On February 8, 1904, the first blow fell upon Port Arthur in that famous night attack by the torpedo boats. On February 9th occurred the engagement between the remnant of the Russian fleet and the Japanese fleet under Admiral Togo which ended in the Russian retreat into the harbor and the closing of Port Arthur by sea. On May 26th the Japanese Second Army, which had been landed at Petsewo Bay, attacked the first line of defense at Nanshan, eighteen miles north of Port Arthur, and gave an inkling of the mettle of the Japanese troops by capturing the position in a frontal attack. The Japanese pushed on to Port Arthur and there followed, in quick succession, a series of bloody struggles at the successive lines of defense in which the Japanese would not be denied. The fiercest fight took place at the capture of a double height, Kenshan and Weuteughshan, which Stoessel re-attacked vainly for three days, losing three times as many men as were lost originally in the attempt to hold the position. On May 29th Dalny was occupied, and became the base of the besieging army. A railway runs from Dalny for three miles to a junction with the main line from the north to Port Arthur. On August 9th to 11th the outlying semi-permanent works Taikushan and Shokushan, lying about three and one-half miles from Port Arthur, were taken, and the Russians driven in to their permanent positions. The army detailed for the capture of Port Arthur was 60,000 strong; Stoessel at the date of the battle of Nanshan probably had 35,000 men. Encouraged by their uninterrupted success in capturing Russian intrenchments by dashing frontal attack, the Japanese, particularly after their brilliant success of August 9th to 11th, believed that they could storm the main defenses in like manner. They hurled themselves against the Russian right center in a furious attack upon the line of forts stretching from the railway around the easterly side of the town to the sea. For seven days they battled furiously. But the wave of conquest that had flowed over four lines of defense, broke utterly against the fifth; and after a continuous struggle, carried on day and night, beneath sunlight, moon, and searchlight, they retired completely baffled, with an awful casualty list of 25,000 men.
