Spinola, then entering the territory of Cleve, took session of Orsoy, an
important place on the Rhine, besides Duren, Duisburg, Kaster,
Greevenbroek and Berchem. Leaving garrisons in these places, he razed
the fortifications of Mulheim, much to the joy of the Archbishop and his
faithful subjects of Cologne, then crossed the Rhine at Rheinberg, and
swooped down upon Wesel. This flourishing and prosperous city had
formerly belonged to the Duchy of Cleve. Placed at the junction of the
Rhine and Lippe and commanding both rivers, it had become both powerful
and Protestant, and had set itself up as a free Imperial city,
recognising its dukes no longer as sovereigns, but only as protectors.
So fervent was it in the practice of the Reformed religion that it was
called the Rhenish Geneva, the cradle of German Calvinism. So important
was its preservation considered to the cause of Protestantism that the
States-General had urged its authorities to accept from them a garrison.
They refused. Had they complied, the city would have been saved, because
it was the rule in this extraordinary campaign that the belligerents made
war not upon each other, nor in each others territory, but against
neutrals and upon neutral soil. The Catholic forces under Spinola or his
lieutenants, meeting occasionally and accidentally with the Protestants
under Maurice or his generals, exchanged no cannon shots or buffets, but
only acts of courtesy; falling away each before the other, and each
ceding to the other with extreme politeness the possession of towns which
one had preceded the other in besieging.

The citizens of Wesel were amazed at being attacked, considering
themselves as Imperial burghers. They regretted too late that they had
refused a garrison from Maurice, which would have prevented Spinola from
assailing them. They had now nothing for it but to surrender, which they
did within three days. The principal condition of the capitulation was
