Unveiling the Dirty Secrets of Medieval Siege Warfare

Medieval siege warfare was a brutal and sophisticated art of warfare that played a pivotal role in shaping the outcomes of conflicts during the Middle Ages.

Besieging fortified castles and cities required strategic planning, innovative technology, and unwavering determination.

Let’s delve into the secrets of medieval siege warfare, exploring the tactics, weaponry, and engineering marvels used to breach mighty walls and conquer seemingly impregnable fortresses.

1. Siege Engines

Siege engines were large, specialized machines designed to breach castle walls and fortifications. Trebuchets, mangonels, and battering rams were among the most common types of siege engines used to launch projectiles or ram fortified gates.

2. Catapulting Disease

In addition to physical attacks, besiegers employed psychological warfare. They would catapult the bodies of plague victims or animals infected with diseases into the besieged city, spreading fear and pestilence among the defenders.

3. Siege Towers

Siege towers were massive, wheeled structures that allowed attackers to rise above castle walls. Fitted with drawbridges, these towers allowed soldiers to pour into the castle from a commanding height.

4. Mining and Undermining

Besiegers would dig tunnels under castle walls, a tactic known as mining or undermining. Once the tunnel reached the wall’s foundation, wooden supports would be set ablaze, causing the wall to collapse.

5. Sapping

Sapping involved slowly digging trenches toward the castle walls while using wooden shields and screens to protect the diggers. This method allowed attackers to get close to the walls while remaining shielded from defenders.


6. Battering Rams

Battering rams were large wooden beams with metal heads that were used to pound and break through castle gates or weak points in the fortifications.
