151st (Durham Light Infantry) Brigade

The Durham Light Infantry Brigade was formed in 1902 to command the part-time Volunteer battalions of the Durham Light Infantry (DLI). Previously these had been in a combined Tyne and Tees Brigade with battalions of the Northumberland Fusiliers. It consisted of the 1st–4th Volunteer Battalions of the DLI (the 5th VB had remained in the Tyne Brigade), which were renumbered as the 5th–8th Battalions when the Volunteers were subsumed into the Territorial Force (TF) under the Haldane Reforms of 1908. Consisting of 6th–9th Battalions (the 5th Bn joined the York and Durham Brigade), it became part of the TF's Northumbrian Division. During World War I it was numbered as the 151st (Durham Light Infantry) Brigade on 14 May 1915, when the division became the 50th (Northumbrian) Division. The TF also raised 2nd Line units and formations, and the 190th (2nd Durham Light Infantry) Brigade was formed in 63rd (2nd Northumbrian) Division. The 1st Line battalions adopted the prefix '1/'
