Tolkien's most disturbing siege tactic was based on real medieval warfare

One of the most unsettling moments in Tolkien's writing occurs during the siege of Minas Tirith, when Mordor's forces shift from conventional assault to a form of psychological warfare that transforms the nature of siege combat entirely.

Instead of continuing their barrage of stones, the orcs begin catapulting the corpses of fallen soldiers directly into the besieged city. This isn't a practical military tactic in any conventional sense. Rather, it's warfare designed to break the spirit and morale of those defending the walls.

The psychology of horror

The bodies serve a singular purpose: to inflict psychological damage. They bring disease into the enclosed space of the city. They spread stench and decay. Most importantly, they instill fear and panic among the defenders, creating the impression that the city is already becoming a graveyard. It's an assault on the mind as much as on the body, designed to make those inside believe that resistance is futile and death is inevitable.

Historical roots in medieval warfare

What makes this detail genuinely disturbing is that Tolkien didn't invent it. Versions of this exact tactic were actually employed during real medieval sieges throughout history. Besieging forces would indeed use catapults and other siege equipment to hurl corpses, diseased animals, or refuse into fortified cities. The goal was identical: to demoralize defenders, spread infection, and create the psychological conviction that the city was already lost.

This historical reality transforms how we read the scene. Suddenly, Middle-earth doesn't feel like pure fantasy. It doesn't feel like the safe realm of imagination. Instead, it becomes horribly plausible, grounded in the genuine horrors that real people once perpetrated against one another. The siege takes on a weight of authenticity that pure invention could never achieve.

Tolkien's genius lay partly in understanding that the most effective dark elements of his world weren't those he had to invent from scratch, but those he could root in the actual cruelty and innovation of human history. By basing this moment on real tactics, he created something that transcends fantasy and touches something far more disturbing: the recognition that humans are capable of terrible things.
