The Siege of Grol in 1627 was a battle between the Army of the Dutch Republic commanded by Frederick Henry, Prince of Orange and the Spanish controlled fortified city of Grol (now known as Groenlo), during the Eighty Years War in 1627. The Spanish army led by Hendrik van den Bergh came to relieve Grol, but it came too late. The siege lasted from 20 July until 19 August 1627, resulting in the surrender of the city to the army of the United Provinces.
