Siege lines

Siege lines are defensive perimeters built around a city or fortress under attack, designed to protect the defending forces and restrict the enemy's access. These lines usually include trenches, walls, or barriers that provide cover and strategic positions for defenders. By establishing siege lines, defenders can hold their position, prevent attackers from advancing, and prepare for potential counterattacks. They serve as a physical and tactical boundary, helping to control movement and sustain the defense during a prolonged siege.
