jon was having trouble , his fists although striking many blows were not having so much effect on the enemy of flesh and metal , nw also saw this for he bellowed a war cry and ran towards jon to aid him but he didnt get far for he was felled by a war hammer striking his head , his helmet flew off and landed a good distance away , nw now lay still upon the ground , the creature that had struck the blow was slowly lifting his hammer again this time intent on crushing nws brains from his skull , but before the blow could be dealt jon placed a firm kick to the creatures midriff and it fell backwards to the ground it went to stand , obviously winded as it gasped open-mouthed for air , but an arrow entered its mouth and stopped only after it had exited through the back of the creatures neck .
