preparation for a summer of campaigning. His army included eight Leonese counts and Castilian magnates (los ochos condes of legend), who, with their heavy cavalry retinues, probably counted for a fifth of the total heavy cavalry resources of the crown. Including Sanchos' personal guard, the number of Christian troops was probably about 400 knights and an equal number of squires and grooms: about 1,200 men total. A contingent of townsmen from Calatañazor, Alcalá, and Toledo, led by their alcaldes, numbering probably 750, mostly infantry but some light cavalry, joined the main force before the battle. Including 300 or so men involved in the baggage train, Bernard Reilly estimates a total number of 2,300 Christian troops, while the Arabic sources mention 3,000 Christian heads piled in front of Uclés to terrorise the citizens. Battle joined The Christians arrived near Uclés and set up camp on 28 May. Tamim assembled his force with the Córdobans under Muhammad ibn Abi Ranq in front, his own Granadans behind them; the Valencians and Murcians made up the flanks. Battle was joined the next day with a Christian cavalry charge. Though initially successful against the Córdobans, the charging Christians were quickly surrounded while engaging the Granadans and the main force retreated to their camp. The Murcians and Valencians meanwhile attacked the baggage. The infantry was dispersed; the cavalry was caught in their own camp and slaughtered. Sancho, his horse killed and with a small force of seven of his own men, escaped and fled towards Belinchón, but was killed by his Muslim subjects, who took advantage of the battle to revolt. The only count to escape was Álvar Fáñez, who led a large body of horse north to organise the defence of the upper Tagus. In the aftermath the Muslims lured the garrison of the Uclés into sallying from the alcázar and defeated them. The Almoravids followed up their success by taking the castles of Huete and Ocaña, and a few small others. The identity of the seven dead counts must be patched together from various sources. Crónica Najerense records the death of García Ordóñez, the count of Nájera. Lucas de Tuy records his death also, as well as that of the heir and of Martín Laíñez. Probably Martín's son, Gómez Martínez, also perished. Based on their sudden disappearance from contemporary documents, Reilly suggests that Fernando Díaz, the greatest magnate of Asturias, and the Castilian magnates
