now when snorri and his folk came to the garth , it is not told that any words befell there , but straightway they set on arnkel , and chiefly with spear-thrust , which arnkel put from him with the sledge-runner , and many of the spear-shafts were broken thereby , nor was arnkel wounded ; but when they had spent their shot-weapons , then thorleif kimbi ran at the garth and leapt up on to it with sword drawn , and arnkel smote at him with the sledge-runner , and thorleif dropped down away from the stroke out of the garth , and the runner smote against the garth wall , and up therefrom flew a piece of frozen turf ; but the sledge-runner was broken at the mortice , and part thereof fell out over the garth .
