The disquieting conditions in respect to man-power were, incidentally, hampering the development of two important combatant branches at this time, the Machine-Gun Corps and the Tank Corps. The heavy demands of these two branches, coupled with the fact that infantry wastage was practically exceeding the intake of recruits, threatened a gradual disappearance of the principal arm of the Service. We had by this time got long past the stage with which, when D.M.O., I had been familiar, where lack of material and munitions was checking the growth of our armies in the field. We had arrived at the stage where material and munitions were ample, but where it was becoming very difficult to maintain our armies in the field from lack of personnel--a state of things directly attributable to the Government's opportunist, hand-to-mouth policy in the matter, and to their disinclination to insist upon practically the whole of the younger categories of male adults joining the colours. The organization of the Tank Corps was finally decided actually while I was acting as D.C.I.G.S. In so far as the general control of Tank design and the numbers of these engines of war to be turned out was concerned, it seemed to me to be a case of "pull devil, pull baker" between the military and the civilians as to how far these matters were to be left entirely to the technicalist; but the technicalist was not perhaps getting quite so much to say in the matter as was reasonable. The personal factor maybe entered into the question.
