The ready response to this appeal soon supplied more than sufficient men for the first six divisions of the New Army, eventually numbered 9 to 14. New battalions continued to be raised to absorb as far as possible the stream of recruits and on the 11th of September the formation of six additional divisions—the 15th to the 20th—was authorised. Thus the 20th (Light) Division came into existence. It was to be composed entirely of Rifle and Light Infantry battalions—formed into the 59th, 60th, and 61st Infantry Brigades—and Divisional troops. A few changes were made later, and the order of battle of the Division as finally constituted was as follows:—
59th Infantry Brigade
10th (Service) Battalion the King’s Royal Rifle Corps.
11th (Service) Battalion the King’s Royal Rifle Corps.
10th (Service) Battalion the Rifle Brigade.
11th (Service) Battalion the Rifle Brigade.
60th Infantry Brigade
6th (Service) Battalion the Oxfordshire and Buckinghamshire Light Infantry.
6th (Service) Battalion the King’s (Shropshire Light Infantry).
12th (Service) Battalion the King’s Royal Rifle Corps.
