The lustre of this great success increased the king’s authority among his allies, who assembled their forces with expedition, and joined the English army. Edward marched to the frontiers of France at the head of above one hundred thousand men, consisting chiefly of foreigners, a more numerous army than either before or since has ever been commanded by any king of England.[***] At the same time the Flemings, to the number of fifty thousand men, marched out under the command of Robert of Artois, and laid siege to St. Omer; but this tumultuary army, composed entirely of tradesmen unexperienced in war, was routed by a sally of the garrison, and notwithstanding the abilities of their leader, was thrown into such a panic, that they were instantly dispersed, and never more appeared in the field. The enterprises of Edward, though not attended with so inglorious an issue, proved equally vain and fruitless. The king of France had assembled an army more numerous than the English; was accompanied by all the chief nobility of his kingdom; was attended by many foreign princes, and even by three monarchs, the kings of Bohemia, Scotland, and Navarre:[****] yet he still adhered to the prudent resolution of putting nothing to hazard; and after throwing strong garrisons into all the frontier towns, he retired backwards, persuaded that the enemy, having wasted their force in some tedious and unsuccessful enterprise, would afford him an easy victory. * Froissard, liv. i. chap. 51.
