But after the first onset, in which hundreds were killed, there began the real noise of battle--fierce shouting, the shrill cries of wounded and maddened horses as they struck with their feet, and bit as fiercely at the fighting foe as did their masters. The mist cleared slowly, and, when it had wholly lifted, the fight was spread over every part of the field of siege. Ali Wad Hei's men had gathered themselves together after the first deadly onslaught, and were fighting fiercely, shouting the Muslim battle-cry, "Allah hu achbar!" Able to bring up reinforcements, the great losses at first sustained were soon made up, and the sheer weight of numbers gave them courage and advantage. By rushes with lance and sword and rifle they were able, at last, to drive David's men back upon their old defences with loss. Then charge upon charge ensued, and each charge, if it cost them much, cost the besieged more, by reason of their fewer numbers. At one point, however, the besieged became again the attacking party. This was where Achmet Pasha had command. His men on one side of the circle, as Ebn Ezra Bey's men on the other, fought with a valour as desperate as the desert ever saw. But David, galloping here and there to order, to encourage, to prevent retreat at one point, or to urge attack at another, saw that the doom of his gallant force was certain; for the enemy were still four to one, in spite of the carnage of the first attack. Bullets hissed past him. One carried away a button, one caught the tip of his ear, one pierced the fez he wore; but he felt nothing of this, saw nothing. He was buried in the storm of battle preparing for the end, for the final grim defence, when his men would retreat upon the one last strong fort, and there await their fate. From this absorption he was roused by Lacey, who came galloping towards him. "They've come, Saadat, they've come at last! We're saved--oh, my God, you bet we're all right now! See! See, Saadat!" David saw. Five steamers carrying the Egyptian flag were bearing around the point where the river curved below the town, and converging upon David's small fleet. Presently the steamers opened fire, to encourage the besieged, who replied with frenzied shouts of joy, and soon there poured upon the sands hundreds of men in the uniform of the Effendina. These came forward at the double, and, with a courage which nothing could withstand, the whole circle spread out again upon the discomfited tribes of Ali Wad Hei. Dismay, confusion, possessed the Arabs. Their river- watchers had failed them, God had hidden His face from them; and when Ali Wad Hei and three of his emirs turned and rode into the desert, their forces broke and ran also, pursued by the relentless men who had suffered the tortures of siege so long. The chase was short, however, for they were desert folk, and they returned to loot the camp which had menaced them so long.
