Henry V had no real basis for his claim to the French crown. Edward III had gone to war because France was encroaching upon Guienne and aiding Scotland, and because he was encouraged by the Flemish towns. Henry V, on the other hand, was merely anxious to make himself and his house popular by deeds of valor. Nevertheless his very first victory, the battle of Agincourt, was as brilliant as that of Crécy or Poitiers. Once more the English bowmen slaughtered great numbers of French knights. The English then proceeded to conquer Normandy and march upon Paris. [Sidenote: Treaty of Troyes, 1420.] Burgundians and Orleanists were upon the point of forgetting their animosities in their common fear of the English, when the duke of Burgundy, as he was kneeling to kiss the hand of his future sovereign, the Dauphin,[189] was treacherously attacked and killed by a band of his enemies. His son, the new duke of Burgundy, Philip the Good, immediately joined the English against the Dauphin, whom he believed to be responsible for his father's murder. Henry then forced the French to sign the treaty of Troyes (1420), which provided that he was to become king of France upon the death of the mad Charles VI. [Sidenote: Henry VI recognized as king in northern France.] Both Henry V and Charles VI died two years later. Henry V's son, Henry VI, was but nine months old; nevertheless according to the terms of the treaty of Troyes he succeeded to the throne in France as well as in England. The child was recognized only in a portion of northern France. Through the ability of his uncle, the duke of Bedford, his interests were defended with such good effect that the English succeeded in a few years in conquering all of France north of the Loire, although the south continued to be held by Charles VII, the son of Charles VI. [Sidenote: Joan of Arc.] Charles VII had not yet been crowned and so was still called the Dauphin even by his supporters. Weak and indolent, he did nothing to stem the tide of English victories or restore the courage and arouse the patriotism of his distressed subjects. This great task was reserved for a young peasant girl from a remote village on the eastern border of France. To her family and her companions Joan of Arc seemed only "a good girl, simple and pleasant in her ways," but she brooded much over the disasters that had overtaken her country, and a "great pity on the fair realm of France" filled her heart. She saw visions and heard voices that bade her go forth to the help of the king and lead him to Rheims to be crowned. [Sidenote: Relief of Orleans by Joan, 1429.]
