The day after the battle with the spiders Bilbo and the dwarves made one last despairing effort to find a way out before they died of hunger and thirst. They got up and staggered on in the direction which eight out of the thirteen of them guessed to be the one in which the path lay; but they never found out if they were right. Such day as there ever was in the forest was fading once more into the blackness of night, when suddenly out sprang the light of many torches all round them, like hundreds of red stars. Out leaped Wood-elves with their bows and spears and called the dwarves to halt.
There was no thought of a fight. Even if the dwarves had not been in such a state that they were actually glad to be captured, their small knives, the only weapons they had, would have been of no use against the arrows of the elves that could hit a bird’s eye in the dark. So they simply stopped dead and sat down and waited—all except Bilbo, who popped on his ring and slipped quickly to one side. That is why, when the elves bound the dwarves in a long line, one behind the other, and counted them, they never found or counted the hobbit.
