by Marshals d’Aumont and Biron he remained on horseback during a portion of the night, having ordered his officers to their tents and reconnoitred as well as he could the position of the enemy.  Towards morning he retired to his headquarters at Fourainville, where he threw himself half-dressed on his truckle bed, and although the night was bitterly cold, with no covering but his cloak.  He was startled from his slumber before the dawn by a movement of lights in the enemy’s camp, and he sprang to his feet supposing that the duke was stealing a march upon him despite all his precautions.  The alarm proved to be a false one, but Henry lost no time in ordering his battle.  His cavalry he divided in seven troops or squadrons.  The first, forming the left wing, was a body of three hundred under Marshal d’Aumont, supported by two regiments of French infantry.  Next, separated by a short interval, was another troop of three hundred under the Duke of Montpensier, supported by two other regiments of foot, one Swiss and one German.  In front of Montpensier was Baron Biron the younger, at the head of still another body of three hundred.  Two troops of cuirassiers, each four hundred strong, were on Biron’s left, the one commanded by the Grand Prior of France, Charles d’Angouleme, the other by Monsieur de Givry.  Between the Prior and Givry were six pieces of heavy artillery, while the battalia, formed of eight hundred horse in six squadrons, was commanded by the king in person, and covered on both sides by English and Swiss infantry, amounting to some four thousand in all.  The right wing was under the charge of old Marshal Biron, and comprised three troops of horse, numbering one hundred and fifty each, two companies of German riders, and four regiments of French infantry.  These numbers, which are probably given with as much accuracy as can be obtained, show a force of about three thousand horse and twelve thousand foot.

The Duke of Mayenne, seeing too late the advantage of position which he might have easily secured the day before, led his army forth with the early light, and arranged it in an order not very different from that adopted by the king, and within cannon-shot of his lines.  The right wing under Marshal de la Chatre consisted of three regiments of French and one of Germans, supporting three regiments of Spanish lancers, two cornets of German riders under the Bastard of Brunswick, and four hundred cuirassiers.  The battalia, which was composed of six hundred splendid cavalry, all noblemen of France, guarding the white banner of the Holy League, and supported by a column of three thousand Swiss and two thousand French infantry, was commanded by Mayenne in person, assisted by his half-brother, the Duke of Nemours.  In front of the infantry was a battery of six cannon and three culverines.  The left wing was commanded by Marshal de Rene, with six regiments of French and Lorrainers, two thousand Germans, six hundred French cuirassiers, and the mounted troopers of Count Egmont.  It is probable that Mayenne’s whole force, therefore, amounted to nearly four thousand cavalry and at least thirteen thousand foot.
