When Volunteer Infantry Brigades were introduced in 1888, the Volunteer Battalions of the Sherwood Foresters formed part of the North Midland Brigade, although from 1901 to 1906 they formed a separate Sherwood Foresters Brigade. When the Volunteer Force was subsumed into the new Territorial Force under the Haldane Reforms in 1908, a new Nottinghamshire and Derbyshire Brigade was formed, as part of the North Midland Division. The brigade was composed of four Volunteer battalions of the Sherwood Foresters: the 5th, 6th, 7th and 8th.
First World War
inspected the division on 19 February 1915, shortly before its departure for France, and gave permission for the Notts & Derby Brigade to change its title to Sherwood Foresters Brigade. In May, when the TF formations were numbered, the brigade became 139th Brigade in the 46th Division. The brigade saw service with the 46th Division throughout the Great War in the trenches of the Western Front from 1915 to 1918.
Disbanded after the war in 1919, the brigade was reformed as the 139th Infantry Brigade in the Territorial Army and again assigned to the 46th Division. However, in 1936 the division was disbanded and its HQ was redesignated 2nd Anti-Aircraft Division. The 6th and 7th Sherwood Foresters were both transferred to the Royal Engineers and converted into anti-aircraft searchlight battalions. The 5th and 8th Sherwood Foresters were both transferred to the 49th Infantry Division. With all of its battalions posted away, the 139th Infantry Brigade was disbanded.
The brigade number was reactivated again when the Territorial Army was doubled in size in spring and summer 1939, in order to meet the threat of Nazi Germany. The 139th Infantry Brigade, formed as a 2nd Line duplicate of 148th Infantry Brigade, was assigned to the 46th Infantry Division, which itself was formed as a duplicate of the 49th Division. The brigade saw service with the 46th Division throughout the Second World War, which began in September 1939. Sent to France with the rest of 46th Division in April 1940 to join the British Expeditionary Force, the brigade was both poorly equipped and trained and lacked any of their signals, artillery, engineer or other support units. The division was sent, along with the 12th and 23rd divisions, to complete their training and to help construct defences and airfields. As a result, the division was battered when facing the German Army's blitzkrieg during the Battle of France in May 1940 and was forced to retreat to Dunkirk had to be evacuated to England. s supporting infantrymen of the 2/5th Battalion, Leicestershire Regiment, 46th Division, near Coldazzo on the Gothic Line, 30 August 1944. After being evacuated, the brigade and division spent the next few years on home defence and training to repel an expected German invasion which never arrived. In late 1942 the 46th Division was sent to North Africa where it became part of British First Army and saw action in the final stages of the Tunisia Campaign. The division did not see service in Sicily but landed at Salerno in September 1943 as part of the US Fifth Army during the initial invasion of Italy. The brigade saw service in Italy until late 1944, transferring to Greece to help calm the Greek Civil War, and returning to Italy in April 1945 for the final offensive, but did not take part in any actual fighting.
