The siege of Acre was the first significant counterattack by Guy of Jerusalem against Saladin, Sultan of Egypt and Syria. This pivotal siege formed part of what later became known as the Third Crusade. The siege lasted from August 1189 until July 1191, at which time the city's coastal position meant the attacking Latin forces were unable to fully capture the city and Saladin was unable to fully relieve it, with both sides receiving supplies and resources by sea. It concluded as a key victory for the Crusaders and a serious setback for Saladin's ambition to destroy the Crusader states.
