Siege of La Rochelle (1627–1628)

The Siege of La Rochelle (1627–1628) is both the central military enterprise of Cardinal Richelieu’s statecraft and the historical pressure that gathers the novel’s scattered adventures into one national crisis. Presented as the campaign against the last great Huguenot refuge, it is also a contest between France and England, a struggle over the Atlantic gateway of La Rochelle, and an arena in which private love, political vengeance, dynastic suspicion, and military ambition become inseparable.

Causes and Political Background

The siege arose from the religious and constitutional position of La Rochelle. Of the cities granted to the Huguenots by Henry IV as places of safety, it was the last that remained. Richelieu therefore treated its destruction as necessary to remove the final stronghold of Calvinism, which the narrative associates with both internal revolt and foreign intervention. La Rochelle was not merely a rebellious city: it had become the focus of competing confessional and international ambitions.

Its importance was enlarged by the movement of foreign support. Spaniards, Englishmen, Italian malcontents, adventurers, and soldiers of fortune from many countries gathered under the Protestant standard, forming a loose association whose influence extended across Europe. The city’s harbor was also the last port in the French kingdom open to the English. Closing it would weaken England’s access to the French coast and complete, in Richelieu’s political imagination, a work associated with Joan of Arc and the Duc de Guise.

The campaign therefore carried several kinds of stakes at once. Richelieu sought the destruction of a religious and political center; England sought to preserve an ally and maintain access to the port; and the Duke of Buckingham pursued a private vengeance beneath the language of national honor. Because Buckingham could not enter France as an ambassador, he wished to enter as a conqueror. The narrative’s sharpest irony is that the apparent struggle between two powerful kingdoms is repeatedly driven by the desire of two powerful men to win a favorable glance from Anne of Austria.

The Opening Campaign and d'Artagnan’s Place

The first major advantage belonged to Buckingham. He appeared unexpectedly before the Isle of Ré with ninety vessels and nearly twenty thousand men, surprised the Comte de Toiras, who commanded for the king, and secured a landing after a bloody conflict. The Comte de Toiras withdrew with his garrison into the citadel of Saint-Martin, while a hundred men were placed in the smaller fort of La Prée. The English occupation of the island made the danger immediate and accelerated Richelieu’s preparations for the larger operation against La Rochelle.

Richelieu sent Monsieur to direct the first operations and ordered every available troop toward the theater of war. d'Artagnan formed part of this vanguard. His involvement places his personal advancement inside a military hierarchy whose movements are determined by royal illness, command arrangements, and the rivalry of senior officers. When Louis XIII became ill with fever after his Bed of Justice and halted at Villeroy, the Musketeers halted with him. d'Artagnan, still serving in the Guards and not yet admitted to the Musketeers, was consequently separated from Athos, Porthos, and Aramis and left among men with whom he had formed few friendships.

He nevertheless reached the camp before La Rochelle on September 10, 1627. The military situation remained unresolved: Buckingham’s English forces still held the Isle of Ré and continued, unsuccessfully, to besiege the citadel of Saint-Martin and the fort of La Prée, while hostilities around La Rochelle had begun near a fort constructed by the Duc d'Angoulême. The siege thus appears not as a single assault but as a network of positions, detachments, rival commands, and delayed convergences in which d'Artagnan’s movement through the plot follows the larger mobilization of the kingdom.

Operations, Logistics, and the English Defeat

Once the French command structure had been organized, the army turned first to driving the English from the island. The moment favored France. The English troops suffered from poor provisions, living on salt meat and bad biscuit, and many became ill. Rough seas destroyed small vessels along the coast, leaving the shore between l'Aiguillon and the trenches covered at every tide with the wreckage of pinnacles, roberges, and feluccas. Even without a decisive French advance, these conditions threatened to make Buckingham’s position untenable.

