (BEF) at the outbreak of the First World War. It served on the Western Front for most of the war except for a brief period on the Italian Front from 27 November 1917 to 1 April 1918. The 5th Division, as a Regular Army formation (one of the Old Contemptibles) fought in many of the major battles of the Western Front from the Battle of Mons in 1914, the later stages of the Somme offensive, including the first battle using tanks, up to the Battle of the Selle in 1918.
