The Capture of Roermond was a minor siege during the Eighty Years' War which took place from 31 August to 1 September 1637. A Spanish army under Cardinal-Infante Ferdinand would successfully siege and seize Roermond from the Dutch just one week after his victory at Venlo. This siege battle and that of Venlo were originally targeted to draw Frederick Henry away from Berda and towards the Cardinal-Infante's army for what could have been a field battle. Frederick Henry would not be swayed by this attempt and was dedicated to sieging Breda and would eventually take it on 11 October.
