1. _Regimental Aid Posts._--Just a little behind the firing line, as near to it as possible, often exposed to shell and rifle fire, is the Regimental Aid Post. It may be in a cottage, possibly in a cow-shed, perhaps only under the partial shelter of a hill, with a doctor and a few men of the R.A.M.C. in charge. To it are brought as quickly as possible the men wounded in the firing line. During recent months, however, it has been impossible to bring the wounded even this short distance during the day. It has only been at night that the men in the trenches could remove their wounded hither, or the stretcher-bearers could go out to seek for them. The fire has been so terrible that no one could venture into the open. The men have had to lie where they fell, often in agony, waiting until they could be carried to the aid post to receive first aid from the doctor waiting for them. But the doctor does not always wait; he goes where he is needed most, right into the trenches, risking his life at every step, and there ministers to those who cannot wait to be brought to him. The Rev. E.L. Watson (Baptist chaplain) vividly describes one such outpost as I have indicated. "In the vicinity of the trenches star bombs were constantly being thrown up, causing whole lines of trenches to be under the weird flare. German search-lights swept the whole of the surrounding country, bringing to light every movement of the troops not under cover. "For one brief moment the shaft of light rested on me as I stood watching the scene of battle. The experience is equal to an unexpected cold douche. Night fighting under modern science is, I should imagine, hell let loose, and the surprise to me is that so many should survive the inferno. "From 8 P.M. to 8 A.M. the rush was terrific. In one of the field hospitals no less than seventy odd wounded were treated, about twenty of these requiring chloroform. "Be it remembered that each case is hastily but carefully dressed by the regimental doctor at the Regimental Aid Post before coming in to the field hospital for more thorough treatment, then one realises the enormous amount of work that often falls to the men occupying these positions of grave risk and tough work. "These gentlemen are night and day at the call of the man in the trenches, and gladly make any and every sacrifice to render needed medical and surgical assistance. Each trip they make to the line of fire means that they carry their lives in their hands; for there is more danger getting into the trenches than actually exists in the trenches, because most of the fire passes over our trenches and sweeps the approaches night and day.
