Attacking a castle was no easy feat for any army. Castles were built to be strong and defend against invaders. However, attackers came up with clever ways to break through these defenses. One of the lesser-known but fascinating techniques was called undermining, or sapping. This involved digging tunnels beneath the castle walls or towers. The attackers would use wooden beams to support the tunnel and then set fire to kindling placed around the area. The fire would cause the tunnel to collapse, bringing down part of the castle structure and allowing the attackers to rush in and surprise the defenders.
As castles became more advanced and harder to breach using traditional methods, many armies turned to sapping. Even though some castles had strong foundations set in solid rock, there was no foolproof way to stop sapping. This tactic was used throughout medieval times and even beyond. Sapping has a long history, dating back over 4,000 years. It was used during the time of Caesar and continued to be a strategy in warfare up to the two World Wars. With the introduction of gunpowder, sapping became even more destructive and effective.
One of the earliest recorded uses of sapping was during the siege of Dura Europos in 256 CE. The Sasanian forces tried to undermine a Roman stronghold. They faced challenges like hard stone layers, but the Romans were aware of their tactics and countered by digging their own tunnels. Although the Sasanians didn’t succeed, this event highlighted the strategic importance of sapping.
Sapping was a major strategy during the medieval period. A famous example is the 1215 Siege of Rochester Castle during the First Barons’ War. King John used sapping to attack the southeast tower, successfully collapsing part of the keep. Another instance occurred in 1216 at the siege of Dover Castle, where Prince Louis attempted to undermine the castle but was ultimately stopped.
The tactic of sapping continued to evolve over time. During the siege of Bedford Castle in 1224, King Henry III used miners to breach the inner defenses successfully. Sapping was also used in later conflicts, including trench warfare in World War I and the Vietnam War, where tunneling was effectively employed by both sides.
While undermining and sapping may not be as common as they were in ancient and medieval times, they are still used in certain parts of the world today. This tactic shows how creativity and strategy in warfare have evolved over centuries, adapting to new challenges and technologies.
Gather materials like cardboard, paper, and glue to construct a model castle. Pay attention to the defensive features such as walls and towers. This will help you understand why castles were difficult to attack and how sapping could be a useful tactic.
Divide into groups and simulate a medieval siege. One group will defend the castle, while the other will plan an attack using sapping. Discuss strategies and decide how to counteract each other’s moves. This will give you insight into the challenges faced by both attackers and defenders.
Choose a historical siege where sapping was used, such as the Siege of Rochester Castle. Research the event and present your findings to the class. Focus on the tactics used and the outcome of the siege. This will deepen your understanding of sapping’s role in history.
Work in pairs to create a timeline that highlights key events in the history of sapping. Include ancient uses, medieval examples, and modern-day relevance. This activity will help you see the evolution of this tactic over time.
Imagine you are a castle architect in medieval times. Design a defensive strategy to protect against sapping. Consider features like deeper foundations or counter-tunnels. Share your design with the class and discuss its potential effectiveness.

Attacking a castle was a challenging task for any army, but invaders developed various methods to breach castle defenses. One lesser-known technique was undermining, or sapping, where attackers would tunnel beneath the walls or towers, using wooden supports to shore up the space. They would place kindling around the area and ignite it to collapse part of the structure, allowing them to pour through and surprise those inside.
As castle designs became more sophisticated, breaking through walls using conventional methods became increasingly difficult, leading many forces to turn to sapping. Despite challenges like strong foundations set into bedrock, there was no way to completely prevent sapping, and it continued to be used throughout medieval times and beyond. The use of sapping can be traced back to antiquity and persisted into the two World Wars. After medieval times, while its use decreased, it remained a viable tactic, especially with the introduction of gunpowder, which made sapping more destructive and effective.
One of the earliest examples of sapping dates back over 4,000 years, with evidence of soldiers undermining city walls during the time of Caesar. At the siege of Dura Europos in 256 CE, the Sasanian forces attempted to sap a Roman-held stronghold. They dug towards the walls but encountered hard stone layers. The Romans, aware of the Sasanian tactics, also undermined to counter their efforts. Although the Sasanian attempt ultimately failed, it demonstrated the strategic importance of sapping.
Sapping became a major strategy during the medieval period, with notable instances such as the 1215 Siege of Rochester Castle during the First Barons’ War. King John used sapping to attack the southeast tower, successfully exposing and collapsing part of the keep. Another example occurred in 1216 at the siege of Dover Castle, where Prince Louis attempted undermining but was ultimately blocked from taking the castle.
Sapping continued to evolve, with significant examples during the siege of Bedford Castle in 1224, where King Henry III successfully used miners to breach the inner defenses. The tactic persisted into later conflicts, including trench warfare in World War I and the Vietnam War, where tunneling was employed effectively by both sides.
While undermining and sapping may not hold the same power as in ancient and medieval times, they remain tactics used in certain parts of the world today.
