Addressing the Questions of Thranduil’s Army in the Hobbit Film

In the first Hobbit film, one common question that arises is how Thranduil and his army were able to hear of Smaug's attack on Erebor and reach the mountain just as it was being evacuated. This conundrum highlights a significant issue in the film's adherence to the Middle-earth geography and the behavior of its creatures.

The Dragon’s Impact and Warnings

A dragon, like Smaug, is not a covert operator. Its arrival would invariably be accompanied by loud and unmistakable noises, drawing the attention of nearby inhabitants and scouts. Thranduil, the king of the Woodland Realm, was already aware that the inheritance of Erebor by Thorin Oakenshield could attract unwanted attention. Therefore, it was highly probable that he and his scouts received early warnings about the impending threat.

Aiding Forces: Birds and Beasts of Middle-earth

The creatures of Middle-earth, particularly birds, could play a crucial role in disseminating news. Birds such as the rooks of Erebor who can communicate and travel at much greater speeds than humans could have quickly informed both Laketown and the Woodland Realm. This network of avian messengers would have made it possible for Thranduil's forces to mobilize promptly.

The Role of Elven Perception and Sensory Awareness

Another plausible explanation is that Thranduil, being a Sindar, might have a heightened sense of perception. The loss of Erebor would likely have been felt as a collective trauma by the entire population within a wide radius, which a keenly attuned Elf like Thranduil might have sensed instantaneously. This mystical ability of Elves to sense emotions and events remotely has been hinted at in other J. R. R. Tolkien lore.

Challenges of Film Adaptation and Middle-earth Geography

However, it’s important to note that the film's portrayal sometimes diverges from Tolkien’s original text. Peter Jackson, in his adaptation, has taken liberties with the geography of Middle-earth, making distances and travel times appear unrealistic. For instance, Mount Gundabad and Dol Guldur are shown to be much closer to Erebor than the far distances described in the book. This adjustment, while potentially adding to the film's drama, could also create confusion around events and timelines.

Implied Closeness and Added Drama

Despite the aforementioned discrepancies, the movie implies that Laketown is closer to Erebor than in the book. Additionally, Smaug’s journey from the north to Erebor would have necessarily passed over Mirkwood. One can reasonably assume that the inhabitants of Mirkwood, including Wood-elves and birds, would have noticed the massive dragon during its flight. This visual representation of the conflict adds dramatic effect and enhances the tension in the film.

In conclusion, the quick arrival of Thranduil's army in the Hobbit film is a complex issue stemming from the film’s handling of Middle-earth's geography and the unique abilities of its inhabitants. While the adaptation makes some creative choices, these elements contribute to the cinematic experience, highlighting the magical and fantastical nature of Tolkien’s world.
