Now England might not alone recover her lost possessions in France, but might establish a legitimate claim to the whole.
So it was that an English army was once more upon French soil, and in 1346 Edward, with his toy cannon, had won the battle of Crecy, followed by the siege and capture of Calais, which for two hundred years was to remain an English port--a thorn in the side of France.
A part of the old kingdom of Burgundy, which was called Dauphiny, dropped into the lap of Philip, this first Valois king, during his reign.

The old duke, being without an heir, offered to sell this bit of territory to the King of France upon the condition that it should be kept as the personal possession of the eldest sons of the kings of France.

Thenceforth the title of _Dauphin_ was worn by the heir to the throne, until it became extinct with the son of Louis XVI.

And when the feeble Philip VI.

died in 1350, his son John, the first dauphin, assumed the crown of France.
John, this second Valois king, was an anachronism.
