And when the unicorn got to the top the hounds were close behind him, so that he suddenly whipped round his great single horn and stood before them threatening. Then the hounds bayed about him, but the horn waved and bowed with such swift grace that no hound got a grip; they knew death when they saw it, and eager though they were to fasten upon him they leaped back from that flashing horn. Then Orion came up with his bow, but he would not shoot, perhaps because it was hard to put an arrow safely past his pack of hounds, perhaps because of a feeling such as we have to-day, and which is no new thing among us, that it was unfair to the unicorn. Instead he drew an old sword that he was wearing, and advanced through his hounds and engaged that deadly horn. And the unicorn arched his neck, and the horn flashed at Orion; and, weary though the unicorn was, yet a mighty force remained in that muscular neck to drive the blow that he aimed, and Orion barely parried. He thrust at the unicorn's throat, but the great horn tossed the sword aside from its aim and again lunged at Orion. Again he parried with the whole weight of his arm, and had but an inch to spare. He thrust again at the throat, and the unicorn parried the sword-thrust almost contemptuously. Again and again the unicorn aimed fair at Orion's heart; the huge white beast stepped forward pressing Orion back. That graceful bowing neck, with its white arch of hard muscle driving the deadly horn, was wearying Orion's arm. Once more he thrust and failed; he saw the unicorn's eye flash wickedly in the starlight, he saw all white before him the fearful arch of its neck, he knew he could turn aside its heavy blows no more; and then a hound got a grip in front of the right shoulder. No moments passed before many another hound leaped on to the unicorn, each with a chosen grip, for all that they looked like a rabble rolling and heaving by chance. Orion thrust no more, for many hounds all at once were between him and his enemy's throat. Awful groans came from the unicorn, such sounds as are not heard in the fields we know; and then there was no sound but the deep growl of the hounds that roared over the wonderful carcase as they wallowed in fabulous blood.
