86 of the low rounded ridges near the Canal there was no change. Everywhere were the same gently undulating features with occasional woods or copses, the whole seamed by the sunken roads which throughout were one of the salient characteristics of the country over which the Division had fought. These sunken roads, owing to the shelter and security from observation afforded by them and the facility with which they could be organized for defence, were of the greatest importance from the military point of view. It was along such roads as ran approximately north and south that the enemy, after having been pushed out of his last prepared line, put up his most stubborn defence while being pressed back over this open country. Other features of the country which had a certain effect on military dispositions were the little scarps which existed along the edges of most of the valleys in the district. At these points, where the ground rises to form the flat-contoured hills, the earth had usually been cut away to form a little cliff anything from two to six or even more feet in height; the resultant scarp, when facing in the right direction with regard to the enemy, affording shelter from observation. These faces were usually of soft earth, chalk, or crumbly sandstone, and were used to a great extent by both combatants, who burrowed into them and so obtained a certain measure of security from shell fire at the cost of a minimum amount of labour. The shelter thus afforded from the weather conditions was also not to be despised as the autumn crept on, the nights grew longer, and the temperature fell lower. Many hundreds of men of the 46th Division will in future days look back with pleasure to the nights spent in these little, not uncomfortable, bivouacs after a hard day's work either fighting or chasing the “Boche.”
