Throughout the Crusades, both Christian and Muslim forces used a variety of military tactics, including sieges, open battles, naval engagements, and guerrilla warfare. The battles often involved heavy cavalry charges, archery, and infantry formations. The Crusades also saw the construction of numerous castles and fortifications by both sides to defend their territories and control strategic locations.
