After the war there was considerable retrenchment. In the 1920s the RAOC's principal depots were Bramley (ammunition), Chilwell (general and surplus stores), Hereford (ammunition), Pimlico (clothing), Woolwich (gun stores and ammunition) and Weedon (small arms). In 1922 the RAOC headquarters, regimental depot and School of Instruction moved from Woolwich to Hilsea Barracks on the edge of Portsmouth. (The School provided education and training in all aspects of the Corps' work, with the exception of ammunition which was taught at Bramley, where the Army School of Ammunition was opened that same year.) The Royal Army Clothing Depot, Pimlico, closed in 1932 and its stock was mostly transferred to Didcot.
