The Ayyubid force then moved south to Frankish Oultrejordain where they were joined by a contingent from Egypt.

A part of their force began investing in the Crusader fortress of Kerak, while the other raided the Frankish lordship.

[1] The Ayyubid forces probably did not have any artillery so they changed their tactics by unleashing a loose blockade to starve the garrison.

[2] The garrison of Kerak posed little threat to the Muslims and the crushing defeat at the Battle of Hattin meant that no relief force would arrive soon, allowing the Ayyubids to take a relaxed approach to their siege and wait for the Crusaders to surrender.

In November 1188, after a year and a half months, the garrison surrendered and was allowed free passage.
