There might also be an exchange of domain between the two every six months.

As for Wesel and Julich, they could remain respectively in the hands then holding them, or the fortifications of Julich might be dismantled and Wesel restored to the status quo.

The latter alternative would have best suited the States, who were growing daily more irritated at seeing Wesel, that Protestant stronghold, with an exclusively Calvinistic population, in the hands of Catholics.
The Spanish ambassador at Brussels remonstrated, however, at the thought of restoring his precious conquest, obtained without loss of time, money, or blood, into the hands of heretics, at least before consultation with the government at Madrid and without full consent of the King.
"How important to your Majesty's affairs in Flanders," wrote Guadaleste to Philip, "is the acquisition of Wesel may be seen by the manifest grief of your enemies.

They see with immense displeasure your royal ensigns planted on the most important place on the Rhine, and one which would become the chief military station for all the armies of Flanders to assemble in at any moment.
"As no acquisition could therefore be greater, so your Majesty should never be deprived of it without thorough consideration of the case.

The Archduke fears, and so do his ministers, that if we refuse to restore Wesel, the United Provinces would break the truce.
