The war which now unfortunately rages in the Far East has emphasized in striking fashion the new possibilities of naval warfare. The lessons taught are both strategic and tactical, and are political as well as military. The experiences of the war have shown in conclusive fashion that while sea-going and sea-keeping torpedo destroyers are indispensable, and fast lightly armed and armored cruisers very useful, yet that the main reliance, the main standby, in any navy worthy the name must be the great battleships, heavily armored and heavily gunned. Not a Russian or Japanese battleship has been sunk by a torpedo boat, or by gunfire, while among the less protected ships, cruiser after cruiser has been destroyed whenever the hostile squadrons have gotten within range of one another’s weapons. There will always be a large field of usefulness for cruisers, especially of the more formidable type. We need to increase the number of torpedo-boat destroyers, paying less heed to their having a knot or two extra speed than to their capacity to keep the seas for weeks and, if necessary, for months at a time. It is wise to build submarine torpedo boats, as under certain circumstances they might be very useful. But most of all we need to continue building our fleet of battleships, or ships so powerfully armed that they can inflict the maximum of damage upon our opponents, and so well protected that they can suffer a severe hammering in return without fatal impairment of their ability to fight and manœuvre. Of course ample means must be provided for enabling the personnel of the Navy to be brought to the highest point of efficiency. Our great fighting ships and torpedo boats must be ceaselessly trained and manœuvred in squadrons. The officers and men can only learn their trade thoroughly by ceaseless practice on the high seas. In the event of war it would be far better to have no ships at all than to have ships of a poor and ineffective type, or ships which, however good, were yet manned by untrained and unskilful crews. The best officers and men in a poor ship could do nothing against fairly good opponents; and, on the other hand, a modern warship is useless unless the officers and men aboard her have become adepts in their duties. The marksmanship in our Navy has improved in an extraordinary degree during the last three years, and on the whole the types of our battleships are improving; but much remains to be done. Sooner or later we shall have to provide for some method by which there will be promotions for merit as well as for seniority, or else retirement of all those who after a certain age have not advanced beyond a certain grade; while no effort must be spared to make the service attractive to the enlisted men in order that they may be kept as long as possible in it. Reservation public schools should be provided wherever there are navy-yards. * * * * *
