A battle without a located battlefield
At an uncertain location in southern Iberia, an Umayyad force commanded by Tariq ibn Ziyad defeated the army led by the Visigothic king Roderic. Later Arabic sources place it on 19 July 711; the near-contemporary Chronicle of 754 instead assigns it to 712.
Suggested sites include the Guadalete or Barbate valleys, the former La Janda lagoon, Medina Sidonia and the Chronicle’s unidentified Transductine Mountains. “Guadalete” is a conventional label, not a secure identification.
What the earliest account says
The Chronicle of 754 says the Gothic army fled during the battle and that Roderic was killed, along with rivals who had accompanied him in competition for the kingship.
Tariq’s force was predominantly Berber. One modern reference drawing on Arabic traditions gives 7,000 men including only about 300 Arabs, plus 5,000 reinforcements sent before the battle — roughly 12,000 in all.
The opening of a conquest, not its completion
After the victory Tariq moved east along the Guadalquivir valley toward Écija and Córdoba. The captures of Córdoba, Seville and Toledo were subsequent operations, not events of the battle day.
The 33,000-man Visigothic army in this entry is not securely sourced; early medieval army figures in later narratives are especially unreliable.
The later traditions about searching for Roderic and finding only his horse, saddle, cloak or sandal are likewise not contemporary evidence.

What the sources leave uncertain
- The exact battlefield is unknown. Suggested locations include the Guadalete or Barbate valleys, the former La Janda lagoon, Medina Sidonia, and the Chronicle’s unidentified Transductine Mountains.
- The exact date rests on much later Arabic accounts. The near-contemporary Chronicle of 754 dates the battle to 712, while later Arabic chronology supplies 19 July 711 and other reconstructions give dates later in July.
- Detailed stories about defections by Wittiza’s sons or supporters may preserve the political division mentioned by the Chronicle of 754, but the individuals and choreography come from later traditions.
- Roderic’s death is reported by the Chronicle of 754, but later traditions about finding only his horse, saddle, cloak, or sandal are not contemporary evidence.
