The Battle of Zutphen was fought on 22 September 1586, near the village of Warnsveld and the town of Zutphen, the Netherlands, during the Eighty Years' War. It was fought between the forces of the United Provinces of the Netherlands, aided by the English, against the Spanish. In 1585, England signed the Treaty of Nonsuch with the States-General of the Netherlands and formally entered the war against Spain. Robert Dudley, Earl of Leicester, was appointed as the Governor-General of the Netherlands and sent there in command of an English army to support the Dutch rebels. When Alessandro Farnese, Duke of Parma and commander of the Spanish Army of Flanders, besieged the town of Rheinberg during the Cologne War, Leicester, in turn, besieged the town of Zutphen, in the province of Gelderland and on the eastern bank of the river IJssel.
