The Counterattack of Sancho Ramírez and the Uncertain Outcome (1067 CE)

Between August and September 1067, Sancho Ramírez of Aragon, allied with Sancho IV of Navarre, launches a counteroffensive against Castile, pushing back against Sancho II of Castile’s incursions into Navarre and La Rioja.

However, historical tradition is divided over who emerged victorious:

• The Chronicle of San Juan de la Peña records a Navarrese and Aragonese victory, claiming they routed Castilian forces at Viana.
• The Primera Crónica General, in contrast, attributes victory to Sancho II of Castile, portraying him as triumphant in battle.

The conflicting accounts reflect the political biases of later chroniclers and the uncertainty surrounding the outcome of this phase of the War of the Three Sanchos. Regardless of the victor, the war underscores the intense rivalry between the Christian kingdoms as they competed for dominance in northern Iberia.
