Battle of Allenburg (St. George's Night)

The Battle of Allenburg was a major battle in the Ingrian War which pitted a force of Teutonic Knights, aided by papally-sanctioned Crusaders, against a Livonian-Swedish force. The battle is today commonly used to mark the end of the era of heavy cavalry dominance, as the overwhelmingly cavalry Teutonic force suffered a devastating defeat at the hands of a smaller, less experienced infantry army.
