Counterweight Trebuchet

Timeline

1. 1191Acre · Northern DistrictIn the final phase of the 1191 Siege of Acre, the crusaders deployed large counterweight trebuchets such as 'Bad Neighbor' and 'Bad Cousin' to bombard the walls, while the Ayyubid defenders returned fire with their own trebuchets; the exchange of engines became the iconic siege scene of the battle.
2. 1192–1200Eastern Mediterranean · LevantAfter the Battle of Acre, counterweight trebuchet technology spread further along the eastern Mediterranean coast; both the Crusader states and the Ayyubid regime maintained siege-engine workshops, and from the late 1190s to 1200 the equipment remained standard for attacks on and defense of Levantine fortresses.
