The mareschal Montmorency, accompanied by many persons of distinction, and attended by a pompous equipage, was sent over to ratify the treaty; and was received at London with all the parade which suited the solemnity of the occasion.

The terror of the emperor's greatness had extinguished the ancient animosity between the nations; and Spain, during more than a century, became, though a more distant power, the chief object of jealousy to the English.
This cordial union between France and England, though it added influence to the joint embassy which they sent to the emperor, was not able to bend that monarch to submit entirely to the conditions insisted on by the allies.

He departed, indeed, from his demand of Burgundy as the ransom of the French princes; but he required, previously to their liberty, that Francis should evacuate Genoa, and all the fortresses held by him in Italy; and he declared his intention of bringing Sforza to a trial, and confiscating the duchy of Milan, on account of his pretended treason.

The English and French heralds, therefore, according to agreement, declared war against him, and set him at defiance.

Charles answered the English herald with moderation; but to the French he reproached his master with breach of faith, reminded him of the private conversation which had passed between them at Madrid before their separation, and offered to prove by single combat that he had acted dishonorably.
