The siege of Saint-Denis (Late August – 4 October 1435) was the last instance of cooperation between the English and their Burgundian allies in the Hundred Years' War. [1] Saint-Denis, the traditional burial place of the kings of France, was located in the outskirts of English-held Paris, and had been captured by the French a couple of months earlier. The enemy presence there critically endangered the English position in the capital, and, aiming to retake it urgently, the English moved onto the town in August with a handful of Burgundian auxiliaries. The siege was undertaken during the peace congress of Arras, during which no end to the fighting was seen, as both sides struggled to gain ground around and over Paris. The English were victorious at St. Denis after the French garrison surrendered due to lack of external support.


On 21 September 1435, halfway through the siege, the Duke of Burgundy concluded the treaty of Arras with Charles VII of France. The agreement definitely severed the alliance between England and Burgundy. The Burgundians who were fighting alongside the English at Saint-Denis stayed until the end of the siege.

The English did not control of Saint-Denis for long. By the time the town had been recovered, the French had taken Meulan, which blocked the main supply route from Paris to Normandy, further isolating the French capital. The loss of the alliance with Burgundy crippled the English cause militarily, and following the reconciliation between the Armagnacs and Burgundians, military successes by a now-unified and strengthened French party led to the French capture of Saint-Denis in February 1436 and eventually Paris on 13 April 1436, foreshadowing the decline of English fortunes in the war.


The town of Saint-Denis was important not only as a strategic outpost positioned in the very outskirts of Paris, but was also recognized by both sides in the conflict as a symbol of France, [2] as it was the traditional burial place of French monarchs. Near it flows the Croult river, an affluent of the Seine. [3] St. Denis had briefly fallen under French control in 1429, when Joan of Arc arrived, but was retaken soon after. The town and the surrounding region remained under English for the following years, but despite enjoying some military successes in the environs of the French capital during that period, their hold on the area remained tenuous, and the French continued ravaging the Île-de-France right up to the gates of Paris. [4] In late 1434, England's ally Philip the Good, the Duke of Burgundy, began signing a series of truces with the Armagnacs, leaving the English on their own. [5] Moreover, the English were increasingly lacking funds to continue the conflict. By 1435, the English military situation had declined considerably and the French increasingly gained ground in the surroundings of Paris. [2]

On 9 May 1435, an English force was badly defeated at the Battle of Gerberoy. The French did not fail to take advantage of the disrupted English defences, and on the early hours of 1 June, Armagnac troops led by the captains of nearby of Melun and Lagny seized Saint-Denis. [6] [2] Paris was now blockaded, making it difficult to supply the city by river or elsewhere. [2] From their newly established position, the Armagnacs proceeded to afterwards harassed the surroundings of Paris, attacking and killing its inhabitants and ruining plantation fields around the city. [7] The alarmed Parisians sent urgent deputations to John, Duke of Bedford, the English regent of France (then residing at Rouen), and to Louis of Luxembourg, the bishop of Thérouanne and chancellor of France for the English, for the dispatch of sufficient troops to defend the city from the nearby French. [8]

The chancellor summoned 500 French soldiers from Picardy, a Burgundian contingent led by his cousin Jean, the bastard of Saint-Pol. The force was joyfully received in Paris, and, with the aid of Jean de Villiers de L'Isle-Adam, the governor of Paris for the English, commenced to wage war on the nearby Armagnacs. The latter did not relent in face of the resistance and attacked the castle of Orville near Louvres, which belonged to a Burgundian knight. [8] In the meantime, reinforcements were being gathered in England. The English lords Talbot and Willoughby raised a force of 2,500 men and arrived at France in late July 1435. [9] They were joined in France by Lord Scales, [6] who supplied an army of 728 archers and about 50 infantrymen. They joined L'Isle-Adam in Paris, but they had to be redirected to relieve Orville before marching onto St. Denis, leaving the French garrisoned there to freely enjoy its possession, as well as the freedom to roam the environs of Paris, until the siege was finally laid in the last week of August. [10]

In early August, the peace congress of Arras was officially convened [11] with delegations from the Armagnacs, Burgundians, and the English. This did nothing to stop the fighting, as the French and English fought fiercely to gain ground over and near Paris, held only narrowly by the English. [12] Even with peace being discussed, the war around the French capital continued; the Anglo-Burgundian army successfully relieved Orville, and moved to reduce the rest of the area to their obedience. They conducted many successful operations around Paris, recovering many castles and minor strongholds previously taken by the French. [8] In the last week of August, St. Denis was finally invested.

