the attention of the enemy. This will not be so easy in the future as in the last Russo-Turkish war, although it is true that in that war, boats of a speed of from six to eight knots were used, while the new boats will make their attack at speed of thirteen knots. It is difficult to give any positive opinion as to whether it is best to make an attack in broad day light. In very dark, stormy nights, the enemy will generally be more watchful. A single ship can scarcely be defended effectually, even in the day time, against a flotilla of torpedo boats. Our present experience scarcely enables us to say whether the attacks in the day, or those in the night, have the best chance of success, even assuming there may be a greater loss of life in the former. It may happen that you find an enemy who, having observed a division of torpedo boats coming down upon him, has made every preparation to repel their attack; but it does not follow that he may be able to make an effective defence. Here it would seem that the chances of success are greater in a daylight attack. A ship attacked in the night can make use of the electric light; the assailant should endeavor as long as possible to keep out of sight, and therefore the torpedo boats should be painted of such a color as to be the least conspicuous under the electric light. The usual dark grey colors are conspicuous, inasmuch as they appear much lighter, and indeed become a pure white when seen by the electric light. Experiments in the Black Sea showed that a light brown or chocolate was the least conspicuous color. It is to be remarked that no special code of signals has yet been devised for torpedo boats. In the absence of these two boats belonging to the same fleet may possibly attack one another. The equipment of the torpedo boats with machine guns deserves very careful consideration ; it is still difficult to pronounce an opinion as to their suitability. In making an attack it will be impossible to open fire with these weapons; they can be employed with effect only against boats, or to cover a retreat. The pyroxyline rockets may be found more useful: they have been supplied to torpedo boats; they do not load them too deeply, take up little room, and can be used with equal advantage for signaling purposes both in advancing to the attack and in retiring. The explosion of these rockets on board the ship which is attacked would create no small confusion. The general conclusions to which we have been led by the foregoing observations on attacks by torpedo boats may be summed up as follows: to 1. Attacks by single boats are only to be attempted as a last resource 2. The attack must be made according to a carefully considered plan. 3. The torpedo boats are to be equipped with either the Whitehead or the spar torpedo. 4. A squadron of torpedo boats must be divided into groups; the pioneer group, the assaulting group, and the reserve group. 5. The torpedo should be fired automatically, and only when this plan fails should the electrical firing apparatus be employed. 6. Thespar should be sunk as soon as the boat is reduced to half speed or stopped. At full speed the spar should be triced up clear of the Water. 7. The attack should be made, at a signal from the commander, simultaneously from several points, 8. The speed of the torpedo boats before the attack, until they reach the positions which have been assigned to them, should be regulated according to the speed of the slowest boat. 9. The commander of the division should remain in the rear, with the boats of the reserve group. 10. The torpedo must be brought in contact with the bottom of the unarmored ends of the ships. In order to be able to apply all these rules effectively in war, it is necessary in time of peace to train every torpedo division to apply them as far as possible, under the conditions which would arise in actual warfare. This would be easily effected if the manoeuvres of an attack were intelligently put in practice according to a predetermined plan, against a fleet at anchor and under way, with dummy torpedoes. At the end of the course of instruction, an attack might be made as a test of the efficiency which had been attained with loaded torpedoes against a raft or pontoon towed. It is only after considerable practice that success can be obtained in this new method of warfare. Trials with single boats can only be regarded as a preliminary to manoeuvres with a complete division of boats. They in no way ensure success when a boat is for the first time attached to a division, without having been exercised in making attacks of a similar nature in time of peace.
