Alva laid siege to Mons.

A Huguenot force of some three thousand men, led by the Sieur de Genlis, marched to its relief; but was surprised, and utterly routed, within a short distance of the town--1200 were killed on the field of battle, some 1900 fugitives were slain by the peasantry, barely a hundred reached Mons.
Coligny, who was preparing a much larger force for the assistance of Louis of Nassau, still strove to induce the king to throw himself heart and soul into the struggle against Spain; and even warned him that he would never be a true king, until he could free himself from his mother's control and the influence of his brother Anjou.
The queen mother, who had spies everywhere, was not long in learning that Coligny had given this advice, and her hatred against him was proportionately increased.

She at once went in tears to Charles, and pointed out to him that it was to her counsel and aid, alone, that he had owed his success against the Huguenots; that they were now obtaining all the advantages for which they had fought, in vain; and that he was endangering the safety of his throne by angering Spain, relying only on the empty promises of the faithless Queen of England.
Charles, always weak and irresolute, succumbed at once to her tears and entreaties, and gave himself up altogether to her pernicious counsels.
After the death of the Queen of Navarre the countess travelled back to Laville, escorted by her son and Philip.

The young men made no stay there, but returned at once to Paris where, now that Coligny was in the king's counsels, there was no ground for fear, and the approaching nuptials of the young King of Navarre would be attended by large numbers of his adherents.

They took a lodging near that occupied by the Admiral.
De la Noue was not at court, he being shut up in Mons, having accompanied Louis of Nassau in his expedition.
