The Navarrese Counteroffensive and English Withdrawal (October 1512)

By mid-October 1512, King John III of Navarre, determined to reclaim his kingdom from Ferdinand II of Aragon's forces, assembled a 15,000-strong army composed of:

  • Navarrese loyalists
  • Gascon mercenaries from Béarn and Guyenne
  • Landsknechts, elite German infantry

With this force, John III launched a counteroffensive, advancing into Gipuzkoa and the Navarrese heartland, seeking to retake key fortresses and push back Castilian occupation.


Navarrese Three-Pronged Invasion

The counterattack was structured into three military columns, each with distinct objectives:

  1. Siege of Hondarribia and Donostia (San Sebastián)

    • The first column laid siege to Hondarribia and Donostia, major Castilian-held towns in Gipuzkoa.
    • The Navarrese also occupied smaller surrounding towns to divert Castilian forces from reinforcing Pamplona, which remained under siege.
  2. Central Assault on Castilian Positions in Navarre

    • The main column advanced into the heartland of Navarre, directly challenging Castilian control over Pamplona and surrounding fortresses.
  3. Diversionary Raids in Eastern Navarre

    • A third column targeted weaker Castilian outposts, harassing supply lines and disrupting Spanish logistics.

The English Abandon Ferdinand II and Withdraw

  • The English, originally aligned with Ferdinand II in the Holy League, had become frustrated with his shifting political priorities and lack of clear military coordination.
  • By late 1512, the English decided to leave the war, returning home after raiding and sacking several towns and villages, including Errenteria.
  • Their departure weakened Castilian military strength, further encouraging the Navarrese resistance.

Significance of the Counterattack

  • The Navarrese offensive demonstrated that John III was still capable of resisting Ferdinand’s occupation.
  • The loss of English support weakened Castile’s military advantage, making Ferdinand’s hold on Navarre more vulnerable.
  • The siege of Hondarribia and Donostia placed pressure on Castilian forces in Gipuzkoa, forcing them to split their army between defending northern and southern fronts.

Conclusion: Navarre’s Fight for Survival Continues

  • Although John III’s counteroffensive created serious challenges for Castile, Navarre remained heavily outmatched in resources and manpower.
  • The war was not yet decided, and the fate of Navarre’s independence still hung in the balance.
  • The events of late 1512 marked the final phase of the struggle for Navarre, setting the stage for the last major battles of the campaign.
