what obstacles dose the group encounter while attempting to camp on the mountian? why do they move camp, and what is the result of this?

They climb higher and their first camp is too exposed. They find a cave to camp in but the cave is occupied by goblins and Bilbo's yell is able to alert Gandalf, who disappears. Bilbo and the dwarves are captured, though, They are carried "down, down to Goblin-town"
