Reviving Tradition: Mongolia’s Winter Migration and the Stakes for the Herd

Since ancient times, the nomadic herders of Mongolia’s Tsakhir Valley have undertaken an annual winter migration to secure feed for their community’s horses and to protect the local pastures. Six years ago, the tradition was abruptly abandoned, but one family is seeking to revive it. Now, members of the local community have come together to decide what to do about their horses. This includes various individuals donating horses and discussing a contract that outlines the risks and dangers associated with the migration. If a horse dies unnaturally, the herdsman must pay the full amount. If it dies from illness or disease, the herdsman is required to provide proof. With mid-autumn ending, the approaching winter is expected to be severe.

Batbold’s Challenge: Upholding Tradition and Safeguarding the Herd

Batbold (Dondongsuren Batbold as himself) is one of the men selected to be a herdsman and will be away on this new job for five months, safeguarding more than a thousand horses. This will also be his first winter herd. Joining him is his best friend, Tsagana (Tsogtgerel Tsagaan-Owgon as himself). When Batbold accepts the role, he assumes the pressure of upholding his ancestors’ tradition.  As Batbold prepares to depart, it becomes evident that members of the community are making last-minute changes to the contracts, and some begin to reconsider their involvement once the discussions and concerns are addressed. When Batbold and his team set out, they find the task ahead is far from easy. The group must discover pastures to keep the herd safe and alive, while remaining alert for any strays. It is equally important that they care for one another and stay vigilant throughout the journey. 

Iron Winter: A Dramatic, Touching Documentary by Kasimir Burgess

Iron Winter is a documentary that is both dramatic and filled with dread, yet it is a deeply touching journey. The film was directed by Kasimir Burgess, whose other works include documentaries such as Franklin (2022) and The Leunig Fragments (2019), as well as drama films like Fell (2014) and others.

A Gripping True Story: Protecting the Herd Through Mongolia’s Deadliest Winter

Personally, I wasn’t aware of this true story, and I found myself deeply compelled early in the film and wanting to know the outcome of this five-month journey. Would Batbold and his fellow crew be successful in protecting the herd of horses? After all, Batbold wasn’t just working through a wild storm; he had to protect the horses against one of the deadliest winters on record.  Audiences will find this film both gripping and emotionally engaging, making it easy to become fully invested in not only the outcome but the entire journey as it unfolds.

Stunning Cinematography and Immersive Landscapes, With Confronting Moments

Visually, this film will be the most rewarding when experienced on the big screen. It is jaw-droppingly beautiful. The cinematography (by Benjamin Bryan) features numerous wide and aerial shots captured from high above, making the horses appear as tiny as ants. The breathtaking landscapes and the raw, untamed nature of the weather are also showcased in full force. The visuals alone are so immersive that audiences will feel as though they’re right there in the storm, sharing in the challenges and sense of dread. That said, some viewers may find certain scenes confronting, particularly those depicting the skinning or butchering of animals. These moments are not for everyone, especially for those who love animals or are faint-hearted. I must admit, one scene involving sheep genuinely took me by surprise and even shocked me.

Wisdom in Conversation: Profound Reflections Amid Mongolia’s Harsh Winter

The dialogue between Batbold and his crew is a highlight of the film. Their conversations often include words of wisdom, the exchange of opinions, and reflections on life’s most profound questions. What happens when a horse dies? A wolf may be an enemy, but humans are worse than wolves. What makes Mother Earth angry? What will life look like after the herd?  Much like the visuals, these moments of dialogue are compelling and deeply engaging to listen to as they unfold.

Iron Winter: A Visually Breathtaking and Thought-Provoking Documentary

Overall, as a documentary, I found Iron Winter highly compelling and visually breathtaking. I was largely unfamiliar with the deadliest Mongolian winter on record, but thanks to Kasimir Burgess, viewers are transported right into the heart of it.  It’s easy to become hooked and invested in Iron Winter, not only for its high stakes and stunning visuals, but also for the real-life discussions of wisdom, opinions, and life’s profound questions, which are both touching and engaging to hear.  For those who consider themselves devoted animal lovers, some scenes may be too graphic or difficult to watch. Nevertheless, there’s no denying that Iron Winter does not shy away from depicting Mongolia’s harsh winter in all its intensity.

Iron Winter (2025) will be Available in Australian Cinemas from March 19th!
