However that may be, the communal forces evidently filled an important place in the king's army at Bouvines, and maintained it brilliantly.

So soon as Philip had placed himself at the head of the first line of his troops, "the men of Soissons," says William the Breton, who was present at the battle, "being impatient and inflamed by the words of Bishop Guerin, let out their horses at the full speed of their legs, and attacked the enemy.

But the Flemish knights prick not forward to the encounter, indignant that the first charge against them was not made by knights, as would have been seemly, and remain motionless at their post.
The men of Soissons, meanwhile, see no need of dealing softly with them and humoring them, so thrust them roughly, upset them from their horses, slay a many of them, and force them to leave their place or defend themselves, willy nilly.

At last, the Chevalier Eustace, scorning the burghers and proud of his illustrious ancestors, moves out into the middle of the plain, and with haughty voice, roars, "Death to the French!" The battle soon became general and obstinate; it was a multitude of hand-to-hand fights in the midst of a confused melley.
In this melley, the knights of the Emperor Otho did not forget the instructions he had given them before the engagement: they sought out the King of France himself, to aim their blows at him; and ere long they knew him by the presence of the royal standard, and made their way almost up to him.

The communes, and chiefly those of Corbeil, Amiens, Beauvais, Compiegne, and Arras, thereupon pierced through the battalions of the knights and placed themselves in front of the king, when some German infantry crept up round Philip, and with hooks and light lances threw him down from his horse; but a small body of knights who had remained by him overthrew, dispersed, and slew these infantry, and the king, recovering himself more quickly than had been expected, leaped upon another horse, and dashed again into the melley.
