Bard kicked the barrel nearest to him as the dwarf inside was squirming and making a lot of noise. He steered the boat into a small harbour and got off, taking the money with him.

In mere seconds, Thranduil had drawn his sword from its sheathe and hacked Narzug's head clean off his shoulders. Mel and Tauriel stared in shock as the body fell limply to the floor and began to twitch violently. 
"What did you do that for?!" Mel protested. "He wasn't finished speaking! We told him you would let him go!"
The Elvenking tilted his head to the side at her. "I did. I freed his wretched head from his miserable shoulders." Thranduil declared in disgust as he stamped on the Orc's legs with a boot, the body stopped twitching.
