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
