Enrique de Guzman wished to stop the depredations, and was also motivated to win fame by recapturing the town that his ancestor
Alonso Pérez de Guzmán, founder of his noble house, had first captured in 1309. In 1436 Enrique de Guzman managed to organize a strong force of knights from
Córdoba,
Écija and
Xeres with boats, provisions and soldiers. His son,
Juan de Niebla, was given command of the land army, with 2,000 cavalry and large numbers of infantry. A two-pronged attack was planned. The land forces were to come from the north and take the castle and the heights, while the sea party would land on the Red Sands below the west of the Rock and take the town. ==Siege==
