201st (2/1st Middlesex) Brigade

The 2nd Middlesex Brigade was a 2nd Line Territorial Force Brigade of the British Army in World War I. The brigade was formed as a duplicate of the Middlesex Brigade in October 1914 as part of the 2nd Home Counties Division. As the name suggests, the brigade recruited in Middlesex. In August 1915, in common with all Territorial Force brigades, it was numbered as 201st (2/1st Middlesex) Brigade. Between September 1917 and the end of the year, the brigade was extensively reorganized and lost its territorial identity; henceforth it was known as 201st Brigade.

History
In accordance with the Territorial and Reserve Forces Act 1907 (7 Edw.7, c.9) which brought the Territorial Force into being, the TF was intended to be a home defence force for service during wartime and members could not be compelled to serve outside the country. However, on the outbreak of war on 4 August 1914, many members volunteered for Imperial Service. Therefore, TF units were split into 1st Line (liable for overseas service) and 2nd Line (home service for those unable or unwilling to serve overseas) units. 2nd Line units performed the home defence role, although in fact most of these were also posted abroad in due course.

The Brigade served on home defence duties throughout the war, whilst recruiting, training and supplying drafts to overseas units and formations. It was twice warned to prepare to be transferred to Ireland, and in April 1917 for service on the Western Front, but in the event never left England. It was eventually disbanded in March 1919.
