Soon the heavy casualties incurred by the battalions in France made the sending of large drafts necessary, and the Reserve Battalion began to change completely, with new officers and new men constantly arriving from Caterham. The number of men in the Battalion became so great that there were two thousand five hundred men in barracks, and the problem of accommodation was a very difficult one. Early in 1915, Aylwin huts were erected at Burton's Court, which somewhat relieved the pressure. On the formation of the Welsh Guards in February 1915, five officers and six hundred and thirty-four other ranks were transferred to this new regiment, and in July of the same year, when it was decided to form another battalion of the Grenadier Guards from the Reserve Battalion, the latter automatically became the 5th Battalion. The officers at that time were as follows: _In Command_-- Lieut.-Colonel G. D. White _Major_-- Du Plat Taylor, G. P. _Captains_-- Stewart, E. O. Ellice, E. C. Macdonald, G. G. Taylor, E. R.
