Some ships that were approaching the city with aid turned back in the face of the siege engines, either because of the danger of stone projectiles or because the heads of the massacred were launched at them. The city itself, or that part of it under crusader control, was completely destroyed.[3][9][7][4] The siege had lasted nearly fifteen days. Some knights managed to escape on galleys,[5] including the castellan, Íñigo de Alfaro.[11]
