John I of Armagnac (French: Jean d’Armagnac; 1311 16 May 1373), son of Bernard VI and Cecilia Rodez, was Count of Armagnac from 1319 to 1373. In addition to Armagnac he controlled territory in Quercy, Rouergue and Gévaudan. He was the count who initiated the 14th century expansion of the county.


Hundred Years War

In summer 1337, with the outbreak of the Hundred Years War, he provided a contingent of 6,000 men for the campaign of Raoul I of Eu, Constable of France, in Gascony.

In July 1338, he attended a general conference at La Réole, but before achieving anything of note, John and his fellow captain-general in the south, Gaston III, Count of Foix, were called north to help counter the expected invasion of Northern France by King Edward III of England. As this threat grew weaker the French offensive in the south was resumed with the siege of Penne-d'Agenais in November by John of Bohemia and the Count of Foix. John provided 1,200 men for this siege, which ended with the surrender of the town, though not the castle.

Through these early years of the war the Count of Foix had conducted a series of independent campaigns which allowed him to expand his personal territory into the Adour valley and the Landes. This expansion brought him into conflict with Armagnac. Just after his return from the north at the end of 1339 John attacked Miramont-Sensacq, a small town he laid claim to, but which was situated in territory dominated by the Count of Foix. This started a short but violent private war, ended by the town taken into royal custody.

This quarrel caused John to reconsider his allegiance to the French Crown. When he in May 1340 again went to join King Philip VI of France's northern army, he left Bernard Ezi IV, Lord of Albret with documents stating terms under which terms he would be willing to do homage to Edward III. As compensation for the territory he expected to lose once he switched allegiance Armagnac demanded several towns held by the King of France, chief among them Montréal, Mézin and Condom. Of these the English only succeeded in taking and holding Mézin. The negotiations therefore came to an end and John remained a vassal of Philip VI.

In the north the situation had improved for the English with their naval victory in the Battle of Sluys. Edward III's next step was an attack on Saint-Omer by his Flemish allies led by Robert III of Artois. However Robert III failed completely in masking his intentions. This allowed Philip VI to dispatch John of Armagnac to reinforce the garrison already present there under Eudes IV, Duke of Burgundy. On 26 July what begun as an unauthorized attack on the enemy lines by some French knights developed into a major battle as the Duke of Burgundy decided to sally forth in strength. During the Battle of Saint-Omer the Count of Armagnac with his retinue of 300 heavy cavalry succeeded in breaking the Flemish left and then in the following pursuit causing several thousand casualties. Faced with the loss of the bulk of his army Robert of Artois was forced to retreat from the city in disorder.

Meanwhile, Edward III had with his own army laid siege to the city of Tournai. The siege dragged out and in September Philip VI marched to confront him. The result was not battle, but negotiations in which John of Armagnac took part as one of five French plenipotentiaries. The negotiations resulted in a truce concluded on 24 September. The lull in the fighting, except for an interlude in 1342, was to last until 1345.

In August 1345 Armagnac was laying siege to the Anglo-Gascon garrison at Monchamp outside Condom when Henry of Gosmont, Earl of Lancaster arrived in Bordeaux. Derby's opened his campaign with the capture of the garrison town of Bergerac by storm. This caused major shock to at the French court as no significant English army was expected in the south. Armagnac helped shore up the French position by gathering some of the survivors and retreating to Périgueux. Lancaster moved to surround Périgueux, but did not have the strength to capture the city and in October he was forced to withdraw with the arrival of a force commanded by Louis of Poitiers, Count of Valentinois.

In September 1346, following the French defeat at the Battle of Crécy and the beginning of the English Siege of Calais, Armagnac was appointed royal lieutenant in the south-west. However, due to the overall worsening French situation he was left with few troops and little money. He was therefore unable to stop Lancaster neither from consolidating English gains in the south nor from launching a major raid into Poitou.

Marriages & Children

He played a key role in French national affairs during the early 15th century, particularly in the struggles to rule the country for the mentally ill King Charles VI, his cousin, and the Hundred Years' War with England. A rash, ruthless and unscrupulous politician, John murdered the King's brother, the Duke of Orléans, in an attempt to gain control of the government, which led to the eruption of the Armagnac–Burgundian Civil War in France and in turn culminated in his own assassination in 1419.