Reports that the enemy was preparing another assault led Louis XIII to order decisive action. The French expedition succeeded to the king’s astonishment and Richelieu’s glory. The English were driven back step by step, defeated in repeated encounters, and beaten during the passage of the Isle of Loie. They were forced to re-embark, leaving approximately two thousand men on the battlefield, including five colonels, three lieutenant colonels, two hundred and fifty captains, and twenty gentlemen of rank. The French also captured four cannon and sixty flags, which Claude de St. Simon carried to Paris and displayed with ceremony in the arches of Notre Dame. Te Deums were sung in the camp and afterward throughout France.

This victory removed the immediate English threat and left Richelieu free to continue the siege. Yet the triumph was only temporary in political terms. An envoy of Buckingham named Montague was captured, and evidence was obtained of a league directed against France involving the German Empire, Spain, England, and Lorraine. Papers found in Buckingham’s abandoned lodging appeared to confirm the alliance and, in Richelieu’s account, seriously compromised Mme. de Chevreuse and therefore the queen. Military success consequently intensified the political danger surrounding Anne of Austria rather than ending it.

Royal Institutions and the Logic of Siege

The campaign exposes the institutional tensions governing Louis XIII’s France. The king and Richelieu maintained rival bodies of Musketeers, each seeking celebrated swordsmen from the provinces of France and from abroad. Although the two rulers publicly condemned duels and brawls, they secretly encouraged their men to quarrel and took pleasure or disappointment in the outcomes. The siege belongs to the same political world: military force is organized through competing loyalties, while personal honor and court rivalry are redirected into state violence.

The king’s authority also operated through contradictory rules. He insisted that an edict remained an edict and that fighting was forbidden, yet he arranged to receive d'Artagnan and the three Musketeers privately by the back staircase after their encounter with five of the cardinal’s Guardsmen. In another confrontation, the king maintained that a case should be sent before the judges, while M. de Treville argued that even a blameless life could not protect a man from infamy and persecution. These moments illuminate the siege’s wider political structure: formal law, royal favor, military necessity, and ministerial power coexist without becoming a single consistent system.

Richelieu’s control of the campaign likewise depended on the distribution of command. Bassompierre and Schomberg, both marshals of France, claimed the right to command beneath the king, but Richelieu distrusted Bassompierre’s Protestant sympathies and supported the Duc d'Angoulême as lieutenant general. Separate commands were assigned to prevent the marshals from abandoning the army. Monsieur watched Bassompierre; Louis XIII watched the Duc d'Angoulême; and Richelieu watched Schomberg. The siege was therefore also a system of surveillance among commanders, in which military organization reproduced the political rivalries of the court.

Consequences and Narrative Significance

The siege’s consequences extend beyond the battlefield. La Rochelle remains invested even after the English have been expelled, and the city’s endurance becomes a test of the French army’s patience and the cardinal’s authority. The dyke prevents vessels from entering the besieged city, but the blockade may still last a long time. The mayor suppresses an attempted mutiny by hanging the mutineers, after which the inhabitants resolve to die of hunger rather than surrender. Military engineering, food supply, discipline, and morale thus become as important as swordplay.

For the characters, the campaign creates the conditions under which private missions become dangerous acts of international politics. Buckingham’s expedition is connected to Anne of Austria’s peril; papers found after his withdrawal threaten Mme. de Chevreuse and the queen; and d'Artagnan’s service with the advancing forces makes him part of the king’s war before he has achieved the status he desires. The wider war also allows Milady to be directed toward England at the moment when Buckingham’s preparations appear most formidable, turning the same international network of ships, ports, officers, and intelligence into a field for individual conspiracy.

The Siege of La Rochelle (1627–1628) therefore functions as more than historical scenery. It is the novel’s great mechanism of convergence. Religious division becomes state policy, state policy becomes military logistics, military logistics create opportunities for espionage, and espionage returns to the intimate rivalries of the court. The campaign’s apparent public purpose is the consolidation of royal France; its narrative effect is to reveal how that consolidation depends upon unstable alliances, exceptional decisions, private motives, and the continuing collision between the king’s authority and Richelieu’s power.
