Siege of Lisbon

Timeline

1. 1147Porto · PortugalAbout 164 ships carrying over ten thousand northern European crusaders put in at Porto after storms. Afonso I, offering a share of spoils and ransoms, persuaded the allied fleet to divert and besiege Lisbon instead of sailing directly to the Holy Land.
2. 1147Lisbon · PortugalThe allies erected mangonels to bombard the walls, and the garrison sortied to burn some of the engines. As the siege turned into a prolonged blockade, the crusaders finally breached a section of the wall, and the tide turned sharply.
3. 1147Lisbon · PortugalThe garrison negotiated on October 21 and was allowed to withdraw safely; four days later the gates opened and Lisbon fell into Christian hands. After the war, some crusaders stayed and were absorbed into the Portuguese nobility.
