Battle of Poitiers in the context of "Thomas Felton (died 1381)"

Edward III (13 November 1312 – 21 June 1377), also known as Edward of Windsor before his accession, was King of England from January 1327 until his death in 1377. He is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II. Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe. His fifty-year reign is one of the longest in English history, and saw vital developments in legislation and government, in particular the evolution of the English Parliament, as well as the ravages of the Black Death. He outlived his eldest son, Edward the Black Prince, and was succeeded by his grandson, Richard II.

Edward was crowned at age fourteen after his father was deposed by his mother, Isabella of France, and her lover, Roger Mortimer. At the age of seventeen, he led a successful coup d'état against Mortimer, the de facto ruler of England, and began his personal reign. After a successful campaign in Scotland, he declared himself rightful heir to the French throne, starting the Hundred Years' War (1337–1453). Following some initial setbacks, this first phase of the war went exceptionally well for England and would become known as the Edwardian War. Victories at Crécy and Poitiers led to the highly favourable Treaty of Brétigny (1360), in which England made territorial gains, and Edward renounced his claim to the French throne. Edward's later years were marked by foreign policy failure and domestic strife, largely as a result of his decreasing activity and poor health. The second phase of the Hundred Years' War began in 1369, leading to the loss of most of Edward's conquests, save for the Pale of Calais, by 1375.

Charles V (21 January 1338 – 16 September 1380), called the Wise (French: le Sage; Latin: Sapiens), was King of France from 1364 to his death in 1380. His reign marked an early high point for France during the Hundred Years' War as his armies recovered much of the territory held by the English and successfully reversed the military losses of his predecessors.

Charles became regent of France when his father John II was captured by the English at the Battle of Poitiers in 1356. To pay for the defense of the kingdom, Charles raised taxes. As a result, he faced hostility from the nobility, led by Charles the Bad, King of Navarre; the opposition of the French bourgeoisie, which was channeled through the Estates-General led by Étienne Marcel; and with a peasant revolt known as the Jacquerie. Charles overcame all of these rebellions, but in order to liberate his father, he had to conclude the Treaty of Brétigny in 1360, in which he abandoned large portions of south-western France to Edward III of England and agreed to pay a huge ransom.

John II (French: Jean II; 26 April 1319 – 8 April 1364), called John the Good (French: Jean le Bon), was King of France from 1350 until his death in 1364. When he came to power, France faced several disasters: the Black Death, which killed between a third and a half of its population; popular revolts known as Jacqueries; free companies (Grandes Compagnies) of routiers who plundered the country; and English aggression that resulted in catastrophic military losses, including the Battle of Poitiers of 1356, in which John was captured.

While John was a prisoner in London, his son Charles became regent and faced several rebellions, which he overcame. To liberate his father, he concluded the Treaty of Brétigny (1360), by which France lost many territories and paid an enormous ransom. In an exchange of hostages, which included his son Louis I, Duke of Anjou, John was released from captivity to raise funds for his ransom. Upon his return to France, he created the franc to stabilise the currency and tried to get rid of the free companies by sending them to a crusade, but Pope Innocent VI died shortly before their meeting in Avignon. When John was informed that Louis had escaped from captivity, he voluntarily returned to England, where he died in 1364. He was succeeded by his eldest son, Charles V.

The English longbow was a powerful medieval type of bow, about 6 ft (1.8 m) long. While it is debated whether it originated in England or in Wales from the Welsh bow, by the 14th century the longbow was being used by both the English and the Welsh as a weapon of war and for hunting. English longbows were effective against the French during the Hundred Years' War, particularly in the battles of Sluys (1340), Crécy (1346), Poitiers (1356), and Agincourt (1415). They were less successful later on, as longbowmen had their lines broken at the Battle of Verneuil (1424), although the English won a decisive victory there; they were completely routed at the Battle of Patay (1429) when they were charged by the French mounted men-at-arms before they had prepared the terrain and finished defensive arrangements. The Battle of Pontvallain (1370) had also previously shown longbowmen were not particularly effective when not given the time to set up defensive positions.

