It is important in military matters that a writer shall express definitely the ideas he intends to convey and in such phraseology that there can be no misunderstanding of the language used. Carelessly or improperly phrased instructions have caused many miscarriages of military plans. The attainment of perfection in the use of language is a matter of painstaking study and the gradual refinement of practice. Merely dreaming of what one will do when responsibility is thrust upon him is not the way to prepare for successful achievement. It is the duty of every self respecting officer to be ready to do not only his best but to do what is right. When one has qualified himself to write or dictate orders and instructions properly he has already learned to interpret those he may receive from others. Accuracy of language demands discipline of mind. Under our system of raising war armies much has had to be entrusted to men without either discipline of mind or of character. This makes it necessary for officers not only to be qualified themselves to prepare and to interpret orders, but to teach the art to others. Carelessly written instructions are like contoured maps with the base data omitted, leaving one in doubt as to whether he is observing a hill or a depression. A recent instance of such carelessness, coming under my observation, may serve to illustrate this: orders were received at my headquarters to call out certain reservists for actual service and direct them to report at Fort Wayne, Indiana. In the execution of the order individual telegrams were dispatched during the night. As orders had been received previously to turn over for the training of such reservists several permanent posts, including Fort Wayne, near Detroit, Michigan, telegraphic inquiry was made to find out if a mistake had been made. The reply established that the Post of Fort Wayne, Michigan, and not the City of Fort Wayne, Indiana, was intended. Modern warfare of nations-in-arms is vastly different from the campaigns and open field fighting of the smaller armies of past wars. Nations no longer entrust the preparation and solution of their military problems to old type of practical soldiers. Military Academies, War Colleges, and General Staff Colleges have become necessary to insure that only trained men shall be entrusted with the preparation of instructions for the employment of the forces. To combine the study of tactical problems, the preparation of orders and the correct use of language, as contemplated by Major Ganoe, will afford a great advantage to the student of today, and should make the diaries, journals, and war histories of the future finished writings without necessity for editing. These are the true sources of military history, a knowledge of which is essential to the ambitious officer desirous of perfecting himself in his profession.
