but when the thralls saw the fall of hawk , they took to their heels and ran off on their way home , and arnkel chased them all along beyond oxbrents , and then turned back and drave home with him the wood-horses , and took the wood off them , and then let them loose , and bound the load-ropes on them , and they were then turned on their way out along the fell , and they went till they came home to holyfell .
