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, during the Eighty Years War and the Anglo–Spanish War in 1627. The Spanish Army, led by Hendrik van den Bergh, came to relieve Grol but too late. The siege lasted from 20 July until 19 August 1627, resulting in the surrender of the city to the Dutch army.
