To the south, on the territory of the Electorate of Cologne, were Imperial Troops under Field Marshal Guillaume de Lamboy.

However, the Hessians did not engage in battle, but pulled back to a pre-prepared site between Grevenbroich and Wevelinghoven, in order to cross the river Erft there and make for Neuss.

In spite of outnumbering the Hessians almost two to one, the Imperial Army had to retreat after five hours of fighting during which 1,500 of their men were captured and 1,000 lost their lives.

The Imperials retreated to Bonn to refresh their troops while the Hessian encamped between Uerdingen and Linn remaining inactive until September.

News of the Peace of Westphalia reached the combatants at the end of October, with the Imperials at Höxter and the Hessians at Brakel.
