Duchy of Jülich
With the capitulation of Dorsten, Hesse-Cassel had lost the most important fortress on the right bank of the Lower Rhine and, in the aftermath, concentrated their efforts in the Hessian War, together with the so called Weimar Army in French service under Guébriant, on the left bank possessions of the Archbishopric of Cologne under Ferdinand of Bavaria and the neutral Duchy of Jülich under Wolfgang William.
