There were different techniques and weapons used to attack a medieval castle. The most popular way is to surround the castle by cutting the supplies such as food because during that period, food preservation was an ideal fact. Furthermore, enemies will throw dead bodies to spread dreadful disease into a castle using a catapult.
The most efficient siege weapons were catapults. Afterwards, its concept was used to introduce the use of trebuchets. The enemies used other methods if a fortress cannot be besieged, one of this was to destroy the walls or climb on it. The diggers were sent to dig tunnels beneath a wall and mostly on the corners because this spot exerts more weight against the ground. After the completion of the tunnel, the diggers would go to the surface and put fire on the wood that was set up to make the tunnel collapse therefore affecting the walls by damaging it. For defense, to see where the tunnels built, they would use water and if a tunnel was found, they would made another tunnel to intersect it and a struggle would likely to happen under the castle.
Another effective way to invade a castle is to build gigantic platforms that would take a matter of days to finish. The tall platforms are needed increase the height for the archers on the side of the invaders. Crossbows were introduced in the 15th century and it was effective in killing people that it came to a point that the church forbids the use of it. Even if a knight is using a plate mail, the crossbow could go from one side of a person to the other.
Sometimes it takes a very long time for a castle to surrender. Allied armies would come to help the besieged castle to make the defense much stronger it makes it difficult to successfully invade the castle.
There were some common devices used to conquer a castle. Such as battering ram, pickaxes, diggers, siege, trebuchet and catapults, fire and ladders.
As for the battering ram, it was used to knock over doors and thin walls. It was made of a chopped tree and carried by six to 10 men to knock off a target. To stop projectiles and boiling water, an older battering rams made of roof iron was used.
Pickaxes could make a hole through a wall in a matter of days and were used against older castles with thin walls. Especially if the door of the castle was made of wood, it could be destroyed easily by a pickaxe.
Diggers were used to make the wall or a tower to collapse by digging at the near corner and destroying the tunnel.
Siege was the most common and effective way to attack a castle. Preservation of food at that time was impossible and food was the cause of the defender’s fall. Sometimes, to preserve food, the lord would make the women, children and elders to escape through the tunnel. Unfortunately, if no tunnels existed they would just stay inside the tunnel and hoping for mercy to come. The invaders would then surround the castle and fire projectiles.
Trebuchets and catapults were also common and it would not besiege the castle but it’ll also spread dreadful disease by firing dead bodies; cows, huge rocks, corpses and rotten meat were the projectiles used.
For timber castles, fire was very effective to use but it was nothing against stone castles. In hope of burning anything inside, invaders would shoot thousands of fine arrows.
For smaller castles, ladders were commonly used to climb the wall. Unfortunately, this kind of technique was rarely used because the army on attack would defend themselves by throwing objects or boiling waters at the invaders.
It was difficult to attack a castle. Many were killed on the invaders part rather than the defenders because a castle itself was built mainly for defense therefore protects the residents within. But food would diminish quickly if supplies were intercepted and they would depend on their allies to further defend themselves.
