The introduction of the automobile or fish torpedo led to the building of above-water torpedo vessels by all the great Powers. The idea of discharging this weapon from a submarine boat occupied the attention of numerous inventors, amongst others of Mr. Nordenfelt, of machine-gun fame. Greece and Turkey both bought Nordenfelt submarine boats, but although they achieved a certain amount of success and were certainly the best specimens of under-water fighting vessels extant, they failed to receive wider recognition owing to their serious disadvantages. The possibility of utilising the electric accumulator revived the hopes of the advocates of submarine navigation, and towards the end of the eighties, France added the first under-water torpedo-boat to her navy: since then her interest in the subject has never abated, and although it would be unfair to attribute to all French naval men and officials the ideas as to the superiority of the torpedo vessel to the ironclad put forward by a certain class of writers, it cannot be denied that the question of under-water warfare has attracted more attention in France than in any other country. A few years after the launch of the first French submarine, the _Gymnote_, the U.S. Government purchased the _Holland_, and in the same year ordered six more _Hollands_ of an improved type. When Greece and Turkey purchased Nordenfelt boats there were not wanting those who declared that Great Britain should also add under-water vessels to her navy. The official view was however hostile to such craft. In the early part of 1900, Viscount Goschen said that while close attention had been given by the Admiralty to the subject of submarine boats, they considered that even if the practical difficulties attending their use could be overcome, they would seem to be weapons for “maritime Powers on the defensive.” It seemed to him that the reply to this weapon must be looked for in other ways than in building submarine boats ourselves, for it was clear that one submarine boat could not fight another. It would seem from this that the Admiralty had no very high opinion of the submarine as an offensive weapon. However this may be, an order was placed in the autumn of 1900 with Messrs. Vickers Sons and Maxim for five of the newest “Holland” boats, they being the agents in Europe for the Holland Torpedo-boat Company of New York, and this being the only type available. Not till the statement of the First Lord was published on March 1, 1901, was the fact of the ordering of these boats made public; the secret had indeed been well kept.
