The dark spoiled his aim, and he managed only to deflate the rubber boat, leaving Gollum to flounder. Gollum, who couldn't swim, reached out his hand to Bilbo and begged him to pull him out, and, as he did, Bilbo noticed an interesting looking ring on his finger and pulled it off. He would have finished Gollum off then and there, but pity stayed his hand. It's a pity I've run out of bullets, he thought as he went back up the tunnel, pursued by Gollum's cries of rage.
