There were, as well, more profound and subtle changes in thoughts and habits. The restraints of discipline and the very exacting character of military life and training gave them self-control, mental alertness. At the beginning, they were individuals, no more cohesive than so many grains of wet sand. After nine months of training they acted as a unit, obeying orders with that instinctive promptness of action which is so essential on the field of battle when men think scarcely at all. But it is true that what was their gain as soldiers was, to a certain extent, their loss as individuals. When we went on active service I noted that men who were excellent followers were not infrequently lost when called upon for independent action. They had not been trained to take the initiative, and had become so accustomed to having their thinking done for them that they often became confused and excited when they had to do it for themselves. Discipline was an all-important factor in the daily grind. At the beginning of their training, the men of the new armies were gently dealt with. Allowances were made for civilian frailties and shortcomings. But as they adapted themselves to changed conditions, restrictions became increasingly severe. Old privileges disappeared one by one. Individual liberty became a thing of the past. The men resented this bitterly for a time. Fierce hatreds of officers and N.C.O.s were engendered and there was much talk of revenge when we should get to the front. I used to look forward with misgiving to that day. It seemed probable that one night in the trenches would suffice for a wholesale slaughtering of officers. Old scores were to be paid off, old grudges wiped out with our first issue of ball ammunition. Many a fist-banged board at the wet canteen gave proof of Tommy's earnestness. "Shoot 'im?" he would say, rattling the beer glasses the whole length of the table with a mighty blow of his fist. "Blimy! Wite! That's all you got to do! Just wite till we get on the other side!" But all these threats were forgotten months before the time came for carrying them out. Once Tommy understood the reasonableness of severe discipline, he took his punishment for his offenses without complaint. He realized, too, the futility of kicking against the pricks. In the army he belonged to the Government body and soul. He might resent its treatment of him. He might behave like a sulky school-boy, disobey order after order, and break rule after rule. In that case he found himself check-mated at every turn. Punishment became more and more severe. No one was at all concerned about his grievances. He might become an habitual offender from sheer stupidity, but in doing so, he injured no one but himself.
