In the days following Hasan's death, the Sultan of Morocco sultan had moved his forces to the coastline of his territory. He had done this before Berengar and his forces discovered the truth about Hasan's demise. Because of Al-Andlus' defeat in Morocco, the Iberian peninsula was now defended by a paltry sum of German forces. Most of these men were spread across the entire region and needed time to regroup. Said planned to take advantage of this lackluster defense by mounting an invasion of Granada.
Said's plan was simple, land his forces into Granada before the German reinforcements could arrive, and seize the southernmost portion of Iberia, connecting it to his sultanate. As for the Catholics in the North, he figured they would be happy to be free from the control of their current Muslim masters, and he had no desire to rule over them.