The siege

The besieging Anglo-Burgundian army numbered about 5,000 men, [13] and was led by lords Talbot, Willoughby, Scales, and of L'Isle-Adam. [1] The French garrison, which numbered at least 1,500, [14] was led by marshal Pierre de Rieux. [15] Upon noting the approach of the English, the garrison took their measures to defend the town, remaining alert day and night to be always ready to mount the defence. During the siege, the English were frequently visited by the chancellor Louis of Luxembourg, who urged the besiegers to finish the affair quickly. [15]

The Anglo-Burgundian army carried out their attacks with the same vigor and diligence they had displayed until then throughout the Hundred Years' War. Their cannons caused great damage to the town walls, prompting them to mount a series simultaneous attacks in order to take the place by storm. They gathered a force of 600 men for this purpose. [15] The assault was mounted on 9 September, the day after the Nativity of Mary. [3] Bringing scaling ladders and other instruments of war, the English and Burgundians crossed the moat between them and the fortifications, with the water reaching up their necks, and afterwards began to fearlessly scale the town walls. The defenders mounted an energetic defense; they would lose their lives if the assault was successful. Pierre de Rieux ordered his men at the ramparts not to quit their positions under any circumstance, and had at his disposal a backup force in case any area faced difficulties. [15]

The ferocious assault lasted for 2 hours, with many "gallant acts" being performed by both sides according to the chronicler Monstrelet. The assault was ultimately unsuccessful, and the defenders repulsed the attackers. The deaths of 80 or more attackers [lower-alpha 1] [1] in the ditches or under the walls led the English to evaluate that the attack could not be carried out without heavy casualties, and they sounded a retreat. Despite victorious, the besieged also suffered greatly. They repaired the broken structures, namely the walls and gates, and began looking towards the peace conference at Arras for help from their allies. [16]

On 21 September, the Duke of Burgundy signed the Treaty of Arras with the disputed French king Charles VII, by which he permanently abandoned his English allies. Despite their overlord severing ties with England in the middle of the siege, the Burgundian contingent in the besieging army would stay until the end.

Upon the conclusion of the Congress of Arras, the French constable, Arthur de Richemont, went to Senlis. He was unable to gather a sufficiently powerful force to challenge the English at Saint-Denis, and Rieux, being aware of this, entered into negotiations with the besiegers for the conditional surrender of the garrison. The French were allowed to have their lives spared in return for surrendering the town and returning all prisoners they had made. On 4 October, the defending garrison left Saint-Denis, [6] escorted by 600 cavalry. After 4 months, the town was under English rule once more. [17] Parts the town were razed, with a notable exception of an area which lodged the son-in-law of Simon Morhier, the former English provost of Paris. [18]

Though the English had retaken an important area close to the capital, this was undermined by the French capture of Meulan, to the west of Saint-Denis, at night on 24 September. [19] [20] This blocked the main supply route from Normandy to Paris, [17] and as a consequence food prices in the French capital rose dramatically. The Parisian population was also harassed by the recently released Armagnac garrison of Saint-Denis, who looted, pillaged, and kidnapped around the city. [14]

On 24 September 1435, the dowager queen of France, Isabeau of Bavaria, maternal grandmother of Henry VI of England, had died. The capture of Saint-Denis, the traditional place of burial for French monarchs, allowed her to be buried alongside her deceased husband Charles VI of France. It was still too dangerous to allow the funeral party to travel by land, and so her body was taken by boat down the Seine river. [1]

The defection of Burgundy proved catastrophic and nullified any English gains by the capture of Saint-Denis. Much of English-ruled France began to collapse; Pierre de Rieux, recently relieved from the siege, surprised and captured Dieppe in Normandy on 29 October 1435. [21] Saint-Denis itself was retaken by the French on around February 1436, with an English relief army of around 800 men [22] led by Sir Thomas Beaumont [lower-alpha 2] being almost destroyed. Paris was now blockaded from all sides, and food prices were now at famine levels. The citizens, who were primarily loyal to the Burgundians and not the English, opened the city gates to French forces on 13 April 1436. Among the commanders of the French force was Jean de Villiers, who had fought alongside the English at Saint-Denis only a few months previously.

Siege of Orléans Turning point and French Victory in the Hundred Years War

The siege of Orléans was the watershed of the Hundred Years' War between France and England. It was the French royal army's first major military victory to follow the crushing defeat at the Battle of Agincourt in 1415, and also the first while Joan of Arc was with the army. The siege took place at the pinnacle of English power during the later stages of the war. The city held strategic and symbolic significance to both sides of the conflict. The consensus among contemporaries was that the English regent, John of Lancaster, would have succeeded in realizing his brother the English king Henry V's dream of conquering all of France if Orléans fell. For half a year the English and their French allies appeared to be winning, but the siege collapsed nine days after Joan's arrival.

Dual monarchy of England and France

The dual monarchy of England and France existed during the latter phase of the Hundred Years' War when Charles VII of France and Henry VI of England disputed the succession to the throne of France. It commenced on 21 October 1422 upon the death of King Charles VI of France, who had signed the Treaty of Troyes which gave the French crown to his son-in-law Henry V of England and Henry's heirs. It excluded King Charles's son, the Dauphin Charles, who by right of primogeniture was the heir to the Kingdom of France. Although the Treaty was ratified by the Estates-General of France, the act was a contravention of the French law of succession which decreed that the French crown could not be alienated. Henry VI, son of Henry V, became king of both England and France and was recognized only by the English and Burgundians until 1435 as King Henry II of France. He was crowned King of France on 16 December 1431.
