For the moment Henry IV. represented in the eyes of Europe the Protestant cause. He was supported by the Huguenots of France and by some of the Catholic noblemen and gentry. Against him were arrayed the greater portion of the Catholic nobles, the whole faction of the Guises and the Holy League, supported by Philip of Spain.

The party from Holland disembarked at mid-day on the 9th of March. Hearing rumours that a battle was expected very shortly to take place, Sir Ralph Pimpernel started at once with his mounted party for Dreux, which town was being besieged by Henry, leaving the two companies of foot to press on at their best speed behind him. The distance to be ridden was about sixty miles, and late at night on the 10th they rode into a village eight miles from Dreux. Here they heard that the Duke of Mayenne, who commanded the force of the League, was approaching the Seine at Mantes with an army of ten thousand foot and four thousand horse.

"We must mount at daybreak, gentlemen," Sir Ralph Pimpernel said, "or the forces of the League will get between us and the king. It is evident that we have but just arrived in time, and it is well we did not wait for our foot-men."
