In 1590 an Anglo-Dutch force under Maurice and Vere respectively launched a campaign with the aim of taking Breda. In a remarkable feat, a small assault force hid in a peat barge before a successful surprise assault that captured the city. With Spanish forces in France supporting the Catholic League as well as in the Low Countries, Maurice was able to take advantage, and thus started the gradual recapture of the Netherlands. This was known by the Dutch as the 'Ten glory years'. Soon after Breda the Anglo-Dutch retook Zutphen and Deventer which restored English prestige after their earlier betrayals. After defeating the Spanish under the Duke of Parma at Knodsenberg in 1591 a new confidence in the army took shape. English troops by this time composed nearly half of the Dutch army. The reconquest continued with Hulst, Nijmegen, Geertruidenberg, Steenwijk, and Coevorden all being taken within the next two years. In 1593 a Spanish attempt led by Francisco Verdugo to recapture Coevorden ended in failure when the Anglo-Dutch under Maurice and Vere relieved the place during the Spring of 1594. Finally, the capture of Groningen in the summer of 1594 resulted in the Spanish army being forced out of the Northern provinces which led to the complete restoration of the seven provinces.
