Reformed during the Second World War as the 36th Infantry Brigade on 7 October 1939, this time as part of the Territorial Army, and attached to the 12th (Eastern) Infantry Division, duplicate of the 44th (Home Counties) Infantry Division. The brigade was formed as a 2nd Line duplicate of the 132nd (Kent) Infantry Brigade. It fought in the Battle of France in May 1940 where it was overrun by the German Army and dispersed and suffered very heavy casualties, due mainly to the division having none of its support units and the infantrymen having had little training. Reformed in the United Kingdom, it was redesignated 36th Independent Infantry Brigade from 22 June 1940, when the 12th Division was disbanded, until 22 June 1942 when it was assigned to the 78th "Battleaxe" Infantry Division and served in the North African Campaign, in Operation Husky and the Italian Campaign, in particular the Battle of Monte Cassino and later Gothic Line, followed by the Spring 1945 offensive in Italy.
