A siege hook is basically a big metal tool used to pull down walls, buildings or gates during battles. It looks like a giant hook with a long pole attached to it. It's used by soldiers or armies during ancient times, especially during a siege or attack on a castle or fortress. The hook is used to grab onto the walls or gates, and the soldiers would then pull on it with horses or ropes to break down the barrier. It's like when you use a fishing rod to catch a fish, but instead of a fish, people use the siege hook to catch walls or gates. Siege hooks were very important during battles as they helped to break down obstacles and make it easier for the soldiers to take over the castle or fortress. That’s basically what a siege hook is - a giant metal tool to help break down walls, gates and fortifications during a battle.
