Before the arrow even hit the Dwarf was reaching for his pickaxe out of instinct. As he turned and raised his shield he grabbed a throwing axe and let it loose, only catching it by the ring at the bottom of the handle at the lost moment when he saw the elf aiming for Darcyn. He groaned and then shouted "Yeah ya better run wazzock!" when the elf left. He would have to throttle that pointy ear later, but perhaps give word to the other Dwarfs that they had reason to throttle him too. More than usual for elves, that is. 

As he was saying his words he combined that with a counter-charge upon Darcyn his pole axe held half-way to be shortened and to make grappling of his weapon easier, whereas his shield was held lower to knock the man down. Even if Darcyn was stronger, a Dwarf to the legs was almost guaranteed to make a man go on his arse. Besides, Darcyn would be distracted by the arrow, and Oid had to press his advantage. He did not see if it struck armour or if it went in but the shock was just perfect.
