When they were not in the line, they were providing working parties; when they were not at work, they were undergoing training. ‘The construction of new communications and the extension of old, more especially in the area south-east of Arras, involved the building of a number of additional roads and the laying out of railways, both narrow and normal gauge. All available men of the fighting units, with the exception of a very small proportion undergoing training, and all labour units were employed on these tasks.’ So far, the Field Marshal in his Despatch, and we may quote Sir A. Conan Doyle’s comment: ‘There were no enslaved populations who could be turned on to such work. For months before the attack the troops ... were digging incessantly. Indeed, the remark has been made that their military efficiency was impaired by the constant navvy work upon which they were employed.’[103] It may be. But Sir Douglas Haig bore testimony, that ‘the time and labour available were in no way adequate, if, as was suspected, the enemy intended to commence his offensive operations in the early spring....’ On January 31st, as we saw, the re-organization of the Division took place. Under the new scheme of nine battalions _plus_ a Pioneer Battalion to a Division, the nucleus of Battalions to be amalgamated arrived from the 49th Division further north. In the 185th Brigade, the 2/6th West Yorkshires were disbanded, and the 2/8th were amalgamated with the 1/8th to form the 8th West Yorks. In the 186th Brigade, the 2/6th West Ridings were disbanded, and the 5th West Ridings were formed out of an amalgamation of the 1st and 2nd Line Battalions. In the 187th Brigade, when it left the line, the disbanded unit was the 2/5th York and Lancasters; the 2/5th King’s Own Yorkshire Light Infantry were amalgamated with the 1/5th as the 5th K.O.Y.L.I.
