Siege of Fuenterrabía (1523–1524)

At the beginning of October 1521 the castle of Behovia was taken by the troops commanded by the French Admiral Guillermo Goufier, Lord of Bonnivet, with hardly any casualties, since little resistance was offered. He next surrounded the fortress of Fuenterrabía on October 6, taking it twelve days later, after three assaults by Navarrese and Gascon volunteers, among which nearly a thousand casualties occurred. Diego de Vera, warden of the plaza, surrendered on October 18.

The Lord of Bonnivent established a garrison with 3,000 men, who were 2,000 Gascons and 1,000 Navarrese under the orders of Jacques D'Aillon, Lord of Luda, who remained as mayor of the square "in the name of the King of Navarre". For this reason, the flag of Navarre was waving throughout the siege, despite the intention of the French to raise their flag.

Charles V requested the arbitration of King Henry VIII of England so that he intervened before Francis I and required this position. Knowledge of these conversations by the Navarrese was decisive for the replacement of the garrison months later.

Beltrán de la Cueva y Toledo, duke of Alburquerque, was appointed, on May 23, 1522, new captain general of Gipuzkoa, although he had already held the position previously, which with a significant increase in troops from different places, between 3000 and 4,000 German lanskenetes, and soldiers recruited in Castile, Navarre, Aragón, Vizcaya, La Rioja and Álava.

Faced with the difficulties in defending the castle of Behovia, the French army decided to abandon it. The withdrawal was carried out correctly, taking the cannons, weapons and provisions. Later, different explosive charges were arranged to destroy its walls, but its fuses were extinguished by the Castilian troops under the command of Captain Ochoa Sanz de Asua, who took the castle.

Two days later, the Battle of Mount Aldabe or San Marcial took place.

In July 1522, it was decided to surrender the fortress due to starvation. After ten months without being supplied, deaths from starvation began to occur. French troops came who, after crossing the Bidasoa, made the imperial troops flee, being able to supply the square and renew the garrison. For this reason Beltrán de la Cueva was dismissed, who was replaced by Íñigo Fernández de Velasco, Constable of Castile.

The naval control of the fortress allowed the supply to be maintained. Throughout the siege, the red flag of Navarre flew in the fortress, despite the fact that the French tried to impose theirs.

In the winter of 1523-1524 a great offensive was organized by Emperor Charles V against Francis I, with the intention of occupying Toulouse, Lower Navarre, Bayonne and Fuenterrabia. This campaign failed after 24 days with the loss of a quarter of the army due to desertions and disease. These troops regrouped and joined the bulk of the army surrounding Fuenterrabía.

On 2 February 1524, the bombardment of the fortress began and negotiations for surrender began. On 27 February the French abandoned the fortress, leaving only Navarrese soldiers, the most notable being Pedro de Navarre, son of Marshal Pedro de Navarra who had been killed in strange circumstances, presumably assassinated, in the Simancas prison in 1522.

On 29 February 1524, pardon was granted to the imprisoned Navarrese, with the condition that within two months they surrendered and gave an oath and loyalty to Charles V. The fortress was surrendered on 29 April.
