Siege of Acre (1189–91)

The Siege of Acre was one of the first confrontations of the Third Crusade, lasting from August 28, 1189 until July 12, 1191, and the first time in history that the King of Jerusalem was compelled to personally see to the defence of the Holy Land. It was also the deadliest event of the whole period of the Crusades for the Christian ruling class of the east.^[4] Nevertheless, it was a key victory for the Crusaders and a serious defeat for Saladin, who had hoped to destroy the whole of the Crusader kingdom.
