The Battle of Poitiers was fought on 19 September 1356 between a French army commanded by King John II and an Anglo-Gascon force under Edward, the Black Prince, during the Hundred Years' War. It took place in western France, 5 miles (8 km) south of Poitiers, when approximately 14,000 to 16,000 French attacked a strong defensive position held by 6,000 Anglo-Gascons.
The Treaty of Brétigny was a treaty, drafted on 8 May 1360 and ratified on 24 October 1360, between Kings Edward III of England and John II of France. In retrospect, it is seen as having marked the end of the first phase of the Hundred Years' War (1337–1453) as well as the height of English power on the European continent.
Henry of Grosmont, Duke of Lancaster was an English statesman, diplomat, soldier, and Christian writer. The owner of Bolingbroke Castle in Lincolnshire, Grosmont was a member of the House of Plantagenet, which was ruling over England at that time. He was the wealthiest and most powerful peer of the realm.
The first phase of the Hundred Years' War between England and France 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, and Edward's sovereignty over Aquitaine was confirmed in the Treaty of Brétigny (1360), although he renounced his claim to the French throne.
The Battle of Blanchetaque was fought on 24 August 1346 between an English army under King Edward III and a French force commanded by Godemar du Fay. The battle was part of the Crécy campaign, which took place during the early stages of the Hundred Years' War. After landing in the Cotentin Peninsula on 12 July, the English army had burnt a path of destruction through some of the richest lands in France to within 20 miles (32 km) of Paris, sacking a number of towns on the way. The English then marched north, hoping to link up with an allied Flemish army which had invaded from Flanders. They were outmanoeuvred by the French king, Philip VI, who garrisoned all of the bridges and fords over the River Somme and followed the English with his own field army. The area had previously been stripped of food stocks by the French, and the English were essentially trapped.
The Battle of Lunalonge was fought in the summer of 1349 between a French force numbering approximately 1,500 men and an Anglo-Gascon force of some 500 men, during the first phase of the Hundred Years' War. The location of the battle is thought to have been modern Limalonges in Deux-Sèvres. The outnumbered Anglo-Gascons, commanded by Thomas Coke, gained the upper hand during the day, but had to withdraw on foot during the night because the French, under Jean de Lille, had captured their horses. The French lost approximately 300 killed and an unknown but large number captured, including their leader.
The Battle of Caen was an assault conducted on 26 July 1346 by forces from the Kingdom of England, led by King Edward III, on the French-held town of Caen and Normandy as a part of the Hundred Years' War.
The Hundred Years' War was a conflict between the kingdoms of England and France and a civil war in France during the Late Middle Ages. It emerged from feudal disputes over the Duchy of Aquitaine and was triggered by a claim to the French throne made by Edward III of England. The war grew into a broader military, economic, and political struggle involving factions from across Western Europe, fuelled by emerging nationalism on both sides. The periodisation of the war typically charts it as taking place over 116 years. However, it was an intermittent conflict which was frequently interrupted by external factors, such as the Black Death, and several years of truces.
The Battle of Pontvallain, part of the Hundred Years' War, took place in the Sarthe region of north-west France on 4 December 1370, when a French army under Bertrand du Guesclin heavily defeated an English force which had broken away from an army commanded by Sir Robert Knolles. The French numbered 5,200 men, and the English force was approximately the same size.
The Battle of Bergerac was fought between Anglo-Gascon and French forces at the town of Bergerac, Gascony, in August 1345 during the Hundred Years' War. In early 1345 Edward III of England decided to launch a major attack on the French from the north, while sending smaller forces to Brittany and Gascony, the latter being both economically important to the English war effort and the proximate cause of the war. The French focused on the threat to northern France, leaving comparatively small forces in the south-west.
The Battle of Calais took place in 1350 when an English force defeated an unsuspecting French army which was attempting to take the city. Despite a truce being in effect the French commander Geoffrey de Charny had planned to take the city by subterfuge, and bribed Amerigo of Pavia, an Italian officer of the city garrison, to open a gate for them. The English king, Edward III, became aware of the plot and personally led his household knights and the Calais garrison in a surprise counter-attack. The French were routed by this smaller force, with significant losses and all their leaders captured or killed.
