After Bilbo escaped the Goblins, he went to look for Gandalf and the dwarves. He was just about to go back to look for them, when he heard voices between the trees. They did not sound like Goblins, so he got close and found his friends. They decided to move fast to put more distance between them and the Goblins. While they continued their journey, they were struggling to find food. They reached a clearing, the sun was starting to set when they heard the howling of Wargs. They ran swiftly to climb the trees at the sides of the clearing and saw hundreds of Wargs approaching from the forest. Apparently, that clearing had been a meeting place for the Wargs. They were safe from the Wargs up in the trees but since Gandalf understood their language, he could tell that the Goblins were supposed to meet them there. The Wargs knew they were up there and were not planning on letting them escape. Gandalf realized in how bad of a situation they were, so he grabbed the pinecones and lit them with a blue flame. Gandalf casting the pinecones down at the Warg,s the pinecones easily ignited the Wargs' coat and it easily spread from Warg to Warg. There was a huge commotion in the forest and the great Eagles, who watched over those parts, started to wonder what was happening. The Lord of the Eagles decided to find out what was going on. The Eagles usually stopped the Goblins from any mischief that they were up to. The Goblins reached the clearing and soon came up with a plan, they started to drive the fire around the trees were Bilbo and the company were hiding. A ring of fire engulfed Bilbo, Gandalf and the dwarves. Soon the trees were also on fire and the company could not escape. As Gandalf was preparing to leap from the trees and fight one last stand, one of the Eagles grabbed him with its talons and flew away. One by one, the Eagles grabbed each member of the company and carried them away and saved them from the fire. The Eagles were in friendly terms with Gandalf and they took the company to the Great Shelf up in the mountains. The Eagles agreed to take them to back to their path and far from the misty mountains, they also agreed to restock their supplies. When they reached their destination, Gandalf disappoints the Company by telling that he must leave to attend other matters but he will stay with them until they have ponies, more supplies, and are ready to continue on their journey. Gandalf tells them that they would have to go to Mirkwood alone. He leads Bilbo and the dwarves to the house of Beorn. Beorn was a skin-changer, sometimes he was a huge black bear, and sometimes he was a tall black-haired man. Beorn lived in a huge wooden house in the woods, outside of Mirkwood. Gandalf had a plan, in order to avoid startling Beorn with such a big company, he told the Hobbit and the dwarves to come few at a time. Gandalf amuses Beorn by telling him the story of their adventure, he is interested by Gandalf story given that he despises Goblins, Beorn was very amused with the fact that they had killed the Great Goblin. Beorn offers the company, the shelter and supplies that they needed and tells them that the Wargs and Goblins were preparing an attack party to find the company. Beorn tells them that the elvish path in the north will be safer from the attack party, but will still be very dangerous and he warns them to never stray from the path. Before the company sets off, Beorn provides them with supplies and ponies to carry them to the start of the path. When they reach the gate to the path, Gandalf announces that he will not go with them from that point. Gandalf leaves wishing them the best of luck and reminding them to never stray from the path. There are dark creatures lurking through Mirkwood that even Gandalf does not know about. The company starts their journey through the forest path. The night came while Bilbo and the dwarves where in Mirkwood. They could see eyes staring at them in the night. Soon as the days passed, the forest grew thicker and the company could not tell night from day. The forest was wearing down the members of the company and everyone wanted to get out of Mirkwood. Bilbo and the dwarves were starting to loose their morale. After a few days, they found a stream which Beorn had warned them not to touch. They manage to cross the stream with a boat they found, but Bombur fell and the waters put him to sleep. Bombur does not wake up for days and the dwarves take turns carrying him. The dwarves were almost out of food and they were starting to wonder if they would come out alive. One night they saw a light flickering between the trees. The company leaves the path, ignoring Gandalf's and Beorn's warnings, and goes to inspect it looking for food. They find a clearing, were they see elves feasting and singing. At the moment the dwarves burst into the clearing, all lights disappear and they are left in the dark. The same thing happens again two more times, but on the last occasion they cannot find one another and become separated. Bilbo is left alone in Mirkwood unable to