Ferdinand’s conquest of Navarre during England’s war with France (1512)

Ferdinand’s conquest of Navarre during England’s war with France (1512) turned an English expedition intended to win glory and territory into cover for Ferdinand II of Aragon’s advance into Navarre. The English troops were not merely left unsupported: their presence at Fuenterrabia was the diversion that kept France, the rival kingdom, occupied while Ferdinand moved against his own objective. Katherine of Aragon understood the design before its full consequences became undeniable, and the expedition’s collapse revealed how completely Ferdinand had used England’s soldiers for his own ends.

Alliance and Preparation

The campaign began with the English fleet sailing to join Ferdinand II of Aragon’s war against France. Henry VIII was drawn to the prospect of fighting in Europe, against the French king and alongside powerful Christian rulers. The expedition sailed in a display of royal confidence, its ships flying the banners of England’s great houses and carrying what the narrative describes as the best-equipped and finest-arrayed force to leave England in years.

Katherine of Aragon had overseen the practical work behind that appearance: provisioning the ships, stocking the armories, and equipping the soldiers. She had learned from her mother’s wartime example that battles depended on reliable supply. She therefore expected the carefully prepared force to defend the Pope, defeat France, and secure rich gains for England. Ferdinand’s assurances of a quick victory strengthened those expectations, despite the Privy Council’s concern that England might be drawn into another prolonged war.

The Diversion at Fuenterrabia

Once the English troops arrived, they were not sent into battle. Their commanders reported pointless inaction, exercises on the border, and sightings of French forces—who could also see the English—without receiving orders to engage. Katherine of Aragon knew her father as a commander who kept men occupied and moving. Their idleness, and the sickness and disorder that followed, persuaded her that the inactivity had been planned rather than caused by mere incompetence.

She concluded that Ferdinand II of Aragon was using the English army as an inactive counterweight. The French, alarmed by a force on their flank, had to guard against the English presence and could not attack Ferdinand. Meanwhile, Ferdinand marched at the head of his own troops into the unprotected kingdom of Navarre. The English held the French in place while Ferdinand took what he had long desired, at no expense or danger to himself.

Retreat and Recognition

The English army eventually returned in December in what the narrative calls dishonored tatters. Its commander had despaired of receiving either orders or reinforcements from Ferdinand II of Aragon. The troops were hungry and weary, faced mutiny, and had lost two thousand men to illness. They had gone out amid banners and high hopes; they came back in disgrace, without having been given the battle their preparations had anticipated.

When Henry VIII came to Katherine of Aragon in anger and near tears, letters from his father-in-law had further wounded him by complaining about the English allies’ conduct. He felt that he had lost face in both Spain and France and could not understand how so bold a departure had ended in such disorder. Katherine comforted him, insisting that the English soldiers’ courage had not been tested and found wanting. Her reassurance did not erase her knowledge of the deception: she had suspected it from the summer, when the army arrived and was not deployed, and now recognized that her father had misled them.

Strategic and Political Significance

The episode separates the expedition’s public purpose from its actual strategic effect. England had supplied ships, arms, provisions, and men for a campaign expected to bring it military honor and territorial gains. In practice, the English force constrained French action long enough to give Ferdinand II of Aragon freedom to pursue Navarre. The diversion achieved its purpose for Ferdinand, while leaving England to bear the human and political consequences of an army kept idle and unsupported.

For Katherine of Aragon, the campaign also made the alliance’s imbalance personal. Her careful preparation had helped send a formidable force abroad, but her knowledge of her father’s habits led her to read its inaction as evidence of a concealed plan. The failed English expedition thus marks not simply a military disappointment but a moment of recognition: Ferdinand’s confident promises had served his own strategy, while Henry VIII and the English troops were left to absorb the humiliation and loss.
