Arthur III, more commonly known as Arthur de Richemont, was briefly Duke of Brittany from 1457 until his death. He is noted primarily, however, for his role as a leading military commander during the Hundred Years' War. Although Richemont briefly sided with the English once, he otherwise remained firmly committed to the House of Valois. He fought alongside Joan of Arc, and was appointed Constable of France. His military and administrative reforms in the French state were an important factor in assuring the final defeat of the English in the Hundred Years' War.
The Battle of Formigny, fought on 15 April 1450, was a major battle of the Hundred Years' War between England and France. A decisive French victory that destroyed the last significant English field army in Normandy, it paved the way for the capture of their remaining strongholds.
Jean Bureau was a French artillery commander active primarily during the later years of the Hundred Years' War. Along with his brother, Gaspard, he is credited with making French artillery the most effective in the world. As Master Gunner of Artillery in the armies of Charles VII, Bureau acquired a reputation as an effective artillery officer during the Normandy campaign (1449–1450), when his bombardments helped capture the towns of Rouen, Harfleur, and Honfleur, and aided in the French victory at Formigny. Bureau commanded the victorious French army at the decisive Battle of Castillon in 1453.
The Lancastrian War was the third and final phase of the Hundred Years' War between England and France. It lasted from 1415, when Henry V of England invaded Normandy, to 1453, when the English were definitively defeated in Aquitaine. It followed a long period of peace from the end of the Caroline War in 1389. The phase is named after the House of Lancaster, the ruling house of the Kingdom of England, to which Henry V belonged.
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.
Events from the 1410s in England.
The Hundred Years' War was a series of armed conflicts fought between the kingdoms of England and 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, fueled 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.
Edmund Beaufort, 2nd Duke of Somerset, 4th Earl of Somerset, 1st Earl of Dorset, 1st Marquess of Dorset styled 1st Count of Mortain, KG, was an English nobleman and an important figure during the Hundred Years' War. His rivalry with Richard, Duke of York, was a leading cause of the Wars of the Roses.

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.
