Saladin imposed a crushing defeat on the united army of the Kingdom of Jerusalem in the Battle of Hattin on 4 July 1187. Isabella's husband was captured on the battlefield. Before long, Saladin's troops seized most towns and fortresses of the Kingdom of Jerusalem: Tiberias fell soon after the battle, Acre on 9 July, Beirut before 6 August, and Jerusalem on 2 October. Tyre was an exception, holding out for months under the command of Conrad of Montferrat who had come to the Holy Land from Italy a few weeks after the battle.
