Guillaume Boitel, was a knight [1] and the faithful companion of the French knight Bertrand Du Guesclin. He was originally sent by king Charles V of France to assist Du Guesclin during the Anglo-French war in Normandy and the Breton War of Succession between Charles de Blois and Jean de Montfort (1363-1364).
Charles V, called "the Wise", was King of France from 1364 to his death, the third from the House of Valois. His reign marked a high point for France during the Hundred Years' War, with his armies recovering much of the territory held by the English, and successfully reversed the military losses of his predecessors.
Normandy is one of the 18 regions of France, roughly referring to the historical Duchy of Normandy.
John V, sometimes numbered as VI, bynamed John the Wise, was Duke of Brittany and Count of Montfort from 1399 to his death. His rule coincided with the height of the Hundred Years' War between England and France. John's reversals in that conflict, as well as in other internal struggles in France, served to strengthen his duchy and to maintain its independence.
He followed Du Guesclin as his vangard chief in Spain, helping Henry II of Castile against his half-brother Peter of Castile, with Breton, French and English warlords such as Hugh Calveley. He conquered Magallón and Briviesca.
Henry II, called Henry of Trastámara or the Fratricide, was the first King of Castile and León from the House of Trastámara. He became king in 1369 by defeating his half-brother, Peter the Cruel, after numerous rebellions and battles. As king he was involved in the Ferdinand Wars and the Hundred Years' War.
Peter, called the Cruel or the Just, was the king of Castile and León from 1350 to 1369. Peter was the last ruler of the main branch of the House of Ivrea.
Sir Hugh Calveley was an English knight and commander, who took part in the Hundred Years' War, gaining fame during the War of the Breton Succession and the Castilian Civil War. He held various military posts in Brittany and Normandy. He should not be confused with his nephew, also Sir Hugh Calveley, who died in June 1393 and was Member of Parliament for Rutland.
He was one of the French chiefs during the Battle of Montiel. In 1369, after the Spanish civil war, he returned to France some months before Du Guesclin, appointed as constable of France in March 1370, for new fights against the troops of king Edward III of England.
The Battle of Montiel was a battle fought in 1369 between Franco-Castilian forces supporting Henry II and an Anglo-Castilian forces supporting Peter.
Edward III was King of England and Lord of Ireland from January 1327 until his death; 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 long reign of 50 years was the second longest in medieval England 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.
