the reckless brother and covets the "Asturias of Santander", Old Castile, Briviesca and Rioja. Ferdinand visited his ill brother, but suspecting him fled. García visited an ill Ferdinand then, wishing to dispel his suspicions, but was locked in Cea. Upon escaping, he took his troops and some Moors into Castile. In Atapuerca the peace talks failed. Two traitor soldiers (one of them, Sancho Fortún), wounded him lethally. Ferdinand conceded the transport of the corpse to Nájera, took Briviesca, Montes de Oca and part of Rioja. The border of Navarre was set by the Ebro, and the new king Sancho IV of Navarre became Ferdinand's vassal. El Cid? Some sources mention El Cid as one of the battlers, but being born on 1043 or 1048 he would be too young. Later history In 1940 a commemorative inscription was carved on a 6,000-year-old menhir at the site. Since 1996, the people of Atapuerca and neighbour towns reenact the battle on the last or previous Sunday of August.
