Immediately after the landing of the army corps under General Oku and the capture of Dalny in the sequel of the battle of Kinchou, the Japanese began to pour troops into Dalny, and soon they had there three divisions under the command of General (afterwards Count) Nogi. This force was henceforth known as the Third Army, that of General Kuroki being the First, and that under General Oku, the Second. The next operation was to land another army at Takushan, which lies on the south coast of Manchuria, between Pitszewo and the estuary of the Yalu. This army was under the command of General (afterwards Count) Nozu, and its purpose was to fill the gap between the First Army and the Second. Nozu's corps thus became the Fourth Army. In fact, the Japanese repeated, in every respect, the plan of campaign pursued by them ten years previously in the war with China.
There was one ultimate difference, however. In the latter war, the force which captured Port Arthur was subsequently carried oversea to the Shantung province, where it assaulted and took the great Chinese naval port at Weihaiwei. But the army sent against Port Arthur, in 1904, was intended to march up the Liaotung peninsula after the capture of the fortress, so, as to fall into line with the other three armies and to manoeuvre on their left flank during the general advance northward. Thus considered, the plan of campaign suggests that General Nogi and his three divisions were expected to capture Port Arthur without much delay, and indeed their early operations against the fortress were conducted on that hypothesis. But, as a matter of fact, in spite of heroic efforts and unlimited bravery on the Japanese side, Port Arthur, with its garrison of thirty thousand men, its splendid fortifications, and its powerful artillery, backed by the indomitable resolution and stubborn resistance of Russian soldiers, did not fall until the last day of 1904, and Nogi's army was unable to take part in the great field-battles which marked the advance of the three other Japanese armies from the seacoast to the capital of Manchuria.
Step by step, however, though at heavy sacrifice of life, the Japanese fought their way through the outer lines of the Russian defences, and the end of July saw the besiegers in such a position that they were able to mount guns partly commanding the anchorage within the port. An intolerable situation being thus created for the Russian squadron, it determined to put to sea, and on August 10th this was attempted. Without entering into details of the fight that ensued, it will suffice to state briefly that the result of the sortie was to deprive the Russian squadron of the services of one battle-ship, three cruisers, and five torpedo craft, leaving to Rear-Admiral Prince Ukhtonsky, who commanded the vessels in Port Arthur, only five battle-ships, two cruisers (of which one was injured), and three destroyers. On August 18th, a gunboat; on August 23d, another battle-ship, and on August 24th another destroyer were sunk or disabled by striking Japanese mines, and it may be said briefly that the Russian squadron thenceforth ceased to be a menace to the Japanese, and that only the land forces had to be counted with.
FIELD OPERATIONS PRIOR TO BATTLE OF LIAOYANG
By the close of June the three Japanese armies under Generals Kuroki, Nozu, and Oku were fully deployed and ready to advance in unison. The task before them was to clear the Russians from the littoral of the Korean Sea and force them through the mountains of Manchuria into the valley of the Liao River. In these operations the Japanese acted uniformly on the offensive, whereas the Russians occupied positions carefully chosen and strictly fortified, where they stood always on the defensive. Five heavy engagements, beginning with Fenshuiling on the 26th of June and ending with Yangtzuling on July 31st, were fought in these circumstances, and in every instance the Japanese emerged victorious. From the commencement of the land campaign until the end of July the invading army's casualties were 12,000, while the Russian losses, exclusive of those at Port Arthur, aggregated 28,000 killed and wounded, and 113 light siege-and field-guns, together with eighteen machine-guns, captured.
THE BATTLE OF LIAOYANG
The first great phase of the field-operations may be said to have terminated with the battle of Liaoyang, which commenced on August 25th and continued almost without interruption for nine days, terminating on the 3rd of September. In this historic contest the Russians had 220,000 men engaged. They were deployed over a front of about forty miles, every part of which had been entrenched and fortified with the utmost care and ingenuity. In fact, the position seemed impregnable, and as the Japanese could muster only some 200,000 men for the attack, their chances of success appeared very small. Desperate fighting ensued, but no sensible impression could be made on the Russian lines, and finally, as a last resource, a strong force of Kuroki's army was sent across the Taitsz River to turn the enemy's left flank. The Russian general, Kuropatkin, rightly estimated that the troops detached by General Kuroki for this purpose were not commensurate with the task assigned to them, whereas the Russians could meet this flanking movement with overwhelming strength. Therefore, Kuropatkin sent three army corps across the river, and by September 1st, the Japanese flanking forces were confronted by a powerful body.
Strategists are agreed that, had Kuropatkin's plans found competent agents to execute them, the Japanese advance would have been at least checked at Liaoyang. In fact, the Japanese, in drafting their original programme, had always expected that Nogi's army would be in a position on the left flank in the field long before there was any question of fighting at Liaoyang. It was thus due to the splendid defence made by the garrison of the great fortress that Kuropatkin found himself in such a favourable position at the end of August. But unfortunately for the Russians, one of their generals, Orloff, who had thirteen battalions under his command, showed incompetence, and falling into an ambuscade in the course of the counter-flanking operation, suffered defeat with heavy losses. The Japanese took full advantage of this error, and Kuropatkin, with perhaps excessive caution, decided to abandon his counter-movement and withdraw from Liaoyang. He effected his retreat in a manner that bore testimony to the excellence of his generalship. The casualties in this great battle were very heavy. From August 25th, when the preliminary operations may be said to have commenced, to September 3rd, when the field remained in the possession of the Japanese, their losses were 17,539, namely, 4866 in the First Army, 4992 in the Fourth, and 7681 in the Second, while the Russian casualties were estimated at 25,000.
BATTLES OF SHAHO AND OF HEIKAUTAI
On the 2nd of October, General Kuropatkin issued from his headquarters in Mukden an order declaring that the "moment for the attack, ardently desired by the army, had at last arrived, and that the Japanese were now to be compelled to do Russia's will." Barely a month had elapsed since the great battle at Liaoyang, and it still remains uncertain what had happened in that interval to justify the issue of such an order. But the most probable explanation is that Kuropatkin had received re-enforcements, so that he could marshal 250,000 to 260,000 troops for the proposed offensive, and that his news from Port Arthur suggested the necessity of immediate and strenuous efforts to relieve the fortress. His plan was to throw forward his right so as to outflank the Japanese, recover possession of Liaoyang, and obtain command of the railway.
