of CCXCVI (2/II NM) Bde; D (H) Bty became D (H) Bty in CCXCVIII Bde. Interwar When the TF was reformed in 1920 (and renamed as the Territorial Army (TA)), RFA brigades standardised on an establishment of three field and one howitzer battery: the 3rd and 4th North Midland Bdes were combined into a single unit consisting of two Derbyshire batteries from the 4th and two Staffordshire batteries from the 3rd. Although the unit was briefly referred to as the 3rd North Midland Bde, its HQ was at Siddal's Road, Derby, and continued the lineage of the old 4th; it remained part of 46th (North Midland) Division. In 1921 it was redesignated as 62nd (North Midland) Brigade, RFA with the following organisation: 245 (Derby) Bty 246 (Derby) Bty (Howitzers) 247 (Wolverhampton) Bty 248 (West Bromwich) Bty The unit title became 'Field Brigade, RA', in 1924 when the RFA was subsumed into the Royal Artillery. In 1938 the RA adopted the designation 'regiment' instead of 'brigade' for a lieutenant-colonel's command. In the 1920 reorganisation, 6th Staffordshire Bty at Stafford was briefly redesignated 4th Staffordshire in 2nd North Midland Bde, then from 1921 as 244 (Stafford) Bty in 61st (North Midlaned) Field Bde. Just before the outbreak of World War II it transferred to 61st's duplicate, 116th (North Midland) Field Regiment. Anti-aircraft conversion During the 1930s the increasing need for anti-aircraft (AA) defence for Britain's cities was addressed by converting a number of TA units and formations to the AA role. 46th (North Midland) Division became 2nd AA Division in 1936 and many of its infantry battalions were subsequently converted to AA gun or searchlight roles. By the end of 1937, 62nd Field Brigade was also being converted. During 1938, Regimental HQ (RHQ) and the two Derby batteries reorganised as 68th (North Midland) AA Regiment, while the two Staffordshire batteries from the old 3rd North Midland left to form the basis of a new 73rd AA Regiment at Wolverhampton. Memorials There are two memorials to the 46th (North Midland) Division on the battlefield of the Hohenzollern Redoubt: one on the road between Vermelles and Hulluch, marking the jumping-off point of the attack, and one on the site of the redoubt itself, which lists all the units of the division.
