There are actually two distinct episodes where Bilbo saves
the dwarves, if you put aside his "saving" of the whole tale at the end when he takes
the Arkenstone to stop war. I will talk about Chapter 8 and how Bilbo rescues the
Dwarves from the pesky spiders.
When Bilbo finds the
Dwarves after waking up (helped by his enchanted ring that makes him invisible) he
realises that they have been paralysed and wrapped up in spiderwebs by the Spiders.
Bilbo realises that the death of his comrades is imminent and thus has to act. Using his
skill at throwing stones, he throws one at the spider just about to kill Bombur, and
kills the spider. Although Bilbo is invisible, the spiders have a good idea of where the
stone comes from and thus try to capture Bilbo, who easily eludes them and thus
conceives his plan:
readability="13">The idea came to him to lead the furious spiders
further and further away from the dwarves, if he could; to make them curious, excited
and angry all at once. When about fifty had gone off to the place where he had stood
before, he threw some more stones at these, and at others that had stopped behind; then
dancing among the trees he began to sing a song to infurtate them and bring them all
after him, and also to let the dwarves hear his
voice.Bilbo deliberately
taunts the spiders by singing rude songs at them mocking them. His plan works very well
and he doubles back to the Dwarves, killing the guard spider and freeing them and they
fight their way free until the Spiders give up the chase and leave them
alone.What is important to note thematically is that this
episode represents a further development of Bilbo Baggins. He, independently and without
the advice of anyone else, shows his true heroic nature by single handedly saving the
Dwarves. Also note the importance of the naming of his sword as Sting. This clearly
shows he is beginning to see himself as a hero and recognise his true worth, as he is
acknowledging that he is worthy of a "named" sword with its own history like Gandalf and
Thorin are.
