The 18th Infantry Division was an infantry division of the British Army which fought briefly in the Malayan Campaign of the Second World War. In March 1939, after the re-emergence of Germany as a European power and its occupation of Czechoslovakia, the British Army increased the number of divisions in the Territorial Army (TA) by duplicating existing units. The 18th Infantry Division was formed in September 1939 as a second-line duplicate of the 54th (East Anglian) Infantry Division, with men from Essex and the East Anglian counties of Norfolk, Suffolk and Cambridgeshire.
