Reason for it.
The chief reason why the Salic law was applied to the case of the crown of France was not, as it might at first be supposed, because it was thought in those days that women were not qualified to reign, but because, by allowing the crown to descend to the daughters of the king as well as to the sons, there was danger of its passing out of the country. The princes of the royal family usually remained in their own land, and, if they married at all, they married usually foreign princesses, whom they brought home to live with them in their native land. The princesses, on the other hand, when they grew up, were very apt to marry princes of other countries, who took them away to the places where they, the princes, respectively lived. If, now, these princesses were allowed to inherit the crown, and, especially, if the inheritance were allowed to pass through them to their children, cases might occur in which the kingdom of France might descend to some foreign-born prince, the heir, or the actual ruler, perhaps, of some foreign kingdom.
Edward's case.
This was precisely what happened in Edward's case. The Salic law had not then been fully established. Edward maintained that it was not law. He claimed that the crown descended through Isabel to him. The French, on the other hand, insisted on passing him by, and decided that Philip, who, next to him, was the most direct descendant, and whose title came through a line of males, should be king.
Edward raises an army and sets out for France.
In this state of things Edward raised a great army, and set out for France in order to possess himself of the French crown. The war continued many years, in the course of which Edward fitted out several different expeditions into France.
It was in one of these expeditions that he took his son, the Black Prince, then only seventeen years of age, as one of his generals. The prince was a remarkably fine young man, tall and manly in form, and possessed of a degree of maturity of mind above his years. He was affable and unassuming, too, in his manners, and was a great favorite among all the ranks of the army.
Map.
The map on the following page shows the course of the expedition, and the situation of Crecy. The fleet which brought the troops over landed there on a cape a little to the westward of the region shown upon the map. From the place where they landed they marched across the country, as seen by the track upon the map, toward the Seine. They took possession of the towns on the way, and plundered and wasted the country.
