Don Garcia was sent in chains to the castle of Luna, where he eventually died, entreating that he might be buried, with his fetters, in the city of Leon.
[Sidenote: Alfonso at Toledo.] As for Don Alfonso, Dona Urraca pleaded his cause so successfully that he was allowed to retire into a monastery, whence he soon effected his escape and joined the Moors at Toledo.

There he became the companion and ally of Alimaymon, learned all his secrets, and once, during a pretended nap, overheard the Moor state that even Toledo could be taken by the Christians, provided they had the patience to begin a seven-years' siege, and to destroy all the harvests so as to reduce the people to starvation.

The information thus accidentally obtained proved invaluable to Alfonso, as will be seen, and enabled him subsequently to drive the Moors out of the city Toledo.
In the mean while Sancho, not satisfied with his triple kingdom, robbed Dona Elvira of Toro, and began to besiege Dona Urraca in Zamora, which he hoped to take also in spite of it almost impregnable position.
"'See! where on yon cliff Zamora Lifteth up her haughty brow; Walls of strength on high begird her, Duero swift and deep below.'" _Ancient Spanish Ballads_ (Lockhart's tr.).
The king, utterly regardless of the Cid's openly expressed opinion that it was unworthy of a knight to attempt to deprive a woman of her inheritance, now bade him carry a message to Dona Urraca, summoning her to surrender at once.

The hero went reluctantly, but only to be bitterly reproached by Urraca.

She dismissed him after consulting her assembled people, who vowed to die ere they would surrender.
"Then did swear all her brave vassals In Zamora's walls to die, Ere unto the king they'd yield it, And disgrace their chivalry." _Ancient Spanish Ballads_ (Lockhart's tr.).
[Sidenote: Siege of Zamora.] This message so enraged Don Sancho that he banished the Cid.
