Whether slang, profanity, or colloquialisms have cut into our ordinary speech to such an extent as to keep us at a loss for the apt word, or whether we have grown careless or slovenly in our habits of expression, is a matter with which we are not concerned here. We do know that we are continually hampered by our inability to state absolutely our meaning. This lack of skill in composition which besets us, we must overcome in our profession, for the sake of the lives dependent upon our words. Napoleon sitting at his desk scribbling off orders and messages as fast as his nimble fingers can travel, his secretaries standing about him grasping each finished piece from under his pen and sending it off immediately by courier without revision or correction, is a dazzling picture for the military leader to contemplate. In his writing, a commander capable of carrying out single-handed all the phases and minor items of the mightiest of campaigns could, no doubt, be precise and accurate habitually. He _was_ a genius. Yet Napoleon had had long years of practice in putting his will into words; for, we are told, he began to compose orders and to think tactically and strategically at a time of life when most of us have not even chosen our careers. If, then, we can try our hand at transcribing our ideas in as formative a period as possible in our military careers, we, too, may attain a proficiency that will become a second nature with us. At least, we may put behind us a great part of this uninteresting but indispensable work of learning to control our language, before we confront the more serious task of straightening out tactical and strategical difficulties in the presence of the enemy. Incidentally, while we are on our way in our progress in expression, we may pick up much valuable military information. In our practice with tactical language we must make use of certain facts which have been found by experience appropriate to certain happenings connected with officers’ and soldiers’ duties. We shall be in constant touch with the workings of patrols, advance guards, outposts, and forces in battle. Like so many reporters we shall be present at maneuvers putting our notes into graphic and specific form.
