"The Bearnese is poor but a gentleman of good family," said the cheerful Henry, and it remained to-be seen whether nationality, unity, legitimate authority, history, and law would be able to neutralise the powerful combination of opposing elements.
The king had been besieging Dreux and had made good progress in reducing the outposts of the city. As it was known that he was expecting considerable reinforcements of English ships, Netherlanders, and Germans, the chiefs of the league issued orders from Paris for an attack before he should thus be strengthened.
For Parma, unwillingly obeying the stringent commands of his master, had sent from Flanders eighteen hundred picked cavalry under Count Philip Egmont to join the army of Mayenne. This force comprised five hundred Belgian heavy dragoons under the chief nobles of the land, together with a selection, in even proportions, of Walloon, German, Spanish, and Italian troopers.
Mayenne accordingly crossed the Seine at Mantes with an army of ten thousand foot, and, including Egmont's contingent, about four thousand horse. A force under Marshal d'Aumont, which lay in Ivry at the passage of the Eure, fell back on his approach and joined the remainder of the king's army. The siege of Dreux was abandoned; and Henry withdrew to the neighbourhood of Nonancourt. It was obvious that the duke meant to offer battle, and it was rare that the king under any circumstances could be induced to decline a combat.
On the night of the 12th-13th March, Henry occupied Saint Andre, a village situated on an elevated and extensive plain four leagues from Nonancourt, in the direction of Ivry, fringed on three sides by villages and by a wood, and commanding a view of all the approaches from the country between the Seine and Eure. It would have been better had Mayenne been beforehand with him, as the sequel proved; but the duke was not famed for the rapidity of his movements. During the greater part of the night, Henry was employed in distributing his orders for that conflict which was inevitable on the following day. His army was drawn up according to a plan prepared by himself, and submitted to the most experienced of his generals for their approval. He then personally visited every portion of the encampment, speaking words of encouragement to his soldiers, and perfecting his arrangements for the coming conflict. Attended 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.
Very different was the respective appearance of the two armies, so far, especially, as regarded the horsemen on both sides. Gay in their gilded armour and waving plumes, with silken scarves across their shoulders, and the fluttering favours of fair ladies on their arms or in their helmets, the brilliant champions of the Holy Catholic Confederacy clustered around the chieftains of the great house of Guise, impatient for the conflict. It was like a muster for a brilliant and chivalrous tournament. The Walloon and Flemish nobles, outrivalling even the self-confidence of their companions in arms, taunted them with their slowness. The, impetuous Egmont, burning to eclipse the fame of his ill-fated father at Gravelines and St. Quintin in the same holy cause, urged on the battle with unseemly haste, loudly proclaiming that if the French were faint- hearted he would himself give a good account of the Navarrese prince without any assistance from them.
A cannon-shot away, the grim puritan nobles who had come forth from their mountain fastnesses to do battle for king and law and for the rights of conscience against the Holy League—men seasoned in a hundred battle- fields, clad all in iron, with no dainty ornaments nor holiday luxury of warfare—knelt on the ground, smiting their mailed breasts with iron hands, invoking blessings on themselves and curses and confusion on their enemies in the coming conflict, and chanting a stern psalm of homage to the God of battles and of wrath. And Henry of France and Navarre, descendant of Lewis the Holy and of Hugh the Great, beloved chief of the Calvinist cavaliers, knelt among his heretic brethren, and prayed and chanted with them. But not the staunchest Huguenot of them all, not Duplessis, nor D'Aubigne, nor De la Noue with the iron arm, was more devoted on that day to crown and country than were such papist supporters of the rightful heir as had sworn to conquer the insolent foreigner on the soil of France or die.
When this brief prelude was over, Henry made an address to his soldiers, but its language has not been preserved. It is known, however, that he wore that day his famous snow-white plume, and that he ordered his soldiers, should his banner go down in the conflict, to follow wherever and as long as that plume should be seen waving on any part of the field. He had taken a position by which his troops had the sun and wind in their backs, so that the smoke rolled toward the enemy and the light shone in their eyes. The combat began with the play of artillery, which soon became so warm that Egmont, whose cavalry—suffering and galled—soon became impatient, ordered a charge. It was a most brilliant one. The heavy troopers of Flanders and Hainault, following their spirited chieftain, dashed upon old Marshal Biron, routing his cavalry, charging clean up to the Huguenot guns and sabring the cannoneers. The shock was square, solid, irresistible, and was followed up by the German riders under Eric of Brunswick, who charged upon the battalia of the royal army, where the king commanded in person.
There was a panic. The whole royal cavalry wavered, the supporting infantry recoiled, the day seemed lost before the battle was well begun. Yells of "Victory! Victory! up with the Holy League, down with the heretic Bearnese," resounded through the Catholic squadrons. The king and Marshal Biron, who were near each other, were furious with rage, but already doubtful of the result. They exerted themselves to rally the troops under their immediate command, and to reform the shattered ranks.
