The second of the two incidents alluded to above was an alliance between England and Japan, signed on January 30, 1902. The preamble of this agreement—the first of its kind ever concluded between England and an Oriental power—affirmed that the contracting parties were solely actuated by a desire to preserve the status quo and the general peace of the Far East; that they were both specially interested in maintaining the independence and territorial integrity of the empires of China and Korea, and in securing equal opportunities in these countries for all nations; that they mutually recognized it as admissible for either of the contracting parties to take such measures as might be indispensable to safeguard these interests against a threat of aggressive action by any other power, or against disturbances in China or Korea, and that, if one of the contracting parties became involved in war in defence of these interests, the other should maintain strict neutrality and endeavour to prevent any third power from joining in hostilities against its ally. Finally, should a third power join in such hostilities, then the other contracting party promised to come to the assistance of its ally, to conduct the war in common, and to make peace by mutual agreement only. The alliance was to hold good for five years from the date of signature, but if either ally was engaged in war at such time, the alliance was to continue until the conclusion of peace.
It is unnecessary to dwell upon the influence exerted by this compact on the Russo-Japanese war. It kept the field clear for Japan and guaranteed her against a repetition of such a combination as that which must be regarded as the remote cause of the struggle.
THE EARLY PHASES OF THE WAR
Japan's great problem in crossing swords with Russia was to obtain a safe avenue for her troops over the sea. Russia might at once have gained an overwhelming advantage had she seized and controlled the lines of communication between the Japanese islands and the continent of Asia. Her strategists can scarcely have failed to appreciate that fact, and would doubtless have acted accordingly had they obtained a few months' leisure to mass an overwhelmingly strong fleet in the seas of China and Japan. They had such a fleet actually in esse; for, at the moment when war broke out, the Russian squadrons assembled in the East, or en route thither, comprised no less than fifty-nine fighting ships, mounting 1350 guns and manned by 18,000 men. But these figures included the Mediterranean squadron which, surprised by the outbreak of hostilities, abandoned its journey to the Pacific. Obviously, Japan's wisest course was to anticipate the combination of Russia's sea forces, and consciousness of that fact operated to hasten the current of events.
Port Arthur, where the bulk of the Russian Pacific squadron lay, is somewhat difficult of ingress and egress. On January 31, 1904, the operation of extracting the ships and parading them outside was commenced, being brought to a conclusion on February 3rd, whereafter the squadron steamed out to sea, and, having made a short cruise off the coast of the Shantung promontory, returned to its position on the following day. The fleet taking part in this manoeuvre consisted of twenty-six ships, and the whole Russian naval force then in eastern Asia comprised seven battle-ships, four armoured cruisers, seven protected cruisers, four gunboats, six sloops, twenty-five destroyers, two mining transports, and fourteen first-class torpedo-boats.
The Japanese, on their side, had six battle-ships, eight armoured cruisers, thirteen protected cruisers, fourteen small cruisers, nineteen destroyers, and eighty-five torpedo-boats. This enumeration shows a numerical superiority on the Japanese side, but in fighting capacity the two fleets were nearly equal. For, though the Russians possessed seven battle-ships to six Japanese, the latter had better gun-protection and greater weight of broadside fire than the former; and though Japan could muster eight armoured cruisers against Russia's four, the latter were supplemented by five protected cruisers which ranked far above anything of the same class on the Japanese side.
THE FIRST NAVAL OPERATION
When the Russian ships returned on the 4th of February from their cruise off the Shantung promontory, they took up their stations outside Port Arthur, all the harbour lights and beacons being left in position, and no special precaution being taken except that a patrol of three torpedo-boats was sent out. Yet the Russians should have appreciated the presence of danger. For, on the 6th of February, Japan had broken off the negotiations in St. Petersburg, and had given official information of her intention to take measures for protecting her menaced interests. That signified war and nothing but war, and the "Official Messenger" of the same evening published the intimation, which was immediately communicated to Admiral Alexieff at Port Arthur.
The Russian fleet was then divided into three squadrons. The largest body lay off Port Arthur, and two very much smaller squadrons were posted, one at Chemulpo on the west coast of Korea, and another at Vladivostok. It is obvious that such division of the fleet on the eve of hostilities should have been carefully avoided. The ships should all have been held together with an extensive network of scouts so as to enable them swiftly and strongly to fall upon any Japanese transports carrying troops to the mainland, or to meet effectually and crush any attempt of the Japanese squadrons to obtain command of the sea.
On the night of February 8th-9th, three Japanese squadrons of destroyers, aggregating ten vessels, steamed across a calm, moonlit sea and delivered a torpedo attack on the Russian squadron at Port Arthur, the result being that the battle-ships Retvisan and Tsarevitch together with the cruiser Pallada were holed. These battle-ships were the most powerful vessels in the Russian squadron, and the Pallada was a first-class protected cruiser of 6630 tons' displacement. The Japanese destroyers had left Sasebo on the 6th of February and they returned thither uninjured, having materially weakened the Russian fleet. On the day following this surprise, Admiral Togo, the Japanese commander-in-chief, engaged the remains of the Russian squadron with the heavy guns of his battle-ships at a range of eight thousand yards, and succeeded in inflicting some injury on the battle-ship Poltava, the protected cruisers Diana and Askold, and a second-class cruiser Novik. The Russians ultimately retreated towards the harbour with the intention of drawing the Japanese under closer fire of the land batteries, but the Japanese fleet declined to follow after them, and, instead, steamed away. Three days later (February 11th) another disaster overtook the Russians. The Yenisei, one of the two mining-transports included in their fleet, struck a mine and sank so rapidly in Talien Bay that ninety-six of her crew perished. The Japanese had no part at all in this catastrophe. It was purely accidental.
