Traditionally, armies laid siege to towns using a combination of strategic planning, blockades, and military technology. Here are the key steps and methods involved in the siege process:
-
Preparation and Intelligence: Before laying siege, armies would gather intelligence about the town's defenses, resources, and the morale of the garrison. This might involve reconnaissance or scouting by advance units.
-
Surrounding the Town: The first step in a siege was to surround the town to prevent supplies and reinforcements from entering. This was achieved by setting up a cordon of troops around the perimeter, often establishing fortified camps and blocking key routes.
-
Blockades: Besieging forces would implement blockades to cut off trade and supplies. This included controlling nearby water sources and roads to hinder the movement of food, weapons, and reinforcements to the besieged town.
-
Building Siege Works: Attackers often constructed siege works, such as trenches and siege towers, to facilitate an assault on the walls. This could involve digging approaches, erecting platforms, and building earthen banks (called "saps") to get closer to the walls.
-
Use of Artillery: With the advent of gunpowder, artillery became a critical element of sieges. Cannons, trebuchets, and other siege engines were used to bombard the fortified walls, aiming to create breaches that troops could exploit.
-
Psychological Tactics: Sieging armies might employ psychological tactics to demoralize the defenders. This could include noise, displays of force, or even negotiations that aimed to sow discord among the besieged.
-
Tunneling: In some cases, besiegers would dig tunnels to undermine the walls of the town, causing sections to collapse. This was a dangerous operation, as defenders might counter with their own tunneling efforts.
-
Assaults: Once the attackers believed the defenses had been worn down, they would launch assaults on the walls or breaches, aiming to capture key points and ultimately take control of the town.
-
Negotiations: Before committing to a full assault, besieging forces might choose to negotiate terms of surrender. Offers of mercy or threats could compel the defenders to capitulate without further bloodshed.
-
Garrisoning: If successful, the conquering forces would then garrison the town, securing control and often beginning a period of reorganization or fortification to defend against possible counterattacks.
Sieges could last for weeks, months, or even years, depending on the strength of the defenses and the will of both the besiegers and the besieged. The process was brutal and often resulted in significant casualties for both sides.
