The 20th (Light) Division was authorised on 11 September 1914 and was to be composed of newly raised battalions from quick marching rifle and light infantry regiments. The 59th and 60th Brigades were concentrated at Blackdown with the Division Headquarters and other division troops. The 61st Brigade was concentrated at Aldershot, where the medical component also trained, the Artillery was formed near Deepcut, the engineers were trained at Chatham. Clothing, in the form of emergency "Kitchener Blue" uniforms did not arrive until November, together with a few old rifles for drill practice, the artillery had only two 90 mm guns and two 15-pounders per brigade. The supply situation had improved by February 1915 when the Division moved to Whitley, by which time the 11th DLI, which had a large number of miners in it had become the Division pioneer battalion, trading places in the 61st Brigade with the 12th King's Regiment, the original divisional troops battalion. In April the Division marched to Salisbury Plain to complete its training and were joined by the field ambulances after their training in June. the Division was inspected by the King at the end of that month, and embarked for France in the later part of July.
