As they were far more numerous than the French, the king saw them suddenly outflanking his right wing and apparently prepared to surround it; at the same moment loud cries were heard from a direction facing the centre: this meant that the Stradiotes were crossing the river to make their attack.
The king at once ordered his division into two detachments, and giving one to Bourbon the bastard, to make head against the Stradiotes, he hurried with the second to the rescue of the van, flinging himself into the very midst of the melee, striking out like a king, and doing as steady work as the lowest in rank of his captains.

Aided by the reinforcement, the rearguard made a good stand, though the enemy were five against one, and the combat in this part continued to rage with wonderful fury.
Obeying his orders, Bourbon had thrown himself upon the Stradiotes; but unfortunately, carried off by his horse, he had penetrated so far into the enemy's ranks that he was lost to sight: the disappearance of their chief, the strange dress of their new antagonists, and the peculiar method of their fighting produced a considerable effect on those who were to attack them; and for the moment disorder was the consequence in the centre, and the horse men scattered instead of serrying their ranks and fighting in a body.

This false move would have done them serious harm, had not most of the Stradiotes, seeing the baggage alone and undefended, rushed after that in hope of booty, instead of following up their advantage.

A great part of the troop nevertheless stayed behind to fight, pressing on the French cavalry and smashing their lances with their fearful scimitars.

Happily the king, who had just repulsed the Marquis of Mantua's attack, perceived what was going on behind him, and riding back at all possible speed to the succour of the centre, together with the gentlemen of his household fell upon the Stradiotes, no longer armed with a lance, for that he had just broken, but brandishing his long sword, which blazed about him like lightning, and--either because he was whirled away like Bourbon by his own horse, or because he had allowed his courage to take him too far--he suddenly found himself in the thickest ranks of the Stradiotes, accompanied only by eight of the knights he had just now created, one equerry called Antoine des Ambus, and his standard-bearer.
