Having heard the group approaching Kardol managed to quietly stow his crossbow before pulling his blades.  Once they were in range he watched the scene and noted the one hanging back.  with the three moving forward to engage he found it odd one hung back.  Shrugging to himself he decided it didn't matter just made it an easier target.  so he slipped out of the brush with his short swords in hand and snuck up behind the ogre and slipped a blade up between the space of his armor into the lower right side of his back.
