Courage in the Face of the Unknown

“…As he went forward it grew and grew, till there was no doubt about it. It was a red light steadily getting redder and redder. Also it was now undoubtedly hot in the tunnel. Wisps of vapour floated up and past him and he began to sweat. A sound, too, began to throb in his ears, a sort of bubbling like the noise of a large pot galloping on the fire, mixed with a rumble as of a gigantic tom-cat purring. This grew to the unmistakable gurgling noise of some vast animal snoring in its sleep down there in the red glow in front of him.

It was at this point that Bilbo stopped. Going on from there was the bravest thing he ever did. The tremendous things that happened afterward were as nothing compared to it. He fought the real battle in the tunnel alone, before he ever saw the vast danger that lay in wait…”
