A siege engine is a type of machine used in warfare to break through the walls of a fortified place, like a castle or city. These engines were essential during medieval times when armies needed to capture strongholds. Common types of siege engines include the catapult, which hurls large stones, and the battering ram, designed to smash through gates. Siege engines were often large and required a team of soldiers to operate. They played a crucial role in battles, allowing attackers to breach defenses and gain control over enemy territory. Their design and effectiveness evolved over time, influencing military tactics throughout history.
