In February 1916 Lieut.-Colonel G. D. White left to take up a Staff appointment in France, and was succeeded by Lieut.-Colonel G. C. Hamilton, D.S.O. From January 1916 until the end of the war, the Battalion was organised on a nine-company basis in the following manner: the first four companies were composed of recruits who were being trained to feed the Battalions at the front. No. 5 Company consisted of men employed on various duties, and the remaining four companies, six to nine, comprised sick and wounded men from France.
On May 29, 1916, Lieut.-General Sir Francis Lloyd, commanding the London Districts, inspected the Battalion, and expressed himself much pleased with its appearance on parade. General Sir George Higginson also paid a visit to the Battalion that year, and both officers and men much appreciated this attention from a veteran Grenadier, who had fought in the Crimean War. In September a duty, somewhat out of the ordinary routine, was assigned to the Reserve Battalion. During an air raid over London, one of the German Zeppelins was brought down in flames in Essex, and the Battalion was ordered to provide a guard over what was left of it during the two following days. In December Lieut.-Colonel Hamilton was given command of the 4th Battalion in France, and was succeeded by Lieut.-Colonel Lord Francis Montagu-Douglas-Scott, D.S.O.
Nothing of interest occurred until 1918, when, owing to the large numbers of men who joined in consequence of the protected trades being brought under the Military Enlistment Act, a Provisional Battalion was formed at Tadworth. This Battalion, under the command of Lieut.-Colonel Maitland, D.S.O., proceeded to Aldershot four companies strong, leaving behind two companies under Captain Lord Forbes. A month later Lieut.-Colonel Maitland was succeeded by Lieut.-Colonel G. E. C. Rasch. Throughout the war the Reserve Battalion found the public duties in London, and on several occasions provided guards of honour, notably at the funeral of Field-Marshal Earl Roberts at St. Paul's Cathedral on November 19, 1914.
Field training was carried out by one company at a time at Basildon Park, lent by Captain J. A. Morrison, during the autumn of 1914, and at Bovingdon Green Camp, Marlow, during the summer of 1915, and after that at Tadworth Camp. In addition, there were specialist courses: bombing at Southfields and Godstone, Musketry at Rainham and Hythe, Machine Gun courses and Gas Instruction at Chelsea.
The arduous and somewhat thankless task of continually training men as quickly as possible, to feed the battalions in France, was successfully carried on during the four years of the war, and letters from the four Commanding Officers bear ample testimony to the efficiency of the Battalion organisation. The greater part of the work fell on the Commanding Officer, Adjutant, and the senior Captains, whose untiring efforts will ever be gratefully remembered by the regiment. Day in and day out, during four long years, these officers strived to maintain with each draft the high standard of the regiment, and this result could not have been effected without the invaluable assistance of the warrant officers and sergeants.
