The force under the command of the Constable de Montmorency, inside the walls of Paris, was known to be enormously superior in strength; and the Huguenots were unable to understand why he did not come out to give them battle. They knew, however, that Count Aremberg was on his way from the Netherlands, with seventeen hundred horse, sent by the Duke of Alva to the support of the Catholics; and they supposed that Montmorency was waiting for this reinforcement.
On the 9th of November news arrived that Aremberg was approaching, and D'Andelot, with five hundred horse and eight hundred of the best-trained arquebusiers, was despatched to seize Poissy, and so prevent Aremberg entering Paris.
The next morning the Constable, learning that Conde had weakened his army by this detachment, marched out from Paris. Seldom have two European armies met with a greater disparity of numbers; for while Conde had but fifteen hundred horse and twelve hundred foot, the Constable marched out with sixteen thousand infantry, of whom six thousand were Swiss, and three thousand horse. He had eighteen pieces of artillery, while Conde was without a single cannon.
As soon as this force was seen pouring out from the gates of Paris, the Huguenot trumpets blew to arms. All wore over their coats or armour a white scarf, the distinguishing badge of the Huguenots; and the horsemen were divided into three bodies. De la Noue and his following formed part of that under the personal command of Conde.
"We longed to be here in time for this battle, Philip," Francois said; "but I think this is rather more than we bargained for. They must be nearly ten to one against us. There is one thing: although the Swiss are good soldiers, the rest of their infantry are for the most part Parisians, and though these gentry have proved themselves very valiant in the massacre of unarmed Huguenot men, women, and children, I have no belief in their valour, when they have to meet men with swords in their hands. I would, however, that D'Andelot, with his five hundred horse and eight hundred arquebusiers, all picked men, were here with us; even if Aremberg, with his seventeen hundred horse, were ranged under the Constable.
"As it is, I can hardly believe that Conde and the Admiral will really lead us against that huge mass. I should think that they can but be going to manoeuvre so as to fall back in good order, and show a firm face to the enemy. Their footmen would then be of no use to them and, as I do not think their horse are more than twice our strength, we might turn upon them when we get them away from their infantry, and beyond the range of their cannon."
As soon, however, as the troops were fairly beyond the gates of Saint Denis, the leaders placed themselves at the head of the three columns and, with a few inspiring words, led them forward. Coligny was on the right; La Rochefoucauld, Genlis, and other leaders on the left; and the column commanded by Conde, himself, in the centre.
Conde, with a number of nobles and gentlemen, rode in front of the line. Behind them came the men-at-arms with lances, while those armed only with swords and pistols followed.
Coligny, on the right, was most advanced, and commenced the battle by charging furiously down upon the enemy's left.
Facing Conde were the great mass of the Catholic infantry but, without a moment's hesitation, the little band of but five hundred horse charged right down upon them. Fortunately for them it was the Parisians, and not the Swiss, upon whom their assault fell. The force and impetus of their rush was too much for the Parisians, who broke at the onset, threw away their arms, and fled in a disorderly mob towards the gates of Paris.
