Saintonge War
In English history, the ‘Hundred Years’ War’ refers to the 116-year period between 1337 – 1453. In some French accounts, that period of conflict is referred to as the ‘Second Hundred Years’ War’, the first embracing the period of upheaval following the change in the balance of power between the French and English thrones from 1159 to 1259 after Henry II of England married Eleanor of Aquitaine gaining many French territories in the process and achieving territorial superiority over the French Kingdom, until the Treaty of Paris (1259), in which the opposite became true. This period saw many conflicts and battles between the two kingdoms such as the Anglo-French War (1202–1214) or the Battle of Bouvines.
Truce of Leulinghem
In 1369 the French government repudiated the 1360 Treaty of Brétigny, resuming the Hundred Years' War between the kingdom of France and the kingdom of England and their various allies. The war originated over the King of England's status as both a French duke and also an English king, creating conflicting interests in many of his actions. The French had declared the English duchy in southwestern France forfeit, beginning the war. The English won the first phase, and the treaty granted the English possession of the duchy as a fief independent of France. During the ensuing decade of peace, the French government strengthened and determined to establish control over the duchy. For nearly two decades, the French pursued a military policy of avoiding direct battle with the English armies and wearing them down by attrition. Although the English won a few victories, eventually almost all of their gains from the earlier phases of the war were lost, including all of the Duchy of Aquitaine except for a narrow coastal strip from Bordeaux to the border of Navarre.