The Reims campaign took place during the Hundred Years' War. It occurred after the French de facto government rejected the terms of the Treaty of London and consequently Edward III of England organised and commanded an expeditionary army to gain by force what he had failed to win by diplomacy. On 28 October 1359 Edward landed at Calais, and advanced to Reims, where he hoped to be crowned king of France. The strenuous resistance of the citizens frustrated this scheme, and Edward marched into Burgundy, and then he made his way back towards Paris. Failing in an attack on the capital, he was glad to conclude, on 8 May 1360, preliminaries of peace at Brétigny, near Chartres. This treaty, less onerous to France than that of London, took its final form when Edward and John ratified the treaty in Calais on 9 October 1360. By it Edward renounced his claim to France in return for Aquitaine and other French territories in full sovereignty.
The Black Prince's chevauchée of 1356 was a large-scale mounted raid by an Anglo-Gascon force under the command of Edward, the Black Prince, between 4 August and 2 October 1356 as a part of the Hundred Years' War. The war had broken out in 1337, but a truce and the ravages of the Black Death had restricted the extent of the fighting since 1347. In 1355 the French king, John II, determined to resume full-scale war. That autumn, while Edward III of England threatened northern France, his son, Edward of Woodstock, later known as the Black Prince, carried out a devastating mounted raid, or chevauchée: an Anglo-Gascon army marched from the English possession of Gascony 675 miles (1,086 km) to Narbonne and back. The French refused battle, despite suffering enormous economic damage.
Lancaster's chevauchée of 1356 in Normandy was an English offensive directed by Henry, Duke of Lancaster, in northern France during 1356, as a part of the Hundred Years' War. The offensive took the form of a large mounted raid – a chevauchée – and lasted from 22 June to 13 July. During its final week the English were pursued by a much larger French army under King John II that failed to force them to battle.
The siege of Guînes took place from May to July 1352, when a French army under Geoffrey de Charny unsuccessfully attempted to recapture the French castle at Guînes which had been seized by the English the previous January. The siege was part of the Hundred Years' War and took place during the uneasy and oft-broken truce of Calais.
The Treaty of Guînes was a draft settlement to end the Hundred Years' War, negotiated between England and France and signed at Guînes on 6 April 1354. The war had broken out in 1337 and was further aggravated in 1340 when the English king, Edward III, claimed the French throne. The war went badly for France: the French army was heavily defeated at the Battle of Crécy, and the French town of Calais was besieged and captured. With both sides exhausted, a truce was agreed that, despite being only fitfully observed, was repeatedly renewed.
Edward III's chevauchée of 1355 took place when King Edward III of England led an army into Picardy in the hope of provoking the French into a battle. Edward's son The Black Prince had begun a chevauchée on 5 October with an Anglo-Gascon force from Bordeaux heading towards Narbonne.
Lancaster's Loire campaign was the march south from Brittany in August 1356 by an English army led by Henry, Duke of Lancaster. He was attempting to join the army of Edward, the Black Prince, near Tours. The French had broken the bridges over the River Loire and Lancaster was forced to turn back, returning to Brittany in September.
The siege of Breteuil was the investment of the Norman town of Breteuil, held by partisans of Charles II, King of Navarre, by French forces. It lasted from April to about 20 August 1356. It was interrupted on 5 July when a small English army commanded by Henry, Earl of Lancaster relieved and resupplied it. The French king, John II, attempted to bring Lancaster to battle with the much larger French royal army, but Lancaster marched away and the attempt failed. John then renewed the siege of Breteuil.
English offensives in 1345–1347, during the Hundred Years' War, resulted in repeated defeats of the French, the loss or devastation of much French territory and the capture by the English of the port of Calais. The war had broken out in 1337 and flared up in 1340 when the king of England, Edward III, laid claim to the French crown and campaigned in northern France. There was then a lull in the major hostilities, although much small-scale fighting continued.
