Moreover, their alliance would assuredly deter any, who might otherwise range themselves with him, from taking up arms.

No Huguenot would fight by the side of a Spaniard; and although the Guises and the Catholic nobles allied themselves with Spain against Henri of Navarre, it was in a matter in which they deemed their religion in danger, while this is but a quarrel between Bouillon and the cardinal; and with Spain fighting against France in the Netherlands, they would not risk their lands and titles.

Bouillon had better have stood alone than have called in the Spaniards and Austrians.

We know whose doing that is, the Archbishop of Rheims, who is a Guise, and, methinks, from what I have seen of him, a crafty one.
"I am sure that neither the duke nor Soissons would, unless won over by the archbishop, have ever consented to such a plan, for both are honourable gentlemen, and Soissons at least is a Frenchman, which can hardly be said of Bouillon, whose ancestors have been independent princes here for centuries.

However, I fear that he will rue the day he championed the cause of Soissons.
