By the time 10247 joined The Buffs, Britain had been at war with Germany for nearly three weeks and volunteers throughout Britain had been flocking to recruiting offices. The Buffs did not extend the number series above to men joining its new service battalions. Those volunteers who enlisted for war-time service only, were issued with numbers from a new series which began at 1 and was prefixed with G/. Men who, during the war, continued to enlist under regular 7&5 terms, were issued with numbers in continuation of the series above. Their numbers were prefixed with the letter L/.
Thus, for example, L/10356 joined up for seven years with the colours and five on the reserve, on 13th December 1914. Had he joined up for war-time service only, his number would have been in the high 4000s or low 5000s and would have been prefixed with G/. The Royal Sussex Regiment and The Queen's (Royal West Surrey) Regiment, also adopted the same numbering policy regarding war-time only recruits and those men who wished to forge a career in His Majesty's Army.

Historical records of The Buffs (East Kent Regiment) 3rd Foot 1914-1919
This from The Naval & Military Press:
"During the Great War eight battalions of the regiment went on active service and another seven (including 1st Garrison Battalion) served at home. No less than 32,000 men passed through the ranks of the regiment of whom some 6,000 died; forty-eight battle honours were awarded and one VC.
"Appendices contain separate rolls of honour of officers and other ranks with names grouped alphabetically by ranks; all ranks list of honours and awards and foreign awards, and separate lists of Mention in Despatches. The 1st, 6th, 7th and 8th Battalions served on the Western Front, the 2nd Battalion in Macedonia with 28th Division following ten months in France and Belgium, the 1/4th in India and Aden, 1/5th in India and Mesopotamia and finally the 10th Battalion (formed in Egypt in Feb 1917 from two converted Kent yeomanry regiments) fought in Palestine and on the Western Front with 74th (Yeomanry) Division.
"Apart from one chapter describing the raising of wartime battalions and the initial disposition of the two TF battalions, and one on their affiliated regiment, the Queen's Own Rifles of Canada, the chapters of this history each cover well-defined periods of the war in the various theatres in which the parts played by all battalions involved are recorded. The groundwork or skeleton is based on battalion, brigade or divisional war diaries, fleshed out by personal narratives and diaries provided by men who had fought and survived. Where possible, the names of the officers who became casualties in any action are given in the text after the record of the battle, but only the number in the case of other ranks. Again, wherever possible the recipients of honours (all ranks) have been named in the account as news of their decorations reached their battalion. A good history."
