23rd Brigade Royal Field Artillery
XXIII Brigade, Royal Field Artillery was a brigade of the Royal Field Artillery which served in the First World War.
It was originally formed with 107th, 108th and 109th Batteries, and attached to 3rd Division. In August 1914 it mobilised and was sent to the Continent with the British Expeditionary Force, where it saw service with 3rd Division until 1917. 109th Battery left the brigade in mid-1916 to join CCLXXXI Brigade in 56th Division.
In 1917 it was withdrawn from 3rd Division, to operate under higher unit control, and served out the rest of the war in this role.