The County of Foix was an independent medieval fief in southern France, and later a province of France, whose territory corresponded roughly the eastern part of the modern département of Ariège.

A chevauchée was a raiding method of medieval warfare for weakening the enemy, primarily by burning and pillaging enemy territory in order to reduce the productivity of a region, as opposed to siege warfare or wars of conquest. The use of the chevauchée declined at the end of the 14th century as the focus of warfare turned to sieges. Its legacy eventually led to the scorched earth strategies used in modern warfare.

Hundred Years War (1337–1360) First phase of the Hundred Years War

The first phase of the Hundred Years' War between France and England lasted from 1337 to 1360. It is sometimes referred to as the Edwardian War because it was initiated by King Edward III of England, who claimed the French throne in defiance of King Philip VI of France. The dynastic conflict was caused by disputes over the French feudal sovereignty over Aquitaine and the English claims over the French royal title. The Kingdom of England and its allies dominated this phase of the war.

The Battle of Auberoche was fought on 21 October 1345 during the Gascon campaign of 1345 between an Anglo-Gascon force of 1,200 men under Henry, Earl of Derby, and a French army of 7,000 commanded by Louis of Poitiers. It was fought at the village of Auberoche near Périgueux in northern Aquitaine. At the time, Gascony was a territory of the English Crown and the "English" army included a large proportion of native Gascons. The battle resulted in a heavy defeat for the French, who suffered very high casualties, with their leaders killed or captured.

Battle of Saint-Omer Major field battle of the Hundred Years War

The Battle of Saint-Omer, fought on 26 July 1340, was a major engagement which occurred in the early stages of the Hundred Years' War. It was a part of King Edward III's summer campaign against France launched from Flanders. The campaign was initiated in the aftermath of the Battle of Sluys but turned out to be far less successful than he hoped. At Saint-Omer, in an unexpected turn of events, the heavily outnumbered French men-at-arms, tasked with defending the city and awaiting for reinforcements, defeated the Anglo-Flemish forces on their own. The Allies suffered heavy losses and the French captured their camp intact, taking many warhorses and carts, all the tents, huge quantities of stores and most of the Flemish standards. Edward's campaign of 1340 had begun badly. On the bright side, the loss of several thousand men was bearable, as the survivors, which included most of the precious English longbowmen, eventually rejoined him at Tournai. The defeat had serious strategic consequences. It exposed southern Flanders to the wrath of Philip VI and enabled the French to concentrate their forces against the main army of the coalition in the Tournaisis.

The County of Fézensac was an 8th-century creation on the north-eastern fringes of the Duchy of Gascony following Charlemagne's policy of feudalisation and Frankish colonisation. The move was aimed at offsetting and undermining the authority of the duke of Gascony Lupo II after the setback suffered by the Franks at the Battle of Roncevaux in 778 and failure to restrain the Basques. That advance clearly displeased the Basques, with these policies sparking a stir on the banks of the Garonne.

House of Valois-Burgundy

The House of Valois-Burgundy, or the Younger House of Burgundy, was a noble French family deriving from the royal House of Valois. It is distinct from the Capetian House of Burgundy, descendants of King Robert II of France, though both houses stem from the Capetian dynasty. They ruled the Duchy of Burgundy from 1363 to 1482 and later came to rule vast lands including Artois, Flanders, Luxembourg, Hainault, the county palatine of Burgundy (Franche-Comté), and other lands through marriage, forming what is now known as the Burgundian State.

John IV was involved in the intrigues related to the Hundred Years' War and in conflicts against the King of France.

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.

Gascon campaign of 1345 Military campaign during the Hundred Years War

The Gascon campaign of 1345 was conducted by Henry, Earl of Derby, as part of the Hundred Years' War. The whirlwind campaign took place between August and November 1345 in Gascony, an English-controlled territory in south-west France. Derby, commanding an Anglo-Gascon force, oversaw the first successful English land campaign of the war. He twice defeated large French armies in battle, taking many noble and knightly prisoners. They were ransomed by their captors, greatly enriching Derby and his soldiers in the process. Following this campaign, morale and prestige swung England's way in the border region between English-occupied Gascony and French-ruled territory, providing an influx of taxes and recruits for the English armies. As a result, France's ability to raise tax money and troops from the region was much reduced.
