50th (Northumbrian) Division

The British 50th (Northumbrian) Division was a first-line Territorial Force division. The division was sent to France in April 1915 and served on the Western Front for the duration of the First World War. The division suffered heavily during the Second Battle of the Aisne in May–June 1918 and underwent a reorganisation in July 1918.

For the division's formation and operations in World War II, see British 50th (Northumbrian) Infantry Division.

Formation
Under the Army reforms of 1908, the Territorial Force was formed and organised into regional Divisions, area Brigades and local Battalions. In 1907 Lieutenant General Robert Baden-Powell was appointed to command the Division; he held command from April 1908 to 1910. A Division was in effect a self-contained army of approximately 18,000 men including infantry, cavalry, artillery, engineer, medical, supply and signal units. The Northumberland Division was typical, consisting of three infantry brigades, the 'Northumbrian', 'York and Durham' and 'Durham Light Infantry (DLI)' Brigades. Each brigade was composed of four infantry battalions.
