The Castle of Cea was very strong, was well garrisoned, and provided with provisions sufficient to bear a long siege; for these reasons Don Fernando believed that an attempt to take it would result in a loss both of time and men. However, as such obstacles were only incentives to the courage of the Cid, for by that name Rodrigo was now known, he believed that the Christian army should not pass on farther without giving a fresh proof of its power by destroying that first bulwark of the Moslems.

"Sire," said Rodrigo to the king, "I am about to ask a favour of you, which I trust you will grant."

"Speak, Rodrigo," replied Don Fernando, "for you already know how desirous I am to gratify you."

"The favour I ask of you is, that you will permit me, this very day, to plant the Christian standard with my own hands on the walls of the Castle of Cea."

"O good Cid, who is there but must love you as the best cavalier in the world!" exclaimed Don Fernando, clasping him to his breast. "With a hundred knights like you, I would undertake to drive the Moors, not alone from Portugal, but from all Spain. It is not idle talk when the people say that you were born in a lucky hour! I applaud your valour, Rodrigo; my heart swells and rejoices when I hear you thus speak; but you know that the enterprise which you desire to undertake is very difficult."

"Sire, it is in difficult and useful enterprises that glory is to be found. In this castle have taken refuge those who have pillaged and laid waste a considerable portion of your states, and they must not remain unpunished. Pardon me if I speak with more heat than is seemly before my lord and king, but Rodrigo Diaz would rather break his sword into fragments than be within a few bow-shots of the Moors and not come to close quarters with them. Let them but see that we do not take into consideration whether their walls are strong or weak, and the terror that will seize on them shall serve us better than our weapons. The same feeling is widespread amongst those under my command, who desire to be the first to prove to the infidels that there are no Moors capable of resisting Castilian arms."

"Well, then, Rodrigo, let us attack and conquer this fortress," replied Don Fernando, full of hope and joy. "Then let us hasten on to Viseo and other strongholds, and let us not return to Castile till we have freed Portugal completely from the Moslem domination."

Preparations were then immediately made for the siege of the castle. In a few hours it was attacked and defended with extreme obstinacy. The Moors discharged clouds of projectiles from the walls, causing terrible carnage amongst the besiegers. The battering-rams, which the latter worked unweariedly, did not move a stone, for the walls of Cea were extremely solid. The Cid, and those under his command, who fought in the most advanced position, were burning with impatience, seeing that the time for dashing at the fortress was delayed so long.

"To the assault! To the assault!" cried the Cid, full of ardour and courage.

"To the assault!" cried all who were fighting by his side.
