The battle of Uclés of 1108 Historical milestone · Uclés, La Mancha Conquense, Cuenca Battle fought on 29 May 1108 at Uclés (Cuenca) between the Christian troops of Alfonso VI of León and the Almoravids of Ali ibn Yusuf, who had already defeated Alfonso VI earlier at Sagrajas (1086) and at Consuegra (1097), where the Cid's son died, and who in 1102 had conquered Valencia. After the death of Yusuf ibn Tashfin in 1106, his son Ali decided to attack the kingdom of León via Uclés, a strategic point since Celtiberian and Roman times, and put his brother Tamim ibn Yusuf in command of the army. The Almoravid troops defeated the Castilian army at the gates of the town; among the roughly three thousand dead was Sancho Alfónsez, Alfonso VI's only male son, which left Castile without a direct heir. 1108 Photo: Tribiwiki (CC BY-SA 4.0) What to see and do in Uclés