find the path. Bilbo is exhausted and cannot find his friends so he decides to rest. He wakes up to a a huge spider that was advancing towards him. Bilbo reaches for his sword and kills the spider. At that moment Bilbo decides to name his sword, and he names it: Sting. He heads to look for the dwarves and finds them tangled in spiderwebs hanging from a tree. Bilbo lures the spiders away from the dwarves by wearing his ring so the spiders cannot see him. Bilbo cuts the dwarves free but when the spiders come back they can hardly fight due to spider venom. When the company starts to loose hope the spiders suddenly retreat and they find themselves in one of the clearings used by the elves. There they realize that Thorin was nowhere to be seen. Thorin had been taken prisoner by the elves, the Elvenking questions Thorin about their journey but he is not willing to talk. Thorin is placed in a dungeon but the elves are good, they feed him and treat him well. After Bilbo and the dwarves escaped the spiders, they were captured by wood elves and brought to the Elvenking's palace. Bilbo was unseen by the wood elves given that he was wearing his ring. The other dwarves are questioned but are, like Thorin, not willing to talk. The dwarves are thrown into the dungeon. Bilbo who was still invisible followed them to their cells and whispered to them plotting an escape. Bilbo learns that the elves are exchanging goods with the men of Lake Town via barrels that were sent down the river. Empty barrels are stored in a room with an exit to the river. In the storeroom Bilbo finds a guard napping and he steals the guard's keys. He frees the dwarves and decides that it was the right moment to follow his escape plan. Bilbo helps each dwarf into an empty barrel and sends them down the river. He too hops into an empty barrel, the gates open and they speed down the river towards Lake Town.

“Somehow the killing of the giant spider, all alone by himself in the dark without the help of the wizard or the dwarves or of anyone else, made a great difference to Mr. Baggins. He felt a different person, and much fiercer and bolder in spite of an empty stomach, as he wiped his sword on the grass and put it back into its sheath.
“I will give you a name,” he said to it, “and I shall call you Sting.” (188-189)
This quote depicts Bilbo's thoughts, after his encounter with the giant spider. This is one of the most important events in the book for Bilbo. This is the first time Bilbo has defeated a creature in one on one combat without the help of any of his friends or his ring. This feat gives Bilbo the courage and confidence he really needed in that desperate time were he was alone. His victory gave him new hope and courage to go look for his friends. From this point forward, Bilbo shows that he is not just acting for his benefit, but the benefit of everyone in the company. In Middle Earth, swords that have a name are normally symbolic and have a great impact upon foes. In this story, even though Sting had no previous reputation, Bilbo makes his enemies know the name of his sword and builds its reputation. Usually swords with names are carried and used by great famous heroes, that have accomplished great deeds and by the naming his sword, he is slowly becoming a hero himself.
“These questions they asked over and over again, and it was from little Bilbo that they seemed to expect to get the answers. From which you can see that they had changed their opinion of Mr. Baggins very much, and had begun to have a great respect for him (as Gandalf had said they would)” (198)
Gandalf had always told the dwarfs that they would end up thanking him for bringing Bilbo on their quest, but this was never taken too seriously. In this part of the book, the dwarves wouldn't have survived without Bilbo. Bilbo started his adventure being considered a burden to the group, but he later started to become a leader to the group, who saved them many times. After Bilbo saved the dwarves, they started to relay on him to get them out of their problems. Without Bilbo, their quest would most likely never have been completed and even though he seemed like the person that was less capable of doing the job, he ended up adapting and even being the best companion the dwarves could have asked for. Bilbo's story is practically a depiction of The Hero's Journey, as throughout his adventure he slowly becomes the hero of the story, while fighting many obstacles and completely leaving his comfort zone.
I feel as if this part of the book was the most important for Bilbo. His character evolved a lot in this section of the story and became a strong leader after Gandalf left them. The Bilbo from the past, who lived comfortably in his hobbit-hole, would never have imagined to become such a strong character that played a crucial role on a deadly adventure. Bilbo changed his role in the company, from someone that depended on others to survive, to someone that the other members depended on to survive. This section marked Bilbo's change into a totally different person.
