The castle walls were still standing. No great breach had opened, and the defenders were not yet starving. Yet inside Thun L'Eveque, something far harder to fight had taken hold: the smell of a dead horse decomposing among the crowded buildings.
In 1340, sieges could drag on for months or even years. Armies brought thousands of horses, cattle, and pack animals, and disease, exhaustion, and enemy attacks created a grim problem outside every fortified settlement: what could be done with the dead?
At Thun L'Eveque, the answer was loaded into a trebuchet. Operators placed a rotting horse carcass into the sling and launched it high over the walls, turning a machine built to smash stone into a weapon aimed directly at the defenders' senses.
The carcass did not need to destroy masonry. Its purpose was to make life inside the castle unbearable. The stench spread through rooms and courtyards, spoiled food, ruined sleep, and made every breath a reminder that the besieging army could contaminate the space within.
This tactic was not limited to horses. Commanders could throw cattle, pigs, sheep, and sometimes human corpses. During the Mongol siege of Caffa in 1346, plague victims were reportedly catapulted into the city, although historians still debate whether this helped carry the Black Death into Europe.
A fortress could resist fire, ladders, and stones. It was far harder to defend against decay itself. In medieval warfare, surrender sometimes began not when the walls fell, but when the air inside them became impossible to breathe.