No English longbows survive from the period when the longbow was dominant (c. 1250–1450), probably because bows became weaker, broke, and were replaced rather than being handed down through generations. More than 130 bows survive from the Renaissance period, however. More than 3,500 arrows and 137 whole longbows were recovered from the Mary Rose, a ship of Henry VIII's navy that sank at Portsmouth in 1545.

Edward of Woodstock (15 June 1330 – 8 June 1376), known as the Black Prince, was the eldest son and heir apparent of King Edward III of England. He died before his father and so his son, Richard II, succeeded to the throne instead. Nevertheless, Edward earned distinction as one of the most successful English commanders during the Hundred Years' War, being regarded by his English contemporaries as a model of chivalry and one of the greatest knights of his age. Edward was made Duke of Cornwall, the first English dukedom, in 1337. He was guardian of the kingdom in his father's absence in 1338, 1340, and 1342. He was created Prince of Wales in 1343 and knighted by his father at La Hougue in 1346.

In 1346, Prince Edward commanded the vanguard at the Battle of Crécy, his father intentionally leaving him to win the battle. He took part in Edward III's 1349 Calais expedition. In 1355, he was appointed the king's lieutenant in Gascony and ordered to lead an army into Aquitaine on a chevauchée, during which he pillaged Avignonet and Castelnaudary, sacked Carcassonne, and plundered Narbonne. In 1356, on another chevauchée, he ravaged Auvergne, Limousin, and Berry but failed to take Bourges. The forces of King John II of France met Edward's armies near the city of Poitiers. After negotiations between the two sides broke down, the Anglo-Gascon forces under Edward routed the French army and captured King John at the Battle of Poitiers.

The first phase (Edwardian phase (1337–1360)) 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.

Edward had been granted the duchy of Aquitaine in 1325, and as Duke of Aquitaine he was a vassal to Philip VI of France. Due to political trouble in England during his early reign as a minor, Edward initially accepted Philip as King of France, but the relationship between the two kings soured in the 1330s when Philip allied with Edward's enemy, King David II of Scotland. Edward in turn provided refuge to Robert III of Artois, a French fugitive. When Edward refused to obey Philip's demands for the expulsion of Robert from England, Philip confiscated the Duchy of Aquitaine. This precipitated war and, in 1340, Edward declared himself king of France. Edward III and his son Edward the Black Prince, led their armies on a largely successful campaign across France with notable victories at Auberoche (1345), Crécy (1346), Calais (1347), and La Roche-Derrien (1347). Hostilities were paused until the mid-1350s for the deprivations of the Black Death. Then war continued, and the English were victorious at the Battle of Poitiers (1356) where the French king, John II, was captured and held for ransom. The Truce of Bordeaux was signed in 1357 and was followed by two treaties in London in 1358 and 1359.

Geoffroi de Charny (c. 1306 – 19 September 1356) was the third son of Jean de Charny, the lord of Charny (then a major Burgundian fortress), and Marguerite de Joinville, daughter of Jean de Joinville, the biographer and close friend of France's King Louis IX. A renowned knight who fought on the French side during the early years of the Hundred Years' War, Charny wrote a semi-autobiographical poem, The Book of Geoffroi de Charny, and a set of questions on chivalric matters for the short-lived Company of the Star, France's counterpart to England's Order of the Garter. Although a prose treatise called the Book of Chivalry has also long been accredited to him, recent findings indicate this to have been more likely by his son of the same name, Geoffroi II de Charny, who died in 1398. Charny is also widely associated with the first known showings of the Shroud of Turin, though there are now doubts that he was responsible for these.

He took part in a successful crusading expedition to Smyrna in 1344 and shortly after his return from this King Philip VI appointed him a royal councillor and bearer of the Oriflamme, the sacred battle-standard of France. This role, one in which he continued under King Jean II, made its holder an automatic target for enemy forces on a battlefield, and it was thus that he met his end during the closing moments of the Battle of Poitiers on 19 September 1356.
