The capture of Goizueta marked the beginning of a protracted military campaign by Spanish forces to conquer the Kingdom of Navarre, a strategically vital territory located in the Pyrenees region. Commanded by Captain Diego de Salazar, Spanish troops took Goizueta amidst resistance from local forces. The action was part of a broader effort by King Ferdinand II of Aragon, who sought to unify the Iberian Peninsula under Spanish rule. By securing Goizueta, the Spanish established a foothold in Navarre, enabling further advances into the heart of the kingdom. The townspeople and the local nobility were taken by surprise, as the well-planned assault was swift and strategic, leading to minimal initial confrontation. Following the capture, Spanish forces continued to push deeper into Navarre, resulting in further engagements with both local defenders and allied troops from territories resisting Spanish rule. This event was pivotal, as it underscored the militaristic strategies employed by the Spanish monarchy during this period and the lengths they were willing to go to expand their territory and influence.
