Battle of Viadangos

The fortified southern city of Zamora and the royal castle at Ceia north of Sahagún, both in León, were offered to Henry on top of his Portuguese possessions, as were some territories in Castile.

[2] Henry appears to have demanded more than his assistance to her cause could command, however, for Urraca soon entered into secret negotiations with her husband; before leaving she left orders with her men to surrender Palencia to him.

The Crónicas anónimas de Sahagún attribute this to the ambitions of Theresa, Urraca's half-sister, Henry's wife, who coveted a queenship and had joined her husband at Palencia.

[2] From there the trio split: Henry turned to Zamora to possess it, while Urraca and Theresa went first to Sahagún before the queen moved on to her capital, León.

[10] The place where Urraca was staying and where Diego brought Alfonso was probably Orcellón in the diocese of Orense in a district known as Castela, not in Castile, as the text seems to be saying.

[11][12] After delivering Alfonso to Urraca, Diego returned to Astorga to retrieve the wounded and others and lead them back to Santiago de Compostela, from whence they had set out.
