There was no room for the operations of the cavalry.

The artillery also was so injudiciously placed as to be almost entirely useless.

Alonso of Aragon, duke of Villahermosa and illegitimate brother of the king, was present at the siege, and disapproved of the whole arrangement.

He was one of the most able generals of his time, and especially renowned for his skill in battering fortified places.

He recommended that the whole disposition of the camp should be changed, and that several bridges should be thrown across the river.
