Recruiting had continued at a great speed during the months of July, August and September, and the training companies had assumed such unmanageable proportions that they were subdivided and a new training company, C, under Major H. J. Duncan-Teape, was formed, the Expeditionary Company being renamed D.

On the 29th August 1915 the Battalion was visited by the following ex-officers of the Regiment:

On this occasion Church Parade was held at Folly Farm, after which the Battalion marched past the ex-officers, the salute being taken by Lieut.-Col. Dade.

On the 13th November an inter-company relief took place, A Company moving to Beech Hill, and its billets at Littlegrove being occupied by B Company.

At Christmas 48 hours' leave was granted to every member of the Battalion, two leave parties being formed for the purpose.

During this period the Reserve Battalions of the 1st London Division were stationed in all parts of the Home Counties, and the supervision of training by those responsible was naturally extremely difficult; and it was consequently decided to bring together all these battalions into one Divisional camp, the site selected being near Salisbury Plain.

The move to Salisbury took place in January 1916, the 4/4th Battalion proceeding on the 11th to No. 7 Camp, Hurdcott (between Salisbury and Shaftesbury), where it found itself for the first time in company with the 4/1st, 4/2nd, and 4/3rd Battalions, the remainder of the Division being quartered at Hurdcott and Fovant.

No troops of the 4th London Regiment were after this date quartered at Barnet, but before finally saying farewell to this the first station of so many hundreds of the members of the Regiment, we must once more express the indebtedness of the Regiment not only to those gentlemen who so generously afforded the Battalion the use of such excellent training grounds, but also to Mr Kingwell and Mr W. H. Vernon, the owners respectively of Beech Hill and Littlegrove, for the pains taken by them to render these houses comfortable for the troops, and to the many local residents who extended kindness and hospitality to the Battalion, among whom Mr Eldred of Cockfosters must not be forgotten.
