Gandalf's Troll-Trick

Gandalf's Troll-Trick is the decisive intervention that saves Thorin and Company from being roasted, minced, or squashed by the three trolls William, Bert, and Tom. By returning unseen and impersonating the trolls' voices, the wizard exploits their slow-wittedness and mutual suspicion, spinning out a furious argument that lasts until sunrise, when the trolls are turned to stone. The trick not only rescues the dwarves but also reveals Gandalf's characteristic method: using wit and misdirection rather than brute force to turn an apparently hopeless situation.

Background and Context

The trick occurs during the company's first major peril after leaving the Shire. Lost, wet, and hungry, the dwarves and Bilbo Baggins spot a fire in the woods and send Bilbo ahead to scout. He is caught trying to pick William's pocket, and one by one the dwarves are captured and stuffed into sacks by the trolls, who argue about how to cook them. Gandalf had earlier gone ahead to spy out the road and met friends from Rivendell, who warned him of the trolls; sensing danger, he turned back and arrived just as the trolls were about to roast the dwarves.

What Happens

Gandalf hides behind a tree and begins to throw his voice. When Bert suggests roasting the dwarves immediately, a voice that Bert takes for William's says, "No good roasting 'em now, it'd take all night." This restarts the argument. When the trolls decide to mince and boil them instead, another voice—this time taken for Tom's—objects, "No good boiling 'em! We ain't got no water, and it's a long way to the well and all." The trolls fall to bickering again, each believing the others are contradicting him. The argument escalates until they decide to sit on the sacks and squash the dwarves, but then a voice says, "Dawn take you all, and be stone to you!" At that moment, the sun rises over the hill, and the three trolls are turned to stone, frozen in place forever.

Consequences and Aftermath

With the trolls petrified, Gandalf steps from behind a tree and helps Bilbo down from a thorn-bush. The dwarves are untied, and Bilbo's account of his own encounter with the trolls is heard twice before they are satisfied. Gandalf then leads the company to the trolls' cave, where they find a key dropped by William, open the stone door, and discover a hoard of plunder, including the swords Orcrist and Glamdring, which later prove crucial against the goblins. The gold they find is buried secretly near the river, a reserve that Bilbo recovers on his return journey. The trick thus not only saves the company but also provides them with weapons and wealth that shape the rest of the quest.

Narrative Role and Significance

The Troll-Trick establishes Gandalf's role as a deus ex machina who appears at the last moment, but it also introduces a pattern of narrow escapes that defines the adventure. The trick itself is a pure example of performative speech: Gandalf's words, though not his own voice, cause the trolls to delay until the natural law of troll-kind—that they must be underground before dawn or turn to stone—does the rest. The scene also foreshadows the importance of timing and luck that will recur throughout the story, and it gives Bilbo his first taste of the dangers of burglary, as his attempt to pick a pocket triggers the crisis. The trolls' cave yields the elvish blades that later identify the company as enemies of the goblins, and the buried gold provides Bilbo with a tangible reward at the story's end.
