In an army every unit depends for its efficiency upon the system of discipline inculcated by its commander, aided by the spirit of individual enthusiasm which pervades its members; the less the enthusiasm the sterner must the discipline be. Now a D.A.C., as it is familiarly called, is not, in the inner meaning of the phrase, a cohesive unit. In peace it exists only on paper; it is formed during mobilisation by the haphazard collection of a certain number of officers, mostly ‘dug-outs’; close upon 500 men, nearly all reservists; and about 700 horses, many of which are rejections from other and, in a sense, more important units. Its business, as its name indicates, is to supply a division with ammunition, and its duties in this connection are relatively simple. Its wagons transport shells, cartridges, and bullets to the brigade ammunition columns, whence they return empty and begin again. It is obvious that the men engaged upon this work need not, in ordinary circumstances, be heroes; it is also obvious that their rôle, though fundamentally an important one, does not tend to foster an intense _esprit de corps_. A man can be thrilled at the idea of a charge or of saving guns under a hurricane of fire, but not with the monotonous job of loading wagons and then driving them a set number of miles daily along the same straight road. A stevedore or a carter has as much incentive to enthusiasm for his work. The commander of a D.A.C., therefore, to ensure efficiency in his unit, must be a zealous disciplinarian with a strong personality. But Pickersdyke’s new colonel was neither. The war had dragged him from a life of slothful ease to one of bustle and discomfort. Being elderly, stout, and constitutionally idle, he had quickly allowed his early zeal to cool off, and now, after six months of the campaign, the state of his command was lamentable. To Pickersdyke, coming from a battery with proud traditions and a high reputation, whose members regarded its good name in the way that a son does that of his mother, it seemed little short of criminal that such laxity should be permitted. On taking over a section he ‘got down to it,’ as he said, at once, and became forthwith a most unpopular officer. But that, though he knew it well, did not deter him. He made the lives of various sergeants and junior N.C.O.s unbearable until they began to see that it was wiser ‘to smarten themselves up a bit’ after his suggestion. In a month the difference between his section and the others was obvious. The horses were properly groomed and had begun to improve in their condition—before, they had been poor to a degree; the sergeant-major no longer grew a weekly beard nor smoked a pipe during stable hour; the number of the defaulters, which under the new régime was at first large, had dwindled to a negligible quantity. In two months that section was for all practical purposes a model one, and Pickersdyke was able to regard the results of his unstinted efforts with satisfaction.
