The unresting progress of mankind causes continual change in weapons; and with that must come a continual change in the manner of fighting … The seaman who carefully studies the causes of success or failure … will observe that changes in tactics have not only taken place after changes in weapons, which is necessarily the case, but that the interval between such changes has been unduly long. This doubtless arises from the fact that an improvement in weapons is due to the energy of one or two men, while changes in tactics have to overcome the inertia of a conservative class? but it is a great evil. It can be remedied only by a candid recognition of each change by careful study of the powers and limitations of the new … weapon, and by a consequent adaption of the method of using it to the qualities it possesses, which will constitute its tactics. History shows it is vain to hope that military men generally will be at pains to do this, but that the one who does will go into battle with a great advantage—a lesson in itself of no mean value.
