He ordered that short-lived meeting of the states-general about which we have no information left us, save that it voted the principle that "no talliage could be imposed on the people if urgent necessity or evident utility should not require it, and unless by concession of the Estates." Philip, as chief of feudal society, rather than of the nation which was forming itself little by little around the lords, convoked at Amiens all his vassals, great and small, laic or cleric, placing all his strength in their co-operation, and not caring at all to associate the country itself in the affairs of his government.

Edward, on the contrary, whilst equipping his fleet and amassing treasure at the expense of the Jews and Lombard usurers, was assembling his Parliament, talking to it "of this important and costly war," for which he obtained large subsidies, and accepting without making any difficulty the vote of the Commons' House, which expressed a desire "to consult their constituents upon this subject, and begged him to summon an early Parliament, to which there should be elected, in each county, two knights taken from among the best land-owners of their counties." The king set out for the Continent; the Parliament met and considered the exigencies of the war by land and sea, in Scotland and in France; traders, ship-owners, and mariners were called and examined; and the forces determined to be necessary were voted.
Edward took the field, pillaging, burning, and ravaging, "destroying all the country for twelve or fourteen leagues to extent," as he himself said in a letter to the Archbishop of Canterbury.

When he set foot on French territory, Count William of Hainault, his brother-in-law, and up to that time his ally, came to him and said that "he would ride with him no farther, for that his presence was prayed and required by his uncle, the King of France to whom he bore no hate, and whom he would go and serve in his own kingdom, as he had served King Edward on the territory of the emperor, whose vicar he was; "and Edward wished him 'God speed!'" Such was the binding nature of feudal ties that the same lord held himself bound to pass from one camp to another, according as he found himself upon the domains of one or the other of his suzerains in a war one against the other.

Edward continued his march towards St.Quentin, where Philip had at last arrived with his allies, the Kings of Bohemia, Navarre, and Scotland, "after delays which had given rise to great scandal and murmurs throughout the whole kingdom." The two armies, with a strength, according to Froissart, of a hundred thousand men on the French side, and forty-four thousand on the English, were soon facing one another, near Buironfosse, a large burgh of Picardy.

A herald came from the English camp to tell the King of France that the King of England "demanded of him battle.
