Reformed in 1920 in the Territorial Army (TA) as the 48th (South Midland) Infantry Division, it saw active service in the Second World War with the British Expeditionary Force (BEF) in Belgium and France before being evacuated from Dunkirk to the United Kingdom. It was converted into a training reserve division in December 1942, remaining in the United Kingdom in that status for the rest of the war. Disbanded after the war, the division was not reformed again. In both world wars, the division raised a second line reserve formation; the 61st (2nd South Midland) Division in the First World War, and 61st Division in the Second World War.
