Siege Weapons
🪨
Trebuchet
Counterweight catapult — the most powerful siege engine. Could hurl 150kg stones over 300m. Edward I used "Warwolf" (built from 30 wagons of timber) against Stirling Castle in 1304.
Range: 150–300m | Payload: up to 150kg
🏹
Ballista
Giant crossbow firing bolts or stones. Accurate at 500m. Used defensively on castle walls and offensively in siege towers. Could pin a man to a wall from 300 meters.
Range: 300–500m | Payload: 30–80kg bolts
🔥
Mangonel
Torsion-powered catapult using twisted ropes for energy. Less powerful than the trebuchet but faster to reload. Often flung diseased corpses over walls to spread plague.
Range: 50–150m | Payload: 60kg
🗼
Siege Tower
Wooden tower rolled up to walls, enabling attackers to cross onto the battlements. Needed perfectly flat ground. Defenders poured boiling oil, rocks, and fire down onto them.
Height: matches wall | Crew: 20–200
⛏️
Battering Ram
Log (often with iron ram head) suspended in a wheeled shelter. Teams of men swung it into gates. Defenders lowered padded beams to absorb blows or used hooks to catch the ram.
Impact: 8–12 tons | Team: 30–60 men
🌉
Mining / Sappers
Tunneled under walls, propped with timber, then burned the props. The collapse brought down towers and walls. At Rochester (1215), King John burned pig fat in the tunnels.

Military Orders
Knights Templar
Founded 1119 — Dissolved 1312

Knights Hospitaller
Founded c. 1099 — Still active today
Originally a hospital order in Jerusalem. Evolved into a military force. After losing the Holy Land, held Rhodes (1310–1522) then Malta (1530–1798) as sovereign territory. Today: the Sovereign Military Order of Malta.
Teutonic Knights

Order of Santiago
