These subaqueous weapons have never been used in an engagement between fleets. In an interesting essay(51) on the subject by Commander Noel, R.N., he recommends or proposes that four torpedo vessels should accompany a fleet, and describes their probable operations as follows:— [Illustration: TORPEDO EXPERIMENTS AT PORTSMOUTH, WITH THE ELECTRIC LIGHT.] “Let us imagine ourselves, then, on board a rakish little craft, fitted for Harvey torpedo work; we can steam sixteen knots; we tow a torpedo on each quarter; and we are so admirably fitted with steel-protecting mantelets that neither officer nor man is exposed either to view or to rifle fire. Our instructions are that on the approach of a hostile force we and our three consorts are to hold ourselves in readiness to charge the enemy’s line, passing through at full speed, and doing all the damage that lies in our power: these orders to be carried into effect in obedience to a preconcerted signal. The enemy is observed approaching, and apparently moving at about ten knots’ speed. The torpedo vessels are let loose, and, choosing the centre of the enemy’s fleet, rush on, steering for a flag-ship leading a column in line ahead. Heavy guns are fired at us as we near, but we are so small and rapid in our movements that no shot takes effect; we are reducing our distance at the rate of a mile in two and a half minutes; soon comes the time of suspense; in a second or two we are passing the flag-ship; the port torpedo is dipped—will it strike her? Suddenly a tug on the wire towing-rope, and it parts. Her bow has been protected, and our torpedo is torn away harmless. However, another mine tows on the opposite quarter, still in working order; we are in the midst of the enemy’s fleet, rushing past one after another at half-minute intervals; our only chance of using our other torpedo is in breaking through the line; our commander is eminent for his skill, courage, and confidence. Little choice is given us, but he observes a rather great interval astern of the fourth ship. ‘Starboard’ is the order, and we break through under her stern; our starboard torpedo is at the same time dipped, and passes under the fifth ship. Owing to a combination of luck and good management, the torpedo takes effect and the enemy is blown up. The other torpedo vessels have thrown the enemy into considerable disorder, but none have succeeded in using their torpedoes with effect. One of them has been struck by a heavy shell and totally disabled, but the whole fleet has passed on without finding it possible to capture or sink her without losing their position in station and being left behind; the thought foremost in every captain’s mind also being that the enemy’s fleet is almost in contact with them, and that the moment to act has arrived.
