Abu Yusuf
Abu Yusuf, believing he had sufficient troops to maintain the siege, sent orders for part of his army to march to Lisbon and lay siege to that city too. The orders were misinterpreted and his army, seeing large contingents of men leaving the battle, became confused and started to retreat. Abu Yusuf, in an attempt to rally his troops, was wounded by a crossbow bolt and died on 29 July 1184.
