staff and activities moved to Lydd where they formed the Siege Artillery branch of the School of Gunnery; Shoeburyness continued to provide training in Field, Horse, Mountain and Garrison Artillery. In 1915, the Field Artillery and Horse Artillery elements from Shoeburyness were transferred to Larkhill (where over of land had been acquired in 1897 for use as firing ranges). Chapperton Down Artillery School was established in 1916, to the west of Larkhill, to train French battery commanders; the following year it expanded to run courses for the Home Defence Artillery. Also in 1916 a Training Centre for Heavy Artillery was established, at Woolwich; the following year it moved to Winchester. In December 1919, the Army Council decided to combine the School of Instruction for Royal Horse and Field Artillery with the Chapperton Down Artillery School and the Heavy Artillery Training Centre to form an expanded School of Artillery. This took place in 1920; the following year the Siege Artillery School moved to Larkhill from Lydd and was likewise merged into the School. Shoeburyness, though, retained the Coast Artillery School of the Royal Garrison Artillery; in 1940 it moved to Great Orme near Llandudno, where it stayed for the duration of the war, before moving again to the Royal Citadel, Plymouth (where it remained until 1956, when the UK's coastal artillery network was disbanded). Operations The School provides Phase 2 training for recruits to the Royal Artillery: this training includes gunnery, air defence, surveillance and signals. Trained officers and gunners are then posted to units worldwide, but return to the School for frequent refresher courses. The School is also the home of the Gunnery Training Team, which provides a training consultancy service to the Royal Artillery and the wider Army. Facilities Facilities which have grown up around the school include the Royal Artillery Barracks which accommodates 14 Regiment Royal Artillery and Roberts Barracks, named after Field Marshal Lord Roberts, which accommodates 32 Regiment Royal Artillery as well as Horne Barracks, named after General Lord Horne, which accommodates 47 Regiment Royal Artillery. The Officers' Mess and Quarters, designed by William A Ross, Chief Architect to the War Office, and built between 1936 and 1941 is a Grade II listed building.
