We were serving a common ideal, without tribal emulation, and so could not hope for “esprit de corps.” Ordinary soldiers were made a caste either by great rewards in pay, dress and privilege: or by being cut off from life by contempt. We could not so knit man to man, for our tribesmen were in arms willingly. Many armies had been voluntarily enlisted: few served voluntarily. Any of our Arabs could go home without penalty whenever the conviction failed him: the only contract was honour.

Consequently we had no discipline in the sense in which it was restrictive, submergent of individuality, the Lowest Common Denominator of men. In peace-armies discipline meant the hunt, not of an average but of an absolute; the hundred percent standard in which the ninety-nine were played down to the level of the weakest man on parade. The aim was to render the unit a unit, the man a type; in order that their effort might be calculable, and the collective output even in grain and bulk. The deeper the discipline, the lower was the individual excellence; also the more sure the performance.
