 The regiment did not mechanise before the outbreak of the Second World War, and continued to train for service as horsed cavalry.In early 1939, it was authorised by the War Office to recruit up to its full wartime establishment, and with a heavy drive this was reached in May, with a headquarters squadron and three sabre squadrons.As part of the Cavalry Corps, which by now consisted almost entirely of Yeomanry units, it was assigned a wartime role as part of the 6th Cavalry Brigade in the 1st Cavalry Division.
