 With the rest of the division, the brigade was stationed in Cornwall on home defence, anticipating a possible German invasion which, fortunately, never arrived due to the attempt to gain air superiority which failed during the Battle of Britain.In late December 1942 the division and brigade were reduced to a Lower Establishment and became a training formation in the United Kingdom.However, 7 November 1943, the 145th Brigade HQ was disbanded, and its component units were transferred elsewhere.
