Many adverse critics of high speed maintain that it is the weapon of the weaker Fleet, the only advantage conferred being the ability to refuse an action by running away: two cases may be cited from the actions of the late war in the East showing the fallacy of this argument and that the Japanese successes were solely due to a command of speed. In the battle of the 10th August, 1904, after the preliminary manœuvres, the Russian Admiral turned to the eastward at 2.30 p.m. to escape to Vladivostok. The Japanese Fleet was then on the starboard quarter of the Russian and practically out of range. Captain Pakenham, the British Naval Attaché, who was on board Admiral Togo’s flagship, in his report, states that the “‘Tzæsarevitch’ (leading the Russian line) was almost out of sight.” A slightly superior speed in the Russian line would have ensured their escape, but the excess of speed lay with the Japanese and they slowly drew up into range and reopened the action; but it was late in the evening before they drew far enough ahead to concentrate a heavy fire on the leader of the Russian line and so break up their formation. When this was accomplished it was nearly dark and the Russians, though thrown into confusion and beaten, were not destroyed, for the approaching darkness and the destroyer threat necessitated the Japanese Battle Fleet hauling off, yet the retreat to Vladivostok was prevented. A higher speed in the Japanese line would have wrought confusion to the Russians earlier in the day, and probably have allowed a sufficient period of daylight for their total destruction. Again. At the opening of the Battle of the Sea of Japan in May, the Japanese Fleet, due to skilful handling, held a commanding position, giving a concentration of fire on the heads of the Russian lines. Had they not possessed superior speed, the Japanese would rapidly have lost this advantage, as the Russians turned away to starboard and compelled the Japanese to move along a circle of larger radius; their greater speed enabled the Japanese to maintain their advantage and so continue the concentration of fire on the Russian van until so much damage had been inflicted that the Russians lost all order and were crushed. These, therefore, are two of the most convincing instances that could now be given, where speed was of overwhelming tactical value to the victorious side, and such evidence is unanswerable and is a justification of the speeds adopted in the designs of the new ships.
