Again in the war of 1878 between Russia and Turkey the Russians had only a few light craft in the Black Sea, and the Turkish fleet under Hobart Pasha, weak as it was, held the undisputed command of these waters, and had only to fear some isolated torpedo attacks. In South American civil wars and international conflicts there were duels between individual ships, and some dashing enterprises by torpedo boats, but nothing that could be described as a fleet action between ironclads. The only time a British armoured fleet was in action was against the batteries of Alexandria on the occasion of the bombardment in July, 1882. The forts, badly armed and constructed, and inefficiently defended, were silenced, but a careful examination of them convinced experts that if they had been held by a better-trained garrison, the victory would not have been such an easy matter. This and subsequent experiences have led to the general acceptance of the view that it will be seldom advisable to risk such valuable fighting machines as first-class battleships and armoured cruisers in close action against well-constructed and powerfully armed shore defences. It was not till the summer of 1894 that at last there was another pitched battle between fleets that included a large proportion of armoured vessels. That action off the mouth of the Yalu River will be always remembered as the event that heralded the coming of a new naval power. A long rivalry between China and Japan for the control of Korea had resulted in an outbreak of war between the two empires of the Far East. For an island state like Japan the command of the sea was a necessary condition for successful operations on the mainland of Asia, and for some years she had been building up a powerful fleet, the ships being constructed in foreign yards, as the Japanese yards were not yet in a position to turn out large warships.
