The modern protected cruisers which took part in the battle on the Japanese side were the Naniwa, Takachiko, Itsukushima, Hashidate, Matsushima, Akitsushima, and Yoshino. The lowest speed of any of these ships was seventeen and a half knots, and they were armed with Armstrong, Canet, and Krupp heavy guns and a very large number of quick-fire 4.7-inch, and smaller guns.

The Akitsushima and Hashidate were built in Japan; the Itsukushima and Matsushima at La Seyne, in France. The Naniwa and Takachiko were English built, as was also the new Yoshino, with a speed of twenty-three knots, 4150 tons, and one of the finest cruisers afloat in any navy.

The Japanese torpedo flotilla consists of 41 boats more than 100 feet in length; but, as we shall have occasion to see later on, torpedoes were of not much importance in the Yalu battle, owing to the manner in which it was fought, and few of those were present.

The principal dock-yard and naval arsenal of Japan is at Yokosuka; and the whole country is divided into two naval districts or departments, each subject to a vice-minister under the naval minister at Tokio, the capital. The discipline and regulations of the Japanese fleet are modelled upon those of Europe and America much more closely than that of China, and the ships are manned by efficient and well-trained crews, who have excellent and well-instructed officers. So many of the population are engaged in maritime pursuits—either in the fishery or in coasting and carrying on the active communication between the islands composing the empire—that there is a large reserve of hardy, seasoned men to draw upon for service in the navy.

Many of the officers have been educated abroad, some of them being graduates of our own Naval Academy at Annapolis, where, as a rule, they have always stood well in their classes in spite of the difficulty of carrying on their studies in a foreign language. These naval cadets were received at the request of the Japanese government and wore the uniform and were treated in precisely the same way as our own cadet midshipmen, but the Japanese government paid all their expenses.

Thus, though apparently weaker than the Chinese fleet, except in the matter of swift cruisers, the Japanese navy had qualities which gave it the real, practical advantage in the battle of the Yalu. More than ever has it confirmed the theory that speed is the greatest requisite in the sea-fighting of the present day; for it was the swiftness of the Japanese vessels which gained them the advantage in the first place, seconded by rapid and accurate gun-fire.

We shall see that torpedoes had not much opportunity for action, and when used by the Chinese (rather clumsily), failed in taking effect, while there was no use of the ram at all—a manner of offence which many looked to see exemplified in the first great naval battle.

The great sea-fight at the Yalu will not be completely elucidated for some time to come—probably many months—but we know enough about it to be able to give its leading features, mostly from the report made to the Japanese Emperor by an aide of Admiral Ito, who commanded the fleet of Japanese vessels.

This fleet had been for several days in the estuary of Ping-Yang, in the Bay of Korea, co-operating with the land forces upon the river Ta-Tong. On the morning of September 16th the Admiral was advised that Ping-Yang had been captured, and he at once got under way, proceeding to the northward with eleven ships, the names of which have already been given, and the Saikio, a light-armed vessel having on board Admiral Kabiyama, who was senior to Ito, but who did not assume command, as he was only upon a tour of inspection and his vessel was not intended for fighting. The ships were in two divisions.

On the 17th, in the bay of Takuchao, on the coast of Manchouria, they discovered the Chinese fleet, of fourteen ships and four torpedo-boats. It was then about mid-day. As the opposing forces rapidly approached each other it was seen that the Chinese were coming out of the bay in a formation not unlike a closed crescent or wide V; the Japanese fleet being in line abreast, with the Admiral in the centre in the Matsushima. The little Saikio also took place in line, in spite of her feeble armament.
