A fierce artillery duel had meanwhile been fought between the Japanese batteries near Wiju and the Russian positions around Kiu-lien-cheng. In this battle of the giants the Russians were completely outmatched--another triumph of Japanese secrecy and prevision. Unknown to the enemy the Japanese had brought by sea to the Yalu a large number of quick-firers and heavy guns, and, most important of all, several howitzers. To these the Russians could only oppose a limited number of field-pieces. A movement of Japanese infantry towards the crest of the hills on the Korean side drew the fire of the Russian batteries and disclosed their position. They were at once answered by an appalling cannonade from the Japanese batteries. From the islands in the river, from the heights north and south of Wiju, the Japanese rained a murderous fire of shell and shrapnel upon the luckless Russian gunners. There was no escape, for they had not reckoned with the howitzers cunningly placed in pits on the islets beneath, and able to search the whole Russian position with high-angle fire. The hills seemed to wilt under the storm; the earth was riddled, the very rocks were rent with the hail of lead and steel scattered by the bursting charges of the terrible Shimose powder. A thick pall of poisonous smoke hung over the devoted Russian batteries; nothing could live under this shattering bombardment. The Russians stuck to their guns like heroes; never certainly did soldiers deserve better of their country. But gradually their fire slackened, then died away: the gunners lay dead at their posts.
That night the Guards and the Second Division of the Japanese army were passed by two bridges across the river, and took up a position on the right bank, sheltered under the bluffs or in the hollows in the sandy bed of the stream. The Second Division had crossed somewhat below Wiju to an island on the far side of the channel, the Guards immediately opposite Tiger Hill. The Russians were now threatened with a frontal attack by these two divisions--the Second operating direct from the Yalu, the Guards across the mouth of the Ai-ho--while the Twelfth Division, higher up the Ai-ho, was ready to attack them in flank.
