On the night of the 25th the Japanese army was massed on the left bank of the river in the following order: On the left, facing the island of Cheun-song-do, was stationed the 2nd Division; the centre, occupying a position to the north of Wiju, was composed of the Imperial Guards' Division; and on the right, still further up the river, the 12th Division was concentrated, in concealment behind some hilly ground, and in readiness for an important move upon the enemy's left, which will be described later. [Sidenote: Clearing the Islands] At dawn on the 26th a sharp rattle of musketry told the Russians that the attack had begun. Detachments from the Guards' Division were firing upon General Sassulitch's sharpshooters stationed on the Island of Kulido. The Russians replied briskly, but the Japanese rifle fire was heavy and well-directed, and at last their position became untenable, in face not only of this infantry attack, but of a searching bombardment opened by some batteries of Kuroki's artillery, which were established on a hill in the rear of Wiju. They therefore retreated to the mainland for shelter. [Sidenote: Guards Half-way Across] No sooner had this retirement been effected than the Japanese prepared to cross over to the island in boats. These craft were all in readiness, and before long a considerable force of the Guards had landed on the island. When this movement was perceived the enemy returned to dispute it; but they were not in large force, and were easily repulsed. A squadron of Cossacks came to their assistance, but the hot fire with which they were received by the Japanese infantry was too much for them, and they were driven back in confusion to the bank below Tiger Hill. The Mikado's Guards continued the pursuit across the ford, and a smart encounter ensued beneath the hill. The fighting was not of long duration, however; the Russians retired; and it became evident that there was no intention seriously to dispute the possession of the island. The attempt made by General Sassulitch's batteries to drive the daring Japanese off the island by shrapnel fire was quite unsuccessful, and the whole defence on this side revealed an unexpected weakness. The Guards' skirmishers occupied all night the ground they had so easily gained. [Sidenote: Parallel Movements] In the meantime, the advance guard of the 2nd Division had carried through the same operations with equal success on the Island of Cheun-song-do. The Russian sharpshooters were driven off in the direction of Chiu-lien-cheng, and the Japanese seized the delta with a small force preparatory to constructing a bridge over the central stream for the passage of the main body of the division.
