Too late the Russian general had realized his fatal error in allowing the Twelfth Division to march unopposed across the hills. Too late he had taken such feverish steps as were now possible in the attempt to retrieve it. He had withdrawn in haste a considerable force from Antung to hold the bluffs on the right bank of the Ai-ho, and hurriedly begun to throw up entrenchments. General Inouye smiled when he learnt of these tardy efforts to stay him; plans carefully thought out for years were not likely to be foiled by bustle at the eleventh hour. Hardly had the sun risen when the battle was begun by a general outburst of artillery fire along the whole of the Japanese lines. There was no response from the enemy; it almost seemed as if the position were already deserted. But soon the order was given to the Japanese infantry to advance to the assault. The three divisions moved forward simultaneously. Bob could not see what the other two were doing, but he watched with tense eagerness as the Twelfth Division dashed down the hillside to the bank of the Ai-ho. A murderous rifle-fire was opened upon them from the Russian trenches. But never a man faltered. Springing on nimbly, some taking what cover the ground afforded, others disdaining precaution, they reached the stream. They plunged in, holding their rifles and pouches above their heads, and forcing their way against the rapid current that swept along breast-high. They had now entered the zone of fire; the surface of the river boiled under the hail of Russian bullets; the turbid waters were red with Japan’s best blood; but to Bob, watching intently from the hill above, the sound of their war-song came floating upon the morning breeze— "Oh! it is easy to cross the Yalu river!" and, with sublime and happy indifference, they struggled on. Look: they are gaining the farther bank. At last—it seems an eternity!—the river is crossed. Up, up they scramble, scaling the bluffs in grim silence now. The air rattles with the crack of rifles, throbs with the thud of heavy guns. Men are falling fast, but the survivors are still pressing on, up the murderous heights, ever drawing nearer to the enemy on the crest. Bob, his whole body a-tingle, can bear his inaction no longer. He turns to a senior officer of the staff: "May I follow them up, sir? I have nothing to do now." "You had better stay with us," replied the officer with a smile, lowering his field-glass; "still, if you wish—"
